This document describes how to setup and administer the DC Maintenance Management System (DCMMS) application version 1.1.2+svn .
In addition Section 2.4, “Analysis” covers some data analysis options.
DCMMS is available from http://dcmms.sourceforge.net.
While it is possible to run DCMMS on other operating systems, this document focuses on the DCMMS administration under Windows.
Feedback on DCMMS is welcome and can be addressed to
<dcmms-info@lists.sourceforge.net>
.
DCMMS Developer Guide and DCMMS User Guide provide additional information about the application.
Professional DCMMS administrators should go through the certification process (See Chapter 3, Administrator Certification).
This document is available in different formats (PDF, HTML, CHM and DocBook XML) and languages (English and French).
A "\" at the end of the line in program listings means that the line continues in the next line.
This document uses Unified Modeling Language (UML) diagrams to illustrate various aspects of the DCMMS application.
For those not familiar with the UML symbology, Figure 1.1, “UML Legend” provides a basic UML legend.
The DCMMS application can be installed in a stand-alone setup or in a client-server environment.
Caution | |
---|---|
The DCMMS application is meant to run in an intranet environment. If you want to use the application over the internet you should protect it by a proper firewall and/or VPN setup. To run the application directly on an internet server would require a complete security audit of the application code. Regardless of the type of installation, it is important that the administrator stays up-to-date with the latest Apache, PostgreSQL, Windows and PHP releases to avoid security leaks. |
In addition to the outlined approach it might be possible to run a DCMMS on server on the internet if it is hardened with SSL and additional access control on the Apache side (E.g. client-side certificates).
Figure 1.5, “Component Diagram” gives overview of DCMMS and its components. Depending on the GIS data sources to be used, other components might be required or optional components could be removed.
The database components can run on other servers.
This section describes the hard- and software requirements of the DCMMS application.
A PC with at least 256 MB RAM and at least 1 GHz CPU speed.
The actual hardware requirements might be higher depending on the size and nature of the map data as well as the number of concurrent users.
To print the workorders, a printer with at least 300dpi resolution is required.
Tip | |
---|---|
Call-center grade headphones are strongly recommended in order to receive customer complaint calls. |
Tip | |
---|---|
An optical mouse is recommended for all DCMMS clients. |
The following software packages are required to run the DCMMS application:
PostgreSQL
PostGIS
Apache (Other web servers will also work)
PHP
The following PEAR modules:
DB
DB_DataObject
DB_DataObject_FormBuilder
Date
HML_Common
HTML_QuickForm
HTML_QuickForm_Controller
HTML_QuickForm_SelectFilter
HTML_Table
Image_Canvas
Image_Color
Image_Graph
Log
Pager
Mapserver (PHP Mapscript)
Web browser
Section 2.1, “Installation”covers the installation of all required software packages.
If it is intended to use the Arabic interface of the DCMMS application, the PostArabic software package is required in addition.
Caution | |
---|---|
While it might be possible to install the DCMMS server on other Windows flavors, only Windows 2003 Server and Windows XP are recommended. The filesystem of |
Windows XP,2000 installations have been tested and should work. Windows NT, 95, 98 are ME not recommended.
Installation of DCMMS on other operating systems such as Linux may require minor changes to the source code. Please contact the DCMMS developers if you are having problems. The initial DCMMS version was created on Linux.
On Windows, the following folders contain files that belong to the standard DCMMS installation:
+ c: | +--+ ms4w | | | +--+ Apache | | | | | +--- conf | | | | | +--- logs | | | +--+ apps | | | | | +--+ dmms | | | | | +--- conf | | | | | +--- data | | | | | +--- htdocs | | | | | +--- include | | | | | +--- plugin | | | +--+ httpd.d | | | +--+ tmp | | | +--- ms_tmp | +--+ Program Files | | | +--+ PostgreSQL | | | +--+ 8.3 | | | +--- data | +--+ windows | +--- fonts
Note | |
---|---|
Note that your actual folder structure might be different, e.g. when you use a Non-English version of Windows XP. Use the structure above as a reference when you're not sure where to install things. |
Tip | |
---|---|
If you are installing manually, you should install the software to the above mentioned folders. |
The PostgreSQL
folder holds the
PostgreSQL installation, the Apache2
folder
the Apache webserver and the php
folder the
PHP installation. The tmp
folder holds
temporary files (e.g. PHP session information) and the
ms_tmp
folder contains temporary map files
created by mapserver.
For most of the software packages these folders are the default on a system with an English version of the Windows operating system. The folders will be created during the installation process described below.
c:\ms4w\apps\dcmms\config
contains all
configuration files with the exception of c:\ms4w\apps\dcmms\include\dcmconfig.php
.
c:\ms4w\apps\dcmms\doc
contains the
documentation in various formats: CHM, DocBook XML, HTML, PDF.
c:\ms4w\apps\dcmms\data
contains GIS
data (shape files) used by the application. However this location
is not fixed and may be overridden in the map file.
c:\ms4w\apps\dcmms\plugin
contains
application plug-ins (extensions that extend the functionality).
Basic computer knowledge together with this guide should be sufficient to administer a stand-alone installation.
Any administrator will benefit from knowledge in SQL, PostgreSQL, the Windows command line interface (cmd.exe), Windows user administration, Windows services, GIS (e.g. ArcView), mailing lists - however such knowledge is not a requirement.
Various support possibilities are available to support new administrators (See Section 2.8.2, “Support Tracker”, Section 2.8.1, “DCMMS Info Mailing List”).
This section outlines important concepts that are relevant to the DCMMS administration.
This section introduces Windows services.
Apache and PostgreSQL run as Windows services.
To open the Services Panel, open the Control Panel from the Start Menu as shown in Figure 1.6, “Control Panel”.
In the Control Panel, click on the following icon:
Open the Services Panel by clicking on the this shortcut:
The Services Panel is displayed in Figure 1.7, “Services Panel”.
The Status column shows the services that are currently running. In Figure 1.7, “Services Panel” is running ("Started") while the Removable Storage is not running (empty Status column).
To start a service, click on the button.
To stop a service, click on the button.
In both cases, verify the success in the Status column of the service list.
For additional information on Windows services, consult your Windows documentation.
Important information on Windows user accounts.
Figure 1.8, “Windows Users” shows users that are important for the DCMMS administration. Note that the unpriviledged users account to operate DCMMS are omitted.
For additional information on Windows user accounts, consult your Windows documentation.
Note | |
---|---|
While the Windows user accounts "system" and "postgres", you don't have to know their passwords. |
Note | |
---|---|
The name of the Windows user account to run the PostgreSQL database service (default: postgres) can be changed during the PostgreSQL installation. |
Introduction to PostgreSQL user management.
Figure 1.9, “PostgreSQL Users” shows PostgreSQL users that are important for the DCMMS administration. Windows users and system boundaries are shown to clarify the relationships.The PostgreSQL documentation which you can access e.g. through the Start Menu (after PostgreSQL installation) or on the PostgreSQL website contains additional information on PostgreSQL user management.
Caution | |
---|---|
Don't get confused by the two "postgres" accounts: Even though they have the same name, they are different things, one lives inside PostgreSQL and one inside Windows. You don't have to know the password of the Windows account "postgres" (The PostgreSQL intaller is creating a long, random password for it), but you have to know the password of the PostgreSQL account "postgres". Please follow the PostgreSQL installation instructions carefully (Section 2.1.2.3, “PostgreSQL”). |
If you are going to use DCMMS in more than one language and would like to use the DCMMS translation system for your data, you should read this section.
DCMMS is actually using two translation systems: GNU gettext for
text that occurs in the PHP sources and the dcmmstranslation()
for text stored inside the PostgreSQL
database.
Note | |
---|---|
The |
Both gettext and dcmmstranslation()
will fall back to the two letter ISO language code in case no
translation is found for the five letter code (E.g. the "ar"
translation is returned if "ar_JO" was requested and no
translation was found).
GNU gettext is a widely used system for translation management.
DCMMS is using the PHP gettext extension, the translations are
edited in the locale/*/LC_MESSAGES/dcmms.po
files. Replace "*" with a two letter ("ar") or
five letter ("ar_JO") language code.
In order to be used by gettext, the source files (dcmms.po
) files have to be compiled to dcmms.mo
files.
Editing and compilation is conveniently done with poEdit (Section 2.1.6.3, “poEdit”). poEdit is also capable of extracting the translation terms from PHP sources.
Messages that have to be translated but are not included in the PHP
sources should be added to include/i18n.php
. This
is the case e.g. for coded values from the database.
Messages residing in the PostgreSQL database should be
internationalized using the dcmmstranslation()
.
The dcmmstranslation()
function looks up
translations from the Translation
table.
The name
field of the
AdministrativeArea
,
Landmark
and Village
should contain the name in the primary language that is used to
operate the application. E.g. in the case of landmarks, this is
the field that is filled and used if no other translation is given.
Additional translations are stored in the translation table.
To use translations, e.g. in map files, use the following statement:
dcmmstranslation('en', name)where 'en' is the ISO code of the language you want to use.
If no matching translation is found in the translation table,
the term to translate is returned by dcmmstranslation()
.
DCMMS allows to use language-specific map files.
The application replaces "%s" with the two-letter ISO
language in the following dcmconfig.php
configuration option:
$_SESSION["strMapFile"] = "conf/sample_%s.map";
This way it is possible to encapsulate language specific information in the map files.
PostGIS layers used in the map files can use the dcmmstranslation()
function for translation.
See also Section 2.2.2, “Custom Map”
Mailing lists are automated distribution systems for emails.
The majority of the software products mentioned in this document offer a multitude of mailing lists to keep users and administrators updates about the latest releases as well as potential security issues.
Tip | |
---|---|
If you are not familiar with mailing lists yet, take the time to familiarize with the techniques to subscribe and to post to them. |

How to install DCMMS manually.
Note | |
---|---|
This section might be useful only for installations on non-Windows platforms and for developers who are interested in the details of the DCMMS installation process. |
Tip | |
---|---|
The DCMMS installer sources (e.g.
|
Caution | |
---|---|
The following expects that various PostgreSQL binaries, such as psql.exe or createlang.exe are in the PATH. If necessary, you have to change your PATH environment variable to include the bin folder of your PostgreSQL installation. |
The PostgreSQL database is available from http://www.postgresql.org.
The PostgreSQL installation should support UNICODE.
Warning | |
---|---|
You may run into problems if you use a binary PostgreSQL distribution under Linux or UNIX. In order to use PostGIS and specifically GEOS from PostgreSQL, the binaries have to be linked against libstc++. The PostGIS documentation contains details regarding this issue. |
In order to enforce DCMMS logins with
password authentication, the pg_hba.conf
configuration file should be altered like in the following example:
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD host all postgres 127.0.0.1 255.255.255.255 trust host dcmms all 127.0.0.1 255.255.255.255 password
Note that this still allows the PostgreSQL superuser postgres to connect to PostgreSQL server without authentication. However the user postgres is not allowed to log on to DCMMS.
Note | |
---|---|
The instructions below assume that the PostgreSQL administrator is named postgres and that the postmaster is running on the local machine (localhost). If this is not the case for you, you'll have to adjust the commands accordingly. The same applies to the connection method - if your postmaster is not configured to accept TCP/IP connections, you have to adjust the commands (and possibly the DCMMS configuration). |
Create a new database named dcmms using UNICODE, load the PL/SQL language to the database:
createdb -U postgres -h localhost --encoding=UNICODE dcmms createlang -U postgres -h localhost plpgsql dcmms
If PL/SQL was created in template1, the second command will fail. Ignore the error message in this case.
PostGIS is available from http://postgis.refractions.net .
Follow the installation instructions in the PostGIS documentation.
Once PostGIS is installed, change to the
directory containing
postgis.sql
and
spatial_ref_sys.sql
and load
PostGIS to the dcmms
database:
psql -U postgres -h localhost -f postgis.sql dcmms psql -U postgres -h localhost -f spatial_ref_sys.sql dcmms
PostArabic is a small module that adds Arabic shaping functionality to PostgreSQL.
Tip | |
---|---|
The PostArabic installation is only required in order to display Arabic map labels. If you are not interested in Arabic map labels, you can skip the PostArabic installation. |
The PostArabic sources are available from the DCMMS download page.
Follow the installation instructions in the file
README.arabic
.
Change to the directory containing arabic.sql
and load PostArabic to the
dcmms database:
psql -U postgres -h localhost -f arabic.sql dcmms
DCMMS allows the fuzzy search of landmarks. Through the fuzzy search, landmarks can be found even if the search term was misspelled.
The fuzzystrmatch module of the PostgreSQL distribution is used for this purpose.
To compile and install the fuzzystrmatch
module, go to the contrib
folder of your
PostgreSQL source tree and execute the
following commands:
make make install psql -U postgres -h localhost -f fuzzystrmatch.sql
If you are using the Windows PostgreSQL installer, you find
fuzzystrmatch.dll
in
c:\Program Files\PostgreSQL\8.1\share\contrib
.
The Apache webserver is available from http://httpd.apache.org .
Follow the installation instructions in the Apache documentation.
Apache is configured through the
httpd.conf
file. In order to access
the DCMMS application by a convenient
URL like http://localhost/dcmms/, you should add lines like the
following to httpd.conf
:
Alias /dcmms "c:/program files/dcmms/" <Directory "c:/program files/dcmms"> Options Indexes Multiviews </Directory> Alias /ms_tmp/ "c:/tmp/ms_tmp/"
The second alias line configures the location of temporary files created by PHP/Mapscript. You will have to adjust the DCMMS sources to use the same alias and path. Adjust the path names according to your DCMMS installation path.
The PHP scripting language is available from www.php.net.
DCMMS is currently using PHP 4.*. Use of DCMMS with PHP 5.0 will require some small changes to the application and is not recommended yet. Please contact the DCMMS developers if PHP 5.0 is a requirement for your installation.
Follow the installation instructions in the PHP documentations.
Note | |
---|---|
If you don't install PHP to
|
Caution | |
---|---|
Because of previous PHP/Mapscript limitations, it is recommended to install PHP as a CGI command. The use of PHP as an Apache module is not very well tested with DCMMS and may lead to instabilities. If you are testing such a setup, please share your experiences with the DCMMS developers. |
The installation can be completed with the following three lines
in httpd.conf
:
ScriptAlias /php/ "c:/windows/php/" AddType application/x-httpd-php .php Action application/x-httpd-php "/php/php.exe"
Again, make sure that the path names above match the ones on your system.
Add the following DCMMS-specific configuration
settings to c:\windows\php.ini
:
default_mimetype = "text/html" default_charset = "utf-8" include_path = ".;c:\windows\php\pear" error_reporting = E_ALL & ~E_NOTICE extension_dir = "c:/windows/php/extensions" enable_dl = On allow_call_time_pass_reference = On file_uploads = On upload_tmp_dir = c:\tmp upload_max_filesize = 20M extension=php_gd2.dll extension=php_gettext.dll extension=php_pgsql.dll extension=php_zip.dll extension=php_mapscript_46.dll [Session] session.save_path = c:/tmp

In order to use gettext in PHP on Linux, the PHP safe mode
has to be enabled. The reason is that the safe_mode = On |
On Windows, install the mapserver distribution with PHP/Mapscript, which is available from the internet under http://maptools.org.
On other operating systems, install PHP/Mapscript from the Mapserver distribution which is available from http://mapserver.gis.umn.edu/index.html.
Make sure that the PHP/Mapscript extension is loaded in
php.ini
.
Note | |
---|---|
You'll need a PHP/Mapscript binary compiled with PostGIS support. |
The DCMMS source tarball is available from http://dcmms.sourceforge.net.
The SQL scripts
create_dcmms_ddl.sql
and
create_views.sql
in the
script
folder of the DCMMS
distribution create users and data model for the application.
Change the directory to the script
folder
and run the scripts on the dcmms database:
psql -U postgres -h localhost -f create_dcmms_ddl.sql dcmms psql -U postgres -h localhost -f create_views.sql dcmms
Copy the default configuration file,
include/dcmconfig.php.default
to
include/dcmconfig.php
.
Review the settings in dcmconfig.php
and
adjust if necessary.
Copy the default DataObject configuration file
conf/dataobject.ini.default
to
conf/dataobject.ini
.
Review the settings in dataobject.ini
and adjust if necessary - especially all settings that include
a path.
Copy the default identify plugin configuration file
conf/identifyplugin.ini.default
to
conf/identifyplugin.ini
.
Review the settings in identifyplugin.ini
and adjust if necessary - especially all settings that include
a path.
You should now be able to log on to the DCMMS application, using a URL like http://localhost/dcmms.
A sample data set is available from the DCMMS download page.
Unpack the files to the data
folder of your
DCMMS installation.
Load the AdministrativeArea, Village and Landmark shapefiles to the database. This can be done using Gshp2pgsql (Section 2.3.1, “GIS Data Loading”) or using the following commands from the commandline:
set PGCLIENTENCODING=WINDOWS-1256 psql -d dcmms -U postgres -h localhost -f administrativearea.sql psql -d dcmms -U postgres -h localhost -f village.sql psql -d dcmms -U postgres -h localhost -f landmark.sqlIn this case, the commands have to be executed in the
data
folder.Upon first installation, the DCMMS application will provide two default PostgreSQL (DCMMS) users:
User dcmms with password dcmms.
User admin with password admin.
As the name indicates, admin has administrator rights, whereas the user dcmms has not.
See Section 1.4.3, “PostgreSQL users” for detailed information on Windows and PostgreSQL users.
Caution | |
---|---|
On production systems, you should change the default passwords as soon as possible for security reasons. |
The following points should be checked before a DCMMS goes into production:
Administrator passwords on the Windows and PostgreSQL level
System clock setting
User rights (use the Windows "guest" account if possible for DCMMS users)
Security updates
Network connections including Firewall
Eventually all removable media drives should be disabled to prevent installation of software (applies to standalone systems that should be specially hardened).
The PostgreSQL timezone setting. If necessary,
adjust postgresql.conf
, e.g. by adding
a line like
timezone = 'GMT-3'
You can check the timezone setting by the following SQL statement:
select now()
Failure to configure the timezone correctly will result in the following error message in the logon page: Configuration Error: PHP Time != PostgreSQL time.
See also Section 2.8.6, “Configuration error: PHP time != PostgreSQL time”.
This section describes the installation of various optional tools that ease the DCMMS administration and configuration.

PERL is the programming language used for some PostGIS
maintenance tools like postgis_restore.pl
.
On other operating systems like Linux, you will most likely be able to use the PERL distribution that is already installed.
GIX is an ArcView 3.* extension that allows to export views to mapserver map files.
GIX is available from http://gix.sourceforge.net.
Note | |
---|---|
You can only use fragments from the map files created by GIX as ArcView 3.* does not support PostGIS. |
See Section 2.2.2, “Custom Map” for details regarding the DCMMS map files.
To edit the dcmms.po
files,
poEdit is recommended. It is freely available
from http://poedit.sourceforge.net.
Tip | |
---|---|
Install poEdit version 1.3.1 or higher. |
In order to extract the translation messages from the PHP sources, the following settings should be applied.
Start poEdit.
Select
from the menu.Select the Parser tab and click on the button.
Fill in the settings as shown in Figure 2.57, “poEdit PHP parser settings”
Close the dialogs.
Open a dcmms.po
file.
Choose
from the menu.In the Paths tab, add the path to the DCMMS source as shown in Figure 2.58, “Catalog Path”
Caution | |
---|---|
Make sure that you enter the actual path to the DCMMS sources on your system. |
Once the settings above have been applied, it is possible to update the catalog by selecting
from the menu.See also Section 1.4.4, “Translation System”.
The R statistical analysis package can be used for the analysis. R is available from http://www.r-project.org/.
R can be used e.g. to analyze the pressure dependency of maintenance events (Section 2.4.2, “Pressure Dependency”).
This section describes how to configure DCMMS after successfull installation.
The file include/dcmconfig.php
contains the
configuration of the DCMMS application.
A default configuration file is stored under
include/dcmconfig.php.default
. Copy this file to
include/dcmconfig.php
if necessary.
The configuration file can be edited using any text editor.
All other configuration files can be found in the conf
folder: c:\ms4w\apps\dcmms\conf
.
The PHP configuration file php.ini
is installed
by default under c:\windows
.
The intSRID
variable in dcmconfig.php
is used to specify the spatial referencing
system identifier for your spatial data. The PostGIS documentation
contains detailed information about spatial reference systems. PostGIS
stores SRIDs in the spatial_ref_sys table. A value of "-1" can be
used in case no real SRID is available. However, the specification of
an SRID is very important in order to expose the data through services
like WMS.
How to use your own maps with DCMMS.
Create your own map file(s) and edit the following line in
dcmconfig.php
to point to this file:
$_SESSION["strMapFile"] = "conf/sample_%s.map";
Warning | |
---|---|
When customizing the map files, make sure to use
other names than Adjust |
In the default configuration, you need one map file for every language (%s will be replaced with the two-letter ISO language code).
If you would like to use DCMMS in more than one language, please also read Section 1.4.4, “Translation System”.
Note | |
---|---|
The "DESCRIPTION" metadata information must be provided for layers that return results for the identify tool. In addition, the "TEMPLATE" has to be set for the respective class. |
The following layers are required and should be copied from the sample files:

ArcView 3.* users may want to use the GIX extension to transfer symbology from ArcView to the mapserver map file. |
The mapserver documentation available from http://mapserver.gis.umn.edu/ contains detailed information about the mapfile syntax.
Tiled shapefiles allow mapserver to maximize performance for large shapefile datasets.
The ngwa.map
map file
provides an example of tiled shapefile usage.
Please refer to the mapserver documentation for details on tiled shapefiles.
Tip | |
---|---|
Use the tileindex.exe from the mapserver distribution to create tile indexes. |
Caution | |
---|---|
Uniform shapefiles have to be used when they are tiled. They have to have exactly the same number of fields in the same order. |
To re-order shapefile fields using ArcView 3.*, follow these steps:
Open a View.
Add the shapefile as a Theme to the View.
Open the attribute table.
Drag and drop the field headers until they are in the correct order.
Go back to the View.
Select
-> .The DCMMS application replaces the dummy user name and password in the mapfile with the information provided by the user when logging on. Example 2.1, “PostGIS Connection Example” shows an example PostGIS connection line from a mapfile.

CONNECTION "dbname=dcmms user=dummy password=dummy host=localhost"
Important | |
---|---|
Make sure that the PostgreSQL "dcmmsuser" group has the right to select from the tables used for your PostGIS layers. |
Tiled images allow mapserver to maximize performance for large raster datasets.
The following steps are required to prepare the tiled images, and include them on the map file.
Please refer to the mapserver documentation for details on tiled images.
Use the gdaltindex.exe from the mapserver distribution to create tile indexes.
Example of usage:
gdaltindex sana_index.shp *.tif
Tip | |
---|---|
In order to increase the display, and rendering performance of the images it is prefered to create over views for these images using the following command: gdaladdo -r average imagename.tif 2 4 8 16 32 64 128 |
You can add the tiled images on the map file using the following statements:
LAYER NAME "satellite" STATUS default TILEINDEX "c:\ms4w\apps\dcmms\tiff\image_index.shp" TILEITEM "Location" TYPE RASTER END
Tip | |
---|---|
When using raster data, it is recommended to change the IMAGETYPE parameter to "JPEG" as it offers good compression for raster data. |

Plug-Ins provide configurable and extensible ways to extend the application functionality in a way that is compatible with future releases of the the software.
Plug-ins for the identify tool of the map page allow to extend the functionality of the application.
The plug-ins are configured in
conf/identifyplugin.ini
. The file is a simple
text file that can be edited with any text editor.
DCMMS comes with the ImageIdentifyPlugin
- see Section 2.2.3.1.1, “Image Identify Plug-In” for details.
Example 2.2. Excerpt from identifyplugin.ini
; Configuration file for map.php plug-ins [IdentifyPlugin] Plugin1 = ImageIdentifyPlugin Layer1 = village ;Plugin2 = ??? ;Layer2 = ???
Lines starting with ";" are comments and are ignored.
Section header of the IdentifyPlugin section.
The class ImageIdentifyPlugin
(from plugin/imageidentifyplugin.php
) will be
loaded as the first plug-in. The configuration line for the second
plug-in starts with "Plugin2"
The first plug-in will be used when the identify tool selects features in the "village" layer.
The configuration lines for the second plug-in are commented out, this plug-in has been disabled.
Note that identifyplugin.ini
can also contain
configuration options for the individual plug-ins (in different
sections). See the "[Plugin1]", "[Plugin2]", ...
sections for details.
Search plug-ins allow additional search functionality to be added to the find tool that is displayed on every page. Use of search plug-ins is triggered by configurable keywords that are followed by a colon (":") and the search term itself.
Search plug-ins are easy to implement. The DCMMS Developer Guide contains the details.
The search plug-ins are configured in
conf/searchplugin.ini
. The file is a simple
text file that can be edited with any text editor.
DCMMS includes the CustomerSearchPlugin
-
see Section 2.2.3.2.1, “Customer Search Plug-In” for details.
Example 2.3. Excerpt from searchplugin.ini

parameters for the
The first plug-in (CustomerSearchPlugin
will be executed when the keyword "customer"
is used (e.g. using the search term "customer:311").
An additional plug-in can be added by uncommenting this line and replacing the question marks with the plug-in class name.
This header starts the configuration section for Plugin1, in
this example the CustomerSearchPlugin
.
See Section 2.2.3.2.1, “Customer Search Plug-In” for details.
The customer search plug-in allows to find customer locations on their map using a numeric identifier like the contract number.
Geocoded customer locations (polygons) are required in order to use the
plug-ins functionality. The CustomerSearchPlugin
class in plugin/customersearchplugin.php
contains the
implementation.
The plug-in assumes a two table structure where the first table (customer) contains the search term (customer ID) and the geocode as a foreign key. The second table (building) contains the geocode and the polygon geometry that will be used to determine the map extent. The relationship between customer and building is one-to-many.
Example 2.4, “Customer Search Plug-In Configuration” contains a snippet
from searchplugin.ini
with an example
CustomerSearchPlugin
configuration.
Example 2.4. Customer Search Plug-In Configuration
[Plugin1] ; PEAR DB Data Source Name (DSN). See PEAR DB documentation for details. DSN = pgsql://dcmms:dcmms@localhost/customer ; Name of the table that contains customer id and geocode. CustomerTable = customer ; Name of the id field in the customer table. Should be indexed. CustomerID = id ; Name of the geocode field in the customer table CustomerGeocode = geocode ; Name of the table that contains geocode and polygon geometry. Should be indexed. BuildingTable = building ; Name of the geocode field in the building table BuildingGeocode = nwsa_pk ; Name of the geometry field in the building table BuildingGeometry = the_geom
Section "Plugin1" contains the
CustomerSearchPlugin
configuration if
CustomerSearchPlugin
was registered as
Plugin1 (See Example 2.3, “Excerpt from searchplugin.ini”).
Lines starting with ";" are comments.
In this case, the customer database from the PostgreSQL server running on localhost will be used with the user name dcmms and the password dcmms.
The "customer" table will be queried for the search term (ID) provided by the user.
The "id" field of the customer table contains the customer id.
The "geocode" field of the customer table will be used to join the building table (foreign key).
The "building" table will be joined against the customer table. It contains the geographic information.
The "nwsa_pk" field (primary key) will be used to join the customer table.
The "the_geom" field of the building table contains the polygon geometry that will be used to determine the map extent.

This section describes various tasks related to the DCMMS administration.
This section discusses various ways to load GIS data in various formats to the dcmms database.
Tip | |||
---|---|---|---|
Not all GIS data used by the application has to be loaded to the database. Data that is only displayed on the map and not used otherwise in the application can be kept in its original format and location if it is supported by Mapserver. This is the case for shapefiles. Unless you are restoring a backup, only the following three layers of GIS data have to be loaded to the DCMMS database:
|
Besides the options described in the following sections, tools like ogr, QGIS or FME can also be used to load the data.
If you would like to load and use data in multiple languages, an understanding of the translation system (Section 1.4.4, “Translation System”) is required.
Tip | |
---|---|
For ArcView 3.x users, the AV PostGIS Connection extension is the preferred way to load shapefiles to PostGIS: |
When loading certain shapefiles to the DCMMS database, it might
be required to drop the views before loading and to restore them
after loading. The scripts script/drop_views.sql
and script/create_views.sql
can be used for this
purpose.
Note | |
---|---|
Data that is edited in DCMMS uses sequences to determine the next primary key. For this reason it might be necessary to adjust a sequence if certain shapefiles are loaded. One example is the landmark table. The following SQL statement shows how to set the correct start value for the sequence after the landmark shapefile is loaded: select setval('landmark_seq', max(gid) from landmark); |
Note | |
---|---|
You may also want to update the |
The commandline tool shp2pgsql is part of the PostGIS distribution and used internally by Gshp2pgsql. It allows to load shapefiles to PostGIS tables.
Make sure that shp2pgsql.exe and psql.exe are in the path:
PATH=%PATH%;c:\Program Files\PostgreSQL\8.1\bin
If necessary, adjust the encoding used by
psql through the
PGCLIENTENCODING
environment variable:
set PGCLIENTENCODING=WINDOWS-1256
Before the AdministrativeArea
,
Landmark
or Village
shapefiles are loaded to the database, the DCMMS views have to
be dropped:
psql -d dcmms -U postgres -f \ "c:\ms4w\apps\dcmms\script\drop_views.sql"
Load the shapefile to the database:
shp2pgsql -d -D landmark.shp landmark > landmark.sql psql -d dcmms -U postgres -f landmark.sql
If the table does not exist in your database yet, omit the "-d" option when calling shp2pgsql. See the shp2pgsql documentation for details.
Recreate the views if necessary:
psql -d dcmms -U postgres -f \ "c:\ms4w\apps\dcmms\script\create_views.sql"
How to prepare AdministrativeArea
,
Village
and Landmark
layers to be loaded to the application.
The features of AdministrativeArea
shall not overlap and cover the whole area where landmarks are
possibly inserted. The features of Village
shall not overlap and cover the whole area where
landmarks are possibly inserted. It is recommened to create a
rectangular covering area around both classes.
The application expects the administra
field in Landmark
shall be filled with the
CodedValue
from the
AdministrativeArea
that contains (intersects) the
landmark.
In case you have the unit cost information saved in an Excel sheet, to load unit cost information to the PostgreSQL database do the following:
Delete all the fields from the file except for the folowing fields:
ID
Diameter1
Diameter2
Price
Unit ID (The Subtype in Material, Staff or Equipment)
Important | |
---|---|
You should keep the same fields order and Delete the names of the field. |
Save the Excel sheet file as a "Text(Tab delimited)" file
Execute the following SQL statements for the Material cost file:
delete from materialcost; copy materialcost from 'D:\\sandbox\\water\\dcmms\\txt_cost_sheet.txt' with NULL as '' delimiter as '\t';

You can use pgAdmin III as well as the commandline tools pg_dump or pg_dumpall to backup your DCMMS database. Please refer to the pgAdmin III and PostgreSQL documentation for detailed information on how to perform the backups. In addition, the instructions below explain how to backup the database using the PostgreSQL command line tool pg_dumpall. |
For all GIS data displayed in the DCMMS maps, follow your usual backup strategies.
In order to backup the content of the DCMMS database, do the following:
Open a Windows commandline (e.g. by executing %SYSTEMROOT%\system32\cmd.exe).
Execute the command below to create a dump file
of the database. The dump file will be saved as
c:\dcmms-backup.sql
.
pg_dumpall -c -U postgres -h localhost > c:\dcmms-backup.sql
Caution | |
---|---|
You have to make sure that pg_dumpall is in your PATH. |
Write the dump file to a suitable backup media (e.g. a rewritable CD-ROM or a tape) and store it in a safe place.
Important | |
---|---|
Make sure that you also backup your map and
configuration and symbol files ( |
Tip | |
---|---|
Restore is available through pgAdmin III as well as the commandline tools psql or pg_restore. Please refer to the pgAdmin III and PostgreSQL documentation for details how to restore a database dump. In addition, the instructions below explain how to restore the database using the PostgreSQL command line tool psql. |
Restore all the GIS data used in the map from your GIS data backups.
In order to restore a previous dump file of the DCMMS database, execute the following commands:
Open a Windows commandline (e.g. by executing %SYSTEMROOT%\system32\cmd.exe).
Restore the dump file:
psql -f c:\dcmms-backup.sql -U postgres -h localhost -d dcmmsWhere
c:\dcmms-backup.sql
is the
path to the dump file - adjust this accordingly if your dump file
is not c:\dcmms-backup.sql
. Alternatively,
you can copy your dump file to
c:\dcmms-backup.sql
You may be asked to enter the password of the PostgreSQL superuser "postgres".
Tip | |
---|---|
Remember to drop the database and create an empty one before restoring your backup. Use "UTF-8" as the database encoding when creating the database. |
This section describes the necessary steps to merge workorders, maintenance records and resource information from two DCMMS databases.
Before the data from the databases can be merged, it has to be ensured that the two different databases use different workorder numbers. In the following example, the workorder numbers will be shifted by a 1,000,000 offset to achieve this namespace separation. To shift existing DCMMS records to another number "namespace", the following SQL commands can be used:
alter table maintenance drop constraint "$1"; alter table resource drop constraint "$1"; update workorder set id=id+1000000; update maintenance set id=id+1000000; update resource set maintenanceoid=maintenanceoid+1000000; update resource set id=id+1000000; update seal set id=id+1000000; update history set id=id+1000000; update history set recordoid=recordoid+1000000; alter table maintenance add constraint "$1" foreign key(id) references workorder(id); alter table resource add constraint "$1" foreign key(maintenanceoid) references maintenance(id);
This shift should be accompanied with re-setting the sequence numbers with the same offset as demonstrated with the SQL commands below:
drop sequence history_seq; drop sequence landmark_seq; drop sequence workorder_seq; drop sequence ResourceID; drop sequence seal_seq; create sequence history_seq start 1000000; create sequence landmark_seq start 1000000; create sequence workorder_seq start 1000000; create sequence ResourceID start 1000000; create sequence seal_seq start 1000000;
Once the workorder IDs are unique throughout both databases, a special database dump can be created from the first database using the following commands in the Windows commandline:
pg_dump -U postgres -t history -D -a dcmms > dcmms_merge.sql pg_dump -U postgres -t workorder -D -a dcmms >> dcmms_merge.sql pg_dump -U postgres -t maintenance -D -a dcmms >> dcmms_merge.sql pg_dump -U postgres -t equipment -D -a dcmms >> dcmms_merge.sql pg_dump -U postgres -t material -D -a dcmms >> dcmms_merge.sql pg_dump -U postgres -t staff -D -a dcmms >> dcmms_merge.sql pg_dump -U postgres -t seal -D -a dcmms >> dcmms_merge.sql
Before merging the data into the second database, all data in the namespace of the first database have to be deleted. For example by using an SQL statement like the following:
select purgeWorkorder(ID) from Workorder where ID > 1000000
The dump file dcmms_merge.sql
can be
restored to the second database using the psql
command:
psql -U postgres -f dcmms_merge.sql dcmms
If this procedure is repeated, the records that have been merged previously should be removed before merging again. This avoids PostgreSQL complaining of constraint violations (Uniqueness of primary keys).
Remove old files from c:\tmp
and
c:\tmp\ms_tmp

The DCMMS installer schedules a task that runs
the script c:\program
files\dcmms\script\recreate_tmp.bat
every day at 12:01.
The Schedule can be changed or deleted through the Windows Task Scheduler:
Select
-> .Choose Performance and Maintenance from the list.
Click on Scheduled Task. The task will most probably be called at1.
All data related to the DCMMS business processes should be checked, at least with some samples.
The following list is a preliminary list of checks that should be performed:
The data entry quality should be checked by comparing the workorder sheets against the contents of the database.
The database information should be verified with the customers that filed the complaints.
The recorded diameter and material of pipes should be checked against the GIS water network data, if available.
Caution | |
---|---|
A damaged DCMMS installation can be difficult to repair and may require a complete re-installation of the system. For this reason, a proper user privilege separation is of utmost importance. |
The user operating the DCMMS application on the server must not have any administrator rights assigned.
The PostgreSQL administrator and the postgres accounts should be guarded by good passwords (not "password", "1234567quot; or "") and these password should only be known to the administrators.
Caution | |
---|---|
When changing the password of the Windows user "postgres", the administrator has to re-enter the postgres password in the properties of the PostgreSQL Database Server 8.1 service. |
Database administration can be performed e.g. using pgAdmin which is included in the PostgreSQL installation. The SQL language can be used to perform those tasks that are not directly accessible through the pgAdmin GUI.
See the PostgreSQL documentation for detailed information regarding the PostgreSQL database and SQL commands.
Tip | |
---|---|
Experienced ORACLE administrators that are used to work with sqlplus may prefer the psql commandline environment over pgAdmin. |
Advanced analysis possibilites.
The script
script/create_pressurizedmain_analysis.sql
can
be used to calculate the number of repairs for each pressurizedmain.
To remove the result fields and the nearest() function from the
database, use the script
script/delete_pressurizedmain_analyis.sql
.
The pressure dependency of leaks can be proofed by showing that the repair frequency is higher in areas with higher network pressure.
To simplify the analysis, the topographic elevation will be used as an indicator of the network pressure. It is assumed that the lower areas of a distribution zone show higher static pressures.
The analysis can be performed by overlaying the elevation distribution of reported leaks with the elevation distribution of network nodes. Histograms are a suitable way to visualize these distributions.
The assignment of elevations to network nodes and leak repair locations can be done e.g. from spot elevations with ArcView's Geoprocessing Wizard or from a Digital Terrain Model (DTM). You should discard those node elevation that are higher than the maximum leak repair elevation or lower than the lowest leak repair elevation.
Once the elevations have been assigned, the R statistical analysis package can be used for the analysis. R is available from http://www.r-project.org/.
Note | |
---|---|
The following example assumes that the elevation information
is stored in the |
In R, load the "foreign" package by selecting
-> from the menu. This allows you to load DBF data.In the R Console, load your DBF files into the objects leak and maintenance:
leak <- read.dbf("c:\\leak.dbf") node <- read.dbf("c:\\node.dbf")
The summary
function can be used to
check if the import was successful:
summary(leak)
Filtering of data is possible with the following command:
filteredelevation <- node$Elevation[node$Elevation > 500 & node$Elevation > 1000]
The following commands allow to overlay the histograms:
hist(filteredelevation, col="yellow", main="", freq=FALSE, ylim=c(0, 0.03), xlab="Elevation in m", breaks=20) hist(leak$Elevation, border="red", col="red", density=30, main="", add=TRUE, freq=FALSE, breaks=20) legend(425,0.025,c("Maintenance Events", "Network Nodes"), merge=TRUE, fill=c("red", "yellow"), density=c(30, 100))
The created image can be saved in various formats.
If the histogram shows that the distribution of the leak repairs is shifted to the left compared to the distribution of the network nodes, the leak distribution is most probably pressure-dependent.
A collection of best practise procedures that help to administer DCMMS installations.
How GIS data is managed and reviewed in the case of NGWA.
NGWA's GIS data is kept in shapefile format, managed by the CVS version management system.
Figure 2.59, “NGWA GIS Data Review” outlines activities, roles and responsibilities of the GIS data review process. The process ensures that only quality-checked data is used in the DCMMS production system.
The DCMMS Manager has to check the lastest GIS data in the CVS using a DCMMS test installation. If necessary, the GIS operators have to correct errors (e.g. different field names used in a tiled set of shapefiles). Once the data has passed the quality control, the DCMMS has to mark the files in the CVS with the tag DCMMS.
Important | |
---|---|
The DCMMS manager should update each shapefile used in the DCMMS indidually: Update the shapefile on the test machine, update the indexes, view it in the application. Updating of all files at the same time bears the risk of not being able to identify the file that causes the problem. |
The DCMMS administrator is responsible for the CVS update script on the server. The script updates shapefile tilesets, shapefile indexes and the GIS data used in the DCMMS production system.
The following batch file illustrates the update on gisserver:
e: cd sandbox\dcmms\ngwa cvs update -dP -C -r DCMMS tile4ms lot_line_index.txt lot_line_index tile4ms gravitymain_index.txt gravitymain_index tile4ms pressurizedmain_index.txt pressurizedmain_index shptree ajlun\mapping\lot\lot_line.shp shptree ajlun\water\network\pressurizedmain.shp shptree ajlun\sewer\network\kufranja\gravitymain.shp shptree al_koura\mapping\lot\lot_line.shp shptree al_koura\water\network\pressurizedmain.shp shptree badia\mapping\lot\lot_line.shp shptree badia\water\network\pressurizedmain.shp shptree irbid\mapping\lot\lot_line.shp shptree irbid\water\network\pressurizedmain.shp shptree irbid\sewer\network\irbid\gravitymain.shp shptree irbid\sewer\network\dougrah\gravitymain.shp shptree jarash\mapping\lot\lot_line.shp shptree jarash\water\network\pressurizedmain.shp shptree jarash\sewer\network\gravitymain.shp shptree kinana\mapping\lot\lot_line.shp shptree kinana\water\network\pressurizedmain.shp shptree mafraq\mapping\lot\lot_line.shp shptree mafraq\water\network\pressurizedmain.shp shptree mafraq\sewer\network\mafraq\gravitymain.shp shptree ramtha\mapping\lot\lot_line.shp shptree ramtha\water\network\pressurizedmain.shp shptree ramtha\sewer\network\gravitymain.shp shptree shouna\mapping\lot\lot_line.shp shptree shouna\water\network\pressurizedmain.shp shptree ubaid\mapping\lot\lot_line.shp shptree ubaid\water\network\pressurizedmain.shp shptree ubaid\sewer\network\gravitymain.shp
The Windows Task Scheduler is used to run the update script every night.
New releases of DCMMS may use an updated data model. The following section describes two updating approaches.
If you are upgrading more than one minor number, please apply the individual updating instructions in the right sequence. However, if this includes multiple PostgreSQL or PostGIS updates, it should be sufficient to just perform the most current PostgreSQL and PostGIS updates.
Tip | |
---|---|
Whenever you're upgrading PostGIS or PostgreSQL, please also refer to the related upgrading information in the the PostGIS and PostgreSQL documentation respectively. |
Caution | |
---|---|
Before every update of DCMMS, you should backup your data. See Section 2.3.3.1, “Backup” for the details. |

One of the new features in 1.0.5 is the visual identification of duplicate workorders. You should add a new layer to show the area of interest for the pending workorders. This allows the visual identification of duplicate complaints. E.g. add the following to your map files before the first layer: |
# PendingWorkorders LAYER CONNECTIONTYPE postgis NAME PendingWorkorders maxscale 15000 TYPE POLYGON STATUS DEFAULT CONNECTION "dbname=dcmms user=dummy password=dummy host=localhost" DATA "areaofinterest from workorder using unique oid using SRID=-1" filter "status = 1" CLASS NAME 'PendingWorkorders' STYLE SYMBOL "aoihatch" SIZE 8 WIDTH 1 ANGLE 315 COLOR 255 150 150 OUTLINECOLOR 255 150 150 END END TOLERANCE 15 END # Layer
If you are not using a custom symbol file (not

Version 1.0.4 is a bug fix and maintenance release that brings several improvements to the DCMMS application.
See the "Upgrading" section in the PostGIS Manual for information how to upgrade to the latest PostGIS version.
You can use ActivePerl to run postgis_restore.pl. For example:
set PGUSER=postgres set PGPASSWORD=password set PGCLIENTENCODING=WINDOWS-1256 set PGPATH=c:\program files\postgresql\8.0 PATH=%PATH%;c:\program files\postgresql\8.0\bin pg_dump -Fc dcmms > dcmms.dump dropdb dcmms postgis_restore.pl "%PGPATH%\share\contrib\lwpostgis.sql" \ dcmms dcmms.dump > restore.log
There are several changes to the data model, see
script/update_dcmms_ddl.sql
for the details.
The new streamlined GIS data translation system requires one map
file per language. Existing map files and
include/dcmconfig.php
have to be adjusted manually.
See the default configuration files for an example how the new system
works.
The IdentifyPlugin configuration file is new and has to be adjusted where necessary (Section 2.2.3.1, “Identify Plug-Ins”).
User looking for improved performance should use PostGIS 1.0.0 or
better with the definitions in lwpostgis.sql
file.
As of PostgreSQL 8.0.2, this is not part of the PostgreSQL installer,
but a separate installer is available from the internet. Note that
there's a known bug with the shapefile loader in PostGIS 1.0.0. The
DCMMS installer will use lwpostgis.sql
instead of
postgis.sql
when it is found.
Version 1.0.3 is a bug-fix release that fixes a problem
in the update_dcmms_ddl.sql
(See bug #1098354
for the details). In addition it provides some documentation how the
Cygwin-based PostgreSQL database can be migrated to the native
Windows version.
There are two upgrade options from the Cygwin PostgreSQL version to the native Windows one: You can edit an SQL dump file of the database or you can dump only the contents of selected tables. While the first option might be quicker, the second one ensures that you also update to the latest PostGIS version. Following are some hints:
Dump your Cygwin PostgreSQL database as a SQL file. Make sure that all references to the fuzzystrmatch module are like the following: '$libdir/fuzzystrmatch'. All references to PostGIS should look like the following: '$libdir/libpostgis.dll'. All references to PostArabic should look like the following: '$libdir/libarabic.dll'.
The edits can be performed e.g. using sed.
Create the database structure from scratch e.g. using create_dcmms_ddl.sql. Dump only those tables you want to transfer. The dump procedure described in Section 2.3.3.3, “Merge DCMMS Databases” gives a good example how you can do this. AdministrativeArea, Village and Landmark should be loaded via the shapefile loader.
For the Windows installation of DCMMS the most notable change in version 1.0.2 is the use of the native Windows PostgreSQL version 8.0. The Windows release of PostgreSQL includes an updated version of pgAdmin III featuring backup and restore functions. For this reason, the backup and restore functionality has been removed from the DCMMS interface.
When updating to version 1.0.2, make sure that all PostGIS layers in your mapfiles have a dummy user and password entry in the connection line like in Example 2.1, “PostGIS Connection Example”. The password entry was previously omitted.
Make sure that you update your dcmconfig.php
as some functions might not work otherwise.
Please follow the steps below to update a Windows installation of DCMMS from version 1.0.0 to 1.0.1.
Remove Apache and install the latest version. This is optional.
Uninstall DCMMS Scripting by running
c:\program
files\php\uninstall-dcmms-scripting-4.3.5-2.exe
.
Install the new DCMMS Scripting version.
Install the new DCMMS version. The following components should be selected in the DCMMS installer:
DCMMS
Mapserver
Apache/PHP Config
Scheduled Cleanup
Update
Restart Apache or reboot the system.
Caution | |
---|---|
When you are upgrading from DCMMS 1.0.0 to 1.0.1 and the logon.php page is empty, make sure that you've installed the PEAR module "Log". |
The coded values in the standard DCMMS installation cover the needs of all DCMMS users. If your installation does not need some of those values, simply remove them from the respective tables in the database. You can use pgAdmin for this.
Caution | |
---|---|
When removing coded values, make sure that these have not been used during the data entry. Migrate those critical values to others first. |
Materials in DCMMS are simple records in the MaterialDomain
table of the dcmms database. Adding a
material is as simple as adding a new record. See Section 2.2.4, “Database Side Customization” for the details.
This section gives help to solve problems with the DCMMS installation.
The dcmms-info mailing list may provide
help to solve problems, either through the archives which are
available under
http://sourceforge.net/mailarchive/forum.php?forum_id=32901.
or by sending an email to

Verify that the Scheduled Task "at1" was removed. Delete if necessary.
Delete the Windows user "postgres", e.g. with the following command:
net user postgres /delete
Verify that the DCMMS folder was removed from the Start Menu.
Reboot.
If symbols like the hatching of in the area of interest symbol do not show transparent parts as expected, make sure that you use the following configuration line in the LAYER definition of your mapfiles:
TRANSPARENCY ALPHA
This applies especially when overlaying raster data with partially transparent symbols.
When encountering problems after loading shapefiles, use the DCMMS data model to double check that the required fields of all tables are in place.
The PostgreSQL timezone needs to be changed if DCMMS reports the error "Configuration error: PHP time != PostgreSQL time".
pgAdmin can be used to edit postgresql.conf
: Select -> -> from the menu.
Change the timezone value to e.g. GMT-2
Save the configuration: Select
-> from the menu.Reload the server configuration: Select
-> from the menu.Restart the PostgreSQL service.
Note | |
---|---|
You can check the timezone setting by the following SQL statement: select now() This time needs to equal the system time (as displayed e.g. in the task bar). |
Note | |
---|---|
The error message on the logon page contains the correct timezone setting. |
Important | |
---|---|
Timezone names in Windows and PostgreSQL are different. If your Windows timezone is GMT-3, you'll have to use the PostgreSQL timezone setting GMT+3. |
When running PostgreSQL 8.1 and creating login roles using pgAdmin, make sure to check the option "Inherits rights from parent roles". Otherwise the following error messages might occurr when logging on:
Warning: pg_query(): Query failed: ERROR: permission denied for relation causedomain in C:\dcmms\index.php on line 62
Warning: Your data model might be outdated. Please contact your administrator.
Starting with version 8.1.0, PostgreSQL is not creating the OID column by default any more.
Map files used with DCMMS up to version 1.0.5 may have implicitly used the OID column.
To fix the problem locate the layer with the problem. The layer name is mentioned in the error message. For example: Failed to draw layer named 'Landmark'.
Locate the layer in the map file. For example:
DATA "the_geom from landmarkview using SRID=-1"
Add the missing "using unique" statement. For the above example:
DATA "the_geom from landmarkview using unique id using SRID=-1"
Repeat this for all problematic layers
If newly inserted landmarks do not show up in the selection list,
most probably they have been digitized outside of the Village
or AdministrativeArea
boundaries. See Section 2.3.1, “GIS Data Loading” for further
information on quality control of Village
and
AdministrativeArea
.
When upgrading a PostgreSQL installation using upgrade.bat
, the PostGIS version might be downgraded if
PostGIS was first installed through the PostgreSQL installer and
later upgraded using the stand-alone installer.
Fix this by installing the latest PostGIS installation again.
If the application fails to connect to the database, check that the "PostgreSQL Database Server" service is up and running on the server. The Windows Services control panel can be reached for example by right-mouse clicking on the Apache Monitor symbol in the taskbar and selecting
from the context menu.Tip | |

Copy php_mapscript_46.dll
to c:\windows\php
and use depends.exe to
verify that all DLL dependencies are fullfilled. depends.exe is available e.g. with the
Windows XP Service Pack 2 Support Tools.
If map labels are not displayed properly (e.g. garbage diameters) and you're using tiled shapefiles, check that all your shapefiles have exactly the same table definition. Field name, type and order have to be exactly the same in all your shapefile tiles.
Suppose you have problems restoring a DCMMS
database and you are getting the following error message:

When trying to open a page, the following message appears on the server: Unknown(): Unable to load dynamic 'C:/Program Files/PHP/extensions\php_gettext.dll' - The specified module could not be found.
The following points may help to solve the problem:
Make sure that you've installed the zip distribution of PHP and not the installer version
Copy the file libintl-1.dll
from
c:\program files\php\dlls
to
c:\winnt\system32
or
c:\windows\system32

This also applies
to iconv.dll
- in this case, copy
iconv.dll
to
c:\windows\system32
or
c:\winnt\system32
.
The dll files
can be found in the folder dlls
of the
PHP distribution
See also Section 2.8.12, “FATAL ERROR: PHP extension 'MapScript' is not loaded”.
If you have a PHP error displayed on the page "Warning: Cannot modify header information - headers already sent by ". The solution of this error is changing the output_buffering variable to <B> on </B>.
Apache, PostgreSQL, PHP and some of the installers write log files that are often helpful when troubleshooting.
The level of verbosity of the server logs can often be specified in the server configuration files.
The following locations might contain important log files:
%TEMP%
- log files
of the DCMMS installer scripts
c:\program files\PostgreSQL\8.1\data\pg_log
- folder with
log file of the PostgreSQL server.
The windows system log files.
DCMMS requires a long maximum execution time for PHP scripts, MapLab requires a short one (30 seconds).
In order to ovecome this problem, it may be required to use two
different php.ini
files.
As MapLab is using the .phtml extension for the PHP files, this is
possible with the following directive in
httpd.conf
:
SetEnvIf Request_URI "\.phtml" PHPRC=c:/
Note that this directive has to be inserted after the SetEnvIf module is loaded.
Make sure that the DCMMS application is not indexed by htdig. This will lead to an endless loop and slow down your system.
The htdig package offers as search engine for websites. Please check wether you're running htdig before investigating further.
When upgrading from the Cygwin PostgreSQL version to the native
Windows version, it could happen that some fields are too short while
restoring because UNIX newlines (1 character) are converted
to Windows newlines (2 characters). In this case, the dcmms.dump.ascii
file generated by postgis_restore can be edited to adjust the
field definitions.
Note that dcmms.dump.ascii
has the same encoding
as the database (probably UTF-8).
