Right now only RPM packages for GNU/Linux on i386-based CPUs are available.

Quickstart and Installing Webservices ------------------------------------- 1. Setup your environment The DGEE needs some environment variables set for it to find its resources, and to help this an env script is provided that should be sourced as required. If you use the DGEE supplied commands (dgadmin, dgeestart, csdgmx, dginstallws, dgremovews etc) to administer the system then the environment will not need setting manually. However if you need to change the runtime configuration file at any time then the environment will need setting. See the FAQ for further details. If you want to sent the environment perminantly for a user then the env script should be sourced by the .profile of the dgee 'user'. By default the DGEE runs as the nobody user which does not have a home directory, starting the dgee as root will see it switching to the configured user (nobody unless otherwise configured). So before running as root, execute the command: shell> . /usr/local/share/dgee/dgeeenv.sh If you're running the DGEE as another user, then edit that users ~/.bash_profile or ~/.profile depending on which you use and add the following line: . /usr/local/share/dgee/dgeeenv.sh (You'll have to log out and back in again as this user for the change to take effect) 2. Checking the System Configuration is correct Run the command dgeediagnose. This will check and report on may configuration issues that may affect the running of the DGEE. 3. Starting DGEE Run the command dgeestart (See the README for further information) 4. Configure Apache Add the following to your apache httpd.conf at the appropriate locations (the apache src directory contains an example httpd.conf): LoadModule dgee_module /usr/local/libexec/mod_dgee.so AddModule mod_dgee.c include /usr/local/etc/mod_dgee.conf # Optional 'directory' based DGEE association # allows http://url/dgee/test in addition to the default # http://url/test.dgmx # <Location /dgee> include /usr/local/etc/mod_dgee.conf </Location> Apache needs to run as either the user who started the DGEE or the DGEE needs to run as the Apache user. The following settings in httpd.conf file are suggested: User nobody Group nobody or, if these are not appropriate and you are building the DGEE yourself, then you may use the --with-username and --with-usergroup configure options (see ./configure --help for details). If you did not build mod_dgee.so yourself then you will need to copy the precompiled version from src/apache/precompiled/mod_dgee.so to /usr/local/libexec/mod_dgee.so (See INSTALL for details on Apache2). 5. Start Apache Start apache in the usual way 6. You may now install a webservice cd examples make This will create wstest.dll, state.dll and math.dll Generate a dgmx files for each of these webservices: csdgmx wstest.dll csdgmx state.dll csdgmx math.dll Now install the webservice into the dgee by running dgeeinstallws script: dgeeinstallws wstest dgeeinstallws state dgeeinstallws math (Or you can copy the dll files directly into /usr/local/var/dgee/data and the dgmx files into /usr/local/var/dgee/index - make sure the ownership on the directory and files is correct). You can now view the web service documentation for this webservice by pointing your browser at: http://my.local.apache.webserver/wstest.dgmx http://my.local.apache.webserver/state.dgmx http://my.local.apache.webserver/math.dgmx If you want to see the documentation in XML form, use the following: http://my.local.apache.webserver/wstest.dgmx?xml XML-RPC access to the webservice is enabled by POSTing your XML-RPC request to http://my.local.apache.webserver/wstest.dgmx The perl directory contains a simple XMLRPC test client. It requires XMLRPC::Lite which is part of SOAP::Lite. Notes: ------ Shutting down the DGEE before Apache will leave Apache hanging onto system IPC resources. This can be cleaned up by stopping Apache and running dgeestop again. Please see the README and INSTALL files and examples/readme for further information. Use examples/wstest.cs as a guide to writing your own webservices. If you're really Interested... ------------------------------ Investigate the following administrative commands: dgadmin pl # DGEE Process List dgadmin sl # DGEE Service List You can enter these commands interactively by typeing dgadmin directly. Type help to get a full list of commands available. (dgadmin is an alias for goldwater, using 'goldwater' will produce the same results). Chris Smith - 26/03/2003
