The configuration file contains data source definitions, CA IDMS system access path information, global option settings, and JDBC server options, corresponding to the information maintained in the registry on the Windows platform. The file is formatted as a text file with sections containing lists of key‑value pair parameters, similar to a Windows .ini file. You must edit this file manually for z/OS.
The default file name is caidms.cfg. CA IDMS Server first looks for this file in the current directory. If it is not there, CA IDMS Server looks in the installation directory. You can use the IDMS_CFG_PATH environment variable to specify a different name or directory.
For example, to locate the caidms.cfg file in the application directory /idmsdir:
set IDMS_CFG_PATH=/idmsdir/ export IDMS_CFG_PATH
For performance reasons, the configuration file is cached in memory the first time the libidmsutil.so DLL is loaded into a process. Therefore, changes to the configuration file may not take effect for a running process until the process is quiesced and restarted. For the JDBC Server, use the suspend and resume commands documented in the chapter on "Using the Client on z/OS." For testing and other implementations where performance is not critical, the cached configuration file can be refreshed more frequently or caching can be turned off completely using the IDMS_CFG_RELOAD environment variable, or with the CacheConfig option. For more information, see the appendix "Configuration File Information."
