Defining cache storage file systems

This section provides an overview of what you need to do to define cache storage file systems for an instance. For details about defining cache storage file systems, see Modify the ARS.CACHE file.

Each instance must use different cache storage file systems. Before using cache storage file systems, you need to configure physical and logical storage, set the correct file system permissions, modify the ars.ini file to identify the cache storage configuration file that is used by the instance, and create a cache storage configuration file for the instance. The cache storage configuration file lists the cache storage file systems on which Content Manager OnDemand will maintain the documents that are stored into the instance.

When you start an instance, Content Manager OnDemand reads the ars.ini file for information used to initialize the instance. The SRVR_SM_CFG parameter in the ars.ini file identifies the cache storage configuration file that is used by the instance. (Each instance defined in the ars.ini file has its own SRVR_SM_CFG parameter, which must identify a unique cache storage configuration file.)

By default, the default instance identifies a cache storage configuration file named ars.cache. If you plan to run more than one instance, make a unique copy of the ars.cache file for each additional instance. When you install the Content Manager OnDemand software on the server, the ars.cache file is copied to the Content Manager OnDemand configuration file directory. To create a new cache storage configuration file, log on as the super user or as any user set up with appropriate permissions. Make a copy of the ars.cache file. For example, to create a cache storage configuration file for the instance named TEST, copy the ars.cache file to ars.test.cache. Then edit the cache storage configuration file with a standard text editor. Add one line to the file for each cache storage file system that you want the instance to use.

Modify the ars.ini file to identify the cache storage configuration file that you created for the instance. For example, if you created a cache storage configuration file named ars.test.cache for the instance named TEST, locate the [@SRV@_TEST] section in the ars.ini file and change the SRVR_SM_CFG parameter to identify the cache storage configuration file: SRVR_SM_CFG=/usr/lpp/ars/V10R5M0/config/ars.test.cache
