Although CA CSM supports both non-SMS and SMS allocation environments, we recommend using only SMS for mount point management allocations and software installation temporary allocations.
Business Value:
CA CSM dynamically allocates temporary files during task initialization and GIMUNZIP processing for software installations. It also dynamically allocates new file systems as needed to store the product and maintenance files that are downloaded from the CA Support Online website. All of these allocations are performed based on the configuration settings in the CA CSM web-based interface (Settings tab, User Settings). Setting these allocations up under SMS eliminates the need for someone to actively manage the CA CSM Settings based on individual volume utilization.
SMS also helps ensure optimal space utilization and to verify that the appropriate backup and migration rules are used for these data sets.
Additional Considerations:
The initial settings for the file system allocations are specified during the installation process, and can be easily modified in the CA CSM web-based interface (the Settings tab, System Settings).
The allocation settings for the temporary data sets must be set after the installation is complete and the CA CSM web-based interface is accessible. The interface allows for a system setting and a user-specific setting for these allocations. The user setting will override the system settings when they are populated. The system settings should be set by the first user who accesses the application. Each individual user can set their own user settings as needed for their environment. User settings for these parameters are only recommended if the security environment dictates different settings for each CA CSM user.
