Step 2: Allocate the HFS

An HFS must be established to store the CA IDMS Database Server Option executables and configuration files. CA IDMS Server requires approximately 2 MB in the HFS during the installation. Log files created at runtime may require additional space, and can be allocated in a separate HFS devoted to temporary files.

You can install CA IDMS Server into an existing HFS if space is available, or you can set up a new HFS specifically for CA IDMS Server. Only users with OMVS superuser authority can allocate and mount a new HFS. If you decide to set up a new HFS, you can also establish a new OMVS UID and GID to serve as the owner and administrator of the CA IDMS Server HFS files. Consult with your site Security Administrator for assistance in performing this step.
