Test Various PDS compress Functions (IVP06CMP)

CA Disk provides a PDS management facility that includes PDS reports and a PDS compression utility. Run the PDS reports using the standard CA Disk report procedure to include:

• A PDS Status Report which includes the data set and directory statistics
• A PDS Member Report that is a 12-up listing of the member names that reside in the PDS

Run the compression utility explicitly or in a scan mode. The scan mode evaluates the status of a PDS to determine whether to compress the data set. You specify certain threshold values that the evaluation module uses to make its determination.

The JCL runs the compress function in two steps:

1. Compresses the PDS leaving free space.
2. Compresses the PDS without free space.
