Test Idle Space Release Function (IVP03ISR)

If data sets are over-allocated and wasting space, CA Disk provides a flexible and convenient means to free this space. You can establish thresholds which allow extra space but, if exceeded, the unused space is released.

This JCL has the following steps:

  1. Releases IVP data sets to 50 percent used threshold.
  2. Releases IVP data sets to 100 percent used.
  3. Converts cylinder-allocated non-VSAM to tracks.
  4. Converts secondary allocation of non-VSAM to 50 percent of the primary.
