Input and output for the Freespace Reclaim function

The INDEXBLD command in the HFPSYSIN DD control statement invokes the Freespace Reclaim function.

The Build Index function, the Resync function, and the Freespace Reclaim function use the INDEXBLD command to start the Build Index process. During the Build Index process, FPA builds, synchronizes, or reclaims space in secondary index databases. To determine which task to perform, FPA evaluates the IDXPROC keyword on the INDEXBLD command as follows:
  • When IDXPROC=BUILD, FPA starts the Build Index function. During the job, FPA scans one or more DEDB areas and builds one or more secondary index databases.
  • When IDXPROC=RESYNC, FPA starts the Resync function. During the job, FPA scans one or more DEDB areas and secondary index databases and synchronizes secondary index databases.
  • When IDXPROC=FS_RECLAIM, FPA starts the Freespace Reclaim function. During the job, FPA reclaims the CIs in secondary index database data sets.

The following figure shows the input and the output for the Freespace Reclaim function.
