How to: Reallocate PDS files

If the persistent data store files fill up or become corrupted, new historical data cannot be collected. To correct this problem, the data sets must be reallocated.

Before you begin

Important: The content in this section was created for and applies to the original persistent data store, referred to as PDS V1. A new PDS version (referred to as PDS V2) now exists. PDS V1 will eventually be deprecated.
The started task for the monitoring server or monitoring agent collecting the data must be stopped when you perform this procedure. Schedule the procedure for a time when the server or agent is scheduled to be down or can be recycled.

About this task

To reallocate the files that store historical data, you delete the files and then reallocate the data sets.


  1. Delete the persistent data store files using the RKANSAMU(KppDELJB) job.
    Keep the Delete statements for the data sets you want to delete. Comment out or delete the Delete statements for any data sets you want to keep.
  2. Submit the composite KCIJPALO job to reallocate the files for multiple products, or the stand-alone KppJPALP job for a specific product.
    The stand-alone jobs are created in the WKANSAMU data set after the $PARSE (or $PARSESV ) job is run.
