Maintaining the Database - APCIJRDR

Job APCIJRDR performs the following database maintenance functions:

• It saves data through IDCAMS REPRO, deletes and defines the VSAM clusters and reloads the saved data through IDCAMS REPRO.
• For each VSAM cluster, a JCL &-variable is used and is set to 1.That is, the reload for this cluster should be processed. If the reload should not be processed for a cluster, the variable must be set to 0 (or any value other than 1).
• The saved sequential data sets are not deleted. But if the reload job runs again, the previously saved data sets are deleted, if they still exist.

The job JCL for APCIJRDR is shown following:
