Restart process using the reorganization job JCL

Follow these steps to use the RESTART command in place of the REORG command in reorganization JCL:

  1. Use the existing JCL that was used for the reorganization (PGM=DFSRRC00,PARM='ULU,DFSURGL0, dbdName') with the following modifications:
    1. Retain the AMSOUT data set that was created during the reorganization job.
    2. Retain the IMS libraries (RECON, RESLIB, IMS, and so on) that were used in the reorganization job. If you made DBD changes, you must specify the former IMS DBDLIB. If you do not, the restart step fails.

    3. Remove all DD statements for the databases and image copy data sets.

      Warning

      The Online Reorg function and the Reorg function always require exclusive control during the data set name swapping phase. If you attempt a multiple step JCL allocation, exclusive control is lost and the database becomes unavailable.

  2. Remove the REORG command and all keywords from the PLUSIN control statement data set. Include the RESTART command in the PLUSIN control statement data set.If the database is a HALDB, the AMSOUT data set is a PDS, and selected partitions are selected, specify the partition name provided in message BMC180221I in the PART() keyword for the restart command.
