Running the disaster recovery preparation JCL

After the disaster recovery preparation job is built, you must run it on a regular basis to ensure the availability of recovery assets that are needed for disaster recovery at the remote site.

1. Delete old JCL and control cards associated with the system from the recovery PDS.
2. Complete the following processing steps:
   1. Validate the existence of an offloaded System Level Backup. The DR profile indicates whether a local or remote copy is being used for DR.
   2. Copy archive logs, image copy data sets, and change accumulation data sets for disaster recovery dependent on user options.
   3. Create a copy of the RECON data set and condition it to reflect the availability of archive logs, image copies and change accumulation data sets at the remote site.
   4. Save a copy of the conditioned RECON into the recovery PDS.
   5. Save the IMS Recovery Expert repository data into the recovery PDS.
   6. Create control cards needed for recovery.
   7. Generate a list of tapes to be taken to the disaster recovery site.
   The following outputs are generated as a result of this step:

   • BSYOPTN: List of all the profile options.
   • BSYREPT: Report of tapes that should be transferred to the remote site. These include the System Level Backup tapes, tapes of copies of recovery assets (archive logs, change accumulation data sets, image copy data sets) and the name and VOLSER of the recovery PDS.
   • BSYERROR: Any error messages and progress messages that are produced.
3. Generate JCL that is needed for the recovery of the system at the disaster recovery site. The disaster recovery preparation job must complete with RC=0.
