DFSMSdss logical copies and change accumulation data sets, no log stream copies - at the primary site:

The following scenario uses change accumulation data sets instead of log stream copies to perform forward recovery at the remote recovery site.

  1. Define and load VSAM spheres.
  2. Create DFSMSdss logical copies of the VSAM spheres. Be sure the copy jobs include the CICSVRBACKUP and RENAMEU(**,CICSVR.**) keywords and the CICS® VR address space is active when the jobs are submitted.
  3. Update the VSAM spheres with CICS applications, batch applications, or both.
  4. Perform LOGOFLOGS SCAN.
  5. Run change accumulation jobs that consolidates log records for all of the VSAM spheres you want to recover at the remote site.
  6. Perform RCDS EXPORT and specify the CA and BACKUP keywords on the RCDS EXPORT command.
  7. Send the following information to the remote site:
    • DFSMSdss logical copies
    • Change accumulation data sets
    • Sequential data set that contains the exported RCDS
At the remote site:
  1. Catalog the DFSMSdss logical copies, change accumulation data sets, and sequential data set that contains the exported RCDS.
  2. Perform RCDS IMPORT.
  3. Call the CICS VR panel interface and select the appropriate DFSMSdss logical copy from the VSAM sphere parameters secondary window. Specify MVS logger log stream as log stream type, the log streams do not have to exist at the remote site if the change accumulation data sets cover the entire recovery interval. Submit the recovery job that CICS VR creates. The job restores the VSAM spheres from their latest backup and perform forward recovery.
