The following scenario uses change accumulation data sets instead
of log stream copies to perform forward recovery at the remote recovery site.
- Define and load VSAM spheres.
- 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.
- Update the VSAM spheres with CICS applications, batch applications,
or both.
- Perform LOGOFLOGS
SCAN.
- Run change accumulation jobs that consolidates log records for all of
the VSAM spheres you wish to recover at the remote site.
- Perform RCDS
EXPORT and specify the CA and BACKUP keywords on the RCDS EXPORT command.
- 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: - Catalog the DFSMSdss logical
copies, change accumulation data sets, and sequential data set that contains
the exported RCDS.
- Perform RCDS
IMPORT.
- 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.
