- Define and load VSAM spheres.
- Create DFSMShsm logical
backups and specify TAPE as the TARGET.
- Update the VSAM spheres with CICS® applications, batch applications,
or both.
- Perform LOGOFLOGS
SCAN.
- Create log stream copies of the MVS™ log streams that contain the log records.
- Perform RCDS
EXPORT.
- Create backups of the DFSMShsm control data sets and journal periodically.
To manually create CDS backups, first issue the DFSMShsm QUERY CDSVERSIONBACKUP command.
This displays the names of the sequential data sets used to backup the DFSMShsm CDS
and journal. Record these names. To backup the DFSMShsm CDS and journal to DASD, you
must pre-allocate the listed data sets. To backup the DFSMShsm CDS and journal to TAPE, these
data sets are dynamically created. Next, issue the DFSMShsm BACKVOL CDS command to backup
the DFSMShsm CDS.
- If you create copies of the DFSMShsm journal more often than you
backup the DFSMShsm CDS,
use the copied journal to update the CDS with the latest activity on the journal
at the remote site.
To backup the DFSMShsm journal, first stop DFSMShsm.
Then, run the ARCBJRNL utility.
- Send the following to the remote site:
- DFSMShsm logical
backups of the VSAM spheres.
- Log stream copies.
- Sequential data set that contains the exported RCDS.
- DFSMShsm CDS
sequential data set backups.
- DFSMShsm journal
backup.
At the remote site: - Stop DFSMShsm if
it is active.
- Mount the tapes with the DFSMShsm backups, log stream copies, and exported
RCDS.
- Perform RCDS
IMPORT.
- Catalog the log stream copies.
- Sort the DFSMShsm journal
backup by KEY using the EQUALS parameter.
- If DFSMSdss was
the data mover used to backup the DFSMShsm CDS:
- Restore the DFSMShsm CDS
from their backups.
- Export the restored data sets using the IDCAMS program.
- Use the ARCIMPRT utility to create the CDS at the remote site using the
exported CDS and sorted journal as input.
- Start DFSMShsm.
- Call the CICS VR
panel interface. Accept the default recovery values and specify QSAM copy as
the log stream type to create and submit a recovery job that restores the
VSAM spheres from their latest backup, then perform a forward recovery. CICS VR
can now query DFSMShsm for
the latest backups that exist for each VSAM sphere.
See z/OS® DFSMShsm Storage
Administration Guide for more information about DFSMShsm and the enhanced CDS recovery
function.
