This section describes the tasks you need to perform to prepare
your primary site and your remote site for disaster recovery using CICS® TS and CICS VR.
Planning for remote site disaster recovery
Because
the requirements and resources of every CICS VR user can differ, the remote site
disaster recovery plan of every user also differs. While no one plan works
for every user, there are a few common functions that need to be performed
in every plan. By performing these functions, you can use CICS VR to successfully
recover VSAM spheres updated by CICS applications, batch applications,
or both at the remote site.
The following topics are described:
- Using RCDS reports
- Preparing at the primary site
- Using CICS VR
at the remote site
- Sample recovery scenarios
- Using mirroring technology
- Using the log stream copy utility to copy your MVS™ log streams
- Using the RCDS utility to export your RCDS
- Using the RCDS utility to import your RCDS
- Finding more remote site recovery information
Note: The following steps assume that your remote site disaster recovery
plan restores and recovers only the VSAM spheres at the remote site when a
failure occurs at the primary site. If your current disaster recovery plan
uses a mirroring technology to keep the remote site information identical
to the primary site, see
Using mirroring technology.
