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
will only restore and recover 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.
