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.
