Using mirroring technology

The disaster recovery steps assume that you only use the remote site portion of the plan when a failure occurs at the primary site.

While this might be acceptable for many installations, the amount of time required to fully restore and recover the VSAM spheres at the remote site might not be acceptable for all installations.

For this reason, some installations might be constantly updating their remote site to reflect the activity at the primary site. This can be performed in a variety of ways using some version of mirroring technology. If you have this technology implemented at your installation, the amount of time required to recover VSAM spheres at the remote site compared with the disaster recovery method previously presented is significantly less. However, even though the disaster recovery plan is vastly different, the items CICS® VR requires for recovery remain the same. Below is a list of the minimum items required by CICS VR to use the CICS VR panel interface for recovery at the remote recovery site. Be sure your plan includes the following items:
