This tutorial shows how disaster recovery could be accomplished using backup resources like image copies, change accumulation data sets and, in some cases, the archived log data sets. There were three IMS Base and one IMS Tools Disaster Recovery solutions discussed, with examples showing several types of timestamp recovery and full database recovery. Each solution in this tutorial requires a certain amount of RECON conditioning.
In Part 3, you will learn how the IMS Tools product, IMS Recovery Expert, can automate many of the procedures, including the conditioning of the RECON data set. The IMS Recovery Expert product introduces the recovery resource called System Level Backup (SLB), which is used for disaster and local application recovery, significantly reducing the number of image copies needed at the production and remote sites.
