Steps in the process of recovery

The process of recovery includes two major tasks: planning what you intend to do for recovery before a problem occurs and reacting to a problem after it has occurred to fix the problem.

The task of planning for IMS recovery can be further refined:

Set up logging
Establish checkpoints
Make backup copies
Create procedures and assign responsibilities

The task of reacting can also be further refined:

Notice error
Shut down IMS (only if necessary) — can be a full or partial shutdown
Diagnose and fix (or possibly bypass) error
Use recovery utilities and services (if necessary) — can be run online or offline
Restart IMS (or the now fixed part of IMS)

Of course, real recovery is rarely as straightforward as these two lists suggest.
