Handling a destroyed or damaged checkpoint/restart data set

The checkpoint/restart data set can be destroyed (possibly from a hardware problem or from being deleted) or damaged (possibly by an I/O error). The procedure to use depends on whether an application program uses IMS and, if it does use IMS, whether the checkpoint records were written to the IMS log.
