Recovering from IMS-related failures

When you work in a Db2-IMS environment and problems occur, you can recover from those problems.

Symptoms

Problems that occur in a Db2-IMS environment can result in a variety of symptoms:

An IMS wait, loop, or abend is accompanied by a Db2 message that goes to the IMS console. This symptom indicates an IMS control region failure.
When IMS connects to Db2, Db2 detects one or more units of recovery that are indoubt.
When IMS connects to Db2, Db2 detects that it has committed one or more units of recovery that IMS indicates should be rolled back.
Messages are issued to the IMS master terminal, to the logical terminal, or both to indicate that some sort of IMS or Db2 abend has occurred.

Db2 can be used in an XRF (Extended Recovery Facility) recovery environment with IMS.

To resolve IMS-related problems, follow the appropriate procedure.
