Abnormal termination

An abnormal termination can leave data in an inconsistent state, for example:

• A unit of recovery has been interrupted before reaching a point of consistency.

• Committed data has not been written to page sets.

• Uncommitted data has been written to page sets.

• An application program has been interrupted between phase 1 and phase 2 of the commit process, leaving the unit of recovery in doubt.

WebSphere MQ resolves any data inconsistencies arising from abnormal termination during restart and recovery.
