Starting after an abnormal termination

WebSphere MQ automatically detects whether restart follows a normal shutdown or an abnormal termination.

Starting a queue manager after it ends abnormally is different from starting it after the STOP QMGR command has been issued. After STOP QMGR, the system finishes its work in an orderly way and takes a termination checkpoint before stopping. When you restart the queue manager, it uses information from the system checkpoint and recovery log to determine the system status at shutdown.

However, if the queue manager ends abnormally, it terminates without being able to finish its work or take a termination checkpoint. When you restart a queue manager after an abend, it refreshes its knowledge of its status at termination using information in the log, and notifies you of the status of various tasks. Normally, the restart process resolves all inconsistent states. But, in some cases, take specific steps to resolve inconsistencies.
