Making sure that messages are not lost (logging)

 

WebSphere MQ records all significant changes to the data controlled by the queue manager in a recovery log.

This includes creating and deleting objects, persistent message updates, transaction states, changes to object attributes, and channel activities. The log contains the information we need to recover all updates to message queues by:

• Keeping records of queue manager changes

• Keeping records of queue updates for use by the restart process

• Enabling you to restore data after a hardware or software failure

• What logs look like
  

• Types of logging
