Use the log for recovery

We can use information from the logs to help you recover from failures.

• A damaged data object
• A power loss in the system
• A communications failure

This section looks at how the logs are used to recover from these problems.

• Recovering from power loss or communications failures
  IBM MQ can recover from both communications failures and loss of power. It can also sometimes recover from other types of problem, such as inadvertent deletion of a file.
• Recovering damaged objects
  There are ways in which an IBM MQ object can become unusable, for example because of inadvertent damage. We must then recover either your complete system or some part of it. The action required depends on when the damage is detected, whether the log method selected supports media recovery, and which objects are damaged.
