Hello Everyone,
we have observed that one of the queue got damaged which had so many messages in it.
Could you please tell us the way to get the messages back to same queue?
Thanks,
Reddy. |

If you were using Linear logging, then you can recover that object. If not, you cannot recover those msgs (which is the reason to use linear logging if you have such a requirement). Were you using linear logging?
It is indicated in your qm.ini file. |

We are using circular logging but all are the persistent messages which would be storing in the filesystem.
Is there anyway to recover them?
Thanks,
Reddy. |

Looks like you just lost them. This is why linear logging exists. So you can recover your queue. MQ tells you the object is damaged... That can / may mean that you have a truncated transaction info in the log...
Typically handled by deleting the object and recreating it...
If you can still attach to the queue try saving all its messages to file...
Have fun

WMQ's transaction logs are not intended for application-level message data recovery.
Circular log segments are overwritten when they no longer active (containing units-of-work in-flight).
Linear (transaction) logs may be used to recover objects and messages with the rcrmqobj control command IF the object images were recorded to the logs with the rcdmqimg control command.

Yes, and no.
IBM does not provide a utility to scan through your logs looking for specific messages. Other vendors offer these. Search here and google.
The most frequent cause of object corruption begins with a system admin changing rwx bits in the WMQ filesystem.

If the messages are important for your application and system, better have linear logging for mq qmgr, which additionally require administering/managing of logs for media and restart recovery.
