Gentlmen the problem I have is backing up messages. I am having problems with 2192 page set full when to many messages are being backed up.
Currently I hold the backup messages in the queue and run a batch job to copy to a GDG and then delete when complete. Does anyone have any other process?

does "backup" means you hold a copy of the messages or do your queues fill up because the application is slow or because messages are collected and processed at a later time?
do you look for a inflight solution or for a long term solution?

What we do is store a copy of each message for client recovery puposes.

then backup more frequent for short term, for long term increase size and number of pagesets, split queues over pagesets and backup less frequent

Sounds like my shop... Buy more DASD and expand the pageset or write the bkp messgaes to someplace other them MQSeries.

And remember MQ is not a DB. The messages should be passthrough only!  |

| I would definitely recommend not using WMQ as your backup scheme, due to a thousand reasons discussed before (read carefully about WMQ logging process, and you'll know what I mean). Best way, IMO, would be to backup at the application level using some db or file or other. Just don't forget to code receiving application so that it is able to handle duplicates. |

Or at least, add a process that reads this queue, and dumps messages into a database, and then a process to read from the database and replay a message.

Sorry for the time between response, but was on vacation.
First thanks for the input, it looks like we are going to go with a db solution.
