Most IBM software allows you to modify the default behavior of a product by implementing exits.

Exits in WMQ are tightly architected and well defined. What this means that your exit code must enter and exit your exit code via well-defined mechanisms. Writing exits is a specialized activity.

An example: Communication channels have several exit points. The send exit (if you have coded one AND installed the code in the exits folder) will be executed just before a message segment is sent across the channel. In this exit, you have full access to the message. If you have a requirement to do something just before a message segment is sent across the channel (like write an image of the message to a file), this exit could be a place to take such action.

If your organization has implemented exits, the exits folder will contain the executables for these exits.

This is a Windows thing, not really related to WMQ. Before you fiddle with Registry settings (or install software that does), back up the registry.

1. Click Start/Run
2. regedit
3. click registry
4. click export

Now you have an image of the registry before you make changes.

You can create a batch file and run it nighly. The command would be:
Code:
regedit /ea QueueManager.reg HKLM\SOFTWARE\IBM\MQSeries\CurrentVersion\Configuration\QueueManager

There's a good IBM Redbook 'Backup and Recovery' that will help you set up a strategy for backing up important WMQ things. http://www.redbooks.ibm.com/abstracts/sg245222.html

Things to back up:
- your object definitions
- messages, if any, left in queues at shutdown

Make sure you have adequate backup and recovery procedures that have been tested, BEFORE you upgrade. You should be doing regular backups for business continuation (disaster recovery) purposes.
