Hi,
i did not find anything in the "IBM Help" (maybe my search query was not optimal).
Is it possible to log the MQ Messages that a QMGR has received or send? If yes, how can i configure this?
Thanks for you help and sorry for my bad english.
Kind regards
Sebastian |

There's not a setting for this. There's also very seldom a genuine need to do this except for a kind of management nervousness that thinks it might help. Questions to ask are:
What use will the logged messages be put to?
How long will they be kept for?
What process will delete obsolete logs?
You do have statistics and monitoring options within the queue manager, showing details of volume and message flow. This might meet your needs.
If you actually want to log each and every message flowing through the queue manager, options open to you include:
- Don't bother. Monitor the health of the queue manager instead.
- Purchase a toole like Cressida's ReQuest which can read the transaction logs. Do not attempt to write your own application which does this
- Put proper logging in the sending / receiving applications
- Have the sending / receiving applications use COD/COA messages
- Use something like a mirrorq exit on all the local queues (note that you can't monitor sent messages with this method, but must install it on all the receiving ends)
Other solutions are probably possible, but they probably suck as much as these do.

thanks for your answer.
I will talk to our developers if they can implement something for more logging |

Another option is to use WMB (assuming you have it) to warehouse the messages to a database by routing the messages through a suitable message flow to achieve this.
Generally this is not required, providing the applications use persistent messages with proper syncpointing (ideally 2 phase commit) - they won't lose any. |

Another option, often discussed here, is to write SEND and RECEIVE channel exits that capture messages as they arrive/leave, and write them to tape or disk or whatever.
I'd suspect that there's an auditor lurking somewhere in the background, believing that this is a Soxley requirement.

That's even worse than mirrorq!

Or just wanting a lot of lovely but purposeless logs for Xmas.

Yes, on the worse-o-meter.

Nice new word Bruce. I know of Sarbannes Oxley or Sox. Soxley is a new one for me....

Depends how long you want to keep the copies and where.
Consider message duplication (a very simple program or WMB flow can do this).
MQSoftware have Statwatch which copies the first 4k of messages.
There are other options. You could just use MQ linear logging and keep the log files. |

And read them back how?

a) Exits are never a good idea
b) See my options above. Doing this is seldom a good idea

Don't Cressida make something that will do it? (plug for a mug? - only joking!  )
