Can someone tell me how to read the /var/mqm/log/<qmgr>/active/*LOG Logs ( S0000000.LOG ) They are data files. I want to see the messages in those files.
Thanks

These are active files, its used to Start the queue manager. and will be using by the queue manager.
I dont think so it will be in a human readable format...

There are very few good reasons why you'd want to do this. There's not too much they can tell you that you can't find out more easily from other sources.
IIRC Cressida produce a product that can read the files, but I could be wrong.
Again I wonder why you'd want to, and offer a friendly warning about doing so, especially on Windows. Unexpected file handles & locks on those files can make the queue manager confused.

dmpmqlog is the program to use, supplied in every MQ server installation. Instructions are in the System Administration Guide. |

Good point! 
I still question the need, and the fact that dmpmqlog requires the queue manager to be shut down can make it inconvientient.

Two needs come to mind:
1. curiousity.
2. absolute last place to look for lost data
For 1. above, create a new qmgr, some queues, put some messages, get some messages, alter an object, stop the qmgr, dump the log, enjoy.
For 2. above, a client (in near-disaster frame of mind) asked me if the log was a good place to try to recover lost data - not lost messages. Their data was lost due to disk failure. They had no file backup (it was on the same disk), no source data, no hardcopy doc, nothing.

Another need to log in the Active logs was to see the exact message sent to the queue, Instead of trying to read or dump from the queue.
As per my understanding once the message is put on the queue, it doesn't need to stay on the log any more.
These Active logs are data files so we should not be reading them with regular unix cat commands.But we can still look at them using cat and can see messages besides it shows junk characters in there.
Any other way to get the dump of exact message in xml format that was put in queue without removing it from the queue? |

Browse. Use amqsbcg or any MQI app that calls MQGET-with-browse. |

Nope. Nope. Nope.
Please, oh please, read the System Admin Guide section on Recovery and Restart.

Please, if you need to audit messages, build auditing into the application, or flows, or mirrorq, or anywhere but this. You'll also find it so cumbersome like this, as not only do you have to stop the queue manager to do this, you'll need to manually avoid duplicates.

Yes it does.

Any number, including but not limited to the methods I list above.

I'm really quite certain that RFHUtil(c) is IH03.
