The MQ logs are needed for various Servers. This is needed to track message movement between servers.
Have chked the path C:/Program Files/IBM/Websphere MQ/log/qmgrname/active/...
But could not find any recent logs.
Wht is that missing |

| Please explain further why you need these logs, and why you are looking in that directory for them. |

No they are not.

The format of the logs so you can read them? The logs are in a propreitory format which IBM doesn't publish, and can change (they did v5.3->v6).
As a side note, Windows queue managers get annoyed if anything else is acceessing their logs, and do fall over as a result.

What, precisely, do you mean by recent logs? If using circular logs you will see S0000000.LOG to Snnnnnnn.LOG depending on how many were specified, and the content will be overwritten as the logs wrap (look at the time/date stamp on the log for the last 'touch'). If using linear logs you will see S0000000.LOG to Snnnnnnn.LOG incrementing as new logs are formatted and written.
If you want to track message movement between servers use a commercial product (if there is one out there) or use application journalling. There is plenty of discussion on the boards about the utility of it, and about finding specific messages within logs - next to impossible I'd say if you're using circular logs.
EDIT: And as my worthy master points out - don't!

No they're not, as exerk points out circular logs are impossible to use for this and as I pointed out even linear logs are not in a published format. You really don't want the pain of digging through them.

I'll leave a passing Cressida person to discuss if any of their product set can be used for this. I'd go with application logging, for reasons endlessly discussed on the forum.

MQLogs are not at all suited to track traffic between qmgrs. These logs will only hold information for persistent messages. All non persistent traffic is not logged as the priority here is speed. Some non persistent messages do not even show up in queue MQI statistics as the handoff can be done in memory from the putting program to the getting application...
What you really want to do is define the reason for the requirement, verify that the traffic conforms to the reason and look at application logging for this type of requirement.
Have fun

the issue here is that, after last week when there was a reboot of the server; since then there hasn't been a single log created. i need to those logs to be available for verification purpose to check if the transaction has happened properly or not.
How can I find them? is there any option which has disabled the creation of the log files? |

Not if your queue manager is running! If you have not seen any new logs created the probability (certainty in fact) is that you are using circular logging, so check the last access time/date of your logs - but do not try looking in them - and please do heed the warning of my Venerable Master:

Do you mean that I should not open the log files.... just chk the date of their creation.... |

Then you're using non-persistent messages, or your queue manager isn't running, or you're looking in the wrong directory.
You still shouldn't be using these log files for any user purpose. It's at best pointless and at worst dangerous.

If you are looking for evidence of specific transaction activity, why not check some statistics inside MQ? Such as last put/get dates & times, channel activity, and so forth.
I think we are not clear about what it is you are trying to prove to your customer....? |
