Hi all,
Running the dmpmqlog command, I can retrieve lots of information, but I would like to know what are the different fields present in the below message :

I've already searched in various MQ documents, but can't find the message structure of the data part ... I can see date and time, but what about persistence, ...

Another thing that would help me : where can I find the LSN start and end of a particular logfile ?
Having circular logfiles, is there a way to make dmpmqlog analyze all the logfiles ?

| As far as I know the structures of the various MQ log records are not documented anywhere. However it is possible to work through some dumped log records representing queue activity and decipher them. Similarly '...\log\QMNAME\amqhcltl.lfh' can be analysed to find information about the active log files, including LSN info. |

And you're probably better off doing whatever you're trying to do some other way, that doesn't involve understanding the log files.
Like using performance events, or API exits, or any number of other things.
