Hello,
I'm trying to use mirrorq API exit to copy some messages for accounting purposes. It works fine for messages registered by hand or using amqsputc. But, when I'm trying to inject some using third party adapter (TIBCO MQ Adapter in this case), messages are not copied over. I've tried to trace MQ activity, but cannot find any MQOPEN calls. System is AIX 5.3, MQ 5.3.12. Could someone help with this matter ? 
Regards,
Peter |

I bet TIBCO adapter is using a client connection.
There is a known issue with some versions of mirrorq copying messages from clients.
There was supposed to be an updated version that had a fix for this, that would be made available on the download site. But that may not have happened. See if you can solve this problem by redownloading the mirrorq package.
Alas, mirrorq is only sample code anyway, and so is not supported in any way by anyone.

I think the problem is when the application connects with a blank UserID or a mqm UserId. (In both cases it will be mqm if the MCAUser field is blank.)
The original Mirrorq code called a MQ function to exclude MQ API calls from mqm. (or something like that).

Thanks for your replies.
MQ Adapter from TIBCO can use either client or server mode. We
are using server. I'm using latest version of mirrorq, with update that
fixes if the same queue is opened multiple times without matching close
(as some adapters do). But still the same problem - messages from
MQ adapter are not duplicated. TIBCO connects MQ with userID "tibco",
and this user has all permissions granted.

Did you restart the queue manager after configuring mirrorq?

Yes, I did. Exit works fine for messages registered by for example
amqsput or amsqputc. But not for data registered by adapter, those are
passing through MQ without being copied to accounting queue.

Last time I looked, there were some environment variables that the code recognized that would cause it to output debug traces and otherwise alter behavior.
Yeah. It looks like you want to set MIRRORQ_LOG_PATH to a fully qualified file path, and then MIRRORQ_LOG_OPTIONS to the value 6.

Thanks for help. I've ran trace and got the following output:

This 2035 is very strange. Authorization for user for QM and queues is +all. Anyone got an idea what I missed here ?

Problem is fixed now. It was lack of permission for adapter user to
namelist object in queue manager. I've add those rights and it works
perfectly now.
Thanks for your support,
