I've deployed our message flows and message sets that we have been using on a Windows broker to an AIX broker (V5, CSD4) that we have set up, but none of the flows are working. When I put a trace node after the MQInput node, it shows that the MRM is empty, and what follows are lots of errors in the user trace because no XML elements could be accessed from the input XML message.
The MQMD is there, but no MRM content. The bar files are identical to those deployed on Windows. The "empty" message is being processed by nodes downstream, as I can see that a database lookup from a Compute node has worked OK.
Why would the MRM be empty? The flows and message sets deployed successfully. Is there something fundamentally different in deploying to AIX that I have overlooked?
Thanks

Hi,
Unfortunately there isnt enough information here to diagnose your problem. You say that your flow generates errors, could you post what these errors are.

Shutdown and restart the message broker. If the problem continues to occur, then restart the system. If the problem still continues to occur contact your IBM support center providing system trace files where possible.
===============================================
Even if I take out this node which attempts to validate the incoming XML, it fails on the next node in trying to access an XML element - probably because the MRM is empty
The Trace node for AIX produces this

Hi,
Your flow is receiving a BIP5347E exception from the MRM resource manager. This is usually thrown when the MRM cannot access the broker database to retrieve its messageSet. On the AIX platform, by default there are only 10 shared memory connections allows from a process to DB2. It is likely that you are hitting this limit and this is why you get the BIP5347E exception.
The following line http://www.mqseries.net/phpBB2/viewtopic.php?t=20644 will tell you how to resolve this.
Hope this helps.

Thanks Craig. My AIX login does not appear to have access to stop DB2. I will get the DBA to do this work tomorrow morning and will post a response.
