to view all websphere MQ messages in JMS call

I use JMS (Java Message Service API) in my java application to work with queues/topics residing on websphere MQ. I am looking for a tool/support pac which can show me all MQ Messages being called e.g. when I do queueConnection开发者_C百科Factory.createConnection(), it would have resulted into MQCONN/MQCONNX call, so I need to see what excatly is being passed. So basically during my entire JMS based interaction, I want to see all MQ messages which are being passed to. Is it possible?

if you are using websphere, you can turn on tracing by going to WAS console and tracing service to enable jms logging.

Trace tells you what APIs are being called. To a good extent trace helps. But beyond that call IBM help.

If you are using JMS MQ client mode connection it is possible to run send/receive exits on the MQ SVRCONN channel to log the client MQI and message flows. The free IBM SupportPac MA0Z has this capability. This technique is not possible with a binding mode connection because there is no MQ channel involved.
