I have an WMQ application that is using MQ Client to connect to a z/os queue manager. Because the way the app is functioning it is causing a high number channel connects and disconnects. The Application is running on AIX 5.2.
How can we approach or how can we reduce the number of connect and disconnects? Fully implementing WMQ on the application server is not an option at this time.
thanks, |

Really, the only way to do this is to rewrite (ie. improve) the client code to do one MQCONN and one MQOPEN and then do all of its work with that handle.
If your solution has been architected to call MQCONN-MQOPEN-MQPUT/MQGET-MQCLOSE-MQDISC for each message, well then you will want to revisit that approach to stop the frequest connects/disconnects.

Recode the application.
It should connect at start-up, do what it does for as long as it needs to do it, then disconnect. I would theorise it's been written as a single shot application that processes a single transaction on a single connection, giving you this high churn rate.
Failing that, you might be able to run it under some kind of application server solution that offers connection pooling. Lots of variables there...
