MQSeries.net :: View topic - JMS topic subscribers

schroederms

We have a problem everytime we do maintenace on the AIX box that the queue managers reside on.

First of all we have JAVA applicaiton that Publishes topics, we have a WMQI flow that takes in queue SYSTEM.BROKER.DEFAULT.STREAM and passes them to the PUBLICATION node. We have a durable subscriber that is a JMS subscriber.

What is happening is that we get an error of :
com.pioneer.eai.exceptions.EAIException: MQJMS2008: failed to open MQ queue

OR

The subscribers continually is getting a 2033( no message), which a 2033 is a common for subscribers until a message with that TOPIC is published.

What we do is run ResetSubscription jar manually after we shutdown the subscribing applications. We reset any Subscriber that is in a "u" state to a "i" and then startup the application.

I thought I read somewhere where this ResetSubsctiptio nor a CleanUp type utiltiy runs behind the scenes continuously within JMS. This obvioulsy is not happening.

Question ... Is there something we are not doing properly that is causing this or is this a normal procedure for everyone using JMS Pub/Sub.

Thanks,
Mike
