By supplying the correct arguments to the correct createSubscriber call.

java novice here. i see the topicsession class with two
methods createDurableSubscriber
this is what i see under one of that
abstrace public interface javax.jms.TopicSession extends java.lang.Object implements
javax.jms.Session
abstract public TYopicSubscriber createDurableSubscriber(Topic arg, String arg) throws
javax.jms.JMSException;
now i dont know where to look for what the createDurableSubscriber method does.
what i am trying to do is
when we try to run more than one durable subscriber with the same clinet ID, we get this
MQRCCF_SUBSCRIPTION_LOCKED Reason code 3156 error.
I am trying to see if there are any options where can set the subscriber to be in some share mode so it would allow what we are trying to do. |

There is a reasonably good section on writing subscribers in the Using Java manual for WebSphere MQ. This in the same place as all the other WebSphere MQ manuals.
There is also a reasonably good - but not JMS focused - manual called Publish/Subscribe User's guide.
Also, you really probably don't need to use a durable subscriber. Remember that business requirements are not the same as technical requirements. Also remember that the entire architecture needs to be taken into account when deciding to use something as potentially troublesome and over-head inducing as durable subscribers.

| thanks. it does have a lot of information, but still cant find what i am looking for. trying to figure out how the <RegOpt> that we use to specify options in the subscriptions registration message in a MQ message map to a JMS message, it dont look like it is in the create durablesubscriber method. |

NOT RELEVANT in JMS. Read the manuals.
What you can set up however is a specific queue to hold your subscription and then have multiple consumers share in retrieving the messages from the queue (scaling pattern).
Enjoy  |
