Hello,

we have a JMS application who would like to use XA with MQ 6.

MQ <-> application server <-> DB

the application server is the syncpoint coordinator.



We have troubles finding a guideline what we need to configure.
at this point we have defined JNDI objects:

a com.ibm.mq.jms.MQXAQueueConnectionFactory
a com.ibm.mq.jms.MQQueueConnectionFactory
and some MQQueues.

without XA it works, but with XA we get following error:

javax.jms.JMSException: MQJMS1068: failed to obtain XAResource

Do we need to configure a XA resource manager on the MQ side?
Even if MQ is not the syncpoint coordinator?

Do we need to use WebSphere MQ Extended Transactional Client ?


If we need to configure something on the MQ side, does anybody has an example?


Update:
this is the fault under the above fault:
Code:

javax.transaction.xa.XAException: client connection not XA enabled
   at com.ibm.mq.MQXAResource.createXAException(MQXAResource.java:794)
   at com.ibm.mq.MQSESSIONClient.XAOPEN(MQSESSIONClient.java:458)
   at com.ibm.mq.MQXAResource.<init>(MQXAResource.java:110)
   at com.ibm.mq.MQXAQueueManager.getXAResource(MQXAQueueManager.java:270)
   at com.ibm.mq.jms.MQXAQueueConnection.createXAQueueSession(MQXAQueueConnection.java:101)



thx


Pieter

No.

You could use a bindings connection a local queue manager instead.

But you can't do XA with a client connection, unless you use the ETC.

Remember that the ETC is licensed at the same cost as a Qmgr.
