What is the environment....i mean, r u running an MQ client/server, windows/AIX....what version of MQ..

MQQueueManager theQueueManager = new MQQueueManager("QM.TEST");
theQueueManager.begin();
MQQueue queue = theQueueManager.accessQueue(QUEUE_NAME, MQC.MQOO_INPUT_AS_Q_DEF| MQC.MQOO_OUTPUT, null, null, null);
MQMessage msg = new MQMessage();
MQPutMessageOptions pmo = new MQPutMessageOptions();
queue.put(msg, pmo);

Hi balareddy,
I guess you will be running the queue managers before you run your application 
there is no need to use that line for starting the queue manager...you can do away with it and try...there are some samples here on the forum....try those.
Regards. |

Actually i tried XA with MQ java. i configured ini file and acreated switch file for Oralce. that time it gave 2121 error. so i narrowed down where the problem accurs. i removed Oracle code fully and tried with QM.Begin(). it throws the same error.
I thought 2121 problem is only with QM java not when using XA.

This calls MQBEGIN. MQBEGIN tries to begin a global unit of work. Otherwise known as a distributed unit of work. Or a two-phase commit transaction. (I bet there are other alternative terms too).
If you have no XAResourceManager stanza in your qm.ini file, you will get failure of MQBEGIN, with reason code MQRC_NO_EXTERNAL_PARTICIPANTS (2121).

Since you are not using a database in this example, remove the qmgr.begin() call.
Another important point: if you want to start an MQ-only unit of work, you'll have to put MQPMO_SYNCPOINT in the pmo.
See http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/topic/com.ibm.mq.csqzak.doc/csqzak10255.htm
If it still fails, post again with the amended source - it really helps us understand what's going on.
Hope this helps |
