Re: Strange problem in MQSeries
Another reason might be... As put and get is done under syncpoint, which is default in OS/390, if you are not COMMITting right after MQPUTs these uncommitted messages will contribute to the current-depth. Therefore, the MQINQ will show the correct number of messages on the queue. However, you cannot MQGET them until you have committed them.

Re: Strange problem in MQSeries
Sounds like the messages have expired. They would count on the MQINQ but would disappear after a MQGET. What does the MQINQ return after the MQGET? Nick -Original Message- From: Riyaz [mailto:[EMAIL PROTECTED] Sent: Thursday, October 23, 2003 2:37 AM To: [EMAIL PROTECTED] Subject: Strange problem in MQSeries Hi, The problem - Some messages were added to few queues in a Q manager using a COBOL program. The number of messages that were added was verified by issuing a MQINQ call and checking the message count. The same number of messages could be fetched using MQGET. However after some time (say overnight), when an MQINQ is issued, the message count returned is proper and corresponds to the number of messages added. However if an MQGET is issued on the same queue immediately after MQINQ, no messages are fetched and the MQGET fails with 2033 (i.e. no messages available)! Simply put - the MQINQ returns a proper message count but the MQGET says that no messages are available. This behaviour was not exhibited earlier. The setup is MQSeries on OS/390. What could be reason for this? Could it be because of any changes in the way messages are stored (something to do with the storage classes being changed)? Thanks in advance, Riyaz.
