This isn't a request for help, but I messed up and kept getting a 2026 on the Get from a queue, and it took me a while to figure out what the problem was. I've done this before, but had forgotten precisely what the solution was. If it happens that someone else runs into this and comes here for help, well, I have a suggestion!
Anyway, in C# code I declared an instance of an MQMessage and left its value null in the declaration. Much later down in the code after opening to the queue manager and accessing the queue I performed a Get and kept getting a 2026. A few hours later and consultation with manuals, user groups and so on I finally figured it out. Again.
When doing the Get the MQMessage it was supposed to be using to put the message into was not instantiated, but it was a null object. Of course this meant that the Message Description was messed up!
You need to instantiate the MQMessage before using it in the Get or else you get a 2026. See the code below:
| Code: |
MQQueue mqQ = mqQMgr.AccessQueue(QName,
MQC.MQOO_FAIL_IF_QUIESCING
+ MQC.MQOO_INPUT_AS_Q_DEF
+ MQC.MQOO_SET);
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.WaitInterval = 500;
gmo.Options =
MQC.MQGMO_CONVERT +
MQC.MQGMO_ACCEPT_TRUNCATED_MSG;
MQMessage mqMsg = new MQMessage();
mqQ.Get(mqMsg, gmo);
|
So make sure you have instantiated the MQMessage before using it in a Get!
