Hello,
I'm trying to write a Java application which issues MQ commands on a Queue Manager. However, I always receive error 2042 when I try to open the "SYSTEM.ADMIN.COMMAND.QUEUE" queue.
My code looks like that :
| Code: |
MQQueueManager qMgr = new MQQueueManager("BLAH");
int openOptions = MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_SHARED;
MQQueue system_default_local_queue = Mgr.accessQueue("SYSTEM.ADMIN.COMMAND.QUEUE", openOptions);
|
I have no other applications connected to the Queue Manager (It is a local server).
Is there something I missed ? What am I doing wrong ?
TYIA, |

Why are you using any input options opening the queue.  I thought the command server used open exclusive....

In fact I tried different values for openOptions but all of them generates an error.
| Code: |
| int openOptions = MQC.MQOO_INPUT_EXCLUSIVE; |
alone and
| Code: |
| int openOptions = MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_EXCLUSIVE; |
gives an error 2042 as well.

Not too surprising as the command server opens this with exclusive input.
Your program is not replacing the command server! Why are you trying to read this queue anyway?
You should be putting to it, and specifying a reply queue for the response. |

Wow. You truly don't understand what you are trying to accomplish.
Please read the manual. You should ONLY be writing to the command queue.
| Code: |
| int openOptions = MQC.MQOO_OUTPUT | MQC.MQOO_FAIL_IF_QUIESCING; |
