I want to lock a message from other users of the queue and release it later....
I found an option of MQC.MQGMO_LOCK.....but this is giving me an error mqrc 2046(OPTIONS_ERROR) when used with MQC.MQGMO_MSG_UNDER_CURSOR..
The queue open options are
openOptions = MQC.MQOO_INQUIRE | MQC.MQOO_INPUT_SHARED | MQC.MQOO_BROWSE
Can someone suggest the correct options to use.......I have to use browse through queue and then lock the message which matches the message id I have...... |

| Use BROWSE and LOCK together. When you have found the msg you want, get it without BROWSE and with MSG_UNDER_CURSOR. This is covered in exhaustive detail in the APR, MQGMO Options. |

I went though the APR.........
As u said, i first browse and then get....
I first used the BROWSE option.........
Once i found the message i used the LOCK and BROWSE_MSG_UNDER_CURSOR...........
My message was locked and not removed just as i want it but when i opened another instance of the same application and ran it, it started showing me mqrc 2033 error....
How can i make the other program exclude or overlook locked messages in the queue.....????? |

If you locked the messages and your second program got a 2033 (no message available), then I'd say things are working. |

What is the criteria for getting messages in your second program?
