explain why you would do a browse instead of a get by correlationID?

You are again not telling why you do not want to consume the message...

Is it not possible to browse the message rather than getting the message and deleting it form the queue.My requirement is to browse the message from the queue and process the message .also i believe by doing this we can avoid the losing of message.
I needed the corresponding numbers for
MQGMO_BROWSE_NEXT and MQGMO_LOCK and
MQGMO_BROWSE_MSG_UNDER_CURSOR
MQGMO_BROWSE_NEXT = 32
MQGMO_LOCK = 512
MQGMO_UNLOCK = 1024
MQGMO_BROWSE_MSG_UNDER_CURSOR = 2048
This is what i find from interface "MQC"
I believe to have the OR operation to use together .
Correct me if am wrong... |

Yes, OR is a correct operation to use to accumulate MQGMO option values.
One can usually also use + instead of OR.
There is more than one way to consume a message from a queue without risking it being lost.
The *usual* way of doing so is to use a *transaction*, instead of using browse with lock. |

Hi All,
I am able to lock the message's in the queue using MQGMO Lock using 512 and also along with 32(browse next).
Tried using 1024 for UNLOCKING... did not work 
Could anyone please help in UNLOCKING the message in the Queue.

That's not a requirement, that's an implementation. What's the actual requirement?

I believe you're right. I also believe this is considerably more resource expensive than the normal way of avoiding the loss of a message (using a transaction) as well as requiring more extensive and complex code.
As you've discovered.
