Hello Everybody,
I am would like to to copy a message from a queue to text file using MQGET and want to clear the queue. After done with my processing(Not related to the message..), I would like to read the message from the file and would like to put the message back to the queue. But I do not want the information like PUT/DATE TIME and USERID and FORMAT etc.. options exactly same as the original message which I have received thru MQGET, that way nobody should notice any difference with the message.
I am using JAVA to do this.
Can somebody guide me how I can get the same parameters as the original message.
Thanks |

Are you writing complete message (including header information) in the file? If so, you may set the same values for each field in MQMD Header while putting back the message on the queue.

Hi
Use Identity Context so that no one can find that. But you should be having that permission to do.
USe MQOO_PASS_ALL_CONTEXT in the open call and MQPMO_PASS_ALL_CONTEXT in the put message option.
Read Application Programming Guide for this.
Bye

Here's another question: perhaps you don't need to do this at all. Instead of physically removing the message from the queue, why not just use the browse option on your MQGETs, such that you get all the information contained within the message (along with the header) and you can do whatever processing you require. Programmatically increase the cursor one by one to browse each message on the queue in FIFO order until you come to the end. Once you get the 2030 error, you know you've processed everything, and it's still there on the queue for you. Perhaps this may not work in your particular situation, but there's probably some other tricks you can do in order to achieve the required effect without actually having to replace messages on the queue.
