Hi,
How do I remove messages from the LQ without actually using MQGET in any of its forms...
Thank you. |

There's only one MQGET, it just takes different options.
Do you mean programatically or administratively? It's the only way within a program, but adminsitrators can use clear queue commands.

its Administratively...actually my sender is JMS complaint while reciver is not...so the receiver can't understand the message and cant MQGET it ...
I just wanted to refresh the queues..i couldn't remember how....

Then the System Admin guide will be your new best friend.

Not strictly true btw - message content is irrelevant to the get. The receiver may not be able to interpret the message immediately, but even that's a fairly straigtforward job of removing (or interpreting) the RFH2 header JMS has added.

Have your JMS sender use an URI for the Destination definition and make sure they add the targetClient part:
| Code: |
| session.createQueue("queue://MYQMGR/DESTINATIONQUEUE?targetClient=1"); |
This should allow your non JMS program to read the message without problems.
Enjoy

I would greatly appreciate it if you explain the code
thank you

It is all explained in the using Java manual (link documentation at the top of the page ...
This is the programmatic equivalent of the JNDI setting target client = MQ.
Enjoy

There's a Java manual you might find an informative read but in summary JMS adds a header to it's messages which is used for various purposes described in the manual & which I don't plan to repeat here. This information is (obviously) added to the MQ message in the form of an RFH2 header. A JMS application reading the message will expect this header, a non-JMS will not.
You therefore have 2 options - code the non-JMS application to expect & process the extra header information or use the code supplied by fjb_saper to suppress the header.
Searching either this forum or the manual for 'targetclient' would have yielded much the same information, and you wouldn't have had the delay in receiving a response.
I also commend the Java manual to you if you want a more detailed explaination of the mapping between JMS and MQMD/MQRFH2 than the rather simplistic one I've given here.
