Hi All, we have a situation where we have set our CAPEXPRY for 24 hours in our local Q, Sending application has send around 1000 messages but receiving application is down and not yet fixed. Now when the message arrived in the Queue because the CAPEXPRY was 24 hours , so all the messages has their expiry interval set to 24 hours.

Can I move these message to another Local Q which has CAPEXPRY of 5 days and will that change these messages new expiry time to 5 days?
I just want to save these messages , we can't take backup to a file because of some restrictions so looking for innovative suggestions here.

Nope. The doc clearly states "...An expiry time specified by an application, which is lower than the CAPEXPRY value will be used...".

RfhUtil and GET/PUT with a new expiry value?

Hi Exerk, I think I got what you mean. when the source application put message into Local Q#1 which has expiry of 24 hours, it sets the expiry of messgage to 24 hours. Now, I cant change this value it even if I move those message to another queue with capexpry of 5 days using QLOAD program .
So once a value has been set, it is set, until it is a lower value. right?

Correct, because the messages have an expiry value lower than CAPEXPRY, which doesn't set the expiry but caps the expiry. Clue's in the name.

But:

This would work, or a few lines of C/Java/PHP/MQ aware language of your choice.

You set CAPEXPRY because of design decision regarding quality of service. The messages are disposable after 24 hours. You should review the decision on this queue and other queues. In general, MQ message expiry should only ever be used if messages have a finite useful life.
