'Lo all,
I have a Java app running on an iSeries or AS400 that reads from a MQ queue and writes to an iSeries dataQ. Works fine, question is, how can I bring it down "gracefully" or cleanly? Any ideas or comments would be appreciated... Thanks.

Code it to quit when the queue is empty, or code it to accept a special shutdown message. Search here for Feedback codes.

Do you mean to just send a "special" message through the MQ queue and check for it. When it is read, then close and disconnect? Thanks...

Exactly so. It is one of the traditional methods.

PS You need some "new" Emoticons with an "attitude"....

MQ Best Practice for terminating a Get Wait Forever.
A thread / program / whatever, puts an empty message on the queue with the MQMD's Feedback set to MQFB_QUIT.
Then in your child thread that reads the queue, you put the following:
| Code: |
if (msg.feedback == MQC.MQFB_QUIT)
{
return;
// or throw an exception - no message or time to quit ...
} |
|
Hey I learn't somthing today. A bit later than jeff did (see the other thread) 
Thanks for the tip Roger. I'm off to incorporate this snip of code into my adapter layer...
