Somebody knows if exists some program or application that can clear the messages on queues which is handle by other application.
May be sounds a silly question, but Im really novice on this topics. I will take an MQ Class, but at the moment, I'm need your help.
The novice, again. 
Thanks

"Somebody knows if exists some program or application that can clear the messages on queues which is handle by other application. "
---As long as other(any) applications dont open this queue, you could very well issue clear qlocal from within runmqsc.

Unfortuanately, clear qlocal from runmqsc will fail if there IS an application that has an open handle(input or output, AFAIK)
PQEDIT or something will help you here, but I've found the easiest way is to rebuild the sample AMQSGET program and change the buffer size to
the largest size of message your site is likely to encounter. Then just fire
it off and let it squirt all those messages into empty space! (Unix fans can
use /dev/null). A little bit dangerous of course if that's not what you
wanted to do 
Of course, if someone has opened the queue for exclusive input then the
open from AMQSGET (and any other editor) will fail. Use DIS QSTATUS to
find out who has got the queue open, and then use a variety of means:
polite message
subtle threat
gentle kill
kill -9
get his/her boss to fire them  |

Hi,
MQ Visual Edit will also handle this situation. You can do a standard delete or issue a Clear Queue command from within MQ Visual Edit. When the user selects the Clear Queue command within MQ Visual Edit, it first checks if anyone has the queue open. If not, it issue a PCF Clear queue command otherwise it removes the messages issuing a destructive gets.
For more info or to download a 30-day trial of MQ Visual Edit, got to:

Hi,
From the program's source code:
| Quote: |
| AMQSTRG0 is a sample C program that acts as a trigger monitor - reads an initiation queue, then starts the program associated with each trigger message. |
Sure, amqstrg can get messages from a queue but I don't think this is a good example for Bracken to use.

With a little changes (OpenOption & gmoOption to do destructive), the AMQSBCG sample is a good EmpyQ.
