This is sort of a continuation of this
http://www.mqseries.net/phpBB2/viewtopic.php?t=59013
I have a broker 9.0.0.0 test rig setup and working. It is also publishing Monitoring events to the QM (7.5.0.1 running on Server 2008 R2).
I create a subscription to the topic.
| Code: |
DEFINE SUB ('MONITORING.REMOTE') +
DESTQMGR(' ') +
DEST('MONITORING.REMOTE') +
DESTCLAS(PROVIDED) +
EXPIRY(16440) +
PUBACCT(16010515000000A86220826DFB4DBADEC365CAEB0300000000000-
0000000000B) +
PUBAPPID(' ') +
PUBPRTY(ASPUB) +
PSPROP(MSGPROP) +
REQONLY(NO) +
SELECTOR('') +
SUBLEVEL(1) +
SUBSCOPE(ALL) +
SUBUSER('MUSR_MQADMIN') +
TOPICSTR('$SYS/Broker/TESTBRKR/Monitoring/#') +
TOPICOBJ('FlowMonitoring') +
USERDATA(' ') +
VARUSER(ANY) +
WSCHEMA(TOPIC) +
REPLACE

Yet the messages are put on the destination queue with unlimited expiry.
Am I missing something?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Well as indicated in that rather fraught thread you mention, it's my assertion that such messages are always put with unlimited expiry. It's my belief that the EXPIRY parameter of the subscription controls the time to live of the subscription, not the subscribed messages.
In the previous thread our resident perfectionist and training champion indicated a monitoring profile could be used to control expiry time before backtracking rather. I still don't see how you could do that & would be interested in a method. His bracktracking suggestion of an intermediate flow which subscribed and set the expiry could of course be made to work.

Vitor,
I think you might be correct here and that the only way to time-limit the messages published is to run them through a simple broker flow or a dedicated application.
If you aren't using a system with broker then a dedicated application seems to be the only way to do this which seems to me to be an issue with the WMQ base product.
Why is making a published message expire after a set period so difficult? IMHO, it shouldn't be.

Time to compose that RFE perhaps.
