Can you have a 'shutdown' command that runs a program to send a report
message to the app? With a feedback code of MQFB_QUIT ? The app /
service would have to be modified to look for this type of message and
feedback code.

Tim,
Yep, sure did. MQGMO_FAIL_IF_QUIESCING happens when the queue manager is
shutting down. That's not the problem. The problem is terminating a
WIN32 Client service gracefully when the service is in a blocked MQGET
read. It appears there isn't any way except to wait or issue a
::TerminateThread which works but generates a ton of memory leaks. It
would be nice if IBM would code an event handle that could be included
as a parameter when issuing a MQGET. Then when signaled the MQGET would
return out of the read. Another alternative is simply to "PUT" a message
onto the "GET" queue prior to shutdown. This will break the blocked
MQGET read as a message is readily available. I'm looking at that
method as the best means of gracefully shutting down. However, I don't
know how well that method will be received since I'm only supposed to be
receiving messages from that queue. Therefore the hunt for an
additional solution goes on....
Thanks for the reply!
Steve

Did you code MQGMO_FAIL_IF_QUIESCING? Note you should also code the
MQOO_ equivalent etc.

Please respond to
MQSeries List
Hello,
I have an application which one of the prerequisites is to call
MQGET with a minimum 120 second WaitInterval! This application is using
MQSeries 5.3 client on a WIN32 platform and runs as a service. The
minimum 120 second interval is there to supposedly keep the bandwidth
down to a minimum. However, the problem is with WIN32 the Service
Control Manager times out and cannot shut down the service in a timely
fashion. MQGET will only return if the WaitInterval has expired or a
message is received. My only solution is to put a message onto the "GET
Queue" prior to shutdown to force an exit out of the blocked read. I
was hoping for a more elegant solution on WIN32. Are there any other
ways to "signal" a blocked MQI MQGET on Win32 to exit?
Thanks much!
Steve
