a tip for the loopback testing. I do this all the time to prove the MQ
network is up. I don't bother telling the other side to create a remote
queue def.

Instead, I send a message to a bogus queue name on their QM, and I set the
report options to discard (so no message goes to their DLQ), plus Exception
with full data (so I get a report message back, proving the round trip) and
COA with full data (just in case they made a queue called
"zjn4n329r2on0bfiowbu1"). I set the reply to info appropriatly.

In this fashion, I can test without them even knowing, and I don't have to
rely on the other side for setting up any queues (other than the transmit
queue back to me).

Michael,

We don't get a lot of Production Support calls.  We did when the group was
first formed (in fact that's why the group was formed) but over the years
we've tuned the WMQ network quite well and trained the developers on the use
of WMQ to the point that we have very few problems and they are usually not
actual MQ problems but application or administrative problems.  So it's not
like we have anything better to do when the call comes in!  Production
support is our number one priority and if a WMQ interface is down for
whatever reason at least one of our analysts is on the problem until service
is restored, working in shifts 24x7 if necessary.  In addition to using
RQSTR channels, we also insist our business partners set up QRemotes so we
can send loopback messages over the channels to test them.  This gives us
limited visibility to check the health of their WMQ network.

If the outage touches WMQ at all, we are in for the duration so we have a
very strong incentive to minimize the outage time.  By extending our
infrastructure and visibility into the edges or first layer of the 3rd party
MQ network, we are in an excellent position to perform early diagnostics
while the help desk and or second tier at the third party are still getting
pulled into the call.  We would be foolish to have these capabilities and
not use them when it's our customers and our money that are at risk.

Rob,
good points! but then you are doing the pre-Problem detirmination for your
'business' user who is expecting something and working from taget to source.

I always tell my 'business' user if they did not get what they expected to
call
their 'business' user supplier (aka the sender party) and track the message
from
the source to the target. 99% of the cases it's a situation like 1) and 2)
you
described only this time it's the companies 'business' user calling their
own
helpdesk or support group and he/she often is known to that group.
AND most importantly keeps my support group free of unneccessary calls as
often
they can't do anything but just 'narrowing' down the problem and passing on
the call...

Michael
