Dave,

That kind of implies you can't start a RQSTR/SVR pair from either side.  Is
that what you were saying?  Because we have a few SVRs and I can start them
up on the sending or receiving side just fine.

The other advantage of a RQSTR/SDR pair is that you can start the channel
from either end (assuming the other end is not in STOPPED state).

Slight clarification here...the RQSTR is intended to start *either* a SVR or
a SDR channel.  The difference between a SVR and a SDR is not whether they
can be started remotely, but what they do when the RQSTR is not the same
QMgr as provided in the SDR/SVR CONNAME.  A SDR will always try to connect
to the QMgr in it's CONNAME whereas a SVR will try to connect to the IP
address and port of the RQSTR that called it.

If a SVR is used simply because there is a RQSTR on the other side, and
without understanding the difference, it may result in an unintended
security exposure.  In the absence of a security exit or SSL, anyone who
knows the name of a SVR can create a RQSTR to start it and divert it to any
arbitrary address.  On the other hand, attempting the same thing with a SDR
results in the SDR starting to it's intended destination.
