 To check how the TMS for WebSphere MQ Series has been settled (piece of Tuxedo configuration file) :





There is a machine mac-A on which Tuxedo application runs and on which a MQ Series application runs too.

However, Tuxedo must connect to ANOTHER MQ Series application running on a REMOTE machine mac-B.

That is why CHANNEL and CONNAME parameters are required by WebsSphere MQ Series to allow a remote connection from Tuxedo Application available on mac-B to connect to the MQ Series Queue Manager running on mac-A.
