Actually, I was able to successfully send a message from the ME through the MQ link I defined to the queue manager(QMgr).
However, I couldn't send a reply from the QMgr to the ME and I found a problem that the sender channel on the QMgr didn't work.
Now I have no idea how I can start a sender channel on the QMgr.

The name of sender/receiver channel on the MQ link is exactly the same as the name of receiver/sender channels on the QMgr.
I defined the sender channel on the QMgr like
CHL(MQ.TO.SIBUS)
CHLTYPE(SDR)
TRPTYPE(TCP)
XMITQ(SIBUS)
CONNAME('SERVER(5558)').

When I tried to start the sender channel on MQ side, it didn't start with the status 'binding...'.
(By using 'netstat' command, I can see that my WAS is listening 5558 port).
I know that the status 'binding' may be caused by accessing an invalid port.


Thanks!
