Hi All,

We have a hub-spoke architecture, the communication medium being MQ Series. Now, my question is can we have two client channel(with same name) in our hub pointing to two different spokes(with different conname) ?


Example:
DEFINE CHANNEL(NT.T.QMGR1.CLNT) +
CHLTYPE(CLNTCONN) +
CONNAME('X.Y.Z.A(1414)') TRPTYPE(TCP) +
DESCR('CLIENT CONNECTION CHANNEL from NT to QMGR1') +
HBINT(15) MAXMSGL(104857600) +
QMNAME('QMGR1') +
RCVDATA(' ') RCVEXIT(' ') +
SCYDATA(' ') SCYEXIT(' ') +
SENDDATA(' ') SENDEXIT(' ') +
TPNAME(' ') USERID(' ') NOREPLACE

DEFINE CHANNEL(NT.T.QMGR1.CLNT) +
CHLTYPE(CLNTCONN) +
CONNAME('A.B.C.D(1414)') TRPTYPE(TCP) +
DESCR('CLIENT CONNECTION CHANNEL from NT to QMGR1') +
HBINT(15) MAXMSGL(104857600) +
QMNAME('QMGR1') +
RCVDATA(' ') RCVEXIT(' ') +
SCYDATA(' ') SCYEXIT(' ') +
SENDDATA(' ') SENDEXIT(' ') +
TPNAME(' ') USERID(' ') NOREPLACE


In the above example, can we define both the channels on hub with the same channel name but with different connection name? Thanks in advance.

Note: This info gets updated in Tab file.

You cant able to create the same channel twice with same name.

it will throw an error "Object Already Exists"

Best convincing idea is try out once...

In CONNAME one must specify the connection details of the server.

If you are looking to connect to two spokes from jub, then you need to create client connection channel on the spoke
