The MQ DEF below does a simple routing of messages.

QM: A

DEFINE QREMOTE('QM1.RQSTIN') RNAME('QM1.RQSTIN') RQMNAME('C') XMITQ('B.XMIT') PUT(ENABLED)

DEFINE QLOCAL('B.XMIT') USAGE(XMITQ) TRIGGER TRIGDATA('A.B') TRIGTYPE(FIRST) PUT(ENABLED) GET(ENABLED)

DEFINE CHANNEL('A.B') CHLTYPE(SDR) TRPTYPE(TCP) XMITQ('B.XMIT') CONNAME('localhost(1414)')

QM: B

DEFINE QREMOTE('C') RQNAME('C') XMITQ('C.XMIT') PUT(ENABLED)

DEFINE QLOCAL('C.XMIT') USAGE(XMITQ) TRIGGER TRIGDATA('B.C') TRIGTYPE(FIRST) PUT(ENABLED) GET(ENABLED)

DEFINE CHANNEL('B.C') CHLTYPE(SDR) TRPTYPE(TCP) XMITQ('C.XMIT') CONNAME('localhost(1415)')

DEFINE CHANNEL('A.B') CHLTYPE(RCVR) TRPTYPE(TCP)

QM: C

DEFINE CHANNEL('B.C') CHLTYPE(RCVR) TRPTYPE(TCP)

DEFINE QLOCAL('QM1.RQSTIN') USAGE(NORMAL) PUT(ENABLED) GET(ENABLED)


One thing that im not clear about is in QM: B where

DEFINE QREMOTE('C') RQMNAME('C') XMITQ('C.XMIT') PUT(ENABLED)

usually will include the RNAME('') attribute.

But even without specifying the RNAME('') attribute it still works. So what is the difference?. Code optimization is accomplished without specifying RNAME('') attribute?. Or is it purely just the standards in which we follow?

A few pointers...
You set your xmitq to trigger but you did not specify the initq to be system.channel.initq.....

As for your question read the intercommunications manual and more specifically the passage about qmgr alias...

Enjoy

According to the intercommunications manual, the QMA is created using a Remote Queue Definition that has a blank RNAME.


But then without the use of RNAME it still works

This explains why I need to specify the blank RNAME in my Remote Queue Definition.

You don't need the QR in queue manager B to hop the messages through, only the XMITQ to queue manager C provided the XMITQ has exactly the same name as queue manager C.
