I am using MQ 5.3 csd10 on solaris and have created a queue manager, sender channel - channel1 & receiver channel - channel2.
channel1:
channel(channel1) trptype(tcp) xmitq(QM_MQBUS) chltype(sdr) conname('localhost(5558)')

channel2:
channel(channel2) trptype(tcp) chltype(rcvr)

I have create MQ Link in WAS 6.0.2.17 and created reciever channel - channel1 & sender channel - channel2
channel2:
hostname - localhost
Port - 1414

When I start the sender channel - channel1 in MQ, the channel goes in the retrying state and error log shows:
-----------------------------------------------------
AMQ9520: Channel not defined remotely.

EXPLANATION:
There is no definition of channel 'CHANNEL1' at the remote location.
ACTION:
Add an appropriate definition to the remote hosts list of defined channels and retry the operation.
-------------------------------------------------------

It seems that the MQ sender channel is recognising/communicating with the WAS receiver channel - both have the same names.

How can I make them know each other?

Put the lower case channel name in quotes or it gets folded to uppercase and in MQ case counts

All the channel names (in MQ & WAS) are in uppercase. I should have mentioned/written in my original post.

Let me explain more:

MQ & WAS 6.0.27 are on the same machine - solaris.
Sender & receiver channels are defined both in MQ & WAS MQ link.

Sender channel in MQ has the same name as receiver channel in WAS MQ link. (same for reciever channel)

I'm not familiar with was 6 ESB.

but in MQ sender channel and receiver channel shoul have the same name

Example:

Code:
channel1:
channel(QM1/QM2) trptype(tcp) xmitq(QM_MQBUS) chltype(sdr) conname('localhost(5558)')

channel2:
channel(QM1/QM2) trptype(tcp) chltype(rcvr)


I think that QM channel and WAS channel is totally different thing.

I hope I'm right

kevinf2349, you were right.

The problem was due to the mismatch of 'case' in the channels.
The channels were changed to uppercase in WAS but WAS was not restarted (only the channels were) so they did not come into effect.

Thanks everyone.[/img]
