How do I find sender channel for a given receiver channel?

It is easy to find Reeceiver channel for a given sender channel, using connection name.


Thanks

That's what the naming conventions are for.

May be you ca use netstat -an, but that will give you the IP's of all the inbound channel IP's. You then have to narrow down.

Or may be there are tools

Name on both side has to be the same to work That is fine.

Now, my concern is, for instance,

Machine A:
SDR_CHNL (chnl type: SDR) with Connection name (Machine C)

Machine B:
SDR_CHNL (chnl type: SDR) with Connection name (Machine C)

Machine C:
SDR_CHNL (chnl type: RCVR)

I know that it should not be. We are currently facing this kind of problem (Could not clearly conclude what is the problem)


Thanks for your inputs.
Shiva.

If you use a naming convention for your channels that is uses the sending and receiving queue manager in the name of the channel would resolve the issue.

Cheers, Jan.

So, can I define two sender channels (from different q-mgrs) pointing to one receiving channel on the target q-mgr? Of course, only one will be active at any time. I showed this scenario in my sample (previous message)

Thanks
Shiva.

You can do that but why do you want to do that? Why don't you have two different pair of channels.

If you have three machines called
M1
M2
and M3

Then have SDR channels defined something like
M2.TO.M1
M3.TO.M1
etc.

This way if you have a RCVR channel with name M2.TO.M1 on box M1 then you will by the name know that the channels other end is on box M2.

That's a goo thing. You have really reached my problem.

I have not done it wantedly. It happened by mistake. Two sender channels pointing to same receiver cahnnel and we were troubleshooting the problem for some hours. That means, somebody deceived the system. I feel this must not happen. Receiver must have reference to sender channel!!! ... What do you say? If not how do you prevent this kind of error?

Thanks
Shiva.

Can you have a shot,

when there is no traffic between three QMGR's then send a message from Machine a to machine C . Then see the last message time parameter on the channel. If it is same as the present time then you are done, else try for the Machine B in the same process
