Hi All,
So long i post my last one. I have a wierd problem occuring in our environment. We are using Windows Server 2003, MQ V 6.0.2.9. I just changed the 'conname' and pinged the channel at the sender side. It is throwing a 2195 error. and checked that we are getting wrong error details like below.
The operation requested cannot be performed on channel 'NLLGS1.NLGOA1.01'. Some
operations are only valid for certain channel types. For example, you can only
ping a channel from the end sending the message.
ACTION:
Check whether the channel name is specified correctly. If it is check that the
channel has been defined correctly.
but i see that i have pinged from the right end.
EXPLANATION:
The operation requested cannot be performed because channel 'NLLGS1.NLGOA1.01'
on the remote machine is not of a suitable type. For example, if the local
channel is defined as a sender the remote machine must define its channel as
either a receiver or requester.
ACTION:
Check that the channel name is specified correctly. If it is, check that the
remote channel has been defined correctly.
But I verified that the channel type is 'receiver' .
Can anyone let me know if this is some kind of bug. I recreated the channel it worked fine. But not sure if i can do the same in production. I need suggessions , how would i rectify this without restart of server or queue managers.

Was the channel in STOP state before you made the change, or did you stop/start the channel after the change?

Channel in inactive. I have stopped and started after the change. That did not work . I restarted queue manager and server too after much shooting. But no luck. so had recreated finally, which worked. All am worrying is about production , where i cannot do these things. So checking if there is anything else which i can look for fixing it

| If you can recreate this, probably you should open a PMR. |

Anything else that can be done now, other than PMR?

the 're create' in my earlier post was regarding channel, but not the issue. But we have to different things one in non prod and other in prod. I am able to resolve this is non Prod by re creating the channel. But in Prod a similar issue with different setup totally, i cannot do that. That is why am asking this.

Hi Nathan,
Both issues are the same 2195 when we ping the channel and if we try starting them they retry. But the projects are different, between different queue managers/Servers, different versions 6.0.2.7 in prod and 6.0.2.9 in non prod.

If you go back to the machine in which you recreated the channel, and you AGAIN change the conname, do you get the 2195 AGAIN?
Can you re-create the issue on the test environment?
If you can't then you can't troubleshoot it.
If you CAN re-create the issue on the test environment, then you can do more diagnostics, including confirming that the receiver side thinks the channel has actually started. |

No I dont think if i can recreate the problem. But I can try doing what we did earlier and check if we come across same situation. I will update you tomorrow with the outcome. But if you find anything of same sort, please let me know. Thanks for all your support.

After changing the channel, have you stopped it and restarted it?
Did you ping the channel after you stopped it?

PING works only on a non-started sender channel.

Well I would expect an FDC to be produced with a 2195.
Did you find a corresponding FDC?

No FDC's generated. That's what is puzzling me.
How would i experiment on a situation like this to recreate and raise a PMR or how to diagnose this problem without FDC's and wierd errors in logs. Need help  Thanks in advance.
