I'm running a Queue Manager since the last year and at the recently weeks I'm passing through a very annoying problem.
At repeated times in a day the Sender Channel stop working and stay at Calling or Trying Again, just don't connect until I force stop it and start it again aftear waiting 1 minute or more.
The Queue Manager are configured with:
AdoptNewMCA: ALL;
AdoptNewMCACheck: ALL;
AdoptMCATimeout: 10
And the Sender channel:
Heartbeat Interval (HBINT): 5;
Disconnect Interval (DISCINT): 0.
Short Retry Count (SHORTRTY): 100;
Short Retry Interval (SHORTTMR): 5;
Long Retry Interval (LONGTMR): 30.
All the other configuration are just the defaults.
Searching about the cause, I have only found this (on windows Event Viewer):
"Event Type: Error
Event Source: WebSphere MQ
Event Category: None
Event ID: 9558
Date: 23/3/2009
Time: 15:31:56
User: N/A
Computer: W2K3-C-SMQ-01
Description:
Remote Channel is not currently available.
The channel program ended because the channel 'C.IF_633.PRODESP.01' is not currently available on the remote system. This could be because the channel is disabled or that the remote system does not have sufficient resources to run a further channel.
Check the remote system to ensure that the channel is available to run, and retry the operation."
Could anyone help me out? Is there any configuration missed?
If you need more information, ask for them and I'll post it.
Best Regards for all,
Osnildo |

Is it? Does it? Did you?
WMQ version? OS version?

This suggests that the problem lies with the receiving end, not your end. Have those responsible for the remote end check resources etc. and see what correlates to the time stamp at your end.

The sender channel that is having proble is the C.IF_633.PRODESP.01, this one Start, keep Running and after some time it goes to Retrying and Calling status.
The versions are: WMQ 6.0 in an Windows Server 2003 R2
Initially I think that the problem is with the other end, but as I already talked with they network and MQ people various times, I started thinking the problem is here, because they run MQ for various others and don't have any problems at all, and only our channel keeps falling.
At now, I followed a recommendation that I have received from the developerWorks forum in the IBM site and modified the HBINT and SHORTTMR to 30. |

imho and from my experience, the problem is at the remote end or maybe somewhere in the network. 5 seconds heartbeat is quite short, 5 seconds short retry and 30 seconds long retry are very low values. is there a special reason for these low values?

And just for clarity... check both your local QM and the remote log files as it seems likely that the remote QM has the issue (as indicated by others in this thread). |

I really don't know the reason for this values, but have received they as recommended by the people from the other company that we communicate with MQ.

In the amqerror*.log appears the same error as in the Event Viewer, but in portuguese (as it's my main language and I have the MQ installed in this one)

I don't have access to the Remote side, it's controlled by other company.
After speaking with the company that monitors the other side one more time, we are able to discover what are causing the problem:
Apparently some incorrect package are going to the Remote End and when they receive that package their system restart our channel but sometimes this restart wasn't doing correctly.
With the changes in the HBINT and SHORTTMR to 30 the Channel are running for 9 hours without any stopping, but I'm still having the problem with the "incorrect package" that I don't know from where it's coming.
Now, we are planning to update the WMQ to version 6.2.16 to see if it resolves the problem. |

Have you noticed the little buttons at the bottom of all the posts? Including the one that says "email"? Guess what it does.
If you don't want to guess, push the email button on one of your posts and see what happens.

Really? I'll report that to the admin; it's against forum rules. 
The PM button should still work. Until he's booted for supplying an invalid email.

Really? Because yours doesn't have one either!  (nor does mine) 
I know that if I get a PM I get an email though, maybe this is what you are thinking about? |
