Hello All,
We are facing the following issue:
Sender channel going to retrying state ,since receiver channel going paused state after few seconds continuosly even after stopping/resetting/restarting the channel.It happened twice.
Error LOG Info:
EXPLANATION:
The channel program ended because an instance of Channel 'xxx.yyy' could not be started on the remote system. This could be for one of the following reasons:
The channel is disabled.
The remote system does not have sufficient resources to run another instance of the channel.
In the case of a client-connection channel, the limit on the number of
instances configured for the remote server-connection channel was reached.
ACTION:
Check the remote system to ensure that the channel is able to run. Try the
operation again.

Is the FDC from the sender end? Or receiver end?
If from the sender end, what errors did you discover in the error logs of the receiver qmgr?
Channel ends negotiate max msg length. Increase max msg length on both ends of the channel - to the size of the largest message the channel will need to transport.

The error info belongs to sender side.So Increased max msg length at receiver side and messages got transmitted to receiver side.
Thanks |

Did you research the error on the receiving end of the channel? Did you just guess at the resolution?

| I observed receiver channel is going to paused state continuously after restarting.So first i increased the msg length at receiver side and restarted the channel.It worked out. |

why did you change message length? just a random action to see if it helps? why dont you check the error logs on the receiving end for the real cause?
in addition, the pausing of the receiver could be by the channel retrying to put messages to its destination (imho). so you may also want to review the retry parameters of the receiving channel to verify if that is really what you want.

Did you research the WMQ Intercommunications manual to discover what PAUSED state means?

(I know this was an old post but it came up in a google search on the same issue)
Any body have any guesses on this ...
We have the exact same error occuring our our WAN link connected via MQ sdr/rcvr channel and we are trying to determine if it is an underlying WAN issue as we are seeing unusual number of packet losses on this link.
What exactly would be the resource that would be insufficient (other two possible causes are not applicable ...)

Channels seem to restart in every case without intervention by admins.

Exact same? Same FDC? Same errors in logs in both qmgr- and WMQ-error directories?
PAUSED means waiting for retry interval to pop.

Ok! Not identical as no FDC file was generated at least on the sdr side ... don't know about the receiver side at this time.
But this error I believe a amqerror 9228 ... don't have the report in front of me.
