I have a Remote Queue definition on WIN NT server pointing to a local queue in HP UX server. The MQ client will use the REMOTE QMGR NAME AND REMOTE QUEUE NAME to write the message.
The Messages written on to this queue is stuck in Transmission queue without being written on to the local queue on HP UX server. The sender channel in WE BNT Server is allways trying to bind / retry to connect to the HP UX Server without any success.
This setup was working from past 1 year. Suddenly from past 2 days it is not connecting. Please let me what could have gone wrong and how to resolve this issue.
Thanks

Is the listener on the HP-UX box running?
What errors do you see on either side.
Do you know where to look for error logs on NT and HP-UX?
Check the system administration guide from the documentation link on top of the screen. |

Not only the listener on the receiver side needs to be checked but also the channel sequence number could be out of sequence.
The Logs should be able to tell the root cause and a legible solution some times. |

In addition to what Vennela has suggested...check the channel sequence number.
My guess would be that one end or the other got 'bounced' while the channel was still running. |

if the listener is running, check the userid under which it is running.
If that userid is not in the mqm group restart the listener with a userid in the mqm group.
Enjoy  |

In cases where the numbers are off. We have had to..........
Stop both sdr and rcv.
Resolve the sdr.
Reset both
Start the RCV
Start the SDR. _________________ Any opinion expressed is mine, no matter where I got it from, and I retain

The first action to take is to examine the qmgr error logs (in /var/mqm/qmgrs/QMGRNAME/errors) on the SDR and RCVR side to check for channel error msgs at the time of the connection failure. |

The problem was resolved yesterday. The culprit was a setup change in one of the network router where it was not allowing any data fragment above 500k. Since it is a outsourced network we were not aware of this change.
MQ Listner was running with proper userid/permissions. When run in foreground i could see the Listner giving following errors continously
which was also recorded in the LOG files.
AMQ9514: Channel 'WEBNT.CUNIX' is in use.
AMQ9999: Channel program ended abnormally.
There was no other error reported in the log files.
It was surely a misleading errors. Fortunately our Network administrator predicted some issue in the network tunnel between these two servers and checked with the remote admin who maintains this tunnel.
Thanks to all for giving valuable inputs for resolving the issue.
Bye. _________________ G K Mahesh |
