HI guys,

i am experiencing a strange problem. we have Front end windows QM communicationg with unix box QM in cluster. In the unix we have broker and sending the response for request from FE. I am not getting the response to FE and getting the below error in the logs after processing successfully by broker.

EXPLANATION:
An error occurred sending data over TCP/IP to 10.X.X.2. This may be due to a
communications failure.
ACTION:
The return code from the TCP/IP(write) call was 32 X('20'). Record these values
and tell your systems administrator.

Help is highly appriciated.

regards

from the unix box do a telnet with the info in the conname of the channel
ex: telnet tgthost 1414
ctrl+]
quit

If you don't get a blank screen after the telnet you need to fix your tcp/ip stuff first...(including firewall)

Enjoy

Time to check the cluster receiver on FE.

Make sure the right cluster name (list) is specified on it.

Check the FR using dis clusqmgr(*) and verify the FE is seen as cluster member....
Check the FE (PR) using dis clusqmgr(*) and verify there is no temp qmgr in the cluster....

In order to interpret this errno we would need to know what type of system it is (AIX / Solaris , etc.) Also, is this a recent error? Does it happen all the time? Thanks
