Hi,

We are Configured DQM setup from AIX(MQ 8.0.0.6) TO Windows(MQ 7.5.0.2) Server. We are facing frequent channel retrying issues, But from Windows to AIX it is working fine. I am confusing that issue is with MQ Related or Network related or OS related.

These error logs we observed.
12/20/17 10:03:48 - Process(28246212.1) User(mqm) Program(runmqchl)
Host(PRACEM) Installation(Installation1)
VRMF(8.0.0.7) QMgr(QM_PROD)

AMQ9209: Connection to host '10.59.158.179(1415)' for channel 'AIX.TO.USD'
closed.

EXPLANATION:
An error occurred receiving data from '10.59.158.179(1415)' over TCP/IP. The
connection to the remote host has unexpectedly terminated.

The channel name is 'AIX.TO.USD'; in some cases it cannot be determined and
so is shown as '????'.
ACTION:
Tell the systems administrator.
----- amqccita.c : 4157 -------------------------------------------------------
12/20/17 10:03:48 - Process(28246212.1) User(mqm) Program(runmqchl)
Host(PRACEM) Installation(Installation1)
VRMF(8.0.0.7) QMgr(QM_PROD)

AMQ9999: Channel 'AIX.TO.USD' to host '10.59.158.179(1415)' ended
abnormally.

EXPLANATION:
The channel program running under process ID 28246212 for channel
'AIX.TO.SBIUSDC' ended abnormally. The host name is '10.59.158.179(1415)'; in
some cases the host name cannot be determined and so is shown as '????'.
ACTION:
Look at previous error messages for the channel program in the error logs to
determine the cause of the failure. Note that this message can be excluded
completely or suppressed by tuning the "ExcludeMessage" or "SuppressMessage"
attributes under the "QMErrorLog" stanza in qm.ini. Further information can be
found in the System Administration Guide.
----- amqrccca.c : 1090 -------------------------------------------------------




and sender channel defination is like this.

   USEDLQ(YES)                             USERID( )

i go through the some of articles with same errors, But those are related to Client and server setup.

Please suggest how to resolve.

Firstly, this caught my eye:

Quote:
dis chl(AIX.TO.USD)
4 : dis chl(AIX.TO.USD)
AMQ8414: Display Channel details.
CHANNEL(AIX.TO.SBIUSDC) CHLTYPE(SDR)

Note the difference, so what is the actual channel name, or have you obfuscated some details?

Secondly, setting a DISCINT of zero is a sure way of having problems diagnosing channel issues - is there a particular reason why the channel needs to run continuously?

Thirdly, is there a pattern in this, e.g. the channel runs for the same length of time before the communication break and retry? If so, is there a firewall between the two servers, and have you engaged your networks people to check their settings?

Thanks exerk,

Yes i obfuscated some details.

As per client requirement, We didn't implemented Channel triggering that's why i didn't mentioned DISCINT.

Channel is running for some time and going into retrying state, After some it is getting running. From our end ping is disabled, Is there any other option to check network is working fine.

What is the client's justification for wanting 24/7 channel running time?

You already stated that, so again, what is the pattern (if any) ?

By that I presume you mean non-MQ ping? And that wont necessarily show an issue anyway as the TTL will be magnitudes of order below a 24/7 channel run time.

Yes, it's a utility called EYNP - Engage Your Networks People!
