Applications are connected to MQ through client channels. Once in a while we are experiencing TCP/IP errors.. At this time, applications are getting disconnected from qmgrs.
------------------------------------------------------
AMQ9208: Error on receive from host myhost (10.11.12.13).

EXPLANATION:
An error occurred receiving data from myhost (10.11.12.13) over TCP/IP.
This may be due to a communications failure.
ACTION:
The return code from the TCP/IP (read) call was 229 (X'E5'). Record these
values and tell the systems administrator.
-------------------------------------------------------

mqversion:
Version: 530.7 CSD07
OS:
HP-UX B.11.11 U 9000/800

Any hints on what to do pls?

Thanks

Hi,

i would start out by checking how 'once in while' these errors are occurring. Do they coincide with any activity from the client end? Are they regularly spaced out?

What time of day etc do you get these errors.

They could also be related to network infrastructure - are you confident of your network and can dismiss it as a source of the problem?

Good luck!

This link may help you, it gives you a list of the TCP/IP return codes on the UNIX platforms.

http://publib.boulder.ibm.com/infocenter/db2v7luw/index.jsp?topic=/com.ibm.db2v7.doc/db2m0/db2tcp.htm

Looks like 229 is ENETUNREACH (No route to the network is available). Certainly sounds like there is a routing issue - any chance any of the servers in the route is having a problem during these times?

I would definitely take this up with your network folks.

Cheers
Steve

Steve,

Thank you thank you thank you for this link. I never seem to be able to find a TCP error code when I need it.

It's not impossible, even without that link. This gets it: http://www.google.co.uk/search?hl=en&q=229+errno+HP-UX

And so should this (haven't been able to get onto an HP-UX system to check, though)
Code:
find /usr/include -type f -exec grep 229 {} \; -print
