I have a server connection channel between 2 servers, one being the application and the other being the MQ server.
After 1 hr of being idle, the channel is getting disconnected automatically. with the below error:
05/23/09 09:00:21
AMQ9213: A communications error for TCP/IP occurred.
EXPLANATION:
An unexpected error occurred in communications.
ACTION:
The return code from the TCP/IP(select) [TIMEOUT] 20 seconds call was 11
(X'B'). Record these values and tell the systems administrator.
Here are the channel properties:
display channel(PROFILE.CLNTCONN.CHL)
2 : display channel(PROFILE.CLNTCONN.CHL)
AMQ8414: Display Channel details.
CHANNEL(XXX.CLNTCONN.CHL) CHLTYPE(SVRCONN)
TRPTYPE(TCP) DESCR( )
SCYEXIT( ) MAXMSGL(4194304)
SCYDATA( ) HBINT(0)
SSLCIPH( ) SSLCAUTH(REQUIRED)
KAINT(AUTO) MCAUSER( )
ALTDATE(2009-05-25) ALTTIME(11.08.54)
SSLPEER()
SENDEXIT( )
RCVEXIT( )
SENDDATA( )
RCVDATA( )

Something like a firewall closing the connection. Speak to your network people to see if anything behaves like that.
You'll also find a number of discussions in here on the subject, which you may find informative.

How does this tie up with:

I'm also confused by this:

a) Was there a question here?
b) If you'd disconnected the connection, why are you apparently surprised by an error message saying "CONNECTION_BROKEN"?

| in the first case I manually disconnected the connection, but in the second instance, the connection got automatically disconnected after 1hr. I had to reconnect after every 1 hr. |

What system hanged? MQ? The o/s? What error was logged?

These errors are saying that connectivity between your application and Qmgr got disrupted.
Have you checked that your firewall setup is fine?

Do you mean that the client o/s got hanged? Or just the client application?

Where did you find these errors? I'm guessing on the client platform...

I meant that the client application got hanged, and later i found the error messages in the same client machine error logs.
here is the new error msg recorded:
05/27/09 20:09:20
AMQ9209: Connection to host '172.25.134.64' closed.
EXPLANATION:
An error occurred receiving data from '172.25.134.64' over TCP/IP. The
connection to the remote host has unexpectedly terminated.
ACTION:
Tell the systems administrator.

So you've checked, and you're absolutely, completely certain that there's nothing in your network that closes a connection after an hour? Not
| Quote: |
| "I've checked and it can't be ---- because it only disconnects inactive connections after an hour and mine is active |
but nothing that closes connections? You're certain?
Because if that's the case, and you're certain that's the case, you should raise a PMR because the channel is incorrectly determining connection status.

Ah - I'd missed the fact that you were using v5.3. My bad.
So no PMR then.
