Hi all,

I m having MQ network problems..

following is the scenario.

MQver 5.3 CSD 12(server) , CSD11(client)

MQClient(windows) -----64KBpslink------->MQServer(aix)

Client makes a connections and keeps getting the messages from server
what happens is i get frequent MQRC 2009 , which is connection broken.
Then i have to re run the MQ clinet again and again..

What could be the reason for this connection broken error?
bt if i do a continuous ping from client to server , there is no error?

is it a problem w network or MQ?

can anyone shed some light on this?

thanks.

The only MQ reason the QM would drop the connection is if someone manually stopped your SVRCONN channel on the QM side, or if the MQ Admin set the ClientIdle parm. Or the Queue Manager or Listener were restarted since you last opened the queue.

Otherwise the underlying network connection yakked causing your MQ connection to go bad.

If your tcp/ip connection is unstable due to the network you are using it might be better to use a scenario like this:
MQClient(Win)--->MQServer(Win)-----64KBpslink------->MQServer(aix)

We have a case where this type of scenario (having a server in the same network as the clients) greatly decreased our connection broken returns.
It eases the burden on the unclosed svrconn problem on the server as well and did not add any significant time to the request/response pattern...

Enjoy
