| We have a JMS client on JBOSS connecting to our MQ server .If the system is idle i.e(no transfer of messages) for 30 or 40 minutes the connection drops.Is ther any configuration setting in MQ or JMS where I can keep the connection up and running.Any suggestion is greatly appreciated. |

Have you investigated what it is that is dropping the connection? Maybe it's JBOSS, maybe it's MQ, maybe it's the application, maybe it's... the firewall...
It won't do a lot of good to adjust MQ if it's JBOSS that's dropping the connection, and etc.

I am sure the application is not closing the connection.To keep the connection up and running I have written a MQ put program which connects to MQ server every one hour and this keeps the channel up and running.We are using the default "SYSTEM.DEF.SVRCONN" channel.
I do not want to use the MQ put program as we want to deploy the code in to production.As you suggested I will check the firewall setting. |

Also check to see if the MQ Admin set the ClientIdle parameter as that can shutdown valid but quiet MQ Client connections.

You should be using a new SVRCONN channel specific to your app.

We are not using ClientIdle parameter but using KeepAlive ="YES".
Is it recommended not to use default SYSTEM.DEF.SVRCONN channel.Do we have any issues by using this channel. |

Yes.
Because you can't tell who's using it.
