Hi,
I have a java application which connects to QueueManager and puts message in queue. After putting the message in queue I am closing the connection. After waiting for some time when no messages are available to put into queue I need to stop the server connection channel.
I have tried with PCF command to modify channel with KeepAliveInterval and HeartBeat, I am not ableto get what I am expecting.
Please help me how to stop the server connection channel, if the application is not using the channel for very long time.
Thanks in advance |

What are you expecting? More importantly what are you seeing that has led you to believe you need to do this? A svrconn channel should stop after a period of inactivity automatically.
Thought of course the status won't be stopped. But you knew that.

If the channel is still running after you have finished putting messages it appears that you are not actually disconnecting correctly in your application. Make sure you are CLOSING the queue and DISCONNECTING from the queue manager.

You mean the svrconn connection will be cleaned up automatically after a period if the client end has died (did not disconnect cleanly for some reason) ?
If the client end is still active (connected), a svrconn will stay running indefinitely.

And even if a client app has issued a specific disconnect() or otherwise disposed of a connection object, a JVM may actually keep the connection open and lying around for a while "just in case".
At least for as long as the JVM itself is alive. |

in addition, svrconn chzannels are sometimes shared between several applications. make sure that no other application is using this channel if you still see it "running" although you already disconnected.

I have standalone application that is using connection pooling implemented using commons-pool-1.3.jar. After putting the message the connection is returned to the pool. Now I got requirement to kill the entire pool if atleast one connection is not used for specific period of time.
I thought of killing the server connection channel, if no connection is used for specific time.
Please let me know options available to achive this.
Thanks in advance. |

You need to implement that at the pool level. Make sure to set min connections in pool to 0.
