Hi
I am connecting to MQ server by using MQ client. MQ client is on windows and MQ server is on linux server and MQ client version is 7.5.02 and MQ server version is 7.5.0.5. I configured the DISCINT to the server connection channel to 300 sec but MQ client channel is not disconnecting after 300 sec and also i tried with ClientIdle in the configuration file.Please help me how to disconnect the unused client connection channels..Thanks in Advance |

I don't think he is disconnecting his clients. Hence looking for client idle...

If the client is sitting in GET WITH WAIT, it will not go idle.

Look at the source-code of the offending app. Does it (ever) issue an MQDISC? Or does it loop - forever waiting for a message to arrive?

When you start the amqsput or amqsputc program, it will wait for you to type the application data payload on STDIN. After typing the application data payload, press the ENTER key to cause the message to be put to the queue.
Press the ENTER key on a null line to end the program. As long as the program is executing (waiting for you to type the next message), the connection will remain active.

| Thanks bruce .I am facing problem with reaching to the maximum channels.what i observed is that most of the connections from application.They are connecting thrrough cleint connection channel.I think application team is not closing the connection after putting PAYLOADS. if i set the DISCINT interval to 300 to the server connection channel then is it fine or please suggest me what other changes i have to do. |

go kick the App Dev team (and keep on kicking) until they fix their applications.

Seems to me like in his test case, the client channel should end after 300 seconds.

DISCINT(integer)
For SVRCONN channels using the TCP protocol, DISCINT has a different interpretation. It is the minimum time in seconds for which the SVRCONN instance remains active without any communication from its partner client. A value of zero disables this disconnect processing. The SVRCONN inactivity interval applies only between WebSphere MQ API calls from a client, so no client is disconnected during an extended MQGET with wait call. This attribute is ignored for SVRCONN channels using protocols other than TCP. |

Yes... So an application sitting in a GET with WAIT will not be disconnected.

Thanks for your replies Peter,Jeff and bruce.I gone through the link provided. I didn't understand this point.Please explain me
The SVRCONN inactivity interval applies only between WebSphere MQ API calls from a client, so no client is disconnected during an extended MQGET with wait call
and i am using amqsputc to test my changes.Application team is not ready to make changes at thier side.Please confirm me is it fine with my changes. |

Please execute the amqsputc program again. Post here the complete interaction between you and the shell (window).
When the channel hangs, do a DISPLAY CHSTATUS for the offending channel; and post the results here.
