We are looking for a way to clear all inactive Client connections that are present on a queue.
And also Alerting when the number of inactive queue exceed a high water mark.
If the application team is not willing to do effecient disconnects and ect, from an middleware infrastructure support perpective what is the best way to remedy it ( Clear inactive Client connections). |

What did you mean by "inactive Client connections", exactly? How are you listing these? Thanks |

Using this in qm.ini
| Code: |
TCP: ; TCP/IP entries.
KeepAlive=Yes ; Switch KeepAlive on |
Can sometimes help with this problem. |

That would clean up orphaned connections where the client has truly left the building. But it won't squash "all inactive Client connections". If an inactive client connection means it could be a valid connection that is otherwise just not doing any MQ API calls.
The ClientIdle parameter would kill these types of connections. But note it is going after the client's connection to the QM, not the client's connection to the queue. So if one app has one connection to the QM, and it has 2 queues open, and only one queue connection is considered "inactive", ClientIdle won't differentiate. It will kill the connection to the QM only if any and all activity by that client is idle. I don't like ClientIdle.
JRome, define exactly what "an inactive Client connection" means to you.
