OCS 2007 - Presence Issue with LB F5

Hello,

 

 

We have setup a MOCS 2007 R2 platform in our environment since 6 month and this platform work perfeclty with the load balancer BIG IP F5 execpt one issue: the presence information for a user is not change when he unplug his network cable or disable his wifi connection

 

 

For example :

 

1/ When we are connected directly to the MOCS server, we received this error message after 30s when a user is disconnecting from MOCS:

 

"This message was not delivered to because one or more recipients are offline"

 

 

In this case the presence of the user is change to offline after 30s.

 

 

2/ If we used the load balancer we received this error message after 60s when a user is disconnecting from MOCS:

 

"This message was not delivered to because there was no response from the server"

 

 

In this case the presence of the user is change to offline after 300s and this is not acceptable !!!!

 

 

Please help us for this topic.

    Hi,

     

     

    the 300 seconds suggests that this is related to the idle timeout on the TCP profile, so I guess this is related to the LTM keeping the connection open for that time period and only once closed does your server react.

     

     

    So the place to start would be creating your own TCP profile and using a shorter idle timeout, then apply this to the "Protocol Profile (Server)" on the relevant Virtual Server.

     

     

    I hope this helps.
