Connection details

There's end-to-end ssl connectivity from user to SAP servers through F5. It's configured with source IP address as affinity method. The sessions were getting timed out prematurely when left idle. I increased the persistence timeout and it resolved the issue.

 

What I do not understand is as follows :- 1. Why increasing the time out settings for idle time out and configuring keep-alive did not maintain the session ? 2. Now when the user session is maintained for over an half-an-hour, I do not see it's connection logs on F5 tmsh using show sys connection command.

    It looks like you're confusing persistence (Which maintains the affinity between client and pool member over multiple connections) and connections themselves.

     

    Connection entries will only be shown while there is an active connection. The persistence is separate and just ensures that that NEXT connection will be persistent to the same pool member.
