ACE feature

Guys,

I have a question and would like your help on it.

If I have a server farm with two real servers in it and I want to take out one server out for maintenance or whatever , is that possible to do so without disconnecting the existing sessions connected to that server?

Hi,

You can shut down a real server gracefully by using the no inservice command in either real server host or real server redirect configuration mode. This command causes the ACE to tear down all non-TCP connections to the server. For TCP connections, existing flows are allowed to complete before the ACE takes the real server out of service. No new connections are allowed.

Hi Siva,

I have a question please....... I have tested the "inservice standby " command since I am using sticky , but I still see connections hitting this server !!!! which shouldn't be the case right ??

With sticky it works in a different way, you would have to manually clear the session existing on that one rserver..

Does that mean the users connected will be affected??
