CSM What happens when real server fails?

[mruuth]

Hi,

What happens with connections to a failed real server? Are the "idle flow"-entry and sticky-entry been deleted and connection purged, so the enduser can establish a new connection to another server in the serverfarm? If not, what can I do to fix this? What are the differens between "Idle database" and "Sticky database" if I only use src IP-adress in sticky?

Regard

this is determine with the command 'failaction ...'.

By default, the CSM does nothing when a real goes down.

If you configure 'failaction purge' the csm will reset TCP connections and simply remove udp connections going to this server.

There is no such thing as idle database.

The sticky database has sticky entries that are removed from the database when idle longer than the idle timeout that you configured.

Gilles,

Thanks fo the reply.

Under vserver there is the Idle command and the Sticky command. What is the difference from the endusers view. You can clear connections and sticky entries but how do I clear Idle-entries?

the "idle" command refers to how long a connection that does not send any packets is kept alive.

The default is 3600 sec.

The sticky command ask you to specify a timeout.

This timeout is how long the CSM keeps the sticky entry in memory after the last connection was open.
