i have an ACE 4710 , version A3 2.0 , am i trying to reassign the TCP connection of one failed server to other operational servers in the server farm.The connection should be sticky to the server until the server fails. Is there any way ?
first, not all servers accept TCP connection to be reassigned to them...
This is because tcp requires 3-way handshake and keeps track of sequence/ack numbers.
Therefore, the servers need some way to exchange this information or to start in the middle.
On ace, we have 2 commands "failaction reassign" or "failaction purge".
The reassign is to simply move the connection to a backup server.
The purge is to kill the connection forcing the client to reopen a new one - this new connection will then be loadbalance to an active server.
