Rule Based Persistence & Fail Over

Unfortunately, that's the problem with using the node command. It does not have any knowledge of the status. This is one big reason we now recommend using the pool member command. This takes into account status of the pool member. So, use this command instead of the node command:

   pool admin member [getfield $entry " " 2] [TCP::local_port]

You will also want to add a LB_FAILED event so you can issue the command "LB::reselect pool admin" which will then reselect a new member of the pool based on a load-balancing decision (instead of using the supplied member).

when LB_FAILED {
   LB::reselect pool admin
}
