You must have two version 12.0 or later Adaptive Servers configured for failover.
You must use jConnect version 5.2, or later. Earlier driver versions do not support this feature.
Only changes that were committed to the database before failover are retained when the client fails over.
You must set the REQUEST_HA_SESSION jConnect connection property to true (see “Setting connection properties”).
jConnect event notification does not work when failover occurs. See “Using event notification”.
Close all statements when they are no longer used. jConnect stores information on statements to enable failover. If you do not close statements, you will experience memory leaks.
