2.2. Failover

Post connection failover will be used if you are using an administration connection (such as what is used by AdminShell) or if the autoFailover connection property is set to true. Post connection failover works by sending a ping, at most every second, to test the connection prior to use. If the ping fails, a new instance will be selected prior to the operation being attempted.

This is not considered to be true transparent application failover because the client does not restart transactions or queries, nor will it recreate session scoped temporary tables.
