Regarding user connection: if a user is connected to node2 of a 2 node cluster, and node2 dies, the user can automatically be reconnected to node1, if the user was in the middle of a query (select), that query can be restarted. Additionally,when the user connects to node2 under normal operating circumstances, the user can be pre-connected to node1 ahead of time.

Regarding load balancing -- there is *some* going on. Oracle8i will be better. It's possible for a user to be connected to the least busy system, but if I were you I'd speak with Oracle about this, because you may not want to do this based on your application.

Regarding high availability: the WHOLE IDEA behind Oracle Parallel Server is simultaneous access to the database by more than one node. Therefore, if node2 crashes, users on node1 continue accessing the database. Received on Thu Jan 28 1999 - 18:18:59 CST
