Oracle Fusion Middleware and high availability....

Im currently on an Oracle High Availibility course and picking up a few gems which I thought Id share...

  • J2EE
    • When setting up J2EE state clustering you have three communication approaches for replicating state ;
      • Multicast
      • Peer-to-Peer
      • Database

        Generally Multicast is the easiest to setup and gives the best out of the box performance however with some tuning peer to peer is more efficient.

        We now also have a database option where the state is saved to an Oracle database. This approach is the most reliable, however there is obviously a performance penalty for this.
