REN Server Failover

Although the REN server is integrated into an application server domain, it is not a standard PeopleTools server process (it has no database connection) and therefore has a separate failover mechanism. Two scenarios exist for failure recovery:

• For a standalone REN server, Oracle Tuxedo restarts the server if it fails.

  MCF servers and consoles reconnect to the REN server. However, any active browser sessions (such as MCF chat) are interrupted until a connection can be reestablished between the chat console and the restarted REN server.

• For clustered REN servers, each REN server in the cluster is a peer that mirrors the current state.

  This configuration has two advantages over a standalone REN server:

  • Clustered REN servers guard against hardware failure (provided that the clustered REN servers are on different host machines).

  • Active browser sessions are not lost.
