Recovering from a WebLogic Server Failure
The following sections describe how to restart or replace a WebLogic Server instance
in the event of a system failure, and provide programming considerations for
gracefully terminating a JMS application following such an event.

recovery:
n Restart the failed server instance.
n Start up a new server instance using the same IP address as the failed server.
n Start up a new server instance using a different IP address than the failed server.
To restart the failed server instance or start up a new server instance using the same IP
address as the failed server, boot the server and start the server processes, as described
in “Starting and Stopping WebLogic Servers” on page 2-1.
To start up a new server instance using a different IP address than the failed server:
1. Update the Domain Name Service (DNS) so that the server alias references the new
IP address.
2. Boot the server and start the server processes, as described in “Starting and
Stopping WebLogic Servers” on page 2-1
3. Optionally, perform one or more of the tasks listed in the following table:
