e. In the Available field of the Migration Configuration section, select the

machines to which to allow migration and click the right arrow.

f. Choose the Automatic Server Migration Enabled option. This enables Node

Manager to start a failed server on the target node automatically.

g. Click Save.

h. Restart the Administration Server, managed servers, and Node Manager. 17. Test server migration for the new server. To test migration, perform the following steps from the node where you added the new server: ■ Abruptly stop the WLS_SOAn managed server. To do this, run kill -9 pid on the PID of the managed server. You can identify the PID of the node using the following command: ps -ef | grep WLS_SOAn ■ Watch the Node Manager Console for a message indicating that WLS_SOA1s floating IP has been disabled. ■ Wait for Node Manager to attempt a second restart of WLS_SOAn. Node Manager waits for a fence period of 30 seconds before trying this restart. ■ Once Node Manager restarts the server, stop it again. Node Manager should log a message indicating that the server will not be restarted again locally.

Table 12–1 lists the static artifacts to back up in the 11g Oracle ECM enterprise deployment. Note: Specify the least-loaded machine as the migration target for the new server. The required capacity planning must be completed so that this node has enough available resources to sustain an additional managed server. Note: After a server is migrated, to fail it back to its original node or machine, stop the managed server from the Oracle WebLogic Administration Console and then start it again. The appropriate Node Manager will start the managed server on the machine to which it was originally assigned.
