18.2.10 Recovering a Database

If your database that contains your metadata repository, including the MDS Repository, is corrupted, you can recover it using RMAN. You can recover the database at the desired granularity, either a full recovery or a tablespace recovery. For best results, recover the database to the most current state, using point-in-time recovery if the database is configured in Archive Log Mode. This ensures that the latest data is recovered. For example: rman restore database; rman recover database; See Appendix D for the schemas used by each component. For detailed steps, see the Oracle Database Backup and Recovery Users Guide, which is available at: http:www.oracle.comtechnetworkdatabaseenterprise-editiondocumenta tionindex.html

To recover an Oracle WebLogic Server domain: 1. Stop all relevant processes. That is, stop all processes that are related to the domain, such as the Administration Server and Managed Servers. For example, stop the Administration Server: DOMAIN_HOMEbinstopWeblogic.sh username password [admin_url] 2. Recover the domain directory from backup: cd DOMAIN_HOME UNIX tar -xf domain_backup_092010.tar Windows jar xtf domain_backup_092010.jar Note: When you are recovering in the case of loss of host, you must restore the files using the same path as on the original host.
