8-8 Oracle Fusion Middleware 2 Day Administration Guide
For Oracle Portal, Oracle Reports, Oracle Forms Services, and Oracle Business Intelligence Discoverer, you must back up the Managed Server domain directories,
in addition to the Administration Server domain.
3.
Back up the Oracle instance home. This backs up the system components, such as Oracle HTTP Server. For example:
tar -cf instance_home_backup_092010.tar ORACLE_INSTANCE
4.
Backup the database repositories using the Oracle Recovery Manager RMAN. For detailed steps, see the Oracle Database Backup and Recovery Users Guide, which
is available at:
http:www.oracle.comtechnologydocumentationdatabase.html
5.
Create a record of your Oracle Fusion Middleware environment. See Section 8.4
.
8.3 Recovering After Data Loss, Corruption, or Media Failure
This section describes recovery strategies for outages that involve actual data loss or corruption, or media failure where the disk cannot be restored. This type of failure
requires some type of data restoration before the Oracle Fusion Middleware environment can be restarted and continue with normal processing. It contains the
following topics:
■
Recovering a Middleware Home
■
Recovering an Oracle WebLogic Server Domain
■
Recovering the Administration Server Configuration
■
Recovering a Managed Server
■
Recovering an Oracle Home
■
Recovering an Oracle Instance
■
Recovering Components For information about recovering after the loss of a host, see Recovery After Loss of
Host in the Oracle Fusion Middleware Administrators Guide.
8.3.1 Recovering a Middleware Home
You can recover a Middleware home that was corrupted or from which files were deleted.
To recover a Middleware home:
1.
Stop all relevant processes. That is, stop all processes that are related to the domain, such as the Administration Server, Node Manager, and Managed Servers.
For example, to stop the Administration Server on Linux:
DOMAIN_HOME binstopWeblogic.sh username password [admin_url]
2.
Recover the Middleware home directory from backup. For example:
cd MW_HOME UNIX tar -xf mw_home_backup_092010.tar
Windows jar xtf mw_home_backup_092010.jar
3.
Start all relevant processes. That is, start all processes that run in that Middleware home. For example, to start the Administration Server:
Backing Up and Recovering Oracle Fusion Middleware 8-9
DOMAIN_HOME binstartWebLogic.sh -Dweblogic.management.username=username
-Dweblogic.management.password=password -Dweblogic.system.StoreBootIdentity=true
8.3.2 Recovering an Oracle WebLogic Server Domain
You can recover an Oracle WebLogic Server domain that was corrupted or deleted from the file system.
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_HOME binstopWeblogic.sh username password [admin_url]
2.
Recover the domain directory from backup. For example:
cd MW_HOMEuser_projectsdomainsdomain_name UNIX tar -xf domain_backup_092010.tar
Windows jar xtf domain_backup_092010.jar
3.
Start all relevant processes. That is, start all processes that are related to the domain. For example, start the Administration Server:
DOMAIN_HOME binstartWebLogic.sh -Dweblogic.management.username=username
-Dweblogic.management.password=password -Dweblogic.system.StoreBootIdentity=true
4.
If you cannot start the Administration Server, recover it, as described in Section 8.3.3
.
5.
If you cannot start a Managed Server, recover it, as described in Section 8.3.4
.
