Recovering Your Environment 18-19 3. Start all relevant processes. That is, start all processes that are related to the domain. For example, start the Administration Server: DOMAIN_HOMEbinstartWebLogic.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 18.3.2 . 5. If you cannot start a Managed Server, recover it, as described in Section 18.3.3 .

18.3.2 Recovering After Loss of Administration Server Host

If you lose a host that contains the Administration Server, you can recover it to the same host or a different host, as described in the following topics: ■ Recovering the Administration Server to the Same Host ■ Recovering the Administration Server to a Different Host

18.3.2.1 Recovering the Administration Server to the Same Host

In this scenario, you recover the Administration Server either to the same host after the operating system has been reinstalled or to a new host that has the same host name. For example, the Administration Server is running on Host A and the Managed Server is running on Host B. Host A has failed for some reason and the Administration Server must be recovered. To recover the Administration Server to the same host: 1. Recover the file system. For example, recover the domain containing the Administration Server, as described in Section 18.3.1 . 2. Attempt to start the Administration Server. For example: DOMAIN_HOMEbinstartWebLogic.sh -Dweblogic.management.username=username -Dweblogic.management.password=password -Dweblogic.system.StoreBootIdentity=true If the Administration Server starts, you do not need to take any further steps. 3. If the Administration Server fails to start, take the following steps on Host A: a. 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, to stop the Administration Server on Linux: DOMAIN_HOMEbinstopWeblogic.sh username password [admin_url] b. Recover the Middleware home, if needed: tar -xf mw_home_backup_092010.tar c. If the domain directory does not reside in the Middleware home, recover the domain directory from backup: cd DOMAIN_HOME tar -xf domain_backup_092010.tar d. Start the Administration Server. For example: DOMAIN_HOMEbinstartWebLogic.sh -Dweblogic.management.username=username -Dweblogic.management.password=password
