data is updated on the target machine. When your source machine is ready to come back online, the data

is no longer current and must be updated with the new data on the target machine.

1. Verify that your source machine is not connected to the network. If it is, disconnect it.

2. Resolve the source machine problem that caused the failure

NOTE: If you must rebuild your hard drive, continue with step 3.

If you do not need to rebuild your hard drive, verify that the Storage Mirroring connection on the source

has been disconnected (right-click the connection in the Storage Mirroring Management Console and

select Disconnect) and then continue with step 4.

3. If you must rebuild your hard drive, complete the following. If you do not need to

rebuild your hard drive, skip this step and continue with step 4.

4. Install Windows. Since your source machine is not connected to the network, go ahead and use the

source’s original name and IP address.

d. Install Storage Mirroring using the installation defaults.

NOTE: Verify that the transactional applications option is selected on the Storage Mirroring

Optimizations screen since Oracle is a transactional database application. See the Storage Mirroring

Getting Started guide for further details.

a. In Control Panel, Administrative Tools, Services, double-click the Oracle service.

b. Click the General tab.

c. Select Manual from the Startup type drop-down list and click OK.

Depending on the type of failure, your services may be set to manual startup but could still be running.

Stop your Oracle services and set them to manual.

7. Select Start, Programs, Storage Mirroring Failover Control Center.
