Restoring databases

A single IMC system supports only manual restoration of the databases.

Manual restoration immediately replaces all database files with the backup database files. It supports the following types:

• Locally Restore—Applicable to scenarios where all backup files are saved on the master server.

• Remotely Restore—Applicable to scenarios where backup files are saved on the master and subordinate servers.

As a best practice, restore database files for the IMC platform and service components together. If you restore only some of the database files, data loss or inconsistency might occur.

Make sure IMC has been started at least once after installation before you restore the IMC databases.

To perform a manual restoration:

1. On the Environment tab, click Restore.

   The Restoration Type dialog box opens, as shown in Figure 94.

2. Perform one of the following operations:

   If all backup files are saved on the master server:

   1. Click Locally Restore.

      The Confirm dialog box opens, as shown in Figure 95.

   2. Click Yes.

      The Select the data file to be restored dialog box opens.

   3. Select database files to be restored, and then click OK.

      A confirmation dialog box opens.

If backup files are saved on the master and subordinate servers:

1. Click Yes.

   The system starts restoring the database files.

After the local or remote restoration is complete, the system displays a restoration success message.

1. Click OK.

   The IMC service will be automatically started.

   	NOTE: Before remote restoration, you must configure automatic backup and restoration parameters. Then DBMan can automatically locate running configuration files and database files. During the restoration process, DBMan shuts down and restarts IMC and the database service.
