Restoring the RASD

If the RASD becomes corrupt (for example, because of a device failure), you can restore the database from the most recent backup files.

The Replication Agent retrieves the RASD backup files from the directory identified by the rasd_backup_dir configuration parameter. See the Replication Agent Reference Manual for more information about the rasd_backup_dir parameter.

Note: To restore the RASD, the Replication Agent instance must be in Admin state.

To restore the RASD from backup files:

Log in to the Replication Agent instance with the administrator login.
Get the current status of the Replication Agent instance:
```
ra_status
```
If the Replication Agent is in Admin state, skip this step and go to step 4.

If the Replication Agent is in Replicating state:
1. Suspend replication for the Replication Agent instance:
```
suspend
```
2. Verify that the Replication Agent instance is in Admin state:
```
ra_status
```
Restore the RASD:
```
rasd_restore backup_directory
```
where backup_directory contains the backup you want to restore (for example, 2012-07-04_14.21.34). If you issue rasd_restore without any parameters, only the most recent backup is restored.

After the restore operation completes successfully, the Replication Agent returns a message to confirm that the RASD restore was successful.

If the Replication Agent cannot find the directory identified in the rasd_backup_dir parameter, or if it cannot read the RASD backup files in that directory (for example, because of a permission problem), it returns an error. You must correct the cause of the error to restore the RASD.
Resume replication for the Replication Agent instance:
```
resume
```
