Perform a cold backup of the database
Prior to deploying the Portal for operational use, perform a cold backup of the Oracle database. This offline, cold backup simply means that you will physically copy or back up the files to another location. This cold backup will simplify the restore process, in the event of unanticipated data loss. With a cold backup, you simply have to restore the files and then import the most recent database export. In addition to this initial cold backup, you may consider performing a cold backup periodically--for example, after a significant software upgrade--to re-capture the database schema.
