All data volumes in a database instance are known collectively as the data area. The data area contains, amongst other things, the application data, the database catalog and the undo log entries of the database instance.
The size of the data area must not fall below 2,000 pages. There must also always be sufficient space in the data area to hold all the data that is created during database operations.
We recommend regular backups of the data in the data area.
