When to Use

Use the LOAD Data Area option to:

• Restore a data area from a previous backup.

  Caution If you are using SQL to access data, restoring the areas of the DATA-DICT and Data Definition Directory (DDD) databases from current backups without restoring the Directory from a backup taken at the same time can result in loss of synchronization which is critical for SQL operations.

  If you are using CA Ideal, restore the Virtual Library System files from a backup that was taken at the same time as the backup of the Directory to assure synchronization. See the CA Ideal documentation for details.

  To retain synchronization, when restoring the Directory, perform forward recovery.

• Convert to a Unique Row Identifier (URI) format.
• Load a data area with data for a single table that is in EXTRACT (user) format. See EXTRACT (Extract Data Table) for more information.
• Null load a data area (cause all of the tables for this area to be marked usable, but empty) by loading one table with no input data.
• Reorganize a data area into Native Key sequence by table.

Important! Do not back up an Accounting Facility PRM table from one system and load it to another system.
