Specifies the name of the area for consistency checking.

Use Area consistency check to enable consistency checking for all record and index blocks in the specified area. When enabled, this option applies consistency checks to all index blocks and record blocks for record and index write operations. You can only specify one area with -AreaCheck. To check multiple areas, you must apply consistency checking to the entire database with Database consistency check (-DbCheck).

Area consistency check validates a block is still physically correct after an operation has been performed. For example, after an index key is inserted into an index block, the consistency check validates that the block still laid out correctly.

Area consistency checking can be enabled or disabled while your database is online with PROMON. See the Enable/disable block level consistency check on page 1051 for more information.

Area consistency check can be enabled for a single user client or for any offline utility. If the utility is read-only, such as DBANALYS, the -AreaCheck parameter is ignored. Online utilities determine whether or not to perform area consistency checking during execution based on the use of -AreaCheck at broker startup or by the enablement/disablement of the database consistency checking in PROMON.
