Starting DEDBs and DEDB areas

You can start access to a DEDB or start the scheduling of application programs against a DEDB at the database level or the area level.

The database-level commands include the type-1 command /START DB and the type-2 command UPDATE DB START(ACCESS).

The area-level commands include the type-1 command /START AREA and the type-2 command UPDATE AREA START(ACCESS). The /START AREA command does not open areas unless you have specified them as PREOPEN or PRELOAD areas.

You can start all areas of a DEDB at once by using the AREA(*) parameter of the type-2 command UPDATE DB START(ACCESS). The AREA(*) parameter is useful if you have stopped access to a DEDB at the database-level by issuing the type-1 command /DBRECOVERY DB or the type-2 command UPDATE DB STOP(ACCESS). Note that specifying an area name, for example AREA(area_name), is invalid.

You can use the AREA(*) parameter with the SET(ACCESS) parameter of the type-2 command UPDATE DB START(ACCESS) to start all areas at once and to change the access type for the DEDB at the same time.

You can also open DEDB areas when you start them by specifying the OPTION(OPEN) keyword on the either of the type-2 commands UPDATE AREA START(ACCESS) or UPDATE DB START(ACCESS).
