Readying Areas

The READY function informs CA IDMS which areas of the database will be accessed by the application program and in which of the following usage modes:

• RETRIEVAL- Records in the area can be retrieved only.
• UPDATE- Records in the area can be retrieved and updated.

When running under central version, specifying one of the following qualifiers controls concurrent use of the area by other applications:

• PROTECTED- Prevents other applications from updating data.
• EXCLUSIVE- Prevents other applications from accessing the area for both retrieval and update operations.

If neither PROTECTED nor EXCLUSIVE is specified, the system assumes that the area is shared and concurrent access of any kind is acceptable.
