The DATA_AREA_INFO view returns the values of data areas.

The values returned for the columns in the view are closely related to the values returned by the Retrieve Data Area (RTVDTAARA) CL command and the Retrieve Data Area (QWCRDTAA) API.

Authorization: The caller must have:
  • *EXECUTE authority to the library containing the data area, and
  • *USE authority to the data area.

For a DDM data area, the caller must be able to connect to the remote system.

To return information for a data area on a remote system, the caller must have:
  • *EXECUTE authority to the library containing the data area, and
