Data warehousing projects that require table spaces larger than one terabyte can use extended addressability for linear data sets. To do this, assign a data class with the extended addressability attribute to the data set when it is defined, and ensure that the following attributes are specified for the data class:

• Recorg = LS
• Data Set Name Type = Extended
• IF Extended = Required
• Extended Addressability = Yes

Then, ensure that your data class ACS routine for DB2® includes the following statement:

FILTLST DB2WH INCLUDE(DWH*.**) /* assuming these have a high level*/
                               /* qualifier of DWH...*/
SELECT
  WHEN (&DSN = &DB2WH)
    DO
      &DATACLAS = 'LDSEA'
    END
  OTHERWISE
