COMPAUTH control statement

The COMPAUTH control statement specifies whether to call the segment compression exit in supervisor state.

If you also specify the DECN control statement, this control statement is ignored because HSSR Engine does not call the segment compression exit.

If you use an encryption exit of InfoSphere® Guardium® Data Encryption for Db2® and IMS Databases as the segment compression exit, specifying COMPAUTH YES reduces performance degradation.
