COMPAUTH control statement

Specifies whether to call the segment compression exit in supervisor state.

Tip: 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. Even if the input data for IMS HP Load is created in compressed (encrypted) format, it is recommended to specify COMPAUTH=YES to reduce performance degradation because IMS HP Load calls the encryption exit to decrypt segment data for internal processes in some conditions.

This control statement is optional. If you do not specify this control statement, COMPAUTH=NO is used.

NO
Specifies to call the segment compression exit in problem state.
YES
Specifies to call the segment compression exit in supervisor state.
Notes:
  • You must run this statement under program HPSRRC00, which is the IMS HP Load version of the region controller program.
  • Under IMS region controller (PGM=DFSRRC00), COMPAUTH=NO is assumed. If you specify COMPAUTH=YES, it will be ignored.
  • If you specify COMPAUTH=YES, you must APF-authorize the load module libraries that are specified on the STEPLIB DD.
  • If one or more libraries on the STEPLIB DD are not APF-authorized, IMS HP Load uses COMPAUTH=NO even if you specify COMPAUTH=YES.
Tip: The default value of the COMPAUTH control statement can be changed. For details, see Setting installation default options.
