Special Program Properties

Special program properties are a requirement. They must be assigned to the system for the program MSMCAUX named on the EXEC PGM= JCL card in the MSMCAUX PROC.

MSMCAUX must be defined in the SCHEDxx member of SYS1.PARMLIB to execute in storage protect key 4.

To define MSMCAUX to execute in storage protect key 4, use the following statement:

PPT PGMNAME(MSMCAUX) KEY(4) SYST PRIV

Note: Special program properties are only assigned to programs that are retrieved from an APF-authorized library concatenation. All MSMCAUX PROC STEPLIB data sets must be properly defined in the APF library list.

For more information about the definition of special program properties, see the IBM Initialization and Tuning Reference.
