RACF® allows you to control the use of the MVS™ commands SETPROG and SET PROG, and the use of the CSVDYLPA macro, for processing Dynamic LPA.

The SETPROG command allows a user to add modules to the LPA following IPL, delete modules from the LPA following IPL, and set threshold values for minimum amounts of CSA storage that still must be available after an ADD operation. SET PROG allows a user to activate the PROGxx member of SYS1.PARMLIB that contains definitions for controlling Dynamic LPA. CSVDYLPA is an authorized MVS macro that allows you to perform the dynamic LPA processing from an application program.
