Delete the RACF® database cache structure by removing RACF from data sharing mode. Remove RACF from data sharing mode with the RVARY NODATASHARE RACF command.

If the installation has defined RACF as a subsystem in the IEFSSNxx SYS1.PARMLIB member , the command can be issued from a z/OS® operator console, but the subsystem recognition character that the installation has defined through the command prefix facility will need to be used. Otherwise, the command must be issued from an authorized TSO/E user ID. For more information on IEFSSNxx, see z/OS MVS Initialization and Tuning Reference.

Use of the structure can be re-initiated when RACF is restored to data sharing mode with the RVARY DATASHARE RACF command.
