Modifying security options
Commands to modify security options for RACF® are described.
Use the /MODIFY PREPARE RACF, /DISPLAY MODIFY, and /MODIFY COMMIT commands to reinitialize RACF information if you are not using a RACF data space. If you are using a RACF data space, use the RACF SETROPTS RACLIST command rather than the IMS /MODIFY command.
Use the /SECURE APPC command to control the RACF security level for input from LU 6.2 devices. Use the /DISPLAY APPC command to show the security level that is currently in effect. When IMS starts, the default is full security.
Use the /SECURE OTMA command to control the RACF security level for input from specified OTMA clients or for the entire OTMA z/OS® cross-system coupling facility (XCF) group. Use the /DISPLAY OTMA command to show the security level that is currently in effect. When IMS starts, the default is full security.
Use the /SECURE OTMA REFRESH command to refresh security information cached in online memory after making a RACF change to a specific user ID. Cached OTMA security information can be refreshed globally by the OTMA TMEMBER, or by user ID, without impacting other cached user IDs.
