| (average_number_of _conditional_access_entries × 17) +
| (average_number_of_libraries × 52)

communication, for each backup database add: 3248 + (4136
× number_of_database_buffers × 2)

Templates for RACF on OS/390 Release 4
The RACF database must have templates at the Security Server (RACF) Release 4
level in order for RACF to function properly. If a Security Server (RACF) Release 4
system is sharing the database with a lower-level system (RACF 1.9, RACF 1.9.2,
RACF 1.10, RACF 2.1, RACF 2.2, Security Server (RACF) Release 1, Security
Server (RACF) Release 2, or Security Server (RACF) Release 3), the lower-level
system is able to use the database with the Security Server (RACF) Release 4
templates. Use the IRRMIN00 utility to install the templates.
For more information, see
OS/390 Security Server (RACF) System Programmer's
Guide
and the program directory shipped with OS/390.
