Shared RACF database z/OS Security Server RACF System Programmer's Guide SA23-2287-00 |

RACF® is designed so that its database can be shared between processor complexes while data integrity is maintained. Because of the need to serialize RACF database processing, there might be some I/O contention. However, if your installation does not share the database, you optimize performance if you place the RACF database on a non-shared device. See also Using the global resource serialization function. |
