Sharing a database with sysplex communication in data sharing mode
z/OS Security Server RACF System Programmer's Guide
When RACF® enters data sharing mode, all members of the sysplex change modes at the same time. If you want to use data sharing mode, all systems sharing the database must be members of the same sysplex. Before RACF can enter data sharing mode, the following additional requirements must be met:
If you have z/OS systems that need to use the same security data, but are not all members of the same sysplex, you can give a system outside of a sysplex its own copy of the RACF database used by the sysplex, and use automatic direction to keep the databases synchronized. See Overview of the RRSF function for information on automatic direction.
