Shared database considerations

The use of the RVARY command becomes more complex when the RACF® database is shared with other systems. Generally, all systems must be synchronized with respect to the RACF database configuration.

If your database is being shared by several systems and one of the systems stops using the primary database by issuing RVARY SWITCH or RVARY INACTIVE, all of the systems sharing the database must do the same thing, or the results will be unpredictable. Therefore, if you issue the RVARY SWITCH or RVARY INACTIVE command on one system, you must issue it on every other system sharing the database.

Note: If RACF is enabled for sysplex communication, it propagates the RVARY SWITCH and RVARY INACTIVE commands for you from the system on which they are entered to the other members in the data sharing group. Therefore, you need to issue the command only once.

RACF also propagates the RVARY DATASHARE and RVARY NODATASHARE commands when enabled for sysplex communication.

See z/OS® Security Server RACF Command Language Reference for the complete syntax of RVARY.
