    The IBM RACF® remote sharing facility (RRSF) allows RACF to communicate with other IBM z/OS® systems that use RACF, allowing you to maintain remote RACF databases. RRSF support for the security administrator provides these benefits:

    • Administration of RACF databases from anywhere in the RRSF network
    • Creation of User ID associations for password and password phrase synchronization
    • Automatic synchronization of databases

    Before to z/OS V1R13, RRSF only supported the APPC protocol. With z/OS release V1R13, TCP/IP can be used to extend the RACF Remote Sharing Facility (RRSF) functionality to a network of RRSF nodes capable of communicating over the TCP/IP protocol. Using TCP/IP connections for RRSF nodes provides advantages over APPC such as improved security, including stronger encryption levels.

    This IBM® Redbooks® publication addresses the issue of implementing a new RRSF network using the TCP/IP protocol. It covers planning, implementation, and operational issues for deploying RRSF using TCP/IP. In addition, It addresses migration of an RRSF network from APPC to TCP/IP, including in-depth examples of the migration process.
