The RACF remote sharing facility is built on the concept of a network of RRSF nodes. An RRSF node is an MVS™ system image, or several MVS system images sharing a RACF® database, that has been defined as an RRSF node to RACF. Before you can use the functions provided by RRSF, you must configure your MVS system images into a network of RRSF nodes. For detailed information see The RRSF network and Configuring an RRSF network.
