The 1994 introduction of the Coupling Facility (CF) introduced a new era in mainframe processing. From day one, RACF has allowed clients to utilize the CF as a high-performance cache for information in the RACF database.

This session explores RACF’s use of sysplex services, from ENF signals to help manage cache purging to the RACF’s DATASHARING mode, which allows the use of the CF as a high-speed cache for the RACF data base.

Session was done back at GSE 2020 and is similar to this session: https://public.dhe.ibm.com/eserver/zseries/zos/racf/pdf/rugone_2021_10_14_racf_and_the_parallel_sysplex.pdf
