You can use automatic direction to maintain synchronization of RACF® database profiles that are already synchronized, but you must synchronize the profiles before you activate RRSF functions. You can do this synchronization manually, but it can be a time-consuming process. You can also run IRRDBU00 against the databases you want to synchronize, and use a program or REXX EXEC to compare the IRRDBU00 output for the databases and generate the commands needed to synchronize them. IBM® provides a sample REXX EXEC, DBSYNC, to help you do this. IBM does not support the DBSYNC EXEC. You can get this tool and others from the RACF home page.
