Welcome to the world of the poor shoemaker's skinny stepchild.
The RLPF package on the VM Download page (http://www.vm.ibm.com/download) provides a lot of useful tools to assuage the pain of running RACF. That's probably the best easily accessible tool available. And it helps you actually use the thing. You can always send the logs over to z/OS if you so choose: they don't cripple their RACF implementation so badly, and it'd probably make the auditors happy that they don't have to look in multiple places. In reviewing the RACF/VM pubs it appears that the racf report writer is functionally stabilized and is not recommended for use and the only other option is to post process the racf data. Are there any racf exception report tools available?
