Page 131 of the CA Cleanup manual section titled "Tracking File Considerations in a Multiple LPAR Environment for CA Cleanup for Top Secret" gives 3 scenarios concerning sharing but leaves one out. Shared CA Top Secret Security File with CPF enabled.
SYSTEM A and B share a security file.
SYSTEM C and D share a security file.
SYSTEM A and B CPF's to C and D.
SYSTEM C and D CPF's to A and B.
In that type of environment, SYSTEM A and B who share a security file would also share a Cleanup Tracking File.
SYSTEM C and D who share a security file would also share their own Cleanup Tracking File.
If you need to run a Cleanup report for A and/or B, you would point to their shared Cleanup Tracking File. The same would go for C and D.
If you need a Cleanup report for all D SYSTEMs in one report, you would have SYSTEM A and B shared Cleanup Tracking File ***AND*** SYSTEM C and D shared Cleanup Tracking File as input for the Cleanup report.
