As z/VM RACF is not sharing with z/OS anymore we need a z/VM face on RACF, remove irrelevant CLASSes

As z/VM RACF is not sharing with z/OS anymore we need a z/VM face on RACF, remove irrelevant CLASSes. IBM no longer permits the sharing of RACF DB's with z/OS and z/VM. So why have irrelevant RACF classes visible in z/VM? It is confusing when scan...

Remove all references to JES on output of RACF commands on z/VM

I consider this an incorrout defect. My idea is to remove any references to JES and additional z/OS references that have no bearing on the z/VM product. It is distracting and confusing to me a VM sysprog. As RACF is pulling apart on z/VM from the ...

Rise limits of Guest Coupling simulation support

We try to run zOS systems within a sysplex with large DB2 group buffer pool structures. These structures cannot be allocated if zOS is running in zVM because they are bigger than the given (undocumented) limit. The intention is virtualize systems ...

By putting the checks for OPERATIONS into the same environment as SPECIAL, AUDITOR an/or ROAUDITOR, the attribute can be (un)assigned dynamically without requiring the user to log in/out to refresh its assigned rights.

Unless a guest that logged on with the OPERATIONS is logged off, it retains that attribute and those rights until it has been logged off. This is a security vulnerability as there is a difference between RACF's contents and reality.It would also b...

Create new class B command to refresh stored DASD info without VARY OFF/ON the device

At present, for CP to see updated DASD info (like VOLSER, VTOC, etc), a device must be varied off/on to refresh the data. If the disk has been relabeled by a guest using full-pack minidisk, then the guest sees different information than a user wit...
