PROCESS

SYS1

specifies that DFSMSdss allows data sets with a high-level qualifier of SYS1 to be dumped and that SYS1 data sets can be deleted and uncataloged. SYS1.VVDS and SYS1.VTOCIX data sets can be physically, but not logically, dumped. SYS1.VVDS and SYS1.VTOCIX data sets cannot be deleted or uncataloged. To specify PROCESS(SYS1), RACF® authorization may be required.
