Protecting data sets that have single-qualifier data set names
If some of the data sets in your installation have names that consist of a single qualifier, you can still RACF-protect those data sets. To get RACF® protection for single-qualifier names, issue the SETROPTS command with the PREFIX operand. This command defines a high-level qualifier to be used as a prefix for single-qualifier names and activates the facility. Then, when RACF processes requests for the data set, RACF internally modifies single-qualifier names by adding the prefix, making the data set names acceptable to RACF routines.
In subsequent references to the profile, all RACF commands and the RACF report writer expect to see the prefix followed by a period and the single-level data set name. All SMF log records and all messages from RACF contain the RACF-modified version of the data set name.
real data set namescontinue to be the prefixed ones.
For more information on specifying the prefix, see Protecting data sets with single-qualifier names (PREFIX option).
