The VP390 task or the task’s owning user requires a z/OS UNIX System Services (USS) segment. Because USS segments are associated with RACF-defined user IDs, you should add an identifying entry for VP390 to a RACF class to meet the USS requirement.
This addition allows the VP390 to run as a started task. If the VP390 is to be run as a submitted job, enter the user ID on the JOB card of the startup job.
To add an entry to the RACF class, follow these steps:
RACF allows the started procedures table to contain a generic entry, indicated by an asterisk (* ) in the procedure-name field. When searching the table for a procedure-name match, if RACF finds a procedure name of "*" as the last entry in the table and the procedure name was not specifically matched by any other entry in the table, RACF uses the "*" entry as a match for the procedure. This procedure is documented in the IBM Security Server (RACF) System Programmer's Guide.
