Use the RACF® STARTED general resource class or the RACF Started Procedures Table, ICHRIN03, to associate DUMPSRV with a user id.
With the high-level qualifier of SYS1, the data sets are considered group data sets. You can assign CREATE group authority to the DUMPSRV user ID within that group.
See z/OS Security Server RACF System Programmer's Guide for information about the RACF STARTED general resource class, and the RACF Started Procedures Table. See z/OS Security Server RACF Security Administrator's Guide for information on using the RACF STARTED general resource class, and on controlling creation of new data sets.
