The z/OS® system administrator might restrict access to this interface by defining the RACF® (or equivalent external security manager product) resource IST.NETMGMT.sysname.SNAMGMT in the SERVAUTH class (sysname represents the MVS™ system name where the interface is being invoked).

For applications that use the interface, the MVS user ID is permitted to the defined resource. If the resource is not defined, then only superusers (users permitted to BPX.SUPERUSER resource in the FACILITY class) are permitted to it. If you are developing a feature for a product to be used by other parties, include instructions in your documentation indicating that either administrators must define and give appropriate permission to the given security resource to use that feature, or you must run your program as superuser.
