The real-time NMI performs the following actions to verify the authorization of an application when the application connects to the real-time interface:

• If a multilevel secure (MLS) environment is active, the real-time interface resource profile must be defined and the user ID that is associated with the application must be permitted for READ access to the profile.
• If the real-time interface resource profile is defined, the user ID that is associated with the application must be permitted for READ access to the profile.
• If the real-time interface resource profile is not defined, the user ID of the application must be defined as a superuser (that is, a user ID with an OMVS UID of zero or a user ID that is permitted for READ access to the BPX.SUPERUSER resource in the FACILITY class).
