Job grading enables administrators to divide jobs into work loads that compete against others of similar size, type, priority, or all three. You can sort work loads using any one or a combination of these factors. You can also set access permissions allowing users and groups to obtain each grade of UUCP service.
In the SunOS release 4 software, the user has to choose the grade when the job is submitted. Grades are a single letter, not a name, as they are in the Solaris 7 operating environment. Solaris 7 systems enable administrators to define job grades for an entire site.
