Although UNIX has concepts such as processes and threads, which are analogous to z/OS concepts such as address spaces and tasks, many signiﬁcant differences exist. For example, in UNIX, ﬁles are byte-oriented streams of data, but in z/OS, ﬁles (data sets) are record oriented. Within z/OS, you have a complete UNIX environment with z/OS UNIX System Services. This UNIX environment is integrated with the “traditional” z/OS environment. For example, you can access a z/OS UNIX ﬁle from a batch job and you can access a data set from a z/OS UNIX application.
Lines that do not contain those slashes, such as the last two lines in this job, are usually embedded input ﬁles. //TSOJOB JOB CLASS=A,NOTIFY=&SYSUID,MSGCLASS=H This line is the job header. It deﬁnes a job called TSOJOB. The CLASS parameter speciﬁes the job’s priority, the maximum amount of resources the job is allowed to consume, and so on. A is a good default in most installations, at least for the short jobs we’ll use in this book. The NOTIFY parameter speciﬁes that a user should be notiﬁed when the job ends.
The ﬁrst person has to create the RACF user, and the second person has to connect the user to the group. 22. To review their meanings, click F1 to see context-sensitive help. The bottom three options, SPECIAL, OPERATIONS, and AUDITOR, enable you to deﬁne a user as a group administrator. Chapter 6, “Limited-Authority RACF Administrators,” explains this in detail. 2, “Displaying a Group,” to verify that MYUSER was added to OMVS correctly. This concludes the exercises for this chapter. By this point, you should be able to create and modify users and groups.
