UNIX Implementation and Use on z/OS

This course provides attendees with an overview of UNIX Services in a z/OS system. It concentrates on the non-UNIX facilities available in z/OS to perform UNIX type work.

This course is for anyone within an existing z/OS installation who requires an appreciation of UNIX and how it fits into an existing z/OS operating system.

z/OS system programmers and system administration staff who are responsible for implementing and/or maintaining UNIX on a z/OS system should also attend this course. It is also for UNIX professionals who are implementing UNIX and UNIX applications on a z/OS system and need to understand the environment.

Delegates should be familiar with z/OS, TSO and JCL. This knowledge can be obtained by attending our z/OS Foundation Fast Track (ZOS, TSO, JCL) course.

By the end of the course, delegates will be able to:

• Use TSO ISHELL to create and view UNIX files and directories, perform data transfer between z/OS data sets and UNIX files.
• Use TSO commands to create and view UNIX files and directories, perform data transfer between z/OS data sets and UNIX files.
• Use UNIX commands to create and view UNIX files and directories, perform data transfer between z/OS data sets and UNIX files.
• Use JCL to perform batch functions running UNIX shell scripts.
• Set up UNIX Services on z/OS.
• Monitor and control UNIX on z/OS.
• Set up and maintain HFS and zFS file systems in both a single system and in a shared HFS within a SYSPLEX.
• Set up and administer UNIX users.
