UNIX Implementation and Use on z/OS

Prerequisites:

Delegates should be familiar with z/OS, TSO and JCL.

Course Description:

This course is based on z/OS Version 1 Release 7 and provides the participant 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.

At the end of the course the delegate will be able to perform the following activities:

• 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.
