Implementing TCP/IP on z/OS

Audience

This course is designed for system programmers who will be responsible for implementing TCP/IP on z/OS.

Prerequisites

Delegates are expected to be familiar with:

• TCP/IP, which may be obtained from our Understanding TCP/IP course.
• z/OS, which may be obtained from our z/OS for Beginners course.
• TSO/ISPF, which may be obtained from our TSO/ISPF workshop course.
• UNIX Services on z/OS, which may be obtained from our Introduction to UNIX Services on z/OS course.
• General UNIX user facilities, which may be obtained from our UNIX The Essentials course.

Duration

3 days. Hands on.

Course Objectives

The course will provide delegates with detailed implementation plan for the implementation of TCP/IP. During which they will be involved with exercises which involve configuring a TCP/IP stack on z/OS including a network interface, telnet and ftp.
