TCP/IP Implementation on z/OS

Course: TCPZOS

Duration: 3 Days

Level: II

Course Summary

The course starts with a review of the central concepts, principles and terminology underlying the z/OS TCP/ IP protocol stack and its interactions with other components. It then provides detailed information on implementing the TCP/IP stack in z/OS Communications Server, co-requisite software, and the main TCP/IP applications supplied with it.

What You Can Expect

At the end of this course, delegates will be able to:

Explain the positioning and functionality of the z/OS TCP/IP stack
Implement, modify and tune TCP/IP on the mainframe
Customize the major applications such as FTP that are supplied with the TCP/IP product
Design and administer advanced z/OS TCP/IP features such as dynamic VIPA and Sysplex Distributor

Who Should Take This Course

This course if for z/OS Communications Systems Programmers and Analysts who will plan, implement and tune the TCP side of z/OS Communication Server

Recommended Prerequisites

Delegates are expected to be familiar with:

Basic Mainframe Theory. <

Training Style

The class is led by an instructor in person or by webcast from a coursebook that delegates receive in advance. The coursebook incorporates paper exercises and examples. Significantly better value is achievable, however, if delegates can be coached through custom tasks hands-on in their own estates, using the real-life tooling.
