About this course
Attendance on the RSM course 'TCP/IP Fundamentals' or equivalent experience. . A familiarity with UNIX ais also required and some z/OS systems programming experience would be an advantage, but is not essential.

Objectives
On successful completion of this course, attendees will be able to:
- describe the structure, operation and the addressing mechanisms used in a TCP/IP network
- list the major configuration steps involved in customising TCP/IP for z/OS and explain the Security Server customisation required in z/OS
- explain the purpose and use of Virtual IP addressing (VIPA) and explain how to code for both a static and dynamic VIPA configuration

- describe the purpose and customisation of the DATA data set
- define the host name, domain name and DNS information
- describe the purpose and use of the HOSTS file and the SERVICES data set
- explain the configuration of the TN3270 server and the SNA gateway and explain the VTAM configuration required to support the gateway
