Course Description

This TCP/IP for Z/OS: Diagnostics and Debugging course is designed to give you the skill required to diagnose and debug TCP/IP problems when operating on z/OS. This skill consists in developing knowledge of commands and tools together with a methodology in tackling TCP/IP problems.

The lab activity and paper projects provide an opportunity to debug real problems.

Objectives

  • Learn what commands are useful in a z/OS environment to control TCP/IP resources, the TELNET application, and debug TCP/IP simple network problems
  • Learn which trace types (packet, TELNET, FTP, and so forth) are available in a z/OS environment and know:
    • What kind of information can be found in a trace
    • When to activate a trace
    • How to activate a trace
    • How to interpret a trace (for the packet trace there is a dedicated topic)
  • Use the proper diagnostic technique to approach TCP/IP problems
  • Describe the Syslog function in the UNIX environment and know how to configure the /etc/syslog.conf file
  • Understand how to handle and modify the translate tables used by many TCP/IP applications that connect to remote systems which use ASCII character coding
  • Activate and interpret several trace types, and debug some real problems which involve the use of various application protocols.

Audience

  • This intermediate course is for anyone who works on TCP/IP networks and provides support in the resolution of communication problems on z/OS.

Prerequisites

  • You should have:

  • Completed TCP/IP for z/OS Implementation Workshop (CB695)
  • Knowledge of z/OS.
