TCP/IP Diagnostic and Problem Determination Techniques for the z/OS Environment

Course:  ZOSNET
Duration:  4 Days
Level:  II
Course Summary

This course provides students with a comprehensive grounding in the philosophy, capabilities, structure, commands and interactions of TCP/IP with other hardware and software components found and implemented within the z/OS environment. Students will leave the class competent and confident to analyze, diagnose and resolve TCP/IP problems encountered within that environment.

The class is divided into four broad segments. Firstly the class reviews the concepts, principles and terminology behind the TCP/ IP protocol. Secondly the class covers the implementation of TCP/IP under z/OS, the required parameters, its close relationship VTAM/SNA and interaction with application subsystems. Thirdly the Operator Commands required for monitoring and controlling the Network environment will be discussed. The fourth and final segment covers the tools and procedures required for problem resolution.

Wherever possible the instructor will make reference to the client' s current and anticipated hardware and software configurations.

OPERATING AND CONTROLLING TCP/IP UNDER z/OS

  • Use z/OS commands to control TCP/IP resources and debug simple network problems
  • START Command
  • STOP Command for each server with outstanding calls to TCP/IP
  • STOP Command for each connected server that does not have outstanding calls
  • DISPLAY Command – relevant options related to the TCP/ IP address space
  • MODIFY Command – relevant options related to the TCP/ IP address space
  • VARY Command – relevant options related to the TCP/ IP address space
  • TSO Command options
  • UNIX Command options
  • Activate and analyze trace data to identify the probable source of network problems

TOOLS AND PROCEDURES FOR PROBLEM RESOLUTION

  • Type of problem, ABEND, hang or loop?
  • VTAM, TCP/IP or other component – identify the root cause?
  • Z/OS I/O problem?
  • Shortage of z/OS Common Storage?
  • Performance problem?
  • Document the problem
  • Problem analysis tools, procedures and techniques
  • Develop reliable diagnostic techniques for solving TCP/IP problems
  • Tools and methods for failure capture and discovery
  • Operator commands for problem determination
  • Common failures and faults: case studies
  • Understanding logical connections between servers and clients
  • Internal communication between TCP/IP tasks
  • Activating and analyzing traces using z/OS system tools
Who Should Take This Course

A general exposure to the z/OS environment is desirable, along with practical experience of configuring, controlling and monitoring the z/OS environment.
