Parallel Sysplex Overview & Operations
5 Days

The course will concentrate on the operational aspects of the Parallel Sysplex environment. The student will learn about the hardware/software components that constitute a parallel sysplex and the operator functions needed to manage it. Particular attention will be given to the commands necessary to collect information about the status of the sysplex and associated recovery considerations.

AUDIENCE—Course is designed for Computer Operators to manage a Parallel Sysplex. It will include recovery procedures for subsystems, as well as what procedures to follow when a coupling facility rebuild is required.

SESSION CONTENT

SYSPLEX Overview—2 Days
  • What is a Sysplex?
  • Operator Functions
  • Features and Components
Concepts and architecture

  • Compare the differences between a base Sysplex and parallel Sysplex
  • Describe the purpose of the Coupling Facilities three Structure forms (Lock, Cache and List)
  • Describe the various Coupling Facility options and their implementations.
  • Review the software concepts of resource versus data sharing through a Coupling Facility
  • Discuss configuration choices and potential impact on performance

Planning for a Sysplex

  • Identify the required hardware and software components that make up a Parallel Sysplex and describe their function
  • List the factors that will impact the size of Coupling Facility storage needed in the Parallel Sysplex
  • Examine tools and options for sizing a Coupling Facility
  • Describe the reasons for using a stand-alone Coupling Facility vs an LPAR between systems
  • Understand dynamic CF expansion and dynamic CF dispatching mechanisms

Defining a sysplex

  • Describe the requirements for implementing a Coupling Facility and a Structure within it
  • Describe the functions performed by the Coupling Facility channels (Receive and Send) and how they need to be defined through Hardware Configuration Definition
  • List the required data sets for a Sysplex and the purpose of each
  • Indicate the steps necessary to create Sysplex-required data sets
