IBM System z Parallel Sysplex Operations Schulung

Working in a Parallel Sysplex environment
IBM System z Parallel Sysplex Operations

This course is designed so that students can learn how z/OS systems operate in a Parallel Sysplex environment through discussion topics and hands-on lab exercises. You learn problem determination skills, practice enhanced sysplex operations, including management of the coupling facility (CF), and use recovery capabilities provided by the System z servers.

The course consists of six units and 12 hands-on lab exercises.

The course consists of six units and 12 hands-on lab exercises.

The six units describe, define, and explain what a sysplex configuration consists of, the purpose and use of the coupling facility, operational procedures and commands to manage components of the sysplex, the use and purpose of the Sysplex Failure Manager, the importance of time synchronization and how it is achieved, and the IPL process. The six units are as follows:

  • Unit 1: Sysplex overview

This unit describes sysplex terminology, concepts, and benefits provided by a sysplex configuration. It identifies the various software and hardware components that make up the Parallel Sysplex environment.

  • Unit 2: Coupling Facility

The purpose of this unit is to describe the CF link connectivity options, how the CF operates, and the users of the CF. The CF policy is described and explained along with commands to control and monitor the CF.

  • Unit 3: Sysplex operation and recovery

The purpose of this unit is to identify the commands and procedures required to manage a sysplex. Normal, day-to-day and failure-recovery operational procedures for structures, CFs, CF links, and couple data sets are discussed. CF configurations are discussed and sysplex configurations for the highest availability are explained.

  • Unit 4: Sysplex Failure Manager and console operations

This unit describes SFM operation, use, and support that was added with z/OS 1.8 and z/OS 1.9. It also describes sysplex console operations support and use, including console updates that apply to z/OS 1.8 and z/OS 1.10.

  • Unit 5: Sysplex timer and Server Time Protocol operation

This unit describes the importance of time synchronization in a Parallel Sysplex and how it is achieved. It describes the timing configurations (Sysplex Timer and Server Time Protocol) that can be used in the System z servers, including terminology and configuration support.

  • Unit 6: z/OS IPL flow

This unit describes the major phases within a z/OS initial program load (IPL) operation, the steps required to perform a successful IPL, and how to resolve problems that might be encountered during an IPL of a z/OS system.

The lab exercises consist of nine labs that are included to address sysplex configuration setup, parmlib configuration, and management of couple data sets, structures, connections, and coupling facilities.

Three optional labs are also included to address how JES2 checkpoint can be moved from DASD to CF and back again, Sysplex Failure Manager (SFM) settings and policies, and managing systems within a sysplex.

  • Exercise 1: Set up to access the lab environment

This exercise provides the procedures necessary to log on to the lab environment.

  • Exercise 2: Sysplex parmlib configuration

This exercise provides an opportunity to identify the initial parmlib members and some key entries that are defined for a sysplex configuration. These entries are used at IPL time.

  • Exercise 3: Using z/OS commands to determine sysplex status

This exercise provides an opportunity to use MVS commands to determine the operational status of all sysplex components.

  • Exercise 4: Managing XCF signaling paths

This exercise provides an opportunity manage pathin and pathout signaling.

  • Exercise 5: Couple data sets

This exercise provides an opportunity to determine the operational status of all the couple data sets in use by the sysplex. It also demonstrates the use of z/OS commands to modify CDS settings, remove CDS settings, and return a CDS to the sysplex.

  • Exercise 6: Managing structures within and across multiple CFs

This exercise provides the opportunity to manage sysplex structures by changing the allocation status, manually altering their size, and relocating structures across coupling facilities (CFs).

  • Exercise 7: Managing structures with failed persistent connections.

This exercise provides the opportunity to practice recovery procedures for structures containing failed persistent connections.

  • Exercise 8: Managing coupling facilities

This exercise provides the opportunity to manage coupling facility (CF) links, structures, and CFs. It identifies and demonstrates the use of all forms of the SETXCF REBUILD command and the REALLOCATE command to move structures.

  • Exercise 9: CF Maintenance mode (z/OS 1.9 and above)

This exercise provides you the opportunity to remove a CF from the sysplex using the new MAINTMODE command introduced at z/OS 1.9.

  • Exercise 10: Moving JES2 checkpoint into and out of the CF (optional)

This exercise provides practice moving the JES2 checkpoint data set into and out of a structure in a CF. It also identifies how to delete an allocated structure with zero connections.

  • Exercise 11: SFM lab (optional)

This exercise uses XCF commands to start, stop, and identify SFM policy settings. Additionally, it provides practice in removing a system from the sysplex and returning a system to the sysplex.

  • Exercise 12: Managing systems in a sysplex (optional)

This exercise provides the opportunity to practice removing a system from the sysplex and returning a system to the sysplex.
