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.

Mainframe Training 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.

Mainframe Training Prerequisites

Basic understanding of the OS/390 Operating System, CICS/DB2/VTAM/MVS/JES2 Commands. Working knowledge of the Hardware Master Console.

Mainframe Training Course duration

5 days
