Parallel Sysplex Advanced Operations & Recovery
Mainframe Training Overview
The course will concentrate on the operational recovery aspects of the Parallel Sysplex environment. The student will learn about basic problem diagnosis, the commands necessary to display and monitor parallel sysplex status, and the means necessary to recovery from failure scenarios.
Course is designed for Systems Programmers and Computer Operators that must plan for and manage Parallel Sysplex recovery scenarios. This course will include recovery procedures for subsystems, as well as basic diagnostic procedures.
The student should have completed Parallel Sysplex Overview & Operations or have equivalent knowledge.
