OpenVMS Training : Optimizing Performance on OpenVMS

Optimizing Performance on OpenVMS

OpenVMS Training Overview

This course is designed to teach performance concepts relating to the OpenVMS system, and to use these concepts to develop a tuning methodology to interpret, monitor, and adjust performance mechanisms in OpenVMS

OpenVMS Training Prerequisites

It is assumed that the participant has successfully completed both the Fundamentals of OpenVMS: Getting Started and the OpenVMS System Management courses.

OpenVMS Training Course duration

This course requires two (2) days, 70 % lecture, and 30 % lab time.

OpenVMS Training Course Objectives

Upon completion of this course, a system performance analyst will be able to: understand fundamental performance concepts for memory management, CPU management, and I/O management on an OpenVMS system. The ability to use supplied monitors to interpret performance statistics is also included. <
