OpenVMS Training : Advanced OpenVMS Systems Management

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. Practical uses of OpenVMS Internals, such as for crash dump analysis, process / resource issues, and general understanding of OpenVMS mechanisms, will also be shown.

OpenVMS Training Prerequisites

Participants are assumed to have background knowledge of VMS Systems Management (mainly for parameter information), and a working knowledge of DCL programming.

OpenVMS Training Course duration

This course requires five (5) days, 60 % lecture, and 40 % 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 in an OpenVMS system. The ability to use supplied monitors to interpret performance statistics is also included. Participants will also be able to do brief analysis of a systems crash, determine the reason for a process' MWAIT condition, and learn to use the System Dump Analyzer (SDA) utility.
