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.
