This course provides a general overview of system mechanisms such as interrupt priority level, spinlocks, CPU context, and access modes. It is designed to examine the components, structures, and mechanisms of the OpenVMS operating system on Integrity Server and Alpha platforms.

Prerequisites

  • Advanced system management skills (completion of Managing Complex Systems or equivalent experience)
  • A general understanding of operating system concepts
  • An understanding of binary and hex numerical representation

Course Objectives

Upon completion of the course, students should be able to:

  • Identify the internals of the operating system
  • Use SDA
  • Describe OpenVMS processes and data structures
  • Understand the OpenVMS scheduling mechanism
  • Describe lock mechanisms and synchronization

Course Audience

OpenVMS system managers
OpenVMS system programmers
