Course overview

OpenVMS version 8.4 introduces many new and modified features to the operating system. This 2-day course presents the new and changed features of OpenVMS in four parts:

  • User changes
  • System management changes
  • Programming changes
  • Associated product changes


Students should have skills and knowledge with OpenVMS through v8.3. OpenVMS Fundamentals (U3716) or equivalent is required and depending on your role, other courses are highly recommended. OpenVMS System Management I (U3724) for system managers and OpenVMS v8.3 Programming Features (HE364) for programmers and engineers.


  • This course is intended for those who need to understand the OpenVMS V8.4 differences at the user, system manager, and programmer levels
