OpenVMS Internals for System Managers TR-1SL302-VMS
Price: $4,000.00 / 5 days
Format: Lecture Lab
Course Description:
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. It is intended for students without significant programming backgrounds, who want a better understanding of how OpenVMS works. The 5-day course is 50% percent lecture and 50% percent hands-on labs. HP Course ID: u3729s.
- OpenVMS system managers and application programmers
- Advanced system management skills
- A general understanding of operating system concepts
- An understanding of binary and hex numerical representation
Course Objectives:

The class uses the System Dump Analyzer on a livesystem to examine the data structures that form theoperating system. The dynamics of the operating systemwill be explored through changes to data structuresvisible through SDA.

The focus is on the three major subsystems of OpenVMS:

- Process and scheduling
- Memory Management
- I/O
