Course description

This hands on lab course provides an indepth understanding of the architectural concepts of the NonStop Kernel operating system. You will see the TNS/R platform architecture, the program execution of TNS and TNS/R processes, and the internal functioning of the operating system components that support user services. You will examine user services such as the Guardian/Open System Services file systems, process control, ServerNet technology, DLLs, memory management system and kernel data structures.

Ideal candidate for this course

• Primary audience: System programmers, Field analysts, Application designers, Field support personnel
• Secondary audience: System managers

  • Operating System Tools and Mechanisms
    • Operating system tools, such as linked list,tables, and pools
    • Resource contention controls, such as semaphores and mutual exclusion
    • Process event management mechanisms WAIT and AWAKE
  • Memory Access and Management

    • Physical address caching, context boundaddresses, the physical frame selectionalgorithm, and memory manager functions
  • Message System
    • Fundamental NonStop Kernel message system components of the linker-listener model
    • Steps of interprocess message transfers between processes in the same processor
    • Steps of interprocess message transfers between processes in different processors
    • Message system structures involved in intraprocessor and interprocessor messages
    • Interprocess communication across nodes including Expand and ServerNet Clusters
  • Guardian Process Life Cycle and Management
    • Creation and deletion cycle of a process for a

  • Open System Services (OSS) Process Life Cycle
    • Creation and deletion cycle of a process for an OSS process Guardian File Systems
  • Guardian File Systems
    • Guardian file system
    • Interactions involved with opens, closes, and other selected subjects such as nowaited I/O and synchronization depth (synchdepth)
  • OSS File System
    • OSS file system differences from the Guardian file system
    • How a file is open(), what device types are supported, and file naming
  • Onsite delivery Equipment Requirements
    • One NonStop S-series server with Gxx version of the NonStop Kernel operating system to run labs (NonStop S7000 or above)
    • Four processors (two minimum)
    • One PC compatible workstation per student and one for the instructor with:
      - Intel Pentium processor (minimum)
      - 16 to 64 MB of memory (including 640 KB of conventional memory)
      - VGA monitor
      - 11.5 MB maximum disk space
      - Windows operating system operating system
      - PowerPoint
    • One 6530 or PC terminal per student (similar to above configuration)
    • A NonStop S-series server is strongly recommended to run the lab exercises. An absolute minimal system would be a NonStop K2000 server with the D40 version or higher NonStop Kernel operating system; however, this configuration will require more time to run the labs


After completing this course, you should be able to do the following:
  • Comprehensively understand the NonStop system architectures
