HP Integrity NonStop Operating System Architecture

( Duration: 5 Days )

The HP Integrity NonStop Operating System Architecture training course provides an in-depth understanding of the H-series and J-series operating systems architecture. It includes Itanium2-based processors and modular I/O. Post S-series changes include debugging, run-time architecture, memory, process control, and synchronization. TNS and TNS/E process executions are explained along with the internals that support user services. User services such as Guardian and Open System Services (OSS) file systems and process control are also examined.

By attending HP Integrity NonStop Operating System Architecture workshop, Participants will learn to:

  • Understand Itanium-based systems
  • Know when to use a particular debugger Understand ordinary DLLs and programs using DLLs
  • Describe how virtual addressing is supported by the addressing schemes of both TNS and TNS/E processes
  • Understand the fundamental tools and mechanisms used by the NonStop operating system
  • Describe memory management process functions Understand the Guardian and OSS file systems and their supporting structures
  • Know the elements of the NonStop operating system that constitute the message system
  • Support HP software products

  • Working knowledge of C/C++ or pTAL

  • System programmers
  • Field analysts
  • Application designers
