HP Integrity NonStop Operating System Architecture

Course overview

This 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. The 5-day course is a combination of lecture and live demonstration using HP servers.
