Who should attend: Systems administrators, capacity planners, performance analysts and application developers who use Solaris. Solaris users who wish to know more about the system they're using and the information they can get from bundled tools. Anyone interested in operating system internals.

The installed base of Solaris systems being used for various commercial data processing applications across all market segments and scientific computing applications has grown dramatically over the last several years (and continues to grow). As an operating system, Solaris has evolved considerably along the way, with some significant changes made to the UNIX SVR4 source base on which the early system was built. An understanding of how the system works is required in order to design and develop applications that take maximum advantage of the various features of the operating system, understand the data made available via bundled system utilities, and optimally configure and tune a Solaris system for a particular application or load.

This course covers the major components of the Solaris operating system, including:

	Process/thread/dispatcher subsystem, virtual memory, filesystems and I/O interfaces
	Kernel data structures and algorithms discussed for all the major subsystems, with descriptions of the data extraction points used by the bundled tools (e.g. sar, vmstat, mpstat, etc.)
	Several unbundled tools and utilities (e.g. ProcTool, MemTool)
	Implementation of the kernel locking primitives (e.g. mutexes, condition variables)
	System clocks (hardware and software)
	64-bit kernel, linkers and libraries
	System calls, interprocess communication
	Kernel tuneable parameters

After attending this seminar, participants will have a solid understanding of the internals of the major areas of the Solaris kernel that they will be able to apply to systems performance analysis, tuning, load/behaviour analysis and application development.
