"The SolarisTInternals volumes are simply the best and most comprehensive treatment of the Solaris (and OpenSolaris) Operating Environment. Any person using Solaris - in any capacity - would be remiss not to include these two new volumes in their personal library. With advanced observability tools in Solaris (likeDTrace), you will more often find yourself in what was previously unchartable territory. SolarisT Internals,Second Edition, provides us a fantastic means to be able to quickly understand these systems and further explore the Solaris architecture - especially when coupled with OpenSolaris source availability. - Jarod Jenson, chief systems architect, Aeysis"The SolarisT Internals volumes by Jim Mauro and Richard McDougall must be on your bookshelf if you are interested in in-depth knowledge of Solaris operating system internals and architecture. As a senior Unix engineer for many years, I found the first edition of SolarisT Internals the only fully comprehensive source for kernel developers, systems programmers, and systems administrators. The new second edition, with the companion performance and debugging book, is an indispensable reference set, containing many useful and practical explanations of Solaris and its underlying subsystems, including tools and methods for observing and analyzing any system running Solaris 10 or OpenSolaris. - Marc Strahl, senior UNIX engineerSolarisT Internals, Second Edition,describes the algorithms and data structures of all the major subsystems in the Solaris 10 and OpenSolaris kernels. The text has been extensively revised since the first edition, with more than 600 pages of new material. Integrated Solaris tools and utilities, including DTrace, MDB, kstat, and the process tools, are used throughout to illustrate how the reader can observe the Solaris kernel in action. The companion volume, SolarisT Performance and Tools, extends the examples contained here, and expands the scope to performance and behavior analysis. Coverage includes:Virtual and physical memoryProcesses, threads, and schedulingFile system framework and UFS implementationNetworking: TCP/IP implementationResource management facilities and zonesThe SolarisT Internals volumes make a superb reference for anyone using Solaris 10 and OpenSolaris.
