Oracle Essentials provides an invaluable, all-in-one introduction to the full range of Oracle features and technologies. It distills the enormous amount of information about what Oracle is, where it came from, and what the latest releases do.

Oracle Essentialsexplains what's new and important about Oracle's revolutionary releases, Oracle8 (the "object-relational database") and Oracle 8i (the "Internet database"). It covers Oracle products, overall architecture, data structures, and system management and tuning. It describes multiuser concurrency, OLTP, high availability, data warehousing, distributed databases, and extensions for Oracle8 and Oracle8i, including the latest Java and Web technologies. Oracle Essentials also includes an appendix full of references to additional online and offline resources.

Another recently released Oracle title, Oracle8i Internal Services for Waits, Latches, Locks and Memory, is aimed especially at administrators and developers who need detailed internal information to do advanced performance tuning.

Oracle8i Internal Services lays a foundation for advanced performance tuning of the Oracle database. Based on Oracle8i release 8.1, the book describes many of the secrets of Oracle's internal services: data structures, algorithms, and undocumented Oracle system statistics. Main topics are: waits, latches, locks (including instance locks, used in parallel server environments), and Oracle's use of memory.
