Scaling Oracle8i(tm): Building Highly Scalable Oltp System Architectures [with Cdrom]

As open systems continue to replace traditional mainframe systems, system scalability is becoming an increasingly important topic. Although far more flexible than mainframe systems, open systems applications tend to be less reliable and more difficult to scale. There is no cookbook approach to solving this challenge: A thorough understanding of the technologies involved is essential for designing scalable solutions that meet long-term business needs.

"Scaling Oracle8i" offers valuable insights and techniques for designing reliable and scalable online transaction processing (OLTP) applications using Oracle. This book focuses on providing the in-depth information about Oracle and the underlying hardware required to build systems that scale effectively.

You will find coverage of relevant hardware and I/O operation; benchmark and database monitoring systems; Oracle internals, operation, and implementation; and UNIX operating system issues that impact Oracle performance and scalability. Essential topics covered include:

• Critical scalability concepts, including latches and locks, lists, hashing, and caching
• A briefing on various hardware architectures, including symmetric multiprocessor, clustered SMP, ccNUMA, and massive parallel processors
• I/O technology, including the physical attributes of I/O systems and RAID technology
• Producing application benchmarks using Oracle trace files
• An introduction to the Tcl-based Oracle scripting tool dbaman, for easy, general purpose database programming
• Interrogating the Oracle fixed tables to derive operational data
• Oracle Parallel Server
• The inner workings of the UNIX kernel and virtual memory system
• Oracle's Virtual Operating System abstraction interface, including hardware vendor co-engineering
• Writing scalable SQL
• Using TP monitors
• Performance tuning
• Scaling large Oracle applications

In addition, a real-life case study of a large-scale Oracle system illustrates concepts, approaches, and experienced-based pointers for implementation. "Scaling Oracle8i" concludes with a look at Oracle's future, including its role in the emerging field of Internet OLTP development.

This is the complete, expert guide to building enterprise-class UNIX-based Oracle OLTP systems that deliver maximum performance and scalability. In Scaling Oracle 8i, one of the world's leading Oracle consultants introduces today's best methods and technologies for building industrial-strength Oracle database systems on UNIX platforms. Understand exactly what scalability means in the enterprise; then discover how to deliver it, step-by-step, from the ground up, through design, testing, construction, maintenance, benchmarking, and ongoing management. Morle covers every component that impacts performance, including hashing, caching, hardware architecture and I/0 subsystems, Oracle database objects, data storage, memory structures, and a detailed review of the Oracle Parallel Server. Readers will find comprehensive coverage of tuning the underlying UNIX platform to improve OLTP response times; including co-engineering the kernel; working with virtual memory, I/0, interprocess communication; and more. Scaling Oracle 8i contains a full chapter on the special issues associated with e-commerce, as well as a detailed case study drawn from one of the world's largest car rental reservations systems. For all enterprise system architects, database engineers, and application developers working with Oracle.
