Database Performance Tuning on AIX. This IBM Redbook is designed to help system designers, system administrators, and database administrators design, size, implement, maintain, monitor, and tune a Relational Database Management System (RDBMS) for optimal performance on AIX. RDBMS is usually a significant factor in building the profit line of a. Chapter 16 discusses performance monitoring and tuning on AIX AIX Market Share. AIX celebrated its 20th anniversary in January , and it appears to have an extremely bright future in the Unix space. IBM's AIX has been the only Unix that increased its market share through the years, and IBM continues to own the market space for Unix : MC Press, LLC. ISBN: X: OCLC Number: Language Note: English. Notes: "This edition applies to Version of AIX running DB2 Universal Database Version , Oracle Database Server Version , and Informix Dynamic Server Version ". "Maximize your efforts toward effective performance tuning on AIX on IBM's Power Systems (IBM i, AS/, iSeries, System i, AIX, and Linux). With detailed information on optimizing your CPU, memory, disk, and network I/O subsystems, along with data on both AIX and AIX , the author gives detailed instructions on how to tune your system effectively, delivering the performance boost you.
It is focused on AIX versions , , and Oracle 9i, 10g, 11g. It begins with a short description of the most important Oracle DB architectural elements. It continues with an overview of the AIX-related tuning elements that are most crucial for optimal DB activity. This document can be expanded into many different OS or DB-related directions. IBM AIX I/O Performance Tuning I have a IBM Power9 server coupled with a NVMe StorWize V GEN3 storage, doing some benchmarks and noticing that single thread I/O (80% Read / 20% Write, common OLTP I/O profile) seems slow../xdisk -R0 -r80 -b 8k -M 1 -f /usr1/testing -t60 -OD -V BS Proc AIO read% IO Flag IO/s. AIX client: chdev –l hdiskX –a queue_depth=# NOTE:hdisk must not be in used. Otherwise, use the chdev –P and then reboot to take effect the changes. When using VSCSI with physical volume used as backing device, the queue_depth should match on VIOS and AIX client. Performance improvements by tuning . In Accelerating AIX, Rudy Chukran shares AIX know-how, experience, and insight gained from spending more than ten years as one of IBM's tuning experts. This comprehensive book provides key information for both system administrators and application programmers, with: full coverage of monitoring, diagnostic, and development tools; remedies for performance slowdowns; techniques for relieving LAN bottlenecks; and proven methodologies for isolating, analyzing, and solving performance Reviews: 2.
Tuning AIX in an Oracle environment has changed significantly through the years, especially with the advent of Power Systems and virtualization. You simply can’t tune AIX or Oracle the same way today that you would tune 10 years ago. Let’s look at best practices for tuning AIX for Oracle and also provide tips for tuning Oracle as well.
