This article explores how and when to use Live Application Mobility and how to configure a system and its applications to run it.

Storage Protection Keys on AIX Version 5.3
This paper will describe a new hardware feature called storage protection keys, or storage keys for short, that will assist the application programmer in locating these inadvertent memory overlays. The storage protection keys application programming interface (API) for user space applications is available in AIX® Technology Level 5300-06 and is supported on all IBM System p™ POWER6™ processor-based servers running this technology level.

DB2 Enterprise Server performance with POWER5+ and AIX 5L multipage support
This paper talks about the IBM DB2, Version 9 for Linux, UNIX, and Windows exploitation of multiple page sizes and also shares some performance results, as measured internally on IBM POWER5+ processor-based systems running the IBM AIX 5L operating system.

Guide to Multiple Page Size Support on AIX 5L Version 5.3
AIX 5L Version 5.3 with the 5300-04 Recommended Maintenance Package provides rich support for an application to utilize the different page sizes provided by the POWER5+ processor. Larger page sizes can be used for an application's memory without any application changes, allowing applications to easily utilize the performance efficiencies of larger page sizes like 64KB.

AIX 5L NFS Client Performance Improvements for Databases on NAS
Running a database over a file system structure is now a popular alternative to the traditional storage method using raw logical volumes. The performance issues of buffered I/O and concurrency have been solved with evolving file system technology and are now available on NFS with the latest level of AIX 5L V5.3 ML 3.

Using the Geographic LVM in AIX 5L
This book provides complete planning, installation, configuration and usage information for GLVM in an HACMP/XD environment. This white paper provides some additional information you may find useful to manage a standalone GLVM configuration without HACMP.

Experiences installing Oracle Application Server 10g (9.0.4) Cold Failover Cluster on AIX 5L
The objective of this document is to provide assistance to those involved with the installation of Oracle Application Server 10g (9.0.4) (AS10g) "Cold Failover Cluster" (CFC) solution on IBM AIX 5L (5200) operating system. This paper addresses the preparation of the hardware infrastructure for a CFC deployment of AS10g, the installation of the Oracle AS10g software stack, and some validation tests for installation.

Service Update Management Assistant (SUMA) on AIX 5L
The Service Update Management Assistant (SUMA) moves the system administrator away from the manual task of retrieving maintenance updates from the Web. SUMA, which is included in the base AIX 5L Version 5.3 operating system, provides clients with flexible, policy-based options allowing them to perform unattended downloads of all AIX 5L updates from the IBM eServer Support Web site.

IBM eServer p5 - AIX 5L Support for Micro-Partitioning and simultaneous multi-threading
IBM eServer p5 servers with POWER5 processors contain new technologies called simultaneous multi-threading and optionally, Micro-Partitioning. AIX 5L Version 5.3 contains support for these new technologies. This white paper describes these new technologies and the AIX 5L support for them.

Improving Database Performance With AIX Concurrent I/O
A new file system called "Concurrent I/O" (CIO) was introduced in the Enhanced environments, particularly commercial relational databases. In many cases, the database performance achieved using CIO with JFS2 is comparable to that obtained by using raw logical volumes. This paper details the implementation and operational characteristics of CIO, and presents the results of our performance evaluation of CIO with Oracle9i Database.
