AIX 5L and WebSphere XD

This chapter describes how WebSphere Extended Deployment (XD) can be optimized in an AIX 5L environment. It provides a brief discussion of dynamic logical partitioning and the system resource utilization efficiency that these two products can achieve It provides a brief discussion of dynamic logical partitioning and the system resource utilization efficiency that these two products can achieve on IBM POWER systems.

The five autonomic managers that are functional parts of WebSphere Extended Deployment are also discussed. Finally, processor and memory dynamic reconfiguration events (DR events) are covered, including how DR events can used to integrate with dynamic logical partitioning (DLPAR).

The chapter also examines the dynamic behavior of WebSphere XD and explains how, when there are changes to AIX 5L memory or CPU resources, WebSphere XD can respond by aligning its own resource usage in tandem with a resource change in a partition that is running the AIX 5L operating system.
