Live Application Mobility in AIX 6.1: Application Mobility Using WPARs

Download now Free registration required

Executive Summary

The most popular innovation of IBM AIX 6.1 is arguably workload partitioning. Workload partitioning allows one to have fewer operating system images on the managed system, which is accomplished by allowing virtualization of operating system resources. Live Application Mobility is an important component of workload partitioning and provides for increased availability for Workload PARtitions (WPARs). Simply put, it allows one to move WPARs from one Logical PARtition (LPAR) to another while the WPARs are up and running. It provides automatic, policy-based relocation of workload between systems using WPARs. This paper explores how and when to use Live Application Mobility and how to configure a system and its applications to run it.
