9.1 WebSphere XD and DLPAR integration
The AIX 5L operating system has new features to improve server manageability. A key feature is the ability to divide a system into logical partitions (LPARs), which can be resized on demand. You can easily add or remove physical memory (RAM), processors (CPU), and I/O devices from the partitions. A logical extension of this feature is the ability to move these resources among the partitions without having to reboot a partition or a system. This feature is called dynamic logical partitioning (DLPAR).
To leverage these new features, WebSphere XD dynamically modifies its own resource consumption for scalability and improved resource utilization. WebSphere XD can monitor and optimize their application server environments or make recommendations based on the observed data. This capability is referred to as dynamic operations.
