Abstract: A computer program communicates with a partition manager in the logical partition where the computer program is run. When resource allocation in the logical partition dynamically changes, the partition manager notifies the computer program of the configuration change. The computer program may autonomically adjust one or more configuration settings that affect performance of the computer program to dynamically tune the computer program to optimal performance each time the allocation of resources within the logical partition changes. The partition manager may notify the computer program of an impending change in resource allocation in the logical partition that runs the computer program, which allows the computer program to reconfigure its configuration setting(s) before the partition manager changes the resource allocation in the logical partition.

Abstract: A method for optimizing a software application within a computer system is disclosed. A controller and a group of agents are initially provided within a computer system. Each agent within the group is assigned a different range of numbers, and each range initially has an identical size. After a random number has been generated by the controller, an agent among the group of agents having an assigned range within which the random number falls is requested to change a parameter of a software application within the computer system. The range of numbers assigned to that agent is then adjusted according to a performance result of the computer system after the parameter change.
