AUTONOMICALLY ADJUSTING ONE OR MORE COMPUTER PROGRAM CONFIGURATION SETTINGS WHEN RESOURCES IN A LOGICAL PARTITION CHANGE

摘要

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 automatically 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.
