Abstract: A method for the automatic selection of computer system parameter values to improve system performance as workload on the system changes. Methods are disclosed for automatically making minor adjustments to computer system parameters and comparing long-term associated performance changes in order to set parameter values so as to obtain improved system performance. The time frame over which a change in a system parameter and the associated system performance change is averaged is adjustable, thus permitting evaluation over shorter or longer periods of times as deemed appropriate. An objective measure of system performance is defined prior to implementation of the present methods. For transaction based systems, average system response-time for a given demand on the system could be, for example, such a measure. For systems executing batch-type workloads, system throughput may be used as the indicator of how well the system is performing.

Abstract: A system and method for generating and sharing consistent application definitions amongst multiple performance and resource management tools. A common interface accepts requests from performance or resource management tools and returns requested process-to-application mapping data. A parameters file contains a common syntax for application definitions, and a module uses the parameters file to determine mapping from processes into applications. A performance monitoring tool for senses current system processes' states and provides measurement data to the mapping module.
