An approach is provided in which a resolution manager stores a machine-readable problem, which includes a problem signature, and a human-readable solution in a document. The resolution manager receives an output file from a computer system and matches an output entry included in the output file to the problem signature. In turn, the resolution manager identifies the human-readable solution corresponding to the matched problem signature and provides the identified human-readable solution to the computer system.

Combining problem and solution artifacts

Techniques are disclosed for combining multiple benchmarks for use in assessing characteristics of a computing system. For example, a method for configuring and running multiple benchmarks includes the following steps. A multiple benchmark specification is obtained. The multiple benchmark specification includes multiple individual benchmark specifications and a multiple benchmark workflow describing an ordering according to which the multiple individual benchmarks are to be configured and run. The multiple benchmarks are configured and run according to the ordering identified in the multiple benchmark workflow. Results of the multiple benchmark runs are recorded. One or more specifications or results associated with at least one of the multiple benchmarks are utilized as part of a benchmark specification for at least another of the multiple benchmarks so as to provide consistency between at least the one and the other of the multiple benchmarks.

Method and system for combining multiple benchmarks

Systems and methods of managing problem determination (PD) data provide for obtaining PD data from a plurality of data sources via an input/output (I/O) interface of a data management device and storing the PD data to a memory of the data management device. In addition, an automated diagnostic analysis of the PD data may be conducted on the data management device. An automated discovery manager may provide the ability to find new sources of PD data and to either reconfigure remote systems to send data to the data management device or to automatically retrieve data from remote systems on a configurable schedule. Dynamically updateable database of symptom information can also be used, wherein the data management device may include a dynamically updateable set of analysis modules with which to conduct analysis on the PD data.

A method in a data processing system for detecting and reducing database contention and deadlock caused from within an application server. A determination is made as to whether a set of parameters in a statistical model indicates contention. If the set of parameters in the statistical model indicates contention, an application server administrator is notified of the contention and the number of threads in an application server pool is reduced. If the set of parameters in the statistical model indicates contention is reduced, the number of threads in the application server pool is increased.

Database contention and deadlock detection and reduction within application servers

Methods, systems and computer program products are provided which dynamically balance the load between gateways which provide access between a first computer network and a second computer network. This load balancing includes receiving at a gateway a communication to be transmitted to a second computer network from a source device on the first computer network. The gateway determines, preferably based on an address contained in the communication, through which of the gateways the communication is to be transmitted and then either transmits the communication to the second network or over the first network to the determined gateway. A redirect message may then be sent to the source device to direct subsequent messages to the proper gateway. The gateway determination may be made by dividing a resource identifier into subgroups, summing the subgroups and then dividing the sum by the number of parallel gateways. The remainder may then be used as a gateway identifier.
