A method includes determining whether an application instance has properly used computing resources to process a workload request, wherein the determination is based on one or more characteristics of the workload request to be processed. The method determines whether the application instance is operating properly, based on the determining of whether the application instance has properly used computing resources based on whether the computing resources have been accessed by the application instance a sufficient number of times; and based on the determination that the application instance is not operating properly, initiates an action to prevent the application instance from improperly processing workload.

Detecting application instances that are operating improperly

A method includes determining whether an application instance has properly used computing resources to process a workload request. The determination is based on one or more characteristics of the workload request to be processed. The method can include determining whether the application instance is operating properly, based on the determining of whether the application instance has properly used computing resources. Based on the determination that the application instance is not operating properly, the method initiates an action to prevent the application instance from improperly processing workload requests.

Embodiments relate to information technology resource management and scaling. According to one aspect, an upcoming event impacting an application operating on one or more resources is identified. A workload on the application is predicted based on the upcoming event identified and historical data about a previous event having similarity with the upcoming event. The prediction is performed using a predefined rule. A number of resources required to process the predicted workload is ascertained using a past scaling history of the application. The resources are scaled based on the ascertained number of said resources determined before the occurrence of the event.

Information technology resource management

Processing requests may be routed between a plurality of runtime environments, based on whether or not program(s) required for completion of the processing requests is/are loaded in a given runtime environment. Cost measures may be used to compare costs of processing a request in a local runtime environment and of processing the request at a non-local runtime environment.

Managing the processing of processing requests in a data processing system comprising a plurality of processing environments

Provided are a computer program, method and system providing simplified administration of groups of computer programs. Command target qualifiers are defined which enable a command to be targeted at either an individual computer program or all members of a group of computer programs. Additionally, scope parameters are defined which enable a command to be targeted at specific computer system resources managed by the computer programs within the group. The computer system resources which are to be accessible to all members of a group have an associated scope parameter defining shared or group access and are held in shared storage, whereas computer system resources to be accessed by only one computer program in the group have a corresponding scope parameter and are held in the local storage of the individual computer program. The invention enables a reduction of the time taken to perform administration and control operations for the group and reduces the risk of inconsistent specification of commands that can arise when a system administrator is required to repeat entry of a command several times.

Administration of groups of computer programs, data processing systems, or system resources

A data processing apparatus for carrying out workload management with respect to a group of servers in an asynchronous client/server computing system, has: a device for receiving a work request from a client application; a device for consulting availability data concerning the group of servers and for selecting a particular server in the group to be used to satisfy the received work request on the basis of the consulted availability data, where the consulted availability data is always used in its present state when the work request is received, irrespective of whether availability data has been received for each server in the group, in order to select a server from the group; and a device for placing the received work request in a transmission queue where it awaits transmission to the particular server in the group.
