A method, system, computer system, and computer program product that use application requirements, business priorities, and compatibility and dependency among applications to allocate resources among those applications in a clustering environment. A workload policy engine is aware of the resources available within each cluster, as well as the capacities of those resources. Multiple instances of the workload policy engine can be run in different clusters. The workload policy engine can be used in conjunction with disaster recovery products as well as with provisioning software so that new machines can be provisioned in and out of a cluster dynamically, such as in a blade environment. Furthermore, the workload policy engine can be used in conjunction with dynamic repartitioning capabilities provided by different hardware platforms for large computer systems, as well as with performance monitoring software.

Information technology process workflow for data centers

A method, system, computer system, and computer-readable medium to perform root cause analysis of failure of an application program in a clustering environment. Upon the occurrence of a problem or event of interest, cluster configuration data can be obtained to provide a common context for events occurring at different software layers supporting an application. Diagnostic information produced by the different software layers can be obtained from various log files, which are typically in different formats and on different nodes in the cluster. The diagnostic information can be viewed in the context of the cluster and filtered to identify events related to the failure. The related events can be presented in a time-ordered sequence to assist in analysis of the event of interest. Patterns of events that led to the failure can be identified and documented for use in further problem analysis and for taking preventative and/or corrective measures.

Integration of cluster information with root cause analysis tool

A method, computer program product and system that establishes and maintains a business continuity policy in a server consolidation environment. Business continuity is ensured by enabling high availability of applications. When an application is started, restarted upon failure, or moved due to an overload situation, a system is selected best fulfilling the requirements for running the application. These requirements can include application requirements, such as an amount of available capacity to handle the load that will be placed on the system by the application. These requirements can further include system requirements, such as honoring a system limit of a number of applications that can be run on a particular system. Respective priorities of applications can be used to determine whether a lower-priority application can be moved to free resources for running a higher-priority application.
