HIERARCHICAL MANAGEMENT OF THE DYNAMIC ALLOCATION OF RESOURSES IN A MULTI-NODE SYSTEM

摘要

Approaches are used for efficiently and effectively managing the dynamic allocation of resources of multi-node database systems between services provided by he multi-node database server. A service is a category of work that is hosted on the database server. The approaches manage allocation of resources at different levels. for services that use a particular database, the performance realized by the services is monitored. Resources assigned to the database are allocated between these services to insure performance goals for each are met Resources assigned to a cluster of nodes re allocated between the databases to ensure that performance goals for all the services that use the databases are met Resources assigned to a farm of clusters are assigned amongst clusters based on service level agreements and back-end policies, lie approach uses a hierarchy of directors to manage resources at the different levels.
