摘要:
A service request routing system and method includes a model table configured to store resource models. A monitor is coupled to the model table and programmed both to model resource consumption in a service providing infrastructure, and also to store the modeled resource consumption in the model table. A router is coupled to the model table, and the router is programmed to route each service request to a corresponding service instance disposed in an associated service host having a service providing infrastructure. The associated service host includes a grid host in a grid computing system.

A method, apparatus, and program product for providing access control in a collaborative environment are provided. A pool of approvable candidates for use in building an access control list for a project team are provided by matching attributes for potential candidates with requirements for the project, with the pool being larger than a projected size for the project team. In response to a vacant role on the project team, an invitation to join the project team is sent to an approvable candidate in the pool. At least one of the access control list or the pool is modified based upon an action by the approvable candidate.

摘要:
A context-sensitive pre-evaluation analysis of a set of rules is performed based on the circumstance or the current state of a rule clause directed to an infrequently changing condition. A group of multiple-clause rules are identified which each have a clause defining an infrequently changing condition for evaluating a state of a resource. The current state of the resource is monitored. If the identified group of multiple-clause rules, which cannot evaluate as TRUE under the context of the current state the resource, the identified group of multiple-clause rules are excluded from consideration by the rules engine. The rules engine will then encounter fewer rules to evaluate for a solution. The identified group of multiple-clause rules is further analyzed in the context of the infrequently changing condition for the current resource state. State metrics that are defined by clauses of the identified multiple-clause rules, those that cannot evaluate as TRUE, are identified. Those metrics are then also excluded from consideration by the rules engine. Thus, the rules engine will encounter fewer rules and/or event states that cannot be evaluated to a solution. The context-sensitive pre-evaluation analysis of the rules is performed out-of-band as the rules engine traverses the rule.
摘要:
A method for routing service requests to service instances in a service providing infrastructure is disclosed. A service request is received. Computing resource vectots for at least two service hosts are computed, and each of the service hosts have a corresponding service providing infrastructure. A resource model for the service request is retrieved. The retrieved resource model are matched to each of the resource vectors to identify a best-fit resource vector. The service request is routed to a selected service host associated with the identified best-fit resource vector. Processing of received service requests is monitored. Individual resource components in the service hosts which are consumed during the processing are identified. Resource models for the service requests are produced based upon the identified individual resource components in the service hosts. A time series model is computed for each of the service requests based upon the identified individual resource components.

摘要:
A composite application may be assembled from one or more component services, and at least one component service of the composite application is monitored. A determination is made of a probability of breach for each monitored component service of the composite application and an economic metric of the composite application is computed based upon each determined probability of breach. The economic metric may also consider and expected warranty cost provided to a requestor of the composite application. At least one parameter associated with the composite application or monitored services is then adjusted to maximize overall composite application performance based upon the economic metric.

A grid coordinator which has been configured for autonomic failover can include a monitor communicatively linked to a multiplicity of grid hosts in a services grid. A metrics store can be coupled to the monitor and configured to store service metrics for individual service instances in the grid hosts. Optimization logic can be programmed to compute a best-fit between metrics stored for a set of service instances in a failed grid host, and platform metrics determined for a proposed replacement grid host. Finally, a failover processor can be coupled to the monitor and the optimization logic and communicatively linked to the grid hosts to create a new set of service instances in the proposed replacement grid host to replace the set of service instances in the failed grid host according to the best-fit in the optimization logic.
摘要:
A method and system are described which allow programs to become dynamically reconfigurable without programmer intervention. This means that the programs can be dynamically distributed among multiple computers within a computer network without modification to the source code of the programs running on the system. In addition, the method and system described allow an administrator of the system to specify conditions under which reconfiguration is to occur without modification to the source text of the program to be dynamically reconfigured.

Systems, methods and computer program products allow intranet administrators to assign, generate and deliver content to users of an intranet. Intranet users are defined and assigned to various defined user groups. Units of content available to users of an intranet are also defined and assigned to various defined content groups. The defined content groups are then associated with the defined user groups such that each of the defined user groups has at least one of the defined units of content associated therewith. A content page creation profile is provided for each defined user and is configured to control how content is displayed within a user's customized content page. Through identified relationships of user groups and content groups, the units of content assigned to a user can be determined and a content page containing the assigned units of content can be created and delivered to a user.
