  • Patent number: 8230107
    Abstract: Provides control of the workload, flow control, and concurrency control of a computer system through the use of only external performance monitors. Data collected by external performance monitors are used to build a simple, black box model of the computer system, comprising two resources: a virtual bottleneck resource and a delay resource representing all non-bottleneck resources combined. The service times of the two resource types are two parameters of the black box model. The two parameters are evaluated based on historical data collected by the external performance monitors. The workload capacity that avoids saturation of the bottleneck resource is then determined and used as a control variable by a flow controller to limit the workload on the computer system. The workload may include a mix of traffic classes. In such a case, data is collected, parameters are evaluated and control variables are determined for each of the traffic classes.

  • Patent number: 7788671
    Abstract: A method, system and apparatus for on-demand application resource allocation. In accordance with the method of the invention, an anticipated workload can be compared to a measured capacity for an application cluster in one or more server computing nodes in a server farm. If the measured capacity warrants a re-configuration of the application clusters, a new placement can be computed for application server instances in individual ones of the server computing nodes. Subsequently, the new placement can be applied to the server computing nodes in the server farm. In this regard, the applying step can include starting and stopping selected ones of the application server instances in different ones of the server computing nodes to effectuate the new placement.

  • Patent number: 7614077
    Abstract: A system for providing persistent access control of protected content is disclosed. The method on a client system includes sending a first request for authentication of the client to a server system. Subsequently, the client is authenticated by the server. Next, a user on the client attempts to access a file comprising a trailer and content encrypted with an encrypting key. Then, a second request for access to the content is sent to the server by the client, wherein an identifier from the trailer is included in the second request. The identifier identifies the content or an access control policy of the content. The server determines that the second request is in accordance with an access control policy associated with the content, and grants access to the content. Lastly, the client accesses the content in accordance with the access control policy.
