摘要： Described is a technology in a network load balancing system (node cluster), by which client affinity is preserved across cluster configuration changes, including for new connections from a previous client. Each node maintains a list of the clients that are to remain (have affinity, or “stickiness”) with that node, including following bucket redistribution resulting from convergence. Each affinity list is communicated during convergence so that other nodes may build an exception list or lists. Via a node's exception list, the node that owns a bucket corresponding to a client knows of the affinity with another node and thus drops any packets from that client. Affinity may expire, whereby the node having affinity with that client releases it and notifies the node owning the bucket for that client that the client is no longer to be treated as an exception.

摘要： The acquisition of a lock among nodes of a divided cluster is disclosed. A method is performable by each of at least one node of the cluster. A node waits for a delay corresponding to its identifier. The node asserts intent to acquire the lock by writing its identifier to X and Y variables where another node has failed to acquire the lock. The node waits for another node to acquire the lock where the other node has written to X, and proceeds where Y remains equal to its own identifier. The node waits for another node to acquire the lock where the other node has written to a Z variable, and writes its own identifier to Z and proceeds where the other node has failed. The node writes a value to Y indicating that it is acquiring the lock, and maintains acquisition by periodically writing to Z.

摘要： An apparatus utilizes distributed coordinating members to distribute member-specific state data to subscribing members in a distributed computing system. Member-specific state data is associated with different subjects, and coordinating members are configured to manage state data associated with particular subjects such that a reporting member that needs to report member-specific state data associated with a particular subject forwards that state data to a coordinating member associated with that subject. Once received, the coordinating member then distributes the member-specific state data to any members that have subscribed to receive state data associated with that subject.

摘要： Systems and methods improve the equitable distribution the processing capacity of a computing device processing work items retrieved from multiple queues in a workflow system. A retrieval priority is determined for each of the plurality of queues and work items are retrieved from each of the multiple queues according to the retrieval priority. The retrieved work items are then stored in a central data structure. Multiple processing components process the work items stored in the central data structure. The number of processing components is selectively adjusted to maximize efficiency.

摘要： A method, system, and computer program product for implementing policies in a managed systems environment is provided. A plurality of the heterogeneous entities is organized into a system resource group (SRG). Each of the plurality of heterogeneous entities is visible to an application operable on the managed systems environment. The system resource group is subject to at least one membership requirement, defines a relationship between at least two of the heterogeneous entities, contains at least one policy defining an operation as to be performed on the system resource group for a domain of the managed systems environment, and defines at least a portion of a policy framework between the system resource group and an additional system resource group organized from an additional plurality of the heterogeneous entities. The system resource group expands according to an action performed incorporating the relationship, policy, or policy framework.

摘要： A distributed computing system conforms to a multi-level, hierarchical organizational model. One or more control nodes provide for the efficient and automated allocation and management of computing functions and resources within the distributed computing system in accordance with the organization model. The model includes four distinct levels: fabric, domains, tiers and nodes that provide for the logical abstraction and containment of the physical components as well as system and service application software of the enterprise. A user, such as a system administrator, interacts with the control nodes to logically define the hierarchical organization of distributed computing system. The control nodes are responsible for all levels of management in accordance with the model, including fabric management, domain creation, tier creation and node allocation and deployment.

摘要： A network provides distributed client services based on participation in respective resource groups by computing nodes, each resource group including a corresponding resource requirement for any computing node that joins the corresponding resource group for execution of the corresponding distributed client service. Each computing node, in response to determining its corresponding available node capacity, is configured for selectively creating and joining at least one new resource group for execution of a corresponding distributed client service having a corresponding resource requirement, and/or selectively joining at least one of the available resource groups, based on the corresponding available node capacity satisfying the corresponding resource requirement. Each distributed client service also includes service attributes that define parameters for execution of the distributed client service, and data attributes that define the attributes required for data to be used in the distributed client service.

摘要： A distributed computing system conforms to a multi-level, hierarchical organizational model. One or more control nodes provide for the efficient and automated allocation and management of computing functions and resources within the distributed computing system in accordance with the organization model. A user, such as a system administrator, interacts with the control nodes to logically define the hierarchical organization of distributed computing system. The control node includes an automation subsystem having one or more rule engines that provide autonomic control of the application nodes in accordance with a set of one or more rules. A pluggable, application-specific application governor is selected and installed within the control node to provide an application-independent interface through which the rule engines interact to control the deployment, execution and monitoring of the applications within the distributed computing system.
