    • A system and method for a general and extensible infrastructure providing monitoring and recovery of interdependent systems in a distributed/clustered system is disclosed. Subsystems, built without provision for high availability, are incorporated into the infrastructure without modification to core subsystem function. The infrastructure is comprised of one or more computing nodes connected by one or more interconnection networks, and running one or more distributed subsystems. The infrastructure monitors the computing nodes using one or more heartbeat and membership protocols, and monitors the said distributed subsystems by subsystem-specific monitors. Events detected by monitors are sent to event handlers. Event handlers process events by filtering them through activities such as event correlation, removal of duplicates, and rollup. Filtered events are given by Event Managers to Recovery Drivers which determine the recovery program corresponding to the event, and executing the recovery program or set of recovery actions by coordination among the recovery managers. Given failures of said event handlers or recovery managers, the infrastructure performs the additional steps of: coordinating among remaining event handlers and recovery managers to handle completion or termination of ongoing recovery actions, discovering the current state of the system by resetting the said monitors, and handling any new failure events that may have occurred in the interim.

    • The present invention provides a method, apparatus, and computer implemented instructions for processing Web and other Internet or Intranet based services. The system for processing Web requests includes a Web server with a connection to the Internet or Intranet with a predefined network bandwidth, a set of primary Web and application server cluster nodes to process the requests, and a dispatcher to allocate requests to nodes; in addition, one or more offload server nodes are connected to the network. Client Web requests arrive at the dispatcher of the Web server, which determines whether the incoming request can be handled at the primary Web server cluster, whether all or part of the user Web request should be offloaded to one of the offload server nodes, or whether the request should be throttled. If the dispatcher determines that the request should be handled by the primary Web server cluster, it is appropriately routed to one of the nodes in the primary Web server cluster; else if the dispatcher determines that the request should be offloaded, one of the offload server nodes or service providers is selected, and the request is either routed to a primary server node with the appropriate indication to offload all or part of the request, or the request is routed to the selected offload service provider; otherwise, the request is throttled by either routing it to a node which returns information that the service is overloaded, or if the Web servers are too busy to provide even an overload indication, then the request is dropped.
    • 本发明提供了一种用于处理Web和其他因特网或基于内联网的服务的方法,装置和计算机实现的指令。 用于处理Web请求的系统包括具有到具有预定义网络带宽的因特网或内联网的连接的Web服务器,用于处理请求的一组主Web和应用服务器集群节点以及向节点分配请求的调度器; 此外,一个或多个卸载服务器节点连接到网络。 客户端Web请求到达Web服务器的调度程序,该服务器确定是否可以在主Web服务器集群处理传入请求,是否将全部或部分用户Web请求卸载到卸载服务器节点之一,或是否 该请求应该被限制。 如果调度程序确定请求应由主Web服务器集群处理,则将其适当地路由到主Web服务器集群中的一个节点; 否则,如果分派器确定应该卸载该请求,则选择卸载服务器节点或服务提供者之一,并且该请求被路由到具有适当指示的主服务器节点以卸载所有或部分请求,或者 请求被路由到所选择的卸载服务提供商; 否则,通过将请求路由到返回服务超载的信息的节点或者如果Web服务器太忙而不能提供过载指示,则该请求被限制,则该请求被丢弃。

    • An affinity-based router and method for routing and load balancing in an encapsulated cluster of server nodes is disclosed. The system consists of a multi-node server, wherein any of the server nodes can handle a client request, but wherein clients have affinity to one or more of the server nodes that are preferred to handle a client request. Such affinity is due to state at the servers either due to previous routing requests, or data affinity at the server. At the multi-node server, a node may be designated as a TCP router. The address of the TCP router is given out to clients, and client requests are sent thereto. The TCP router selects one of the nodes in the multi-node server to process the client request, and routes the request to this server; in addition, the TCP router maintains affinity tables, containing affinity records, indicating which node a client was routed to. In processing the client request, the server nodes may determine that another node is better suited to handle the client request, and may reset the corresponding TCP router affinity table entry. The server nodes may also create, modify or delete affinity records in the TCP router affinity table. Subsequent requests from this client are routed to server nodes based on any affinity records, possibly combined on other information (such as load).
    • 公开了一种基于亲和力的路由器和方法,用于在封装的服务器节点集群中进行路由和负载平衡。 该系统由多节点服务器组成,其中任何服务器节点可以处理客户端请求,但是其中客户端对于优先处理客户端请求的一个或多个服务器节点具有亲和力。 这种亲和力是由于在服务器处的状态是由于先前的路由请求或在服务器处的数据关联。 在多节点服务器上,可以将节点指定为TCP路由器。 将TCP路由器的地址发送给客户端,并向客户端发送客户端请求。 TCP路由器选择多节点服务器中的一个节点来处理客户端请求,并将请求路由到该服务器; 此外,TCP路由器维护包含亲和性记录的关联表,指示客户端被路由到哪个节点。 在处理客户端请求时,服务器节点可以确定另一个节点更适合处理客户机请求,并且可以重置对应的TCP路由器亲和性表项。 服务器节点还可以在TCP路由器亲和性表中创建,修改或删除关联记录。 来自该客户端的后续请求将基于任何关联记录路由到服务器节点,可能与其他信息(如加载)相结合。

    • A method and system for recovering from a failure of a processing node in a partitioned shared nothing database processing system are provided. The processing system may include a pair of processing nodes having twin-tailed-connected thereto a storage device. A first processing node of the pair of processing nodes has a first database instance running thereon which accesses a first data partition on the storage device prior to the failure. Upon detection of the failure, access to the first data partition on the storage device is provided to a third, spare processing node through the second processing node of the pair of processing nodes. The third processing node runs a replacement database instance for the first database instance which was running on the first processing node prior to the failure thereof. The replacement database instance accesses the first data partition on the storage device through the second processing node, thereby recovering from the failure of the first processing node. Access to the first data partition may include using a virtual shared disk utility having a server portion on the second processing node and a client portion on the third processing node.

    • Techniques are disclosed for network distribution and provisioning of applications, such as transactional applications and parallel applications, across multiple administrative domains that ensure compliance with service level agreements. For example, a method of provisioning one or more resources in a distributed computing network to ensure compliance with a service level agreement associated with a computer application includes the following steps. Network performance is monitored between a local domain and one or more cooperating domains connected to the local domain by network paths. A present or predicted violation of the service level agreement is identified based on at least a portion of results of the monitoring step. One or more cooperating domains are selected that can effect compliance with the service level agreement by instantiating one or more network resources within at least one of the selected cooperating domains in response to a request from the local domain. Reconfiguration of the local domain is effectuated to allow the computer application to make use of the one or more newly instantiated network resources within the selected cooperating domain.
