Abstract: PROBLEM TO BE SOLVED: To efficiently manage a complicated set of high-availability resources by allowing a cluster system to support the resource group fail-over between two arbitrary nodes in a large-scale clusters of 2 nodes. SOLUTION: A cluster computer system 200 is provided so as to actualize the high availability of an NT-server-based application and Microsoft cluster service(MSCS) supports a fail-over function in a cluster of two nodes 202 and 204 and a common disk 208. If a resource gets out of order, MSCS restarts the faulty resource on a local node or moves the resource group to another node. Two nodes in the MSCS cluster have mutual heart beats 206, and if one node gets out of order, all resource groups are restarted on remaining nodes. After this fail-over event, the system is initialized.

Abstract: A proxy is integrated within an F SSO environment and interacts with an external identity provider (IdP) instance discovery service. The proxy proxies IdP instance requests to the discovery service and receives responses that include the IdP instance assignments. The proxy maintains a cache of the instance assignment(s). As new instance requests are received the cached assignment data is used to provide appropriate responses in lieu of proxying these requests to the discovery service thereby reducing the time needed to identify the required IdP instance. The proxy dynamically maintains and manages its cache by subscribing to updates from the discovery service. The updates identify IdP instance changes (such as servers being taken offline for maintenance new services being added etc.) occurring within the set of geographically distributed instances that comprise the IdP service. The updates are provided via a publication subscription model such that the proxy receives change notifications proactively.

Abstract: A clustered computer system provides both speed and reliability advantages. However, when communications between the clustered computers are compromised those same computers can become confused and corrupt database files. The present method and apparatus are used to improve the management of clustered computer systems. Specifically, the system expands the number of nodes available for failover conditions. Further, provision is made for returning the system to an initial state after a failover event.
