摘要： Selecting a master node in a multi-node computer system is described. Each node of the multi-node computer system selects a timeout value (e.g., randomly). Each node starts a timer, which is set to expire at the selected timeout value of its corresponding node. The node with the timer that expires earliest broadcasts an election message to the other nodes of the multi-node computer system, which informs the other nodes that the broadcasting node is a candidate for mastership over the multi-node computer system. The other nodes respond to the election message upon receiving it. In the absence of a refusal message from one or more of the other nodes, the candidate is established as master node in the multi-node computer system and wherein the other nodes function as slave nodes therein.

摘要： A clusterware manager on a cluster of nodes interprets a resource profile. The resource profile defines resource profile attributes. The attributes include at least one attribute that defines a cluster dependency based on resource type. The attribute does not identify any particular resource of that resource type. Dependencies between resources are managed based on the attribute that specifies the cluster dependency.

摘要： Allowing for resource attributes that may change dynamically while the resource is in use, provides for dynamic changes to the manner in which such resources are managed. Management of dynamic resource attributes by clusterware involves new entry points to clusterware agent modules, through which resource-specific user-specified instructions for discovering new values for resource attributes, and for performing a user-specified action in response to the new attribute values, are invoked. A clusterware policy manager may know ahead of time that a particular resource has dynamic attributes or may be notified when a resource's dynamic attribute has changed and, periodically or in response to the notification, request that the agent invoke the particular resource-specific instructions for discovering new values for attributes for the particular resource and/or for performing a user-specified action in response to the new attribute values. During the majority of this process, the resource remains available.

摘要： A method for a self-testing clusterware agent is provided. A clusterware agent that includes clusterware-side components and application-side components is configured to interface between a cluster manager and an application. The application-side components are invoked by clusterware-side components via an application programming interface, or API that includes API functions that are invocable by a cluster manager. Without any cluster manager invoking the clusterware agent, one or more of the API functions are invoked.

摘要： A method and mechanism for failing over applications in a clustered computing system is provided. In an embodiment, the methodology is implemented by a high-availability failover mechanism. Upon detecting a failure of an application that is currently designated to be executing on a particular node of the system, the mechanism may attempt to failover the application onto a different node. The mechanism keeps track of a number of nodes on which a failover of the application is attempted. Then, based on one or more factors including the number of nodes on which a failover of the application is attempted, the mechanism may cease to attempt to failover the application onto a node of the system.

摘要： A cluster manager is configured to manage a plurality of copies of a mid-tier database as a mid-tier database cluster. The cluster manager may concurrently manage a backend database system. The cluster manager is configured to monitor for and react to failures of mid-tier database nodes. The cluster manager may react to a mid-tier database failure by, for example, assigning a new active node, creating a new standby node, creating new copies of the mid-tier databases, implementing new replication or backup schemes, reassigning the node's virtual address to another node, or relocating applications that were directly linked to the mid-tier database to another host. Each node or an associated agent may configure the cluster manager to behave in this fashion during initialization, based on common cluster configuration information. Each copy of the mid-tier database may be, for example, a memory resident database. Thus, a node must reload the entire database into memory to recover a copy of the database.
