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.

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： 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： Techniques are provided for managing a resource in a High Availability (HA) system. The techniques involve incrementing a count when a particular type of remedial action is performed on a resource, so that the count that reflects how often the particular type of remedial action has been performed for the resource. When it is determined that the resource has been in stable operation, the count is automatically reduced. After a failure, the count is used to determine whether to attempt to perform the particular type of remedial action on the resource. Examples of remedial actions include restarting the resource, and relocating the resource to another node of a cluster. By using the count, the system insures that a faulty resource does not get constantly “bounced”. By reducing the count when a resource has become stable, there is less likelihood that failure of otherwise stable resources will require manual intervention.
摘要翻译：提供了用于管理高可用性（HA）系统中的资源的技术。这些技术涉及在对资源执行特定类型的补救措施时增加计数，以便反映针对资源执行特定类型的补救措施的次数。当确定资源处于稳定运行状态时，计数自动减少。失败后，计数用于确定是否尝试对资源执行特定类型的补救措施。补救措施的示例包括重新启动资源，以及将资源重定位到群集的另一个节点。通过使用计数，系统确保错误的资源不会不断“反弹”。通过在资源变得稳定的情况下减少计数，则不太可能需要手动干预资源的稳定。

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 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.
