摘要： An approach efficiently and dynamically places services within a multi-node system when expanding or contracting services, that is, increasing and decreasing the number of instances that host a service. Service placement decisions are made in a way that accounts for performance and availability requirements of both the service being placed and other services.
摘要翻译：一种方法在扩展或缩小服务时，将服务置于多节点系统内，即增加和减少托管服务的实例数量。服务放置决策的方式是考虑到正在放置的服务和其他服务的性能和可用性要求。

摘要： Approaches are used for efficiently and effectively managing the dynamic allocation of resources of multi-node database systems between services provided by the multi-node database server. A service is a category of work that is hosted on the database server. The approaches manage allocation of resources at different levels. For services that use a particular database, the performance realized by the services is monitored. Resources assigned to the database are allocated between these services to ensure performance goals for each are met. Resources assigned to a cluster of nodes are allocated between the databases to ensure that performance goals for all the services that use the databases are met. Resources assigned to a farm of clusters are assigned amongst clusters based on service level agreements and back-end policies. The approach uses a hierarchy of directors to manage resources at the different levels.

摘要： Techniques are provided for creating dynamic connections to objects on remote database clusters. Service-to-instance mapping information is provided to a listener process for a cluster database. The service-to-instance mapping indicates the current provider instance(s) of each object within the cluster database. To establish a connection to a remote object, a sending process uses an object link. The object link identifies the desired destination object, but not the provider instance of the object. The object link also contains a authentication information and other connection information that exists in regular database links. The global listener for the cluster database uses the service-to-instance mapping to determine which instance is the current provider of the specified object, and dynamically distinguishes the appropriate database instance as the endpoint of the connection.

摘要： A system and method is disclosed that allows resources to be shared among multiple entities, but which can appropriately release system resources after the failure or shutdown of the calling entity. In one approach, a monitoring entity is available to check for session failures. If a session failure is detected, the session is identified in a shared list that is accessible to other related entities. The related entities can be configured to piggyback a message to an appropriate node to kill, shutdown, or release resources associated with the failed session. Alternatively, a related entity can be specifically initiated to send a message to the appropriate node to kill, shutdown, or release the resources.

摘要： A method and apparatus for managing sessions across the nodes of a multi-node system is provided. When a session is first initiated on any node of a multi-node system, a global session identifier is assigned to the session. The global session identifier uniquely identifies the session relative to all other sessions managed by the multi-node system. A session monitor may use the global session identifier to collect and store cumulative statistics about the activity of the session, regardless of which node of the multi-node system is currently managing the session, since the global session identifier uniquely identifies the session relative to all other sessions managed by the multi-node system. As a session may be uniquely identified across the lifetime of the session, the session state may be cleaned-up when the session ceases to be maintained, and the activity of the session during its lifetime may be analyzed.
摘要翻译：提供了一种用于在多节点系统的节点上管理会话的方法和装置。当会话首次在多节点系统的任何节点上启动时，全局会话标识符被分配给该会话。全局会话标识符唯一地标识相对于由多节点系统管理的所有其他会话的会话。会话监视器可以使用全局会话标识符来收集和存储关于会话的活动的累积统计信息，而不管多节点系统当前正在管理该会话的哪个节点，因为全局会话标识符唯一地标识相对于所有会话的会话由多节点系统管理的其他会话。由于可以在会话的整个生命周期中唯一地识别会话，所以可以在会话停止维持时清除会话状态，并且可以分析会话在其生命期内的活动。

摘要： A system and method for facilitating a remote procedure call (RPC) using an auto-evolvable RPC interface or record type (an “RPC structure”). Each field of an auto-evolvable RPC structure includes a version number and a default value. During a negotiation process, a client and a server exchange their highest version numbers, thereby indicating their RPC capabilities to each other. A higher or more recent version number may indicate a more recent release of the application comprising the RPC. During an RPC, when the client sends a structure to the server, or vice versa, and it has a more recent version, it may omit one or more fields that are not in the recipient's version. When the server receives a structure from the client, or vice versa, and it has a more recent version, it may populate an extra field (not in the sender's version) with its default value.
