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： An approach migrates database sessions from a database server on which performance and resource availability requirements are not being met to another database server. Because workload is removed from the database server not meeting these requirements, improved performance there is promoted. Furthermore, the approach switches the users in a way that attempts to keep performance and resource availability levels at the database server receiving the database sessions within goals for performance and resource availability.

摘要： An approach provides for recovery of message driven directors responsible for dynamically allocating resources within a multi-node database system. The receipt of a message, the action taken in response to it, and other messages sent in furtherance of the action, are performed within a single transaction. In this way, the messages and other data are left in a state consistent with the message and action taken in response being fully processed or not processed at all. A standby director, stepping in for a crashed director, inherits a state consistent with where a crashed director last successfully completed an action. The approach insulates directors from the special perils of performing high latency actions by delegating the performance of such actions to a job, (i.e. another process).
摘要翻译： 一种方法用于恢复负责在多节点数据库系统内动态分配资源的消息驱动的主管。 在单个事务中执行消息的接收，响应于该动作的动作以及发起促进动作的其他消息。 以这种方式，消息和其他数据保持与消息一致的状态，并且响应中采取的动作被完全处理或根本不处理。 一名备用导演踩踏一名坠毁的导演，继承了一个与坠毁导演最后一次成功完成行动的地方一致的状态。 这种方法使董事们免受执行高延迟行动的特殊危险，将这些行为的表现委托给一个工作（即另一个过程）。

摘要： Techniques for authenticating users when an operation requested by a user in one of the systems of a distributed system is redirected to another system of the distributed system. The user is authenticated in the usual way to the one system but is authenticated to the other system for the redirected operation by an authentication proxy in the first system. The fact that the authentication proxy is providing a redirected operation means that the user who requested the operation has been authenticated to the one system. The other system is thus able to authenticate the user for the redirected operation with different authentication information than would otherwise be required. An example of how the techniques are used is a distributed database system where one of the database systems in the distributed system is a cache for another of the database systems.
