    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： A method and system for implementing an improved access interface infrastructure is disclosed. In one approach, an access interface methods is directly supported by an application. The directly supported access interface method corresponds to an access interface implementation. Other access interface methods are transparently processed by being converted or mapped into a generic interface format, which is then translated into the directly supported format.

    摘要： An approach generates performance grades. A performance grade is a value or set of values that indicates the relative work performance offered by a resource, such as a server in a multi-node system, relative to other resources. Performance grades are used to dynamically allocate work within a multi-node computer system. For example, performance grades are used for connection-time balancing, and to direct a database connection request to a multi-node database instance that a performance grade indicates provides better performance. Performance grade deltas are generated that reflect the incremental change in performance grade for additional sessions or work. Performance deltas are used to direct incoming sessions, to more optimally balance workload, and to deal with logon storms where a large number of connect requests arrive in a very short time period.

    摘要： Various embodiments of the invention provide solutions to allow more sophisticated management of the relationship between a database and its clients (which can be, inter alia, end users, business applications, etc.). Merely by way of example, some embodiments can facilitate the management of work requests in a database, as well as the management of the quality-of-service in a database system. In some embodiments, an identification handle may be assigned to a database work request. A database management application can use the identification handle to identify the work request, as well, perhaps, as any related work requests. The identification handle may also identify the database (and/or an instance thereof) and/or a clustered database node, and the identification handle may be transmitted to a mid-tier application, e.g., to notify the mid-tier about the processing of the work request, changes in quality-of service, server availability, etc.

    摘要： A method and computer-readable medium for managing memory for complex objects returned from procedure calls are described. Memory for complex objects returned from procedure calls is allotted from memory pools, which are allocated on a “per-call” basis for complex objects. Complex objects allotted from different memory pools can have overlapping lifetimes. The memory used by the complex object is straightforwardly released by deallocating the memory pool. In one aspect, the memory management of complex objects is located in the called procedures, which may be an automatically generated client stub routine for a remote procedure call.
