    摘要： Disclosed are improved methods, systems, and mediums for cursor sharing and cursor pruning. According to some approaches, existing child cursors are distinguished using a cursor sharing criteria node structure. A sharing criteria node (also referred to as a “diagnostic” node) is created when a sharing criteria mismatch/failure happens. The node contains information about why the child cursor could not be shared and also information that can be used to quickly re-evaluate this sharing criterion in the future.

    摘要： A method and apparatus for efficiently managing cached objects is provided. A mapping is a typed relationship between cached objects. A base object contains content, and a mapped object is mapped to a base object when there is a particular relationship between the mapped object and the base object. The type of mapping defines how the objects in the relationship are treated when the mapped object is created, read, or written. At creation time, the mapping type may define how the mapping relationship is recognized. Sometimes recognizing a relationship requires establishing equivalence between the objects. At read and write time, the mapping type may define on which object a mutual exclusion lock is held, which content is returned or which object's content is updated. A wide range of applications can benefit from enhanced object caching performance, and in addition, application may define application-specific semantics on mapping types as well.

    摘要： Methods, devices, and storage media are provided for preserving the context of a server-client session. A server generates an initial context and a context for each user command executed in a first session and sends context to a client with the return for each command. The context describes software, session state, returned data, and/or hardware characteristics of a server-side environment for the first session. The client receives and stores the context with each user command. Upon determining that the database session should be rebuilt in the second session, the client sends initial context. A server for the second session receives the initial context and determines whether commands should be replayed in the second session. If commands are replayed, the server validates that server environment and client-visible results for each command in the second session match that from execution in the first session using the context for that command.
