摘要： A system, method, computer program and system for suspending a result set and continuing from a suspended result set for a cursor is disclosed. The rows from a row source corresponding to the cursor result set are suspended into storage so that when a fetch is requested the data can be sent (continued) from the suspended storage and does not depend on the original cursor row source or session to be available.

摘要： A method and system for implementing scrollable cursors is described. A multi-tier caching structure is maintained, in which a partial result set is cached at the client computer and a more-complete result set is cached at the server computer. If the cursor is scrolled in either the forward or backward directions, the partial result set cached at the client computer is first checked to see if requested data is present. If so, then the requested data is fetched from the client cache and the current position of the cursor is moved to the appropriate position in the result set. If the requested data is not present in the client cache, then those data items are fetched from the cache at the server computer.

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 method and mechanism for dynamically changing the logical path of a state machine to avoid conflicts or problems is provided. A toggle state is employed for a state machine that allows dynamic changes in the computation path of a state machine. By analyzing the expected response state of a remote state machine, toggle states can be inserted in the path of a local state machine to avoid conflicts. This approach can be advantageously employed to reduce or prevent half-duplex violations for communications between applications on multiple computing nodes.
