摘要： A method, system, and computer program product for cost based analysis for data access in a database management system. In one approach, the method, system, and computer program product identifies data to access. A first cost for direct I/O storage access and a second cost for cache access are then determined for accessing the data. A comparison between the first cost and the second cost is then performed. Finally, a first portion of identified data is accessed based at least in part upon the comparison.

摘要： A session established for an application is suspended from an instance and later resumed on the server or a different server. When a session is suspended, its state is captured and persistently stored as a session image in a data repository, and the session is terminated. When the session is resumed, a new session is established on an instance, the session image of the session to resume is retrieved from the repository and restored to the newly established session. The suspension and resumption of a session may be initiated by an application, which may request the suspension and resumption of a session.
摘要翻译：为应用程序建立的会话从一个实例中暂停，然后在服务器或不同的服务器上恢复。当会话被暂停时，其状态被捕获并持久存储为数据存储库中的会话映像，并且会话终止。当会话恢复时，在一个实例上建立一个新的会话，从存储库中检索要恢复的会话的会话映像并恢复到新建立的会话。暂停和恢复会议可由申请人启动，申请可能要求暂停和恢复会议。

摘要： Described herein are various approaches that allow rules to be used to specify actions, that alleviate the complexity and burden of developing and maintaining rules in a rules-based messaging system, and that provide more efficient ways of evaluating rules. The approaches allow rules to specify user-defined transformation functions for transforming messages, to specify when and how to perform row migration, and to specify other types of actions. Rules are grouped into rule sets. Several types of rule sets, referred to as positive and negative rule sets, allow users to use rules that are less complex to develop and maintain. Rule sets are evaluated more efficiently by attempting to evaluate the rule set with less information than is needed to evaluate all the rules in the rule set. Also, the results of rules evaluations that are based on a set of values are cached for later retrieval.
摘要翻译：这里描述了允许规则用于指定动作的各种方法，其减轻了在基于规则的消息传递系统中开发和维护规则的复杂性和负担，并且提供了更有效的评估规则的方式。这些方法允许规则指定用于转换消息的用户定义的转换功能，指定何时以及如何执行行迁移，并指定其他类型的操作。规则分为规则集。称为正和负规则集的几种类型的规则集允许用户使用开发和维护不太复杂的规则。通过尝试使用比评估规则集中的所有规则所需的信息更少的信息来评估规则集，可以更有效地评估规则集。此外，基于一组值的规则评估结果被缓存以供以后检索。

摘要： Techniques allow a client to be switched from a session on a server to another session on another server in a way that is a transparent to the application for which the initial session was established. Thus, under transparent session migration, a client is switched between sessions without executing application instructions tailored to accomplish the migration. Instead, a client-side interface component, through which the application interacts with the server, handles details of migration, modifying the internal state of the client-side interface component to effect the same. Legacy applications do not have to be modified in order to institute techniques described herein.
摘要翻译：技术允许客户端以对初始会话建立的应用程序透明的方式从服务器上的会话切换到另一个服务器上的另一个会话。因此，在透明会话迁移下，客户端在会话之间切换，而不执行为完成迁移而定制的应用程序指令。相反，应用程序与服务器交互的客户端接口组件处理迁移的细节，修改客户端接口组件的内部状态来实现。传统的应用程序不需要修改，以便建立这里描述的技术。

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.
