    • Disclosed is a data processing-implemented method, a data processing system, and an article of manufacture for modifying a query during compilation of the query. The query includes a request for an element of data from a table in a database and parameters identifying the requested element. The data processing-implemented method includes determining available information from parameters for locating a classification of the requested element and a classification associated with the query, the requested data classification controlling access to the requested element according to the query associated classification, requesting a suggested action from an external system for obtaining a comparison of the requested data classification and the query associated classification based on the available information, receiving the suggested action from the external system responsive to the sent request, and incorporating the suggested action into the query, the suggested action effecting comparison of the requested data classification with the query associated classification.
    • 公开了一种数据处理实现的方法,数据处理系统和用于在查询的编译期间修改查询的制品。 该查询包括对来自数据库中的表的数据元素的请求以及标识所请求元素的参数。 数据处理实现的方法包括从用于定位所请求的元素的分类和与查询相关联的分类的参数确定可用信息,所请求的数据分类根据查询关联分类来控制对所请求的元素的访问,请求建议的动作 用于基于所述可用信息获得所请求的数据分类和所述查询关联分类的比较的外部系统,响应于所发送的请求从所述外部系统接收所述建议的动作,并将所述建议的动作合并到所述查询中,所述建议的动作 请求的数据分类与查询关联分类的比较。

    • A method and system for caching dynamic SQL statements and their sections at different nodes in a multiple node Relational Database Management System (RDBMS) while maintaining cache and application integrity across all nodes. Each node in the RDBMS having a global cache shared by all applications on that node. One of the nodes in the RDBMS being a catalogue node which controls access to a database. The catalogue node maintaining a list of participating nodes that have requested access to the database controlled by the catalogue node. The list of participating nodes being used to notify each participating node of any changes to the database that may affect the validity of a dynamic SQL statement stored in the global cache of the node.
    • 一种用于在多节点关系数据库管理系统(RDBMS)中的不同节点处缓存动态SQL语句及其部分的方法和系统,同时在所有节点上保持缓存和应用程序完整性。 RDBMS中的每个节点都具有由该节点上的所有应用程序共享的全局高速缓存。 RDBMS中的一个节点是控制对数据库的访问的目录节点。 目录节点维护已请求访问由目录节点控制的数据库的参与节点的列表。 参与节点的列表用于通知每个参与节点对数据库的任何可能影响存储在节点的全局缓存中的动态SQL语句的有效性的任何更改。

    • A monitoring of a server system during an execution of a server system processing logic, includes: during collection and storage of operational metrics by a given thread in a thread-local memory, determining that a checkpoint within the server system processing logic is reached; determining whether a threshold number of checkpoints have been encountered by the given thread; in response to the threshold number of checkpoints having been encountered, determining whether a threshold time interval since a last rollup of the collected operational metrics has been exceeded; and in response to the threshold time interval being exceeded, performing a rollup of the collected operational metrics from the thread-local memory to an accumulation point in a shared memory, where the accumulation point stores aggregated operational metrics from a plurality of threads.
    • 在执行服务器系统处理逻辑期间对服务器系统的监视包括:在由线程本地存储器中的给定线程收集和存储操作指标期间,确定到达服务器系统处理逻辑内的检查点; 确定给定线程是否遇到阈值数量的检查点; 响应于已经遇到的检查点的阈值数量,确定是否已经超过了所收集的操作度量的最后一次累积的阈值时间间隔; 并且响应于所述阈值时间间隔被超过,从所述线程本地存储器到所述共享存储器中的累积点执行所收集的操作度量的汇总,其中所述累积点存储来自多个线程的聚合操作度量。
