    • A method for of accelerating database log hardening using specific per block data protection and damage control is provided. A per write specification is implemented to determine when database log data is mirrored synchronously or asynchronously. Synchronous mirroring is performed upon reaching a predetermined threshold, based on one or more parameters such as transaction value, both individual and cumulative, and the quantity of data written since the last synchronous mirroring. As data is added to the database log, it is written specifying asynchronous mirroring to the primary log file. Once a threshold is met, a write specifying synchronous mirroring is performed to both the primary and secondary log files, thereby hardening the log file in both primary and secondary storage subsystem.
    • 提供了一种使用特定的每个块数据保护和损坏控制来加速数据库日志硬化的方法。 实现每个写入规范以确定数据库日志数据何时同步或异步镜像。 基于诸如事务值,个人和累积的一个或多个参数以及从上次同步镜像以来写入的数据量,在达到预定阈值时执行同步镜像。 随着数据被添加到数据库日志中,它被写入指定主日志文件的异步镜像。 一旦满足阈值,就会对主日志文件和辅助日志文件执行写入指定同步镜像,从而加强主存储子系统和辅助存储子系统中的日志文件。

    • A method, system and computer program product for responding to error events are provided. The method includes: detecting a detected error event while executing a computer readable program; looking for a predefined response to the detected error event in a modifiable error event response data structure; validating the modifiable error event response data structure; and responding to the detected error event according to the predefined response if the modifiable error event response data structure is valid and if the modifiable error event response data structure includes the predefined response.
    • 提供了一种用于响应错误事件的方法,系统和计算机程序产品。 该方法包括:在执行计算机可读程序的同时检测检测到的错误事件; 在可修改的错误事件响应数据结构中寻找对检测到的错误事件的预定义响应; 验证可修改的错误事件响应数据结构; 以及如果所述可修改的错误事件响应数据结构有效并且所述可修改的错误事件响应数据结构是否包括所述预定响应,则根据所述预定响应来响应所检测的错误事件。

    • A method for of accelerating database log hardening using specific per block data protection and damage control is provided. A per write specification is implemented to determine when database log data is mirrored synchronously or asynchronously. Synchronous minoring is performed upon reaching a predetermined threshold, based on one or more parameters such as transaction value, both individual and cumulative, and the quantity of data written since the last synchronous minoring. As data is added to the database log, it is written specifying asynchronous minoring to the primary log file. Once a threshold is met, a write specifying synchronous minoring is performed to both the primary and secondary log files, thereby hardening the log file in both primary and secondary storage subsystem.
