摘要： Herein disclosed is a disk controller having a cache. This cache is so managed that a predetermined part composed of at least one of a plurality parts divided therefrom is initialized. In response to a request for cache activation from a host computer, the initializations of the cache are partly executed in a repeated manner, and a request for disk input/output is intermittently processed so that the whole initializations of a cache having a large capacity can be executed in parallel with the online process.Moreover, the logic failure of the cache and the hardware failure of a memory are divided. When the logic failure occurs, the use of the case is temporarily prohibited, and the whole initializations of the cache are executed automatically at the side of the disk controller without any intervention of a maintenance man so that the cache can be used again.
摘要翻译：这里公开的是具有缓存的盘控制器。对该高速缓冲存储器进行管理，使由其分割的多个部分中的至少一个构成的预定部分被初始化。响应于来自主计算机的缓存激活请求，高速缓存的初始化部分地以重复的方式执行，并且间歇地处理对盘输入/输出的请求，使得具有大容量的高速缓存的整个初始化可以与在线流程并行执行。此外，缓存的逻辑故障和存储器的硬件故障被划分。当发生逻辑故障时，暂时禁止使用该情况，并且高速缓存的整个初始化在磁盘控制器的一侧自动执行，而不需要维护人员的任何干预，以便可以再次使用高速缓存。

摘要： The present invention provides a performance monitoring method of a processing flow that, in a distributed object system, a processing is completed after going by way of processing of several objects through objects. A collector collects, as performance data, a receiving time of a message from the other object and a sending time of a message to the other for an object that becomes a measurement target on each computer. A manager puts received performance data together and calculates and displays a processing time of each object that constitutes a processing flow and a communication time between objects.

摘要： A method and system for detecting fraudulent data update of databases connected to a plurality of distributed computers in which a monitor computer connected via a network to the distributed computers detects fraudulent data update. The monitor computer collects initial data of the databases of the distributed computers via the network to generate parities for data at same storage fields and store them in a monitor database. Each time the databases connected to the distributed computers are updated, a parity update unit of the monitor computer generates new parities from data before and after the update and old parities and replaces the old parities stored in the monitor database by the new parities. At an auditing time, the monitor computer collects latest data of the distributed databases and generates parities which are compared with the corresponding parities already stored in the monitor database to detect an inconsistency of both parities.
