    摘要: A fault-tolerant method and system for processing global transactions in a distributed database system. If a fault occurs in the distributed database system, a transaction management system will suspend the processing of a transaction and renew it when the fault is remedied. The transaction management system identifies one or more sites in the distributed database system that contain data needed for a global transaction and divides each transaction into subtransactions for processing at one or more identified sites. If a fault occurs in the distributed database system, the transaction management system maintains the status of each subtransaction. When a fault in the distributed database system is corrected, the transaction management system updates the status of each subtransaction and restarts processing of the transactions.

    摘要翻译: 用于处理分布式数据库系统中的全局事务的容错方法和系统。 如果在分布式数据库系统中出现故障,事务管理系统将暂停处理事务,并在纠正故障时对其进行更新。 事务管理系统识别分布式数据库系统中包含全局事务所需的数据的一个或多个站点,并将每个事务划分为用于在一个或多个标识站点处理的子事务处理。 如果分布式数据库系统发生故障,则事务管理系统维护每个子事务的状态。 当分布式数据库系统中的故障得到纠正时,事务管理系统将更新每个子事务的状态,并重新启动事务的处理。
