    • A transaction managing system is described in which transaction commands must be routed to appropriate resource managers. The transaction managing system first determines the identity of the target resource from the transactions commands, and compares this with all the resources that it knows it manages itself. If the target resource is managed by the transaction processing system itself, then the transaction command is passed to a resource manager within the transaction managing system itself. If the transaction managing system does not recognise the resource then it sends a query message to each external resource manager to determine if any of these recognise the resource. If one of the external resource managers send an ownership message back to the transactions managing system admitting ownership of the target resource then the transaction command is passed to that external resource manager for processing.
    • 描述了事务管理系统,其中事务命令必须被路由到适当的资源管理器。 事务管理系统首先从事务命令确定目标资源的身份,并将其与其自身管理的所有资源进行比较。 如果目标资源由事务处理系统本身管理,则事务命令被传递给事务管理系统本身的资源管理器。 如果事务管理系统不识别资源,则它向每个外部资源管理器发送查询消息,以确定其中任何一个是否识别该资源。 如果一个外部资源管理器将所有权消息发送回交易管理系统,以允许目标资源的所有权,那么事务命令将传递给该外部资源管理器进行处理。
