    • PROBLEM TO BE SOLVED: To provide a transactional replication system. SOLUTION: In this system, each replicated command applies to a single row identified by the primary key, and replicated commands are dispatched among multiple connections by hashing of primary key from a single command queue to ensure that changes to the same data row are always dispatched to the same connection to maintain the order of commands as originally occurred on a publisher. All connections commit their transactions at the same time in a coordinated fashion without a two phase commit. Retry logic based on a logical sequence number is used to reapply commands from any connection that fails to commit. COPYRIGHT: (C)2004,JPO&NCIPI
    • 要解决的问题:提供事务复制系统。

      解决方案:在此系统中,每个复制命令都适用于主键标识的单个行,复制命令通过从单个命令队列中的主键进行散列来确保对相同数据行的更改进行多个连接之间的调度 总是被分派到同一个连接,以保持最初发生在发布者上的命令顺序。 所有连接以协调的方式同时提交其事务,而不进行两阶段提交。 基于逻辑序列号的重试逻辑用于重新应用任何无法提交的连接的命令。 版权所有(C)2004,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a system and a method for improved client and server communication, more particularly, an improved protocol to be used for communication between a client and a server in an electronic mail environment. SOLUTION: An electronic mail server may provide an optimum message body for an electronic mail message, may transfer an entire data object if requested property (group of properties) is not properly defined in the data object, may provide progress data to be used in tracking download progress, and may transmit error information if the data object has any error. Electronic mail changes generated in the component in some electronic mail server may be optimized in the component of another electronic mail server, and the electronic mail server may maintain a table of changes occurring in a folder in an associated data store and may notify a registered electronic mail component about changes which has occurred in the table.
