    • In reference, update, and insertion processing, the lock of an un-transferred object is released, and then the lock of a transferred object is set when the pointer is traced for transfer between objects to thereby improve the parallel execution capability of the reference, update, and insertion. At that time, the IS-mode (in the case of reference processing) or the IX-mode (in the case of update and insertion processing) is set at the starting of the processing, and the lock is released at the time of completion of the processing. Furthermore, in deletion processing, after the pointer to a deletion target is separated or replaced and all the processing that acquires the lock of an object group has been completed, the region of the deletion target object is released.

    • The system manages at least a database in multiple database storage units, and the database is duplicated for redundancy. The system maintains the database redundancy for security. The system enables the maintenance and reorganization of the database storage units without interrupting the on-going operations involving the access to the database storage units. The non-stop ongoing database access is available by allocating a pair of a main storage unit and an intermediate storage unit that maintains the substantially identical data. During certain predetermined operations, the main storage unit is being dedicating to the on-going transactions while the intermediate database storage unit is manipulated to contain data that corresponds to a specified time. For example, the content of the intermediate storage is subsequently copied or used to update another database. When the above duplication or incorporation is completed, the intermediate storage unit is updated for the transactions that have taken place during the above operations to be synchronized with the main storage unit.
    • 该系统至少管理多个数据库存储单元中的数据库,并且重复数据库以进行冗余。 系统维护数据库冗余以实现安全。 该系统能够维护和重组数据库存储单元,而不会中断正在进行的涉及对数据库存储单元的访问的操作。 可以通过分配一对主存储单元和维持基本上相同的数据的中间存储单元来获得不间断的数据库访问。 在某些预定操作期间,主存储单元被专用于正在进行的事务,而中间数据库存储单元被操纵以包含对应于指定时间的数据。 例如,中间存储器的内容随后被复制或用于更新另一个数据库。 当上述复制或并入完成时,中间存储单元被更新为在上述操作期间发生的与主存储单元同步的事务。

    • A grass collecting system having a grass collecting duct for transmitting grass clippings reaped by a mower to a swingable grass catcher. The grass collecting duct includes top and side plates for guiding grass clippings from the mower unit to the grass catcher. An outlet portion is defined by an end of a space surrounded by the top and side plates. The grass collection system also having a grass clippings discharge path for transmitting grass clippings received from the mower, from the outlet portion into the grass catcher, and a bottom plate unit disposed in the outlet portion that is swingable about a pivot shaft from a guide position to an upstanding position. The bottom plate unit has a shortening mechanism for shortening a distance between a forward end of the bottom plate unit projecting into the grass collecting duct and the pivot shaft.
    • 一种草收集系统,具有用于将由割草机收割的草屑传送到可摆放的捕草器的草集合管道。 草收集管包括顶部和侧板,用于将割草机从割草机引导到捕草器。 出口部分由由顶板和侧板围绕的空间的端部限定。 草收集系统还具有用于将从割草机接收的草屑从出口部分传送到草地捕集器中的草屑排放路径和设置在出口部分中的底板单元,该底板单元可绕枢轴从导向位置 到一个直立的位置。 底板单元具有缩短突出到草集合管道的底板单元的前端与枢轴之间的距离的缩短机构。
