    • A data set typically does not stagnate and remain the same size over time. The capabilities of hardware (e.g., servers and storage devices) also do not stagnate and remain the same. A date set is often repartitioned to accommodate changes in size of the data set and/or changes in hardware capability. Hundreds or thousands of writes may be performed on the data set (e.g., database, directory, etc.) every second. So, even a few seconds of downtime are unacceptable. Instead of taking the data set offline, the data set can be repartitioned while still allowing access to the data set (“repartitioning live data”). Live data can be repartitioned by establishing update or replication queues for the new partitions while servicing write requests and read requests with the old partitions. After the data has been migrated, the update queues are drained to ensure data integrity.
    • 数据集通常不会停滞并且随时间保持相同的大小。 硬件(例如,服务器和存储设备)的功能也不会停滞并保持不变。 日期集经常被重新分区以适应数据集大小的变化和/或硬件能力的变化。 每秒可以在数据集(例如,数据库,目录等)上执行数以千计的写入。 因此,甚至几秒钟的停机时间是不能接受的。 而不是使数据集脱机,数据集可以重新分区,同时仍然允许访问数据集(“重新分配实时数据”)。 可以通过为新分区建立更新或复制队列来重新分配实时数据,同时为旧的分区处理写入请求和读取请求。 数据迁移后,排队更新队列以确保数据的完整性。

    • Methods, systems and computer program products for management of application programs on a network including a server supporting client stations are provided. The server provides applications on-demand to a user logging in to a client supported by the server. Mobility is provided to the user and hardware portability is provided by establishing a user desktop interface responsive to a login request which presents to the user a desktop screen through a web browser interface which accesses and downloads selected application programs from the server responsive to a request from the user on the user desktop screen at the client. The application program is then provided from the server and executed at the client. The application program may further be customized to conform to the user's preferences and may also provide for license use management by determining license availability before initiating execution of the application program. Finally, software distribution and installation may be provided from a single network management server.
