摘要： One or more files of an application are obtained and configured as a virtual storage volume. An application package is generated by encrypting, using a key, the one or more files configured as a virtual storage volume. A license generation module generates a license including both a usage policy for the application and the key. A computing device, to run the application, obtains and attempts to authenticate the application package. If the application package is authenticated, then a license associated with the application package is obtained and at least part of the application package is decrypted using the key in the license. A virtual storage volume that includes the application is mounted, and the application is executed in accordance with the usage policy in the license. However, if the application is not authenticated, then the application is not executed.

摘要： An efficient database cluster system that uses multiple stand-alone database servers with independent datasets to deliver higher processing speed and higher service availability at the same time with zero transaction losses. In one embodiment, a dynamic serializing transaction replication engine with dynamic load balancing for read-only queries is implemented. In another embodiment, a non-stop database resynchronization method that can resynchronize one or more out-of-sync databases without shutting down the cluster automatic database resynchronization process is implemented. In yet another embodiment, an embedded concurrency control language is implemented in the replication engine for precise control of the dynamic serialization engine for optimal processing performance. In yet another embodiment, a zero-downtime gateway failover/failback scheme using a public Internet Protocol (IP) is implemented. In yet another embodiment, a horizontal data partitioning method for load balancing update queries is implemented.
摘要翻译：一个高效的数据库集群系统，使用具有独立数据集的多个独立数据库服务器，同时实现零交易损失，提供更高的处理速度和更高的服务可用性。在一个实施例中，实现了具有用于只读查询的动态负载平衡的动态序列化事务复制引擎。在另一个实施例中，实现了可以在不关闭集群自动数据库重新同步过程的情况下重新同步一个或多个不同步数据库的不间断数据库重新同步方法。在另一个实施例中，在复制引擎中实现嵌入式并发控制语言，用于精确控制动态序列化引擎以获得最佳处理性能。在另一个实施例中，实现使用公共网际协议（IP）的零停机时间网关故障切换/故障恢复方案。在又一个实施例中，实现了用于负载平衡更新查询的水平数据分割方法。

摘要： This invention concerns providing a fault tolerant data service using multiple redundant off-the-shelf-database servers connected by low bandwidth networks. The data service continues operation regardless partial processing hardware failures, network failures, operating system failures and incidental database malfunctions. A database gateway automatically replicates database communication packets and monitors the wellness of communication networks and supporting database servers. It can quickly identify a unstable connection or a database server, thus providing highly reliable data service to all clients. An algorithm is disclosed to accomplish these tasks using minimal original client data.
