Abstract: A computer readable medium includes executable instruction to compare databases. The executable instructions are configured to identify when a segment of a first database is conditionally out of synchronization with a corresponding segment of a second database to establish a conditionally out of synchronization state at a first time. Executable instructions allow a latency period after the first time in which changes are made to the first database and the second database. Executable instructions also determine after the latency period whether the segment of the first database is in synchronization with the corresponding segment of the second database. Executable instructions also populate a resynchronization table, which is used by a replication mechanism to bring asynchronous rows into synchronization.

Abstract: A computer readable storage medium includes executable instructions to read source node transaction logs to capture transaction data, including local transaction data, global transaction identifiers and participating node data. The global transaction identifiers and participating node data are stored in target node queues. The target node queues are accessed to form global transaction data. Target tables are constructed based upon the local transaction data and the global transaction data.

Abstract translation: 计算机可读存储介质包括用于读取源节点事务日志以捕获交易数据（包括本地事务数据，全局事务标识符和参与节点数据）的可执行指令。 全局事务标识符和参与节点数据存储在目标节点队列中。 访问目标节点队列以形成全局事务数据。 目标表基于本地事务数据和全局事务数据构建。

Abstract: A computer readable storage medium includes executable instructions to receive a specification for requested data in a log based replication system where data changes are retrieved from both a transaction log and a database. It is determined that the requested data is compromised. A search for a data image containing the requested data is initiated. The data image is accessed to secure the requested data. The requested data is returned.
