摘要： A continuous set of committed transactions can be lost without destroying the integrity of the database, by deferring the writing of the database pages stored in cache to the database on stable storage. A waypoint tracks a point in the transaction log following which transactions have not been applied to the database on stable storage and thus records after the waypoint are not needed for recovery to a consistent database. When there is a failover of an active database on Node A to a passive database on Node B, log records are compared starting with the most current and moving backwards and the point at which divergence in the log occurs is determined. When the lost portion of the log occurs after the point indicated by after the waypoint, the database is recoverable by log-based incremental reseed.

摘要： Architecture for detecting lost writes using timestamps. During a replication process, lost writes in data replicated from a stream can be detected by noting discrepancies between the timestamps of data in the replica and timestamps associated with the corresponding data from the source in original data store. A lost write either in the original data store or in the replica data store can be inferred by comparing these timestamps with the timestamps in a number of other replica data stores. Additionally, check entries can be added to the replicas by the original data store to allow expanded comparison between recently modified data and the source data in the original data store. The check entries can be added to the replication journal after a time delay, thereby increasing effectiveness of the check by decreasing the likelihood that caching in the hardware will defeat the test.
摘要翻译：用于使用时间戳检测丢失的写入的架构。在复制过程中，可以通过记录副本中的数据的时间戳和与来自原始数据存储中的源的相应数据相关联的时间戳之间的差异来检测从流复制的数据中的丢失写入。可以通过将这些时间戳与许多其他副本数据存储中的时间戳进行比较来推断在原始数据存储器中或复制数据存储器中的丢失写入。此外，检查条目可以由原始数据存储添加到副本，以允许最近修改的数据与原始数据存储中的源数据之间的扩展比较。检查条目可以在延迟之后添加到复制日志中，从而通过减少硬件中缓存失败的可能性来提高检查的有效性。

摘要： A method for calculating a block cache size for a host process or application on a computer based at least upon virtual memory page evictions and/or virtual memory page reclamations for the computer. A virtual memory page eviction is the act of removing the contents of a physical memory page for the purpose of loading it with the contents of another virtual memory page. A virtual memory page reclamation is the return of a page to a working set that was previously removed by the operating system due to memory constraints. The page must not have been evicted. Additional fundamental properties of the application and the computer may be used, such as available physical memory on the computer, total physical memory, and block evictions. A block eviction is the act of removing the contents of a block from the block cache for the purpose of loading it with new contents.
