Abstract: A method, apparatus, and article of manufacture for providing transaction control for a computer-implemented database management system. The database management system manages one or more databases, wherein each of the databases contains one or more documents and each document contains one or more objects. The database management system also supports a file cache for those databases. A transaction control system provides transaction control for the databases, documents, and objects managed by the database management system, wherein the transaction control system monitors and controls the file cache to ensure that modified objects are stored on a data storage device in manner that reflects an accurate status for a log file maintained by the transaction control system.
