Transaction logs

The Domino server has the ability to log transactions against one or more Lotus Notes databases (R5 or later). Because transactions cannot be logged against database versions earlier than Domino R5, these pre-R5 Lotus Notes databases are treated as unlogged databases.

All databases are logged by default when the following occurs:

The administrator enables transaction logging.
The database is in the Domino data directory.

All logged database transactions go into a single transaction log that consists of one or more files or extents.

Transaction logging can be either circular, linear, or archive style. When archive-style transaction logging is used, the archive log files can serve as the incremental backup for logged databases.

Note:

Transaction logging must be enabled to implement the recovery of logged databases.
