Description
TRANSLOG_Style defines the mode of the transaction log:- 0 = Circular: the log overwrites itself cyclically. Crash recovery only, no online restore of specific points.
- 1 = Archive: log extents are retained and must be archived through backups. Prerequisite for point-in-time restore.
- 2 = Linear: a fixed log file set like circular, but all logs are the same size and cannot be overwritten before they are archived.
Example configuration
TRANSLOG_Style=1
Notes & pitfalls
- Use archive mode only if a backup tool actually archives the logs – otherwise the log partition fills up.
- Changing the style requires a clean shutdown and usually a re-initialization of the log.
- For DAOS, online backups, and finer-grained restore scenarios, archive is common; for classic servers, circular is often sufficient.
- The value is set together with
TRANSLOG_Status,TRANSLOG_Path, andTRANSLOG_MaxSize.
