SQL Server
Transaction safety is the attribute that controls the operating mode of the session. At any time, however, the database owner can change the transaction safety. By default, the level of transaction safety is set to FULL (synchronous operating mode).
Turning off transaction safety shifts the session into asynchronous operating mode, which maximizes performance. If the principal becomes unavailable, the mirror stops but is available as a warm standby (failover requires forcing service with possible data loss).
Connect to the principal server.
Issue the following Transact-SQL statement:
ALTER DATABASE <database> SET PARTNER SAFETY FULL
where <database> is the name of the mirrored database.
Connect to the principal server.
Issue the following statement:
ALTER DATABASE <database> SET PARTNER SAFETY OFF
where <database> is the mirrored database.
