At the start of a database mirroring session , the database is in the synchronizing state 在數(shù)據(jù)庫鏡像會話開始時,數(shù)據(jù)庫處于synchronizing狀態(tài)。
If transaction safety is off , some data loss is always possible , even in the synchronized state 如果關閉事務安全性,則即使處于synchronized狀態(tài),也總可能丟失某些數(shù)據(jù)。
Manual failover requires transaction safety to be set to full and the database to be in the synchronized state 手動故障轉移要求將事務安全設置為full ,并且數(shù)據(jù)庫處于synchronized狀態(tài)。
If transaction safety is on , automatic failover and manual failover are both supported in the synchronized state , there is no data loss after a failover 如果啟用事務安全性,則synchronized狀態(tài)同時支持自動故障轉移和手動故障轉移,并且在故障轉移后不會丟失數(shù)據(jù)。
Forces database service to the mirror database after the principal server fails with the database in an unsynchronized state or in a synchronized state when automatic failover does not occur 在主體服務器因數(shù)據(jù)庫處于不同步狀態(tài)而失敗后,強制鏡像數(shù)據(jù)庫提供服務。
From vibrating torque equations of shaker ' s exciting shafts , the self - synchronizing condition and synchronizing state stability condition of balanced elliptical shakers excited by two - shaft self - synchronizing are obtained 從振動篩偏心軸的振動力矩方程出發(fā),導出了雙軸自同步平動橢圓振動篩的自同步條件和穩(wěn)定運轉條件。
