控制文件(Control Files)
控制文件跟蹤數(shù)據(jù)庫(kù)的物理組件,它是數(shù)據(jù)庫(kù)的重要功能。由于控制文件的重要性,Oracle建議控制文件應(yīng)該有多個(gè)副本。換言之,控制文件應(yīng)該有多個(gè)完全相同的副本。使用DBCA創(chuàng)建數(shù)據(jù)庫(kù)時(shí),三個(gè)控制文件自動(dòng)創(chuàng)建并互相同步。
(A control file tracks the physical components of the database. It is essential to the functioning of the database. Because of the importance of the control file, Oracle recommends that the control file be multiplexed. In other words, the control file should have multiple identical copies. For databases created with DBCA, three copies of the control file are automatically created and kept in sync with each other.)
如果控制文件失敗,那么你的數(shù)據(jù)庫(kù)將不可用。只要你有一個(gè)控制文件的副本,你可以關(guān)閉數(shù)據(jù)庫(kù)使用控制文件副本重新創(chuàng)建控制文件,然后重新啟動(dòng)數(shù)據(jù)庫(kù)。另外一種方法是從初始化參數(shù)的控制文件CONTROL_FILES中刪除損壞的控制文件表項(xiàng),使用其它的控制文件重新啟動(dòng)數(shù)據(jù)庫(kù)。
(If any control file fails, then your database becomes unavailable. As long as you have a control file copy, however, you can shut down your database and re-create the failed control file from the copy, then restart your database. Another option is to delete the failed control file from the CONTROL_FILES initialization parameter and restart your database with the remaining control files.) |
