Oracle歸檔模式的運行模式
以下的文章主要講述的是正確的`啟動或是關閉Oracle歸檔模式的實際操作步驟,我們大家都知道Oracle數據庫運行於2種模式,主要實施Oracle歸檔模式(archivelog)與非歸檔模式(noarchivelog)。
Oracle歸檔模式可以提高Oracle數據庫的可恢復性,生產數據庫都應該運行在此模式下,歸檔模式應該和相應的備份策略相結合,只有歸檔模式沒有相應的備份策略只會帶來麻煩。
down normal或shutdown immediate關閉數據庫

base altered.
> alter database open;
base altered.
> archive log list;
