2.分析原因

到$ORACLE_HOME/dbs下找到lk開頭文件，這個(gè)錯(cuò)誤主要是lk<SID>文件造成的

它的主要作用是說明DATABASE MOUNT上了,不用在MOUNT了；DATABASE UNMOUNT 后會(huì)自動(dòng)刪除,但異常情況時(shí)文件存在的話，即使數(shù)據(jù)庫(kù)已經(jīng)停掉，系統(tǒng)也會(huì)認(rèn)為數(shù)據(jù)庫(kù)已經(jīng)mount了

$ cd $ORACLE_HOME/dbs

$ ls -l

3.解決方法

用fuser命令kill掉占用lkITSYS1文件的進(jìn)程

$ fuser -k lkITSYS1

lkITSYS1:  5701814 5767372 5832954 6946854 7209198 7667712 7930062 8323164 8388624 8847426 9306156 9633968 9699564 9895986 16187422

$ fuser -u lkITSYS1
