在STARTUP一資料庫時，發生如下錯誤：

SQL> conn /as sysdba

Connected to an idle instance.

SQL> startup

ORACLE instance started.

Total System Global Area 276824064 bytes

Fixed Size 778736 bytes

Variable Size 137371152 bytes

Database Buffers 138412032 bytes

Redo Buffers 262144 bytes

ORA-01102: cannot mount database in EXCLUSIVE mode

SQL> shutdown immediate

ORA-01507: database not mounted

ORACLE instance shut down.

GOOGLE一下，發現是lk<SID>文件造成的，該文件位於ORALCE_HOME下的dbs目錄下，馬上檢查該文件

[root@qa-oracle dbs]# fuser -u lkNDMSQA

「lkORACLE 這個文件」

lkNDMSQA: 6666(oracle) 6668(oracle) 6670(oracle) 6672(oracle) 6674(oracle) 6676(oracle) 6678(oracle) 6680(oracle) 6690(oracle) 6692(oracle) 6694(oracle) 6696(oracle) 6737(oracle) 6830(oracle)

果然該文件沒釋放，用fuser命令kill掉：

[root@qa-oracle dbs]# fuser -k lkNDMSQA

lkNDMSQA: 6666 6668 6670 6672 6674 6676 6678 6680 6690 6692 6694 6696 6737 6830

[root@qa-oracle dbs]# fuser -u lkNDMSQA

然後：

SQL> startup

ORACLE instance started.

Total System Global Area 276824064 bytes

Fixed Size 778736 bytes

Variable Size 137371152 bytes

Database Buffers 138412032 bytes

Redo Buffers 262144 bytes

Database mounted.

Database opened.
