在STARTUP一数据库时,发生如下错误:

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,发现是lk<SID>文件造成的,该文件位于ORALCE_HOME下的dbs目录下,马上检查该文件

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

“lkORACLE 这个文件”

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)

果然该文件没释放,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

然后:

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.

SQL>

数据库成功OPEN.
