ORA-01102: cannot mount database in EXCLUSIVE mode处理方法

在STARTUP一数据库时，报ORA-01102错误：

SQL> startup

ORACLE instance started.

Total System Global Area 536870912 bytes

Fixed Size 1322944 bytes

Variable Size 166187072 bytes

Database Buffers 369098752 bytes

Redo Buffers 262144 bytes

ORA-01102: cannot mount database in EXCLUSIVE mode

查了下可能是由于数据库异常关闭,用于锁定内存的方件lk<SID>没有删除造成的.

1.先关闭数据库

SQL> shutdown immediate

ORA-01507: database not mounted

ORACLE instance shut down.

2.检查$ORACLE_HOEM/dbs目录,果然有lkEMREP文件，检查该文件

[oracle@cfbgc dbs]$ fuser -u lkEMREP

lkEMREP: 2744(oracle) 2746(oracle) 2748(oracle) 2750(oracle) 2752(oracle) 2754(oracle) 2756(oracle) 2758(oracle) 2786(oracle) 2788(oracle) 2790(oracle) 2792(oracle) 2794(oracle) 10437(oracle) 10672(oracle) 10674(oracle) 10676(oracle)

3.kill掉所有进程

[oracle@cfbgc dbs]$ fuser -k lkEMREP

lkEMREP: 2744 2746 2748 2750 2752 2754 2756 2758 2786 2788 2790 2792 2794 10437 10672 10674 10676

再次查看，已经没有进程了：

[oracle@cfbgc dbs]$ fuser -u lkEMREP

4.重新启动数据库

SQL> startup

ORACLE instance started.

Variable Size 166187072 bytes
