标题: 手动升级数据库时注意原数据库需要shutdown
在使用手动升级数据库时，出现了这样的报错：

SQL> startup upgrade

ORACLE instance started.

Total System Global Area 1586708480 bytes

Fixed Size 2253624 bytes

Variable Size 973081800 bytes

Database Buffers 603979776 bytes

Redo Buffers 7393280 bytes

ORA-00205: error in identifying control file, check alert log for more info

于是查看alert日志，发现：
ORA-00210: cannot open the specified control file
ORA-00202: control file: '/u01/app/oradata/app/control01.ctl'
ORA-27086: unable to lock file - already in use

控制文件处于使用中，这才想起，低版本的源库没有shutdown

于是先将源库停掉：
SQL> shutdown immediate

再重新进行升级：
ORACLE instance started.

Total System Global Area 1586708480 bytes
Fixed Size                2253624 bytes
Variable Size          973081800 bytes
