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

Database mounted.
Database opened.
