此文承接上一篇文章，由于对单个控制文件恢复后，数据库里只有一个控制文件，所以要为数据库添加控制文件。
1）在nomount状态修改spfile文件。由于数据库里只有一个控制文件control03.ctl
先将control03.ctl拷贝后重命名为control01.ctl ，control02.ctl ，
SQL> conn system/yang as sysdba
Connected to an idle instance.
SQL> startup nomount
ORACLE instance started.
Total System Global Area 535662592 bytes
Fixed Size 1334380 bytes
Variable Size 138412948 bytes
Database Buffers 390070272 bytes
Redo Buffers 5844992 bytes
2）将控制文件添加到spfile文件里。
SQL> alter system set control_files=
2 'f:\app\yang\oradata\oracl\control01.ctl',
3 'f:\app\yang\oradata\oracl\control02.ctl',
4 'f:\app\yang\oradata\oracl\control03.ctl' scope=spfile;
System altered.
3）修改后应关闭数据库，重新启动到nomount状态时会用到修改过的spfile文件。
SQL> shutdown immediate
ORA-01507: database not mounted
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area 535662592 bytes
Fixed Size 1334380 bytes
Variable Size 138412948 bytes
Database Buffers 390070272 bytes
Redo Buffers 5844992 bytes
---出现没有料到的错误，不过重建过控制文件的话，ORA-00214 并不陌生。
ORA-00214: control file 'F:\APP\YANG\ORADATA\ORACL\CONTROL03.CTL' version 8281
inconsistent with file 'F:\APP\YANG\ORADATA\ORACL\CONTROL01.CTL' version 8279
--此错误说明CONTROL03.CTL' 比CONTROL01.CTL'的版本高，
SQL> shutdown immediate
ORA-01507: database not mounted
ORACLE instance shut down.
4）重新拷贝CONTROL03.CTL 并将其重新命名CONTROL01.CTL 再试一下。
SQL> alter system set control_files=
2 'f:\app\yang\oradata\oracl\control01.ctl',
3 'f:\app\yang\oradata\oracl\control02.ctl',
4 'f:\app\yang\oradata\oracl\control03.ctl' scope=spfile;
System altered.
SQL> shutdown immediate
ORACLE instance shut down.
SQL> startup mount
ORA-32004: obsolete and/or deprecated parameter(s) specified
ORACLE instance started.
Total System Global Area 535662592 bytes
Fixed Size 1334380 bytes
Variable Size 134218644 bytes
Database Buffers 394264576 bytes
Redo Buffers 5844992 bytes
ORA-00214: control file 'F:\APP\YANG\ORADATA\ORACL\CONTROL01.CTL' version 8295
inconsistent with file 'F:\APP\YANG\ORADATA\ORACL\CONTROL02.CTL' version 8279
--此错误说明CONTROL01.CTL' 比CONTROL02.CTL'的版本高，号码改变了，因为我实验的时候打开了数据库。关闭数据库再次修改，
SQL> shutdown immediate
ORA-01507: database not mounted
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area 535662592 bytes
Fixed Size 1334380 bytes
Variable Size 134218644 bytes
Database Buffers 394264576 bytes
Redo Buffers 5844992 bytes
Database mounted.
SQL> select name from v$controlfile;
NAME
--------------------------------------------------------------------------------
F:\APP\YANG\ORADATA\ORACL\CONTROL01.CTL
F:\APP\YANG\ORADATA\ORACL\CONTROL02.CTL
F:\APP\YANG\ORADATA\ORACL\CONTROL03.CTL
这一次成功。。
不知道我的方法有什么不妥，希望各位拍砖。。。。
