Oracle数据库丢失控制文件的恢复四则
下文介绍了Oracle数据库中丢失控制文件的几种处理方法。
丢失单个控制文件
报错信息：

1、直接手动关闭了，其实数据库会自动的关闭。
shutdown abort ;
2、以下有两种方法
2.1、拷贝控制文件到原来的目录
cp/u02/flash_recovery_area/bkt/control02.ctl /u02/oradat/bkt/control01.ctl
2.2、启动到nomount后设置control_files的位置，将丢失的控制文件路径去掉
alter system setcontrol_files='/u02/flash_recovery_area/bkt/control02.ctl' scope=spfile ;
3.启动数据库即可
startup
下面介绍丢失所有控制文件的时候应该怎么做
使用冷备份的控制文件恢复
以下为详细的示例：
1. backup controlfile
show controlfile
copy
rman target /
backup controlfile current format '' ;
output :
sys@BKT> show parameter control
NAME TYPE VALUE
----------------------------------------------- ------------------------------
control_file_record_keep_time integer 7
control_files string /u02/oradat/bkt/control01.ctl,
/u02/flash_recovery_area/bkt/
control02.ctl
control_management_pack_access string DIAGNOSTIC+TUNING
--instance still running ...
[oracle@master ~]$ cp/u02/oradat/bkt/control01.ctl /tmp/control01.ctl
2. create tablespace
conn / as sysdba
define tbsname1='tbs1'
define tbsname2='tbs2'
define dfpath1='/u02/oradat/bkt/tbs101.dbf'
define dfpath2='/u02/oradat/bkt/tbs201.dbf'
create tablespace &tbsname1 datafile'&dfpath1' size 100m ;
create tablespace &tbsname2 datafile'&dfpath2' size 100m ;
create table &tbsname1 tablespace&tbsname1 as select * from all_objects ;
create table &tbsname2 tablespace&tbsname2 as select * from all_objects ;
select count(*) from &tbsname1 ;
select count(*) from &tbsname2 ;
alter tablespace &tbsname1 read only ;
output :
sys@BKT> conn / as sysdba

Table created.
sys@BKT> select count(*) from&tbsname1 ;

sys@BKT> alter tablespace &tbsname1read only ;
old 1: alter tablespace &tbsname1 read only
new 1: alter tablespace tbs1 read only
Tablespace altered.
sys@BKT>
3. switch logfile
alter system switch logfile ;
alter system switch logfile ;
alter system switch logfile ;
alter system switch logfile ;
alter system switch logfile ;
output :
sys@BKT> alter system switchlogfile ;
alter system switch logfile ;

alter system switch logfile ;
System altered.

4. remove controlfile
rm /u02/oradat/bkt/control01.ctl
rm/u02/flash_recovery_area/bkt/control02.ctl
output :
[oracle@master ~]$ rm/u02/oradat/bkt/control01.ctl
[oracle@master ~]$ rm/u02/flash_recovery_area/bkt/control02.ctl

Additional information: 3
5. shutdown database
shutdown abort
output :
sys@BKT> shutdown abort ;
ORACLE instance shut down.
6. using backup controlfile
--copy backup controlfile to thecontrolfile path which defined in the parameter .
cp /tmp/control01.ctl/u02/oradat/bkt/control01.ctl
cp /tmp/control01.ctl/u02/flash_recovery_area/bkt/control02.ctl
recover

// *Cause: The control file change sequence number in the data file is
// greater than the number in the control file. This implies that
// the wrong control file is being used. Note that repeatedly causing
// this error can make it stop happening without correcting the real
// problem. Every attempt to open the database will advance the
// control file change sequence number until it is great enough.
// *Action: Use the current control file ordo backup control file recovery to
// make the control file current. Be sure to follow all restrictions
// on doing a backup control file recovery.

如果及时的发现数据库未关闭，可以使用下面的命令将重建控制文件的脚本输出到trace文件中，方便后面的控制文件重建操作。

如果没有及时的发现已经丢失了所有的控制文件，这里重建控制文件需要知道一些额外的信息，包括redolog的位置、数据文件的位置还有字符集。（这里也可以使用snapshot控制文件来生成trace文件）

Continue applying redo log files until thelast log has been applied to the restored
data files, then cancel recovery byexecuting the following command:
CANCEL
The database indicates whether recovery issuccessful. If you cancel before all the
data files have been recovered to a consistentSCN and then try to open the
database, then you get an ORA-1113error ifmore recovery is necessary. You can
query V$RECOVER_FILEto determine whethermore recovery is needed, or if a
backup of a data file was notrestoredbefore starting incomplete recovery.
