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 :

[email protected]> 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 ...

[[email protected] ~]$ 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 :

[email protected]> conn / as sysdba

3. switch logfile

alter system switch logfile  ;

alter system switch logfile  ;

alter system switch logfile  ;

alter system switch logfile  ;

alter system switch logfile  ;

output :

[email protected]> alter system switchlogfile  ;

4. remove controlfile

rm /u02/oradat/bkt/control01.ctl

rm/u02/flash_recovery_area/bkt/control02.ctl

output :

[[email protected] ~]$ rm/u02/oradat/bkt/control01.ctl

[[email protected] ~]$ rm/u02/flash_recovery_area/bkt/control02.ctl

5. shutdown database

shutdown abort

output :

[email protected]> 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

[[email protected] ~]$ oerr ora 01207

01207, 00000, "file is more recentthan control file - old control file"

// *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.

看来不是立刻写入控制文件中。

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。

[email protected]> alter database backupcontrolfile to trace ;

Database altered.

alter :

Backup controlfile written to trace file/u01/apps/oracle/diag/rdbms/bkt/bkt/trace/bkt_ora_5933.trc

Completed: alter database backupcontrolfile to trace

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.
