重建控制文件 recreate control file

原创 Linux操作系统 作者:tengrid 时间:2011-01-21 15:42:50 0 删除 编辑

简单总结如下:
1) 启动到mount
2) 执行Alter database backup controlfile to trace;
3) 找到第2步生成的trace文件,并作相应修改. 只保留创建语句
4) shutdown并启动到nomount, 执行创建语句
5) 启动到mount
6) 执行下面脚本,进行恢复
$more recover_db.sh
#!/bin/bash
source /home/oracle/.bash_profile
cd `dirname $0`

sqlplus / as sysdba  <startup mount;
recover database noparallel;
auto
EOD
7) 执行ALTER SYSTEM ARCHIVE LOG ALL;
8) ALTER DATABASE OPEN;
9) 注册临时文件  (语句在第2步生成的trace文件末尾)
ALTER TABLESPACE TEMP2 ADD TEMPFILE '+DATA1/isddw/datafile/temp2_01' REUSE;
....

Symptoms
ORA-1122 :database file %s failed verification check
ORA-1110 : datafile :
ORA-1207: ORA 1207 file is more recent than control file

Cause
The information in this file is inconsistent with information from the control file.
The datafile header CHECKPOINT count is beyond the controlfile CHECKPOINT count.

Solution
1.Mount the database
SQL>Startup mount

2. trace the control file

SQL> Alter database backup controlfile to trace;

3. Create a control file creation script. from the tracefile generated in user_dump_dest.

Use the Noresetlogs option

4.shutdown the database and start it NOMOUNT mode

SQL>shutdown abort
SQL>startup NoMount

5.Create the control file

Use the script. generated by the 'backup controlfile to trace' command above.

6.Recover database

SQL>recover database ;

7.Open the database

SQL>Alter database open
