Oracle Study之案例--重建数据库控制文件

系统环境：

操作系统： Linux RH6

数据库：   Oracle 11gR2

   案例分析：

          数据库中所有的控制文件被意外破坏，非归档的库，在有trace备份的情况下，重建控制文件。

1、控制文件trace脚本

[oracle@rh6 ~]$ cat crctr.sql 
CREATE CONTROLFILE REUSE DATABASE "TEST3" NORESETLOGS  NOARCHIVELOG
    MAXLOGFILES 10
    MAXLOGMEMBERS 5
    MAXDATAFILES 300
    MAXINSTANCES 1
    MAXLOGHISTORY 292
LOGFILE
  GROUP 1 '/u01/app/oracle/oradata/test3/redo01a.log'  SIZE 100M BLOCKSIZE 512,
  GROUP 2 '/u01/app/oracle/oradata/test3/redo02a.log'  SIZE 100M BLOCKSIZE 512
-- STANDBY LOGFILE
DATAFILE
  '/u01/app/oracle/oradata/test3/system01.dbf',
  '/u01/app/oracle/oradata/test3/sysaux01.dbf',
  '/u01/app/oracle/oradata/test3/undotbs01.dbf',
  '/u01/app/oracle/oradata/test3/users01.dbf'
CHARACTER SET ZHS16GBK；
로그인 후 복사

2、启动Instance到nomount，重建controlfile

10:59:05 SYS@ test3 >startup nomount;
ORACLE instance started.

10:59:41 SYS@ test3 >@/home/oracle/crctr.sql
Control file created.
로그인 후 복사

3、告警日志

3、查看数据库状态

11:00:03 SYS@ test3 >select status from v$instance;

11:00:27 SYS@ test3 >select file#,name ,checkpoint_change# from v$datafile;

4、打开数据库

11:00:54 SYS@ test3 >alter database open;
alter database open
*
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/u01/app/oracle/oradata/test3/system01.dbf'

---打开数据库报错，需要做“media recovery”

执行介质恢复：
由于本库为非归档模式，只能通过current redolog来恢复

*********************************************************************
WARNING: The following temporary tablespaces contain no files.
         This condition can occur when a backup controlfile has
         been restored.  It may be necessary to add files to these
         tablespaces.  That can be done using the SQL statement:
 
         ALTER TABLESPACE <tablespace_name> ADD TEMPFILE
 
         Alternatively, if these temporary tablespaces are no longer
         needed, then they can be dropped.
