模拟数据库奔溃，删除控制文件，这是数据库还在继续运行，可能要过一会切换日志才奔溃。这里我直接重启一下数据库

[oracle@oracle dbs]$ cd /u01/app/oracle/oradata/ORCL/controlfile/

[oracle@oracle ORCL]$ cd [oracle@oracle controlfile]$ ls

o1_mf_8f860sx8_.ctl

[oracle@oracle controlfile]$ mv o1_mf_8f860sx8_.ctl o1_mf_8f860sx8_.ctl.bak

[oracle@oracle controlfile]$ ls

o1_mf_8f860sx8_.ctl.bak

[oracle@oracle controlfile]$ sqlplus / as sysdba

SQL> startup force

ORACLE instance started.

Database Buffers 159383552 bytes

Redo Buffers 3878912 bytes

ORA-00205: error in identifying control file, check alert log for more info---------------提示查看告警信息了，无法启动！

3、恢复数据库

设置一下oracle_sid，进入rman，启动一个伪实例到nomount状态，因为数据库已经奔溃了，可以通过echo $ORACLE_SID查看原来的SID。这里是假设原来$ORACLE_SID没设置

[oracle@oracle dbs]$ export ORACLE_SID=test

[oracle@oracle dbs]$ echo $ORACLE_SID

test

[oracle@oracle dbs]$ rman target/

Recovery Manager: Release 11.2.0.1.0 - Production on Thu Feb 21 20:25:07 2013

connected to target database (not started)

查看备份集的位置，第一步备份后有查看。先启动到nomount状态，恢复spfile参数文件：

RMAN> startup nomount

startup failed: ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/db_1/dbs/initttt.ora'----------------产生了一个文本格式参数文件

channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete

Finished restore at 21-FEB-13

参数文件恢复完成，此时，在DBS目录下有一个以当前oracle_sid.ora为后缀的参数文件：

[oracle@oracle dbs]$ ll spfilettt.ora

-rw-r----- 1 oracle oinstall 4608 Feb 21 22:21 spfilettt.ora

这时候可以通过参数文件知道原来，数据库的ORACLE_SID,一般情况下和db_name一样，这样就可以还原原来的参数文件名

停掉伪实例，还原原来的参数文件名，我这里原来是orcl

RMAN> shutdown immediate

[oracle@oracle dbs]$ mv spfilettt.ora spfileorcl.ora

因为知道了原来的SID，要重新设置SID变量再进行恢复

[oracle@oracle dbs]$ export ORACLE_SID=orcl

[oracle@oracle dbs]$ rman target/

Recovery Manager: Release 11.2.0.1.0 - Production on Thu Feb 21 21:30:29 2013

RMAN> startup nomount

恢复控制文件，备份集位置不在重复查看了

RMAN> restore controlfile from '/u01/app/oracle/flash_recovery_area/ORCL/backupset/2013_02_21/o1_mf_ncsnf_TAG20130221T201442_8ld419dj_.bkp';

因为除了恢复备份的日志之外，还要恢复备份后产生事务的日志，从错误提示可以看出已经应用到o1_mf_3_8f8616pf_.log

这时候去归档日志目录查看一下

[oracle@oracle dbs]$ cd /u01/app/oracle/flash_recovery_area/ORCL/onlinelog/

[oracle@oracle onlinelog]$ ll

total 153612

-rw-r-----. 1 oracle oinstall 52429312 Feb 21 21:26 o1_mf_1_8f860yp8_.log

-rw-r-----. 1 oracle oinstall 52429312 Feb 21 21:26 o1_mf_3_8f8616pf_.log

应用到最后一份归档了下一份就是 current redo. 如果没有的话直接resetlogs启库这样就是不完全恢复

RMAN> alter database open resetlogs;

database opened

数据库正常启动

我们来查看一下数据是否和数据库崩溃之前一样

[oracle@oracle onlinelog]$ sqlplus / as sysdba
