Oracle database 16章 数据库恢复 整个数据库的完全恢复 恢复整个数据库 理论试验

1、使用RMAN恢复整个数据库

先 shutdown database，然后连接上RMAN，把数据库startup 到 mount状态，使用 database restore命令直接恢复整个数据库，要在恢复文件的目录下有备份文件。

~/app/oracle/flash_recovery_area> sqlplus / as sysdba

connected to target database (not started)

RMAN> startup mount;

2、recover database

RMAN> restore database;

Starting restore at 07-APR-13
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=2186 device type=DISK

channel ORA_DISK_1: starting datafile backup set restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set
channel ORA_DISK_1: restoring datafile 00001 to /home/oracle/app/oracle/oradata/test/system01.dbf
channel ORA_DISK_1: restoring datafile 00002 to /home/oracle/app/oracle/oradata/test/sysaux01.dbf
channel ORA_DISK_1: restoring datafile 00003 to /home/oracle/app/oracle/oradata/test/undotbs01.dbf

3、最后打开数据库

media recovery complete, elapsed time: 00:01:16
Finished recover at 07-APR-13

RMAN> alter database open ;

database opened

RMAN>
