RMAN 各种场景恢复

--恢复整个数据库

run {

shutdown immediate;

startup mount;

restore database;

recover database;

alter database open;} 

--恢复表空间users

run {sql 'alter tablespace users offline';

restore tablespace users;

recover tablespace users;

sql 'alter tablespace data online';} 

--恢复数据文件适用所有表空间数据文件

run{

shutdown immediate;

startup mount;

restore datafile '/u01/app/oracle/oradata/data01.dbf';

recover datafile '/u01/app/oracle/oradata/data01.dbf';

alter database open;

} 

非system表空间的数据文件，也可以直接在open状态下restore和recover

run {sql 'alter database datafile 6 offline';

restore datafile 6;

recover datafile 6;

sql 'alter database datafile 6 online';

} 

--临时表空间损坏重新建立一个临时表空间

SQL> create temporary tablespace temp1 tempfile '/u01/app/oracle/oradata/test10g/temp101.dbf' size 200M ;

将建好的TEMP1表空间设置为数据库默认的临时表空间

SQL> alter database default temporary tablespace temp1;

DROP掉旧的TEMP的表空间　

SQL> drop tablespace temp including contents and datafiles; 

--全部控制文件损坏

run {

shutdown immediate;

startup nomount;

set dbid=1187100180;

restore controlfile from '/u01/backup/20131202_TEST11G_64.bak';

alter database mount;

recover database;

alter database open resetlogs;

}

打开后对数据库做一次全备份  --spfile损坏

run {

shutdown immediate;

startup nomount;

set dbid=1176041295;

restore spfile from '/u01/backup/20131202_TEST11G_64.bak';

shutdown immediate;

startup;
