3．进入rman中恢复控制文件。 RMAN> run { 2> allocate channel ch00 type sbt_tape; 3> SEND 'NB_ORA_SERV=master,NB_ORA_CLIENT=client'; 4> restore controlfile to '/tmp/control.bak' from ' /cntrl_47_1_960598675'; 5> release channel ch00; 6> }

run { replicate controlfile from '/tmp/control.bak'; }

4.mount数据库. sql> alter database mount; Database altered.

5恢复数据文件 RMAN> run { 2> allocate channel ch00 type sbt_tape; 3> SEND 'NB_ORA_SERV=master,NB_ORA_CLIENT=client'; 4> set until time "to_date('2012-08-09:00:00:00','YYYY-MM-DD:HH24:MI:SS')"; 5> restore database; 6> release channel ch00; 7> }

6.启动oracle数据库。 Alter database open resetlog;
