表的许多分区被意外drop用rman不完全恢复

export ORACLE_SID=xxx
sqlplus / as sysdba
startup nomount pfile='/home/oracle/init_xxx.ora';
create spfile from pfile='/home/oracle/init_xxx.ora';

exit

RMAN target sys/xxx
restore controlfile from '...';
startup mount
--crosscheck backup;
list backup;

run 
{
set newname for datafile 1 to '/oracle/oradata/xxx/system01.dbf';
set newname for datafile 2 to '/oracle/oradata/xxx/undo01.dbf';
set newname for datafile 3 to '/oracle/oradata/xxx/sysaux01.dbf';
set newname for datafile 6 to '/oracle/oradata/xxx/pay_ts01.dbf';
restore datafile 1;
restore datafile 2;
restore datafile 3; 
restore datafile 6;
}
(注：发现单个datafile恢复不如整库恢复快！)
sql 'alter database backup controlfile to trace';
shutdown immediate;
exit
