Oracle RMAN 10g中如何提高copy datafile的并发

try something like this:

format后面修改为你复制的目标文件名

run

{ allocate channel mac01 DEVICE TYPE DISK MAXOPENFILES=1 PARMS='BLKSIZE=1048576' ;

allocate channel mac02 DEVICE TYPE DISK MAXOPENFILES=1 PARMS='BLKSIZE=1048576' ;

allocate channel mac03 DEVICE TYPE DISK MAXOPENFILES=1 PARMS='BLKSIZE=1048576' ;

allocate channel mac04 DEVICE TYPE DISK MAXOPENFILES=1 PARMS='BLKSIZE=1048576' ;

backup as copy (datafile '+DATADG/MAC/DATAFILE/system.258.819691771' format '/s01/backup/system.dbf' channel mac01)

(datafile '+DATADG/MAC/DATAFILE/sysaux.257.819691725' format '/s01/backup/sysaux.dbf' channel mac02)

(datafile '+DATADG/MAC/DATAFILE/undotbs1.260.819691817' format '/s01/backup/undotbs1.dbf' channel mac03);

}
