第20题:
RMAN will attempt to make the backup run as fast as possible without any IO limitations.
RMAN will automatically restrict the number of channels in use to one.
RMAN will spread the backup IO over the total duration stated in the backup command.
RMAN will skip any datafile that currently is involved in an IO operation. RMAN will retry backing up the datafile later and an error will be raised at the end of the backup if the datafile cannot be backed up.
Datafiles will be backed up; those having the lowest current number of IO operations will be backed up first.
第21题:
Datafiles
Current control file
Server parameter file (spfile)
Password file
第22题:
A different procedure is required to restore a database from compressed backups
The AS COMPRESSED clause of the BACKUP command provided by RMAN is used to create compressed backup sets and image copies.
Using this command to create backups minimizes the bandwidth consumed
Using this command to create backups improves the performance of the backup process
