Read-only datafiles will not be backed up as long as backups of those files already exist and those backups meet established retention criteria.
RMAN will configure itself for maximum performance at the cost of CPU.
RMAN will configure itself for minimal OS/CPU impact at the cost of time to back up the database.
RMAN will automatically compress backups.
第1题:
Your PROD database has been started using the server parameter file. In your PROD database you are using RMAN for backup and recovery operations. You issue the following commands from the RMAN prompt: RMAN> CONFIGURE CONTROLFILE AUTOBACKUP OFF; RMAN> BACKUP DATABASE; Which files from the database will be backed up as a result of this BACKUP command?()
第2题:
You have enabled backup optimization in RMAN. You issue the following RMAN command to configure a redundancy-based retention policy: CONFIGURE RETENTION POLICY TO REDUNDANCY 3; Which statement is true?()
第3题:
You set the recovery window to seven days and the backup optimization to ON using the CONFIGURE command of Recovery Manager (RMAN). The most recent backup of the TOOLS tablespace to disk was taken on January 3. The TOOLS tablespace is read/x7fonly. On February 21, when you execute a command to back up all the tablespaces to disk, you find that RMAN backs up the TOOLS tablespace also, even though the contents of the tablespace have not changed after the backup on January 3. Because there are no changes made to the TOOLS tablespace, you decide that the tablespace should not be backed up by RMAN. What can you to do skip backing up the TOOLS tablespace without changing the current backup optimization setting?()
第4题:
You issued the following RMAN command: RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON; What is NOT an impact of using the above command?()
第5题:
Your database is running in the ARCHIVELOG mode. You have configured RMAN for backup and recovery operations. You execute the following command from the RMAN prompt: RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON; After executing this command, in which of the following cases will RMAN make an auto-backup of the control file? ()
第6题:
Consider the following scenario for your database: - Backup optimization is enabled in RMAN. - The recovery window is set to 7 days in RMAN. - The most recent backup to disk for the TOOLS tablespace was taken on November 3, 2007. - The TOOLS tablespace is read-only since November 4, 2007. On November 23, 2007, you issue the RMAN command to back up the database to disk. Which statement is true regarding the backup of the TOOLS tablespace?()
第7题:
You defined the Recovery Manager (RMAN) retention policy to recovery window of 7 days by executing the following command: RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS; When a backup is performed, what would be the status of this backup after seven days?()
第8题:
In which scenario, will you issue the following command?() RMAN> REPORT NEED BACKUP DAYS 7;
第9题:

第10题:
You configured the default backup device type as disk for RMAN backups. In your database,because of business requirements,you have to take a simultaneous duplicate backup of the data files when the RMAN BACKUP command is used. What must you set using the RMAN CONFIGURE command to achieve this?()
