C. An overflow tablespace must have been specified.
D. The PCTTHRESHOLD option must have been specified.
Q32. Examine the following set of RMAN commands:
RMAN> CONFIGURE CHANNELdelDEVICETYPEDISK FORMAT '/u02/backup/%U*;
Which statement is true when the RMAN run block is executed?
A. The execution of the script fails because multiple channels cannot coexist.
B. The script is executed and both the channels are used for the script execution.
C. The new channel, CH1, is ignored because a channel has been configured already.
D. The persistent configuration parameter DC1 is overridden because a new channel is allocated in the RMAN run block.
Q33. Identify two correct statements about the Active Session History (ASH) data.
A. A part of SGA memory is used to store ASH data as rolling buffer.
B. The ASH data can be analyzed between any two small time intervals.
C. All ASH data in memory are flushed to disk by MMON in every 3 seconds.
D. All ASH data in memory are flushed to disk by MMNL process whenever the buffer is full.
Q34. In your database, the flash recovery area (FRA) is configured as the default for RMAN backups. You executed the following commands to configure the settings in RMAN: Which statement is true about the outcome?
A. Only one channel is allocated and the backup is created in the flash recovery area
B. Only one channel is allocated and the backup is created in the destination specified for channel
C. Two channels are allocated and backup sets are created in the destinations specified for channels 1 and 2
D. Three channels are allocated and backup sets are created in the destinations specified for channels 1, 2, and FRA

A. setting the FAST_START_MTTR_TARGET to set the mean time to recover
B. setting the RECOVERY_PARALLELISM parameter to twice the number of CPUs
C. using the DB_RECOVERY_FILE_DEST parameter to set the location for flash recovery area
D. using the DB_RECOVERY_FILE_DEST_SIZE parameter to define the disk space limit for the recovery files created in the flash recovery area.
