663.Which options would you consider while configuring a flash recovery area (fast recovery area in 11gRelease 2) for your production database that is running in ARCHIVELOG mode? (Choose all that apply.)
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
Answer: CD
闪回恢复区FRA由以下二个参数控制：
DB_RECOVERY_FILE_DEST_SIZE：FRA的大小；
DB_RECOVERY_FILE_DEST：FRA的位置。
在RAC环境下，这二个参数必须在所有实例中保持一致。
启用FRA，就不能启用LOG_ARCHIVE_DEST和LOG_ARCHIVE_DUPLEX_DEST参数。
