A database is configured in ARCHIVELOG mode. A full RMAN backup exists but no control file backup to trace has been taken. A media failure has occurred. In which two scenarios is incomplete recovery required? (Choose two.). after losing a SYSAUX tablespace data file. after losing all members of an INACTIVE online redo log group. after losing all members of the CURRENT online redo log group. after losing all copies of the control file. after losing an UNDO tablespace that is in use.

Which two are true about instance recovery? (Choose two.). It is not possible if an archived log is missing. It is performed automatically after the database is opened; however, blocks requiring recovery are not available until they are recovered. Setting FAST_START_MTTR_TARGET to a lower value reduces instance recovery time by causing dirty buffers to be written to disk more frequently, thereby reducing the number of I/Os needed during instance recovery. It is performed by the Recovery Writer (RVWR) background process. Setting FAST_START_MTTR_TARGET to a higher value reduces instance recovery time by causing the log writer to write more frequently, thereby reducing the number of I/Os needed during instance recovery. It is performed automatically while the database remains in MOUNT state. Then the database is opened.

SMON rolls back any dead transactions, and then the database is opened. Recovery begins from the last checkpoint position that was recorded in the control file by the checkpoint process (CKPT). Recovery reads redo until the end of the redo thread, and then opens the database. SMON then rolls back any dead transactions.
