第13题:
Media recovery can sometimes be stopped by the inability to read past a certain point in the redo stream. This is often referred to as “stuck recovery”. Before Oracle9i, the Database Administrator had few options to deal with stuck recovery. If the corrupt redo could not be recovered from some other source, then all transactions that committed after the corrupt point in the redo steam would be lost. Oracle9i changes that with the Trial Recovery feature. Trial Recover is used to test the application of the redo logs to the database. What are three other characteristics of Trial Recovery()

第19题:
Rebuild the index using the online option.
Take the individual data file offline (not the whole tablespace), restore and recover the data file from backup with RMAN, then set the data file online again.
Without setting the individual data file offline, use RMAN with Block Media Recovery to restore and recover only those blocks.
Take the individual data file (not the whole tablespace) offline, use RMAN with Block Media Recovery to restore and recover only those blocks, then set the data file online again.

第23题:
You need to perform the restore and recover operations manually, because the backup was made manually.
First you need to resynchronize the catalog with the control file, and then you can use RMAN to recover the database.
First you need to add the backup to the catalog using the CATALOG command, and then you can use RMAN to recover the database.
You can just use RMAN and recover the database, because RMAN automatically updates the catalog with the backup information.
