考题 In your database, you discovered that a tempfile in a locally managed temporary tablespace has been deleted at the operating system level. How would you recover the tablespace?()A、flash back the databaseB、perform point-in-time recoveryC、perform a full database recoveryD、drop and re-create the tablespaceE、use Recovery Manager (RMAN) to recover the database

考题 Because of a logical corruption in your production database, you wanted to perform Tablespace Point in Time Recovery (TSPITR). But before you start the recovery, you queried the TS_PITR_OBJECTS_TO_BE_DROPPED view and realized that there are a large number of objects that would be dropped when you start the recovery by using this method. You want to preserve these objects. Which option must you use to perform TSPITR and preserve the object?()A、Perform Export before TSPITR and Import after TSPITRB、Move objects to another schema that has the same tablespace assignedC、Perform Incomplete Recovery before TSPITR with the Log Sequence Number (LSN)D、Perform Incomplete Recovery before TSPITR with the System Change Number (SCN)
