You regularly take backups of your database using RMAN with a recovery catalog. Your database is currently open and the temp01.dbftemp file belonging to the TEMPtablespace is corrupted. Identify two methods to recover the temp file with the least disruption to database availability.
Correct Answer: B,C
Explanation/Reference: Explanation: Temp files are a special class of data files that are associated only with temporary tablespaces. B: After restore and recovery of a whole database, when the database is open, missing temporary tablespaces that were recorded in the control file are re-created with their previous creation size, AUTOEXTEND, and MAXSIZE attributes. Only temporary tablespaces that are missing are re-created. If a temp file exists at the location recorded in the RMAN repository but has an invalid header, then RMAN does not re-create the temp file. If the temp files were created as Oracle-managed files, then they are re-created in the current DB_CREATE_FILE_DEST location. Otherwise, they are re-created at their previous locations. C: If a data file becomes missing or corrupted. You must take it offline before you can open the database.
