You have a readonly tablespace on readonly media. You want to perform a media recovery on the existing data files, but using a backup control file. The backup control file indicates that the status of the readonly tablespace was read/write when the control file was backed up. What should you consider?()
- Adrop the readonly tablespace and recreate the tablespace after recovery
- Btake data files from the readonly tablespace offline before performing a recovery
- Cperform a recovery; status of the tablespace in control file will be changed automatically
- Drecovery using backup control file is not possible, so restore all the files from the last full database backup, and then open the database
