You work as a database administrator for Certkiller .com. You added atablespaceto your database. Because of the changes to the physical structure of your database, you performed a backup of the control file to trace. After this, you lost only the control files and the instance aborted due to a hardware failure.  How would you proceed to recover the database?()

  • A、Start the instance and open the database, instance recovery automatically recovers control files 
  • B、Create a file based on the contents of the trace file and save it to the control file locations and start the database 
  • C、Re-create the database (The recovery of the control file is not possible because you have lost all the control files.) 
  • D、Start the instance, in the NOMOUNTstate,re-create the control file using the CREATE CONTROLFILE command stored in the trace file. 
  • E、Start the instance and MOUNT the database, then re-create the control file using the CREATE CONTROLFILE command stored in the trace file.
