Exercise scoring
This is an auto-scored exercise. You will receive 10 points for completing it.
Background/overview
You know that it is important to maintain current backups of your database control files. You also know that those backups should reflect the most recent structural changes to your database. You have just finished adding data files to a tablespace to make room for a fast-growing table. You now want to back up the control file to cover yourself in case a massive drive failure causes you to lose all the online control files.
Instructions
Connect to your database as the
SYSTEM
user, or as any other user having the
ALTER DATABASE
system privilege, and back up your control file to trace.
Hints
The command to use is:
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
Do not forget that like any other SQL statement, you must end this command with a semicolon.
