Question
What state must an Oracle database be in to perform a successful backup? (Select all that apply.)
- OPEN
- ONLINE
- UNMOUNTED
- MOUNTED
Solution
To perform a successful backup of an Oracle database, the state of the database must be managed carefully. The valid options from the provided choices are:
-
OPEN: The database must be in the OPEN state to perform a complete backup. In this state, the database is active, and all data is accessible.
-
ONLINE: When the database is in ONLINE mode, it is also ready for backups. This state indicates that the database is fully operational and responsive.
The other two options:
-
UNMOUNTED: The database cannot be backed up in this state, as it is not accessible at all.
-
MOUNTED: The database must be opened to take a backup, so being in the MOUNTED state alone is not sufficient.
Final Answer
The states that allow for a successful backup of an Oracle database are OPEN and ONLINE.
