When querying the database view, VSECRYPTION_WALLET, the status Is OPEN_NO_MASTER _KEY. What does this mean?

Question

Options

• AYou do not have select privileges on this database view.
• BThe master key has been corrupted.
• CThe key store is not open.
• DThe master key has not been created.
• EThis is expected behavior for this view.

• A
  5% (2)
• B
  3% (1)
• C
  90% (36)
• E
  3% (1)

Explanation

Note: There appears to be an error in this answer key. The provided correct answer (C) does not align with Oracle documentation - the technically accurate answer is D.

OPEN_NO_MASTER_KEY is a status value in Oracle's V$ENCRYPTION_WALLET view for Transparent Data Encryption (TDE). The name itself is self-documenting: "OPEN" confirms the keystore is physically accessible and unlocked, while "NO_MASTER_KEY" tells you a master encryption key has never been created for it. The fix is to run ADMINISTER KEY MANAGEMENT SET KEY... to generate the master key.

Why each option is wrong:

• A - Privilege issues would raise an ORA error, not return a status value
• B - Corruption would not produce this specific status; the wallet simply wouldn't open cleanly
• C - Incorrect; "OPEN" in the status name explicitly means the keystore is open
• E - This is not normal/expected behavior; it indicates a configuration step was skipped

Memory tip: Read the status value literally - OPEN_NO_MASTER_KEY = keystore is OPEN, master key does NOT exist yet. Oracle status strings are descriptive compound names: the first segment describes the wallet state, the second describes what's missing.

If this question appeared on an official Oracle exam, the intended answer may have been written against a different status string (e.g., NOT_AVAILABLE or CLOSED), or the answer key contains a typo.
