WINBIO_E_DATABASE_LOCKED
WINBIO_E_DATABASE_LOCKED means the selected biometric database is locked. The lock may be a valid exclusive operation, a stale session, or an underlying storage-adapter synchronization issue.
What to check
- Identify active enrollment, maintenance, or administration operations that can hold an exclusive lock.
- Close abandoned sessions cleanly and avoid concurrent database maintenance from multiple clients.
- If the lock persists after all clients have ended, inspect the vendor storage adapter and service logs.
