Question 3
Your database is open and the listener LISTENER is up. You issue the command:
LSNRCTL> RELOAD
What is the effect of reload on sessions that were originally established by listener?
- Only sessions based on static listener registrations are disconnected.
- Existing connections are not disconnected; however, they cannot perform any operations until the listener completes the re-registration of the database instance and service handlers.
- The sessions are not affected and continue to function normally.
- All the sessions are terminated and active transactions are rolled back.
Correct answer: C
