I recently recovered a database from backup onto a new Linux server to test DR, but I am not being able to register it with the listener, it shows status as "UNKNOWN" instead of "READY". Here is some more info:

UNKNOWN is the expected behaviour if the database is not open.

But my instance status is "OPEN"?

SQL> select status from v$instance;

STATUS
------------
OPEN

This is wrong,
LISTENER_GBM12P =
(ADDRESS = (PROTOCOL = TCP)(HOST = TMP-HQ-LDORA1)(PORT = 1521)
You are missing the closing )

Sorry, that was a copy-paste error, I had missed the last bracket when copying. However, I bounced the database, and the listener now shows a "READY" instance for it.

I had done a few "alter system register", but that had not registered the instance. Weird.

Thank you very much for your advice.
