Question about DB not visible in SRVCTL STATUS DATABASE -D prod

Hi,

srvctl status database -d prod as below

Instance prod1 is not running on node server1

Instance prod2 is not running on node server2.

However, I see the database running from sqlplus as below

SQL>select name,open_mode from v$database;

NAME                          OPEN_MODE

-------------                   ----------------------

PROD                                 READ WRITE

Scan listener and local listener are running  on both ndoes.

My question

1. My database is  production &  I can't shutdown the db from SQLPLUS. Is there a way to register the db with 'srvctl status' command without shutting down the db and starting from srvctl?

2. Will the users be able to access  both the  db instances? Will there be a performance issue?
