Oracle Database Discussions

I wondered OS authentication for SYSDBA users disabled automatically if I STARTUP the database by login as SYSDBA through PASSWORDFILE authentication.



For example:-



$ sqlplus



sys@orcl as sysdba

password:-



SQL>STARTUP

After starting database if you try to login as SYSDBA through OS authentication you can't.



$ sqlplus "/as sysdba"



SQL> CONNECTED TO IDLE INSTANCE (Even your database is running).



If anyone already faced this issues and have some solutions, please tell me
