Hi All

I am trying to grant a user admin sysdba rights. I use the command grant sysdba to admin and get theerror below
ORA-01994: GRANT failed: cannot add users to public password file

I have checked my for the error code ORA-01994 and it says
ORA-01994: GRANT failed: cannot add users to public password file
Cause: A grant failed because a user could not be added to the password file. This is because the value of the REMOTE_LOGIN_PASSWORDFILE initialization parameter is set to PUBLIC.

Action: To add a user to the password file, shutdown the database, change the REMOTE_LOGIN_PASSWORDFILE initialization parameter to PRIVATE, and restart the database.

My question is how do I change the remote_login_passwordfile initialization parameter to PRIVATE

Thanks in advance
