How to enforce sys to enter password while connecting to database through OS
Dear All,
Greetings,
How can I enforce sys to enter password while connecting to database through OS. I want to disable "/ as sysdba" connection. I want to allow sys connectivity through password with oracle user. I tried to achieve this by putting following parameter in sqlnet.ora file and changing ownership of sqlnet.ora to root but after those changes we were not able to start RAC databases crs services were erroring out.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
Any Suggestion how to enforce password for sys so that other services are not effected.
Thanks in advance.
Regards,
Salahuddin.
