Editor to share with you what are the problems encountered in disabling sysdba remote login in oracle, I believe most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.

For the sake of security, sometimes you need to disable sysdba remote login. You can log in locally and search the information on the Internet as follows:

Alter system set remote_login_passwordfile=none scope=spfile sid='*';-needs to restart the database

Vi $ORACLE_HOME/network/admin/sqlnet.ora

# add the following record

SQLNET.AUTHENTICATION_SERVICES= (NTS)

And then lsnrctl reload

But there will be a problem, after the database restart, local login, sys user startup database, prompt no permissions

SQL > startup

ORA-01031: insufficient privileges

Solution:

Remove the SQLNET.AUTHENTICATION_SERVICES= (NTS) record of $ORACLE_HOME/network/admin/sqlnet.ora and lsnrctl reload it.

So to disable sysdba remote login, you can log in locally, and after restarting the database, it does not affect startup, just need

Alter system set remote_login_passwordfile=none scope=spfile sid='*'
