With the Partitioning option
SQL> select username, account_status from dba_users where username like 'SYS%';
USERNAME ACCOUNT_STATUS
------------------------------ --------------------------------
SYSTEM LOCKED
SYS LOCKED
1. How can I log in to SYS account despite being locked. Is it because i logged in through external authentication?
2. Is locking the SYS user a standard practise ? If so, why ?
