Answer 1

you cannot log into database with "SYS" user without specifying the sysdba privileges . SYS is default users, created with the creation of the database. Although they have much power - as they are granted the DBA role - they're still ordinary users. Because SYS owns the data dictionary, (s)he is considered a bit more special .
Here you can unlock the sys account as
