Oracle uses SYS login times wrong ORA-28009 solution

situation one: log in using Sqlplus:

Enter the password of the user name normally, will be error, because SYS is a super administrator outside the database, so when we log in

to enter a password: password +as sysdba (for example: 123456 as SYSDBA)

Scenario Two: log on with PL/SQL :

This is the normal operation of our normal login database, but with SYS is logged in as a user name and is reported

Ora-28009:connection as SYS should be as SYSDBA OR sysoper such an error

The workaround is to:

You can log on successfully by changing the normal connection as option box to SYSDBA or Sysoper.
