I am new to DB. I am trying to figure this one, but could not. I have a 12c Personal DB.
My SYS password is "a".
But I can to this after shutdown:
SQL> CONNECT sys/kdkd As sysdba
Connected to an idle instance.
SQL> STARTUP
ORACLE instance started.
Total System Global Area 1670221824 bytes
Fixed Size 2403352 bytes
Variable Size 1006633960 bytes
Database Buffers 654311424 bytes
Redo Buffers 6873088 bytes
Database mounted.
Database opened.
SQL>
How can I login as SYS giving wrong password and start the DB? I know there is a password file (I found one in C:\ORACLE_BASE_PE\product\12.1.0\dbhome_1\RDBMS\xml\dbms_passwd.xml.11.1).
But I don't understand what happens here? I am logged in to the machine, as an OS user who belongs to the Windows 7 Administrators group.
Any advice would be greatly appreciated.
