Teman2,

Saya newbie di oracle nih.
Kalau saya ingin connect ke database sebagai sysdba tanpa memasukkan password 
bagaimana caranya yah?
OS nya Windows Server 2003, username saya sudah ditambahkan di group ora_dba. 
Namun hasilnya adlah sebagai berikut:

C:\Documents and Settings\denaa>sqlplus /nolog

SQL*Plus: Release 10.2.0.1.0 - Production on Mon Jan 25 15:32:36 2010

SQL> connect / as sysdba
ERROR:
ORA-12560: TNS:protocol adapter error
