when I set the environment and log in as sys, it's wokring fine; however, when I log in the database as SYS and using the connect string, Oracle tells me it's INVALID password.
ON SQl net, I already set:
#NAMES.DEFAULT_DOMAIN = qdev.net
on the init.ora, I have
remote_login_passwordfile=EXCLUSIVE (which is the samething with other instances on the same server, and I was able to log in the isntances instance fine using the connect string)
