ORA-01017 error arfter 8.1.7 install
I installed Oracle 8.1.7 and then committed the SQL*Net authentication
services in SQLNet.ora file. Now if I connect with internal user and
Oracle password to explicitly close the database it gives ORA-01017:
Invalid username/password; login denied. When I remove the comments
from SQLNet.ora, it works.
I'm not sure you're commenting the file properly then because comments
shouldn't cause any issues. The proper comment character in the sqlnet.ora is
the pound sign (#).
If you think you're doing things right, maybe a non-printable character found its way into your sqlnet.ora file to cause your issue. In that case, I'd open a new text editor and retype the contents of the file by hand, then save it over the top of your existing file.
