12c Se ORA-01017

wilson.moreiraJul 14 2017 — edited Aug 21 2017

After I installed Oracle SE 12c on my server, some clients with 11Gr2 or 9i (OCI,Oledb,.net and ODBC drivers) started to show the following error:

ORA-01017: invalid username/password; logon denied

I've searched for solutions and added to sqlora.net the parameters:

SQLNET.ALLOWED_LOGON_VERSION_CLIENT=9

SQLNET.ALLOWED_LOGON_VERSION_SERVER=9

SQLNET_ALLOWED_LOGON_VERSION = (8,9,10,11)

But still no dice. Is it something I'm doing wrong? Can anyone suggest anything?
