ORA-28040 "No Matching Authentication Protocol" Following an Upgrade to 12c?

edited Apr 20, 2017 12:59PM in Database Networking (MOSC) 1 commentAnswered

The following sqlnet.ora file parameter has been deprecated in Oracle version 12.1.

SQLNET.ALLOWED_LOGON_VERSION=n  Where n is the version of client you'd like to connect.

This parameter has been replaced in version 12c by the following settings:

SQLNET.ALLOWED_LOGON_VERSION_SERVER=n

SQLNET.ALLOWED_LOGON_VERSION_CLIENT=n


Please refer to the following document:

12c: ORA-28040 After Upgrade: No Matching Authentication Protocol (Doc ID 1957995.1)


It's important to note the following:


1)  The default setting for this parameter in 12c is 11 or:


SQLNET.ALLOWED_LOGON_VERSION_SERVER=11

SQLNET.ALLOWED_LOGON_VERSION_CLIENT=11

See the following reference:https://docs.oracle.com/database/121/NETRF/sqlnet.htm#NETRF2010
