After upgrading DB to 12.1 connections fail with ORA-28040

This is just a discussion (reference information) regarding the ORA-28040 error happening after a Database upgrade which has resulted in quite a few SRs opened.

This seems to be caused by one of the following (references following):

1. The Client connecting is not at a version high enough to be certified to connect to the Database version (Interoperability issue).

2. The Client connecting is not running an Authentication Protocol version permitted by the Database settings (Authentication Protocol issue).

3. The JDBC Thin Client is not at a level or does not support or does meet the Authentication requirements set by the 12.1 Database (JDBC Thin issue).

Howdy, Stranger!
