ora-28040 no matching authentication protocol 12c

[Boosa]

Hello,

when I try to connect to our new Oracle 12c Database with C# in DirectMode, I get the error ORA-28040. (No problems with 11g R2)
I'm pretty sure the reason is that we use an old Version of dotConnect. It's the Version 5.70.
Can anyone confirm my assumption?

Thank you...

You are right, Oracle 12c is supported since dotConnect for Oracle 8.0.17 and can't be used with dotConnect for Oracle 5.70. For more information, please refer to http://www.devart.com/dotconnect/oracle ... story.html

dotConnect for Oracle has a Trial version which allows you to evaluate dotConnect for Oracle during 30 days since the provider installation. You can download the Trial version of dotConnect for Oracle from our site http://www.devart.com/dotconnect/oracle/download.html

Thank you,
instead of upgrading our dotConnect for Oracle we think about purchasing a license for the dotConnect Universal.
We want to use this for Oracle, MSSQL, MySQL and DB2.
We purchased dotConnect Oracle only for the directmode connection to Oracle without installing the client on all workstations. We don't use any specific tools like Entity Framework etc...
Is it possible with dotConnect Universal to connect to Oracle and DB2 in directmode without installing the particular client software?
I read some docs on this page but didn't found a clear answer.

dotConnect Universal Professional Edition supports the runtime functionality of the Standard Edition of dotConnect for Oracle, dotConnect for MySQL, dotConnect for SQLite, and dotConnect for PostgreSQL and allows using general ADO.NET functionality only. Standard edition of dotConnect for Oracle supports Direct Mode, and you can establish connections to Oracle server with dotConnect Universal without Oracle Client. For more information, please refer to

dotConnect Universal has a set of supported providers that you can use without additional settings. For DB2, IBM DB2.NET Data Provider is supported. For more information, please refer to http://www.devart.com/dotconnect/univer ... iders.html

However, unlike dotConnect for Oracle, IBM DB2.NET Data Provider is not supplied with dotConnect Universal. You need to install IBM DB2.NET Data Provider on the computer where your application is used in order for dotConnect Universal to be able to work with DB2 database.
