Error ORA-03134: Connections to this server version are no longer supported

  • 772

In a web application I use 2 connections to 2 different Oracle 10g servers, I use Visual Studio 2015 Professional, and I have installed the Oracle ODAC 12 libraries on the development computer, I have said library referenced in the application Oracle.DataAccess.dll.

The thing is that the connection to one of the servers works correctly and when it has to open the connection to another, it will report the error:

 ORA-03134: Connections to this server version are no longer supported

Can you give me any clue as to where the problem is? Apparently both ORACLE servers have the same configuration.

  1. The error message says that you are using different versions of Oracle. reference here

    ORA-03134: Connections to this server version are no longer supported.
Cause: An attempt was made to connect to an Oracle server of older version.
Action: Please refer to documentation for more details.

    To check the database engine version run the query:

    select * from v$version;

    Note the version of the client you are using. If it is old, you will have to upgrade the application or the driver.

    Finally I have made a dblink to the server that does not give me problems and in it I have implemented the materialized views that I needed. everything solved.
