    Oracle 9c connection

    Hi,

    I am trying to create a Winforms app, connecting to an Oracle 9c server.

    When using a reference to Oracle.DataAccess.dll, I receive the following error when I try to open the connection.

    'Oracle.DataAccess.Client.OracleException: 'ORA-03134: Connections to this server version are no longer supported.'

    I understand what the error is telling me, what I need is a work around.

    Any ideas?

    Thanks,

    --Bob H

    Pretty simple. Use an older version of the DLL (max would be 11 as they only support back 2 major versions), upgrade the db version to within 2 major versions (or use an intermediary database that is within 2 versions) or don't use the Oracle data provider to make your connection.

    Hi,

    This is just what I ended up doing.

    I pointed to the 11g client (Oracle.DataAccess.dll), and everything got better!

    I just wish the company would just hurry up and update to 12. Unfortunately, a bunch of old legacy Power Builder apps connect to the 9c server.

    Thanks for the hand
