Oracle connector supports connection to Oracle 11/12 and above (Oracle 11gR1, 11gR2, 12c) version(s) and the above error indicates that the Oracle database version is older then the supported one. To verify the Oracle database version, run the following command in an Oracle client.

SELECT * FROM V$VERSION

To resolve this issue, request your DBA to upgrade Oracle database to a supported version.Till the time database version gets updated, you can connect to an existing Oracle database by making use of Information Designer (information link). https://docs.tibco.com/pub/spotfire/general/sr/GUID-0E4DC24F-8D6A-4C1B-8544-5DE9D503B76E.html
