Crystal Report fails to export after moving to Oracle 10

Moved database from Oracle 9 to 10 Recently.  Report was fine before the move. The process is .net, it retrieves documents to process into a table.  Then each record is processed.  Crystal is called to create a pdf and export it to a local drive.  The application server has not been modified.  Here is the error:

 CrystalDecisions.ReportAppServer.DataSetConversion CrystalDecisions.CrystalReports.Engine.DataSourceException: Database Connector Error: ' [Database Vendor Code: 22835 ]'
Failed to retrieve data from the database.
Failed to export the report.

When you changed databases did you update the reports to use the new connections and database drivers?

Can you open a report in the designer and do a VERIFY DATABASE?

What version of Crystal?

Did you write the application or is it a commercial/vendor product?

According to Oracle this error Is

Buffer too small for CLOB to CHAR or BLOB to RAW !!!

Do you have this kind of data on the report ? You may need to update also your .NET drivers
