Oracle Data Provider for .NET FAQ


  Q: I bundle ODP.NET with an application I've built, which I want to distribute or sell. Does Oracle charge licensing fees for this?
  
  A: In most cases, Oracle does not charge any fees for distributing the
  Oracle client nor ODP.NET with a third-party application. However, it
  is best to consult the licensing agreement from which you acquired
  rights to the Oracle software. If you purchased Oracle licenses
  directly from Oracle, consult your Oracle licensing contract or your
  Oracle sales representative. If you downloaded ODP.NET from OTN,
  consult the licensing agreement that you agreed to prior to
  downloading the software.
