This document describes how to connect to an Oracle instance that uses Enterprise User Security (EUS).


When trying to connect to an Oracle instance that uses EUS see the following error message will be shown when trying to create a JDBC data source in Virtual DataPort: "unsupported verifier type".

In order to avoid this issue, the following steps can be followed:

  • Open the Denodo Control Center.
  • Click on Configure.
  • Click on JVM Options.
  • Add the text -Doracle.jdbc.thinLogonCapability=o3 at the end of the text for the Virtual DataPort Server / ITPilot Wrapper Server configuration. For instance:




  • Click Ok.
  • Save the changes and restart the Virtual DataPort server.

Once this option is added to the JVM configuration it will be possible to create a JDBC data source in Virtual DataPort against an Oracle instance with EUS.
