Test with TIBCO Rendezvous gives "Native implementation required" error

Technote (troubleshooting)


When you use a TIBCO Rendezvous (RV) transport in IBM Rational Integration Tester (RIT), you see the error: "Could not create the underlying RV transport - Native implementation required"


When you run a test or you click the Test Transport button in RIT you see the following error.

Could not create the underlying RV transport - Native implementation required.

You have previously used Green Hat Software GH Tester successfully with TIBCO RV, but you see that the function does not work in RIT.


RIT cannot access the TIBCO RV binary library files.

Another possible cause is that your computer has the the 32-bit version of RV installed. RIT is a 64-bit application and will not work with the 32-bit RV.

Diagnosing the problem

Contact your TIBCO administrator to verify which version of Rendezvous you have and whether it is 32-bit or 64-bit.

Resolving the problem

  1. Verify that the 64-bit version of TIBCO RV runs on the same system that RIT is running on.

    Unlike other messaging systems, you need both Java and binary library files to perform RV messaging. It is not sufficient to copy just the Rendezvous client JAR onto the system and configure it in Library Manager.

    You need the 64-bit version of RV, because RIT is a 64-bit application. RIT will not work with the 32-bit version of RV.

  2. See the TIBCO Rendezvous documentation to verify that RV is installed correctly.


    Verify that the system variable PATH includes the Rendezvous bin folder.

    A typical location is


    This should be set automatically when RV is installed.


    Verify that the system variable LD_LIBRARY_PATH or LIBPATH contains the Rendezvous lib folder.

    A typical location is


  4. Verify that the value of java.library.path in RIT includes the folder mentioned in step 3 above.

    Click Help > Configuration Details.

  5. Ensure that the version of RV selected in Library Manager matches the first RV library location specified in the system variables in step 3.

    This applies, if you have multiple versions of RV installed, You cannot mix different versions of JAR and library files.
