I am in the same situation.
I need to script Oracle Demantra in Vugen but cannot find a way to record the interactions at the form level.
Usually for oracle I go Web+OracleNCA but the interactions with the forms are not recorded like this.
Vugen protocol analyzer suggests to use Java over http but it also does not record the forms part.
Is there anyone successful with using LoadRunner 11.52 for Oracle Demantra performance testing? I contacted HP support but they said it is not supported.
