I was triggered by the article of Uma Prabhala on Steven Chan's weblog, called Ten Ways of Using iSetup to Streamline E-Business Suite Implementations. To be honest, I thought that iSetup was decommisioned (see the message on https://isetup.oracle.com), but it appears that it is still alive and in fact it looks more promising then ever. When I tried to do the setup I encountered an issue on creating a .dbc file, which is a mandatory setup step.
