Judging by the name, look like a medical app. I thinapp-ed plenty of medical apps installing an oracle client but not a database.
First thing you can do is testing the oracle connectivity inside the virtual bubble. Open the package.ini file from your project folder and remove or comment the line "Disabled=1" for the entry point [cmd.exe]. This entry point should be at the end of the file. Then recompile by executing build.bat.
Open the virtual cmd.exe and do the following:
Type tnsping <service name> (for Oracle 7.3 or Oracle 8i and later) or tnsping80 <service name> (for Oracle 8.0), and then press enter.
You can also try to connect with the sql plus command line.
