I don't want to change the current profile for my default connection since my web application basically connects to MySQL it happens that some of the data is stored in oracle, so I've created another database connection profile ... by default the web application is running under MySQL... I just want to connect to oracle when needed... or if possible simultaneous connection between MySQL and Oracle.
