We get this question a lot. In most cases, companies may user Oracle Full use licenses in a development environment by downloading Oracle products from the Oracle Technology Network (OTN). Users must agree to the Oracle Technology Network Developer License Terms, which gives licensing rights to the single user to use the application(s) in a development environment only. The OTN Development License also limits the use of the product to only one person and limits installation of the product to one server. In addition, the Oracle products cannot be used for any internal data processing operations or for any commercial or production functions. So, Oracle licensing is pretty clear in a development environment – one person, one server and for development environment only. If you have a multiple user development environment (and most organizations do), then a license is required.
