There’s no technical difference between an embedded version of an Oracle license and a full use version of an Oracle license. It’s essentially the same product. The only difference is the licensing definition and rules that pertain to each. When you purchase an Oracle license, you do not own the license; you just simply own the right to use the software in a very specific way. When you have an embedded license versus a full use license, it’s the same software. Essentially, the only the difference is what you have rights to do with that software which could be radically different. With an embedded license, you’re essentially restricted, in some cases, to use only the application in which the embedded license is supporting and there’s typically usage boundaries of the embedded license that are negotiated during purchase.
Again, there is no technical difference, but traditionally there are licensing definitions and/or restrictions on embedded versus full use.
