I've seen mentions that it's possible to change WebSphere 8.x so that it uses Oracle's JVM instead of IBM's included JVM. Does anyone know how to accomplish this?
It does seem possible but I did not see a method mentioned anywhere that shows how to go about doing this.
It's not possible/supported in the traditional/classic/full profile of WebSphere.
Under what's called the "Liberty Profile" you simply set JAVA_HOME to your oracle JRE.
