What do you mean? Alternatives wouldn't work without the compat package
installed as the Sun RPM does not set it up.

With the compat package installed and alternatives set manually, the
links go into manual mode and do not change when newer JDKs are
installed. That means that you can then yum update as often as you want
without having the JDK links change from the Sun JDK.
