In this "Exalogic Software Optimisation" blog entry, Paul Done discusses how the JRockit JVM, the latest WebLogic Application Server and Coherence (the secret sauce) all make the Exalogic machine run as fast as it does with the same versions of the products you would use on any other hardware. All three products have been engineered to shine together and on this particular iron.
The difference with other similar software stacks is that these three products really shine when running on the Exalogic machine by using SDP to take full advantage of the internal InfiniBand network. It's also worth mentioning Active Gridlink which was introduced as recently as WebLogic 10.3.4 to offer optimized connections to an Database Oracle RAC cluster (which could be running on an Exadata).
This being Exalogic v1, there is yet more to come to reinforce the technical reality of Oracle's "Hardware and Software, Engineered to Work Together".
