The first neutron was produced on May 2008, the first muon was extracted on September 2008 and the operation for the first user program started on December 2008 in J-PARC/MLF. The beam power of proton are increasing from 4.3kW to 120kW, the number of the experimental instruments are increasing from 8 to 14. In addition, the constructions of new instruments were started in this year. Many users started the experiments in each instruments and measured the data. Under these situations, the requirements of the MLF computing environment are increased more and more. In this year, we provided the project management server, the trial distributed data processing system, the sample management system with database and Gigabit Ethernet backbone.
