In this paper a development of the DOOCS (Distributed Object Oriented Control System) controlled server program was
described. The server supervises the devices working for the FLASH (Free-Electron Laser in Hamburg) accelerator
located in DESY (ge. Deutsches Elektronen-Synchrotron), Hamburg. In the first part, a basics of the devices' working
rules were presented. Afterwards goals of the work and server project's assumptions were described. Next chapters
present all the implementation details along with the trouble-free data acquisition, processing and representation. In the
last chapter the final work effect - DOOCS server was described. The server was repeatedly tested and ran in DESY. It
is important part of the clock distribution system (Master Oscillator).
