The BaBar experiment at SLAC is designed to perform high-precision studies
of the decays of the B-meson, that are produced in e+e- collisions at the
PEP-II accelerator. Since it was brought on-line in May 1999, it is
continuously increasing luminosity approaching designed goal of recording
30 hadronic events per second, or 3*10**8 events per year.
In order to promptly process and store persistently all generated events,
a powerful processing software and hardware is essential. Current estimates
of the number of computing nodes needed by first level reconstruction
range from 200 to 400. Providing correctly configured hardware and
software for physicists' analysis become equally important and even more
complex task.
The part of the system responsible for concurrency issues in this
environment is a database component. The paper will describe performance
studies, chosen hardware and software configuration of the underlying
Objectivity/DB database system used by BaBar Project.
