In the KEKB project both ring and linac accelerators are upgraded from
the TRISTAN project. Recently it was decided to employ EPICS control software
for KEKB ring controls. It's reasonable to use such mature collaboration based
software when we start building a new control system. However, at the linac
side, which will be upgraded from 2.5-GeV to 8-GeV, we have been operating a
new control system employing international and de-facto standard systems with
object oriented design since two years ago. Thus we are searching for the
scheme to make these two control systems cooperate each other, since it is
important to have tight control communication between linac and ring in order
to acquire higher luminosity in the physics experiment. In the report, several
schemes for the cooperation between ring and linac are discussed.
