Next: CONCLUSION
Up: ON THE USE OF
Previous: Monitoring Servers and Applications
Several applications, written mainly in
Tcl/Tk or Java,
have been successfully introduced
for the commissioning
and operation of the SLS booster and
storage rings [3],
making ample use of the CORBA
framework provided. Server objects were
extensively tested through
invocations initiated by a variety of
client processes. Operator intervention was
minimal with clients able to interact
spontaneously with the many servers and to
display their event data.
This is exemplified
by the slow global orbit feedback system
(3 Hz sampling rate),
which is both a consumer to event generated data
and a party to remote methods invocations on a
variety of servers.
A fast version, for which dedicated
low-level hardware is to be installed
(4 kHz sampling rate),
will challenge the reaches of our model [4].
