NEWS:
January 13th is set for a 3 week shutdown at the most recent planning meeting.
Also there could be another shutdown in June. This is mainly
driven by accelerator schedule. We need to study if the 3 weeks is long
enough to switch over to iFix 3.0. If a mixed states of two versions
(existing one and 3.0) is allowed, 3 weeks could be reasonable time scale.
There was a SVX incident on Sunday. Two Z side ladders were lost due to beam.
DataBase:
There are 2 offline computers which replicate the Oracle database of the
online computer. Replication resumed for one of the offline machine.
We were told that the CAF does not have access to these machines so far.
It was decided we do not change Icicle database structures.
Improving efficiency requires large scale effort in
modifications in Icicle code and browsers. The gain in disk space can
not justify the man power necessary. Also Magherita made some improvements
on database efficiency.
Some people replied for Steve's e-mail on the Icicle database
usage. We were told that muon wall positions and magnetic field measurements
are used frequently.
Trigger Inhibit:
Andy said somehow L00 trigger inhibit was masked off accidently.
We need to talk to Bill Badgett to send 'mask' information to the run control
to prevent this kind of accidents.
COT:
During the weekened the COT low voltage failure caused some problems. First
we do not have Trigger Inhibit for this. Secondly, the CDFGbAlarms button
did not turn to red even if the voice alarm sounded. After the meeting
Aseet fixed the problems.
CLC:
Andrea said the CLC machine has been stable for the last 3 months. He needs
to restart the machine every month or so due to disk space problems.
He does not know what program fills up the disk at the moment.
VNODE1:
Recently, the new batch of aces notice minor problems with the iFIX pictures
at the Vnode1. John suggested that we should make log files associated with
the pictures. Since log files tend to fill up diskspace we need to be
cautious. For the moment we will watch the situation closely.
PLUGHV:
Margherita said the new code with HV control features still
has some problems to solve.
