NEWS:
The Accelerator is doing pretty good these days. They promised us to have
average initial luminosity of 10E32 after the shutdown, which starts on
August 23 for 15 weeks.
SYSTEM:
We ordered 2 PC's to upgrade servers. These are equipted with a special
multidisk system for easy recovery from disk failures. Two machines cost
about $8000.
VNODE:
The HBM button turned red few times during the last week at the Vnode1.
HBM stands for Heart Beat Monitoring. When the heartbeat checking program
, which is running in background mode, is updating tags slower than 5 minutes
it turns red. During the normal operation it supposed to update every
1.5 minutes.
Aces are informed to
page an expert for the case when the HBM botton are red for ten minutes or
longer. A power cycling of the VNODE1 solves the problem most of the time.
ICICLE:
Magherita modified her code to write time stamp every 1 minute at the VNODE1.
The known heartbeat problem should be fixed. During the recent study of J/Psi
mass shift of 1MeV, we learned that most of the Solenoid tags stored in the
Oracle database are obsolete.
An updated list of tags are sent to Margherita for installation.
