Attendance:
David Dagenhart, Daniele De Pedis, Steve Hahn, Andy Hocker, Larry Kirsch, Yeongdae Shon, Margherita Vittone, Marcin Wolter, JC Yun

NEWS:
Accelerator is doing pretty good these days. January shutdown plan is floating now. They say it could be pushed back as far as September. The decision will be made some time early November. There was a security incident. A pc at the Cryo area was running a fileserver. The pc was disconnected from the network as result. Please remember file servers are not allowed in your pc. CDF is cleaning up the B0 3rd floor computer area. Please check and clean up your area.

  • Steve's transparacies on Security and Icicle database
  • ICICLE:
    Since ICICLE takes a large fraction of Oracle database a task force is formed to optimize iFIX data storage. Allan Sill is in charge. Offline replication of the Oracle online database for analysis groups is not complete. Magherita's plot shows that about 20 gbytes/year for iFix information stored into the Oracle database. Currently 1100 tags are stored every 10 minutes. All the tags (14000) are snapshot every hour.

  • Magherita's plot on Icicle usage of Oracle database
  • Trigger Inhibit:
    The swap between CMP and CMX trigger inhibit was due to a typo at the APACS address. The COT_LV inhibit happened for half an hour. It's quite strange since is no known user for this tag at the moment. After the meeting, we decided to dedicate if for the COT low voltages monitored by COT2.

    GAMMA:
    Gamma system display at the 'CDFHVSummary' page is working now.

    DOC's:
    According to John, we made some progress in the iFIX documentation and urges subsystem expert to update them.

    PLUG HV:
    Margherita said she and Luciana are working on the Plug HV control buttons on 'CDFHVSummary'. It needs some tests before we install it.

    VNODE:
    Some people are complaining about the control buttons of 'CDFHVSummay' page. They said it's confusing since the high lighted buttons do not correspond to the status of HV. We agreed to remove the high light features.

    SYSTEM:
    Andy said iFIX 3.0 and new EDA tool kits are ready to be tested at SiDet. Larry strongly argued we need to install VNC at the pc, iFIXTEST, to test it out with 3.0.

    TOF:
    Daniele said the TOF pc never crashed after we switched to a new pc. He said it took about half day to change over from scratch.

    MUON:
    Yeongdae said someone logged into iFIX in at the MUON3 but forgot to go back to the default account. After a while the user timed out and there was no one logged in at all. This stopped monitoring completely. We need to ask Jim Loskot to change the timeout feature to go back to the default user when a user times out.
