ATLAS SCCS Planning 25Oct2006
-----------------------------

  9am, SCCS Conf Rm A, to call in +1 510 665 5437, press 1, 3935#

Present: JohnB, Steffen, Booker, Randy, Wei, Charlie

Agenda:

1. DQ2 Status/Web Proxy

    - Maintenance

    Wei has taken over running the service. He will start it running
    under the production account. Also need to make sure Wei's DN is
    registered for ATLAS. Will copy the old installation and run as
    himself first. Then do reinstall with a new version.

    dq2_get would not work with the web server being blocked from
    offsite. Do need to pursue web server approval.

2. DDM Operations Manpower Request

    This does not include the backend file storage. Only about the
    transfering and DQ2. Probably a small fraction of Wei. Should check
    if Len or Booker are interested in doing anything in the area.

3. Grid Account Precreation

    Security requirement is that there is a one-to-one mapping between
    Grid DNs to unix accounts. Can't just take all entries from the VO
    incase it has some problems. Need to understand if we can trust the
    VO. Many other places map all grid accounts to a single unix
    account. We probably want to be able to trust the VO and have all
    US ATLAS group members of the ATLAS VO have access. Need to talk to
    Richard about this.

4. AOB

    - TDAQ Test Farm

    Installed and powered on second floor. Once machine did not survice
    transport. Done from 50 to 49 machines. Only have switch for 47 so
    this is okay. Thanks to everyone!

    On their own VPN. Steffen will manage them. Only issue for SCCS
    will be if power reset is needed.

    - Request from ATLAS Production

    Can we increase our 10 slots to move? Have 4500 jobs in executtion
    just now, mostly BaBar. THere are 10000 waiting to run. Will
    attempt to increase the number to see if it helps.

    - Data Transfer

    The DDM challenge is going rather well except for the Great Lake
    Tier2. Have successfully transfered from CERN to BNL and from BNL
    to Tier2s. Will today transfer back from Tier2s to BNL. After that
    will do some function test.
