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.
