17:00 → 17:20 Site Requirements - what the sites need to know

Speakers: Fabio Hernandez (IN2P3), Gonzalo Merino (PIC), Luca dell'Agnello (CNAF)

Paper CCRC08_-_v2.doc

17:20 → 17:30 Deletion of temporary files after February run

(Was: CDR challenge in December)

From discussion it’s not obvious that all experiments know how to write mock plus real data in a way that mock data can be dropped by the end of the exercise. What measures should be taken to ensure this will work? Should we have a small test right now in December? 24h CDR run at nominal rate with a mix of real and mock data? The important step is not the test but obviously the preparation that needs to go into it. Miguel

Speaker: Miguel Coelho (CERN)

17:30 → 17:40 Monitoring, logging and reporting - the proposal

Speakers: James Casey (CERN), Julia Andreeva (CERN)

17:40 → 17:50 The SRM dashboard - site & experiment readiness for production SRM v2.2

Multi-VO site issues

For the sites supporting multiple VOs (the majority) the requested SRM setup must be compatible.

• ATLAS
• LHCb

Additional configuration regarding ROOT access from LHCb:

• Does the SRM endpoint return correct tURLS for data access with ROOT?
• Are there enough connections to WNs enabled on disk servers? (200-300 required: dCache default is 30...)

CERN Status

The Castor SRM v2 production endpoints at Cern have all been configured. They are:

Endpoint VO Space tokens
----------------- -- ------------
srm-alice.cern.ch Alice default
srm-atlas.cern.ch Atlas DISK, TAPE
srm-cms.cern.ch CMS
srm-lhcb.cern.ch LHCb LHCb_RAW, LHCb_RDST
srm-dteam.cern.ch DTEAM srm2_d0t1, srm2_d1t1

All endpoints support OPS and DTEAM, publish their information in the BDII and are monitored by SAM.

Speaker: Flavia Donno (CERN)

17:50 → 18:00 Preparation for the January 2008 F2F (Thursday 10th in 160-1-009)
