Week of 060821

Open Actions from last week:

Chair: H.Renshall

Gmod: M.Dimou

Smod: J.van Eldik

Monday:

Log: Nothing

New Actions: Andrea to coordinate database restarts. Jan and Maarten to look at workaround for r-gma producers dying.

Discussion: The Oracle cursor bug workaround of setting a cache size to zero has been found not to work. Instead a mutex option should be turned off. It was agreed to restart the LFC and VOMS data bases from 10.00. gridview data collection dropped over the weekend as producers died. Olof and James have been looking at slow transfers from T2 to CERN and found that routing via HTAR is associated. A suivre. From CMS most of their LCG MC data is in but there is 10 TB to come from OSG T2's which do not publish what FTS needs to work automatically.

Discussion: R-gma producers on CASTOR diskservers are now being restarted hourly awaiting a more permanent solution. Olof reported that the HTAR problem only affects incoming traffic and that he is working with CS group. M.Ernst reported that grouped SRM transfers to CERN, typically of 5 files, from US T2 sites nearly always fail because one of the transfers fails. P.Badino is working on this with Nebraska as a test site and found that push mode works better. Olof reminded that the supported architecture is for T2 sites to store and forward at their T1 sites. M.Ernst agreed CMS will eventually work this way.
