        EGEE Items
        • a) <big> Grid-Operator-on-Duty handover </big>
          From: SouthWestern, UK/Ireland
          To: France / CentralEurope

          Issues: quiet week, no problems - can't specify anything important as the COD dashboard is inaccessible right now.
        • b) <big> PPS Report & Issues </big>
          PPS reports were not received from these ROCs:
          AP, FR, IT, NE, RU, SEE
          Issues from EGEE ROCs:
          1. SAM UI at Cyfronet has been configured to submit jobs also to uncertified PPS sites(ticket #28436).
            There was a problem with permissions on lfc02.pic.es, which cause failure of RM tests for all sites - fixed (ticket #30035). [CE ROC]

          Release News:
          1. gLite 3.1.0 PPS Udate 11 is about to be released to PPS sites (due today)
            Notably it contains, together with the usual bug fixes, the new VOBOX service for SL4 (32 bit)
            glite-yaim-core has been released, all the metapackages have been updated.
        • c) <big> EGEE issues coming from ROC reports </big>
          1. ROC-DECH
            SAM tests for SRM are currently only submitted every two hours. Can this frequency be doubled?
        • d) <big> gLite Release News</big>
          gLite 3.1 Update 07 included patch #1389, an update to GFAL/lcg_util. A serious problem has been found with this patch, whereby lcg-cr segfaults with a classic SE endpoint;

          GGUS:32016

          Consequently, this patch has been removed from the production repository. Sites which have not yet upgraded will not be affected, but sites which have already upgraded to the affected rpms should do the following

          <verbatim> # rpm -e --nodeps GFAL-client lcg_util CGSI_gSOAP_2.7
          # yum update glite-WN </verbatim>

          This will roll back to the earlier versions. For the record, the rpms removed are;

          • GFAL-client-1.10.5-1.slc4.i386.rpm
          • lcg_util-1.6.4-1.slc4.i386.rpm
          • CGSI_gSOAP_2.7-1.2.1-2.i386.rpm
          The release team apologises for this situation.
        • e) <big> Proposal to stop using dteam VO in SAM monitoring </big>
          For historical reasons some of the standard, regular submissions of SAM tests are being carried out under the dteam VO. We would like to stop doing this and have everything under the OPS VO by next Monday (17 December).
          Anyone with an objection to this should contact sam-support@cern.ch before Friday 14 December.
        • f) <big> Upgrade of CERN AFS UI from ggLite 3.0 to gLite 3.1 </big>
          As announced on Monday, 22 Oct 2007, the default version of the AFS UI will be changed from gLite 3.0 to gLite 3.1.
          In practical terms this means that the 'current' AFS UI link will not point to the latest 3.0 version anymore, but to the latest 3.1 version.
          The change will happen this Wednesday, 12 Dec, 2007 10:00 CET (09:00 UTC)
          An EGEE broadcast will also be sent out today to announce the change.
