      Service Interventions in February / Experiment Production 10m
      • New LFC release supporting bulk queries - status
      • Change of SRM host name at TRIUMF
        Hi, The so called "central" lfc is prod-lfc-atlas-central.cern.ch. It is not used by the ATLAS DDM but unfortunately has a legacy role for the users.

        I get confused with acronyms but the indico meeting title I referred to is WLCG-OSG-EGEE Operations meeting

        We thought the hostname change was an internal site issue. We were aware of several hard-wired configurations around the world, e.g. FTS and LFC, and if the change exposed more then that`s a good thing.

        In an ideal world there would be no hard-wired places to change, and thanks to the infosys, it almost worked. The 2 problems I know of FTS config - the design was to use the infosys but the BDII was not reliable enough so the services.xml file was born. LFC SFN - the schema has the hostname buried in the SFN, for reasons I still can`t fathom. If the hostname was a foreign key to a table of SE:hostname mappings then the change would be trivial. At 300,000 entries, it`s still fairly trivial with a 'replace'.

        As I said, in the end the change became urgent due the hardware problems on the old headnode. Apologies if it went too fast for anyone, but better now than during data-taking.

        Cheers, Rod.

      • Preparation for Production Distributed Database Services
        • Downstream capture box - this is just a single box? cluster? that is used for both ATLAS & LHCb applications?
        • RAC expansions - scope / schedule / implications
        • Oracle 10.2.0.3 deployment

        Below the list of services affected with 3 hours downtime for intervention on Tuesday 13 February (or 14th February). Proposed time 9 to 12 CET.

        lcg_fts, lcg_fts_w, lcg_lfc, lcg_voms, lcg_shiva, lcg_gridview, lcg_same, lcg_fcr

        Attached the usage report to WLCG RAC during last 7 days.

        CMSR expansion will be on Week 7 and LHCBR on week 8.
