Reprocessing of 2012 data on-going, close to the end with some more merging jobs and re-running of failed jobs.<br>
<ul>
    <li>
        avoided data on FZK Tape as input</li>
    <li>
        affected by &quot;data loss&quot; at T1s&nbsp; ( FZK, NDGF -- disk server incidents, RAL -- power cut )
        <ul>
            <li>
                ATLAS finally started exercising recovery of a job output by running a single job, rather than re-running a whole task (a long-wished function in our prodsys)<br>
                &nbsp;</li>
        </ul>
    </li>
</ul>
Another set or processing of special stream data from tape is to be defined soon (this month).<br>
<br>
follow-up within ATLAS about Frontier raised last week <em>&quot;Frontier: to avoid default TCP timeout in case of service down (<a class="twikiAnchorLink" href="https://twiki.cern.ch/twiki/bin/view/LCG/WLCGDailyMeetingsWeek121119#Wednesday">WLCGDailyMeetingsWeek121119#Wednesday</a>)&quot;</em><br>
<ul>
    <li>
        The Frontier client is configured with a 10 second TCP timeout, and try the next Frontier server on the list quickly if the primary Frontier server is down</li>
    <li>
        i.e. ok to keep the node down, rather than rebooting with a possibility the Frontier server sending a &quot;keep alive&quot; command potentially causing the time to fail and retry to be longer.</li>
</ul>
<br>
points raised at the last meetings to be followed-up
<ul>
    <li>
        GOCDB: WLCG-ops should review the fall-back system / procedure</li>
    <li>
        FTS: affects T2 activities largely. ATLAS requests WLCG-ops to address fall-back solution</li>
    <li>
        VOMS-GGUS synchronization for /atlas/team (<a class="twikiAnchorLink" href="https://twiki.cern.ch/twiki/bin/view/LCG/WLCGDailyMeetingsWeek121029#Friday">WLCGDailyMeetingsWeek121029#Friday</a>)</li>
    <li>
        Need for alert when OPN switches to backup (<a class="twikiAnchorLink" href="https://twiki.cern.ch/twiki/bin/view/LCG/WLCGDailyMeetingsWeek121105#Monday">WLCGDailyMeetingsWeek121105#Monday</a>)</li>
    <li>
        Twiki WLCGCriticalServices to be updated</li>
