      * *GridKa:* Andreas, Doris
      * *SARA:* Alexander
      * *Triumf:* Jim Li
      * *ATLAS:* Sasha, David Front, Richard 

   * CERN: 
      * *3D:* Dirk, Eva, Zbigniew, Gianni
      * *POOL:* Ioannis
      * *ATLAS:* Gancho, Florbela
      * *LHCb:* Marco
      * *Taiwan:* Dave

   * General announcements:
      * NDGF has already sent the list of database services (see last minutes): Please send a list of the Oracle deployments at the sites to Dirk.
      * Network problems at CERN: protocol negotiation. Eva working on it together with the network people.
      * CHEP sessions on Vancouver. Dirk asks for people who plans to go. There is a BOF session planned a part of the CHEP sessions.
      * Backup and recovery exercise: Barbara offers hosted it at CNAF. Date proposed: 12 and 13 of June. Agenda to be followed up with Barbara. Please let us know of any inconvenience with the date.  
      * Availability of databases on wiki. Zbigniew has developed a prototype to introduce the planned interventions directely by the sites.
      * Tickets through GGUS: connection problems tickets disabled. During next weeks we should check if the assignment is correct. If not, resend to ROC so it can be redirected. Tickets latency is about a couple of hours.

   * Sites status
      * Tier 0 network problems - see above
      * Triumf iperf tests in order to find and fix the network problems
      * CNAF: intervention 14 may &#8211; maintenance
      * BNL: running smooth, working on the monitoring of the cluster: ganglia, nagios. GGUS ticket latency was 3 hours
      * SARA: one of nodes went down during the morning: full file system. Propagation is reporting a problem with the listener on instance number 1 and cannot connect to the destination queue. Eva just moved the queue and the apply to the available node.
      * GridKa: no interventions, ORA-600 error on the database, Andreas will look on metalink.
      * Taiwan: test with the backup and recovery, working on monitoring

   * Experiment status
      * ATLAS:
         * Preparation to add BNL to the production setup ongoing. We will wait until the network problems are fixed. 
         * NDGF was tested during 24 hours very successfully. 
         * Scalability test will start end of May &#8211; new release of the sw. Client boxes already arranged.
        * Readback jobs running by Richard: some problems with the queries &#8211; being analyzed. Optimizator seems to not pick the right execution plan: full index/table scans. General application problem, not related to the destination sites.
      * LHCB:
         * Waiting for PIC to be joined. Eva has already requested access to PIC LHCb database from the downstream database, but Luis is on holidays.
         * Sw to submit jobs from the grid is ready

   * Stress testing of Tier 1 replicas with ATHENA
      * David Front&#8217;s presentation &#8211; slides available on the agenda.

   * Frontier/CMS
      * No news from the CMS side.
