   D0 Grid / Remote Computing Meeting in London, 29 April - 1 May
2. Towards the next reprocessing
   
   • Database Proxy, Thomas Nunneman
     (Prototype installation (done), Installation help for other sites, Field test with many sites)
     EDG/LCG people need to investigate how to use this.
   • TMB Merging
     Mike Diesburg provides scripts, Peter Love incorporation into runjob 7. Who is doing runjob 6 (Ian? in case of emergency)
     
     SAM Grid in MC seems to offer a SAM-based solution.
     Merge should be extract to a standalone programme.
     Mike evaluates how it works in detail.
     Need a check which veryfies the TMBs aren´t merged twice. Should be based on SAM metadata/parentage info.
   • Certification procedure? Did we contact Phil?
   • Need someone to work on common (SAM-based?) bookkeeping
     (see TMB merging)
   • Useful Checks to do: NN
   • Staging Node: Standalone node identified with 2TB disks for remote IO (replacement of rp-router).
     Have to think whether we need to seperate off the analysis part.
   • Update of estimated contribution.
3. Preparation of the London workshop
   What do we want to learn?
   • How to merge?
   • Bookkeeping (Who processed what? What failed/needs retry?)
   • Database (for EDG/LCG)
   • Certification
   • Timeline/Decision line
