7. Mirroring (1) Description: Cronjob (each 2h from 0:00);
Remote dump of mysql tables from master Catania database;
ftp download from Catania of all log/err/Config files;
The documentation for the mirroring is available at or in Catania at
ftp://alipc1.ct.infn.it/pub/grid/test/mirroring.ps

9. ROOT Apache Module in Bologna
It was an old idea (without implementation): use the Carrot package to browse remote small size files produced by the quality check on the GRID data;
Documentation for Carrot installation and setup in Bologna is available at

11. PROOF set-up (in progress)
PROOF has been (not yet successfully) set up on 2 TOF-Offline dedicated machines (1 node and 2 slaves)
Some problems concerning the authentication in the slave;
It may be necessary to install the SRP package.

12. Memorandum TOF Requests for the next testbed:
Run GRID simulation using the double stack version of the TOF strip
(may be an AliTOFv5.h/.cxx added to the distribution used for the testbed);
Submitter selection of the Config.C and coordination among production managers;
TPC code performing the storage of the GEANT momentum of the track in the last TPC pad row.
