DATAGRID ConferenceTestbed0 - resources in Italy Luciano Gaido 30 INFN-Grid Resource Database §A database has been created for the resources of the INFN-Grid pool. §The database backend is an XML file. §The database management tool is a java servlet. §All the database management operations are done on the web, through web pages produced by the servlet.

DATAGRID ConferenceTestbed0 - resources in Italy Luciano Gaido 33 XML database backend §XML has been choosen as database backend, because its element nesting capability is particularly suitable to reflect the hierarchical tree-based structure of the Grid resource layout. §Moreover, XML offers an open, freely expandable database schema.

DATAGRID ConferenceTestbed0 - resources in Italy Luciano Gaido 35 Database management tool §The management tool is a java servlet, which uses a simple, non validating, parser to access the XML file, and to convert it into an object tree. §It also generates a set of web pages which allow the user to examine, add, remove and modify unit entries.

DATAGRID ConferenceTestbed0 - resources in Italy Luciano Gaido 36 Testbed0 infrastructure validation - C++ program (C. Anglano, A. Guarise) - simple shell script The script: - performs authorization (grid-proxy-init) - copies the C++ code from the submitting machine to the executing machine - compiles the code - executes the program (5-10 minutes) The output file (~ 1 MB) is transferred back to the submitting machine
