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.


31


32


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.


34

XML database architecture

<GRID> <ORGANIZATION name=“INFN”> <UNIT name=“Bari”> <GIIS>giis.ba.infn.it</GIIS> <GLOBUS>1.1.3</GLOBUS> <PERSON>Giorgio Maggi</PERSON> <CLUSTER> <CPU units=“4”>Pentium III></CPU> <OS>Linux RedHat 6.2</OS> <NODE>gris1.ba.infn.it</NODE> <NODE>gris2.ba.infn.it</NODE> </CLUSTER> </UNIT> </ORGANIZATION> </GRID>


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.


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
