Introduction to R-GMA

• Relational Grid Monitoring Architecture (R-GMA)
• Provides Information (which resources are
  available on the Grid) and Monitoring Services
• Developed as part of the EuropeanDataGrid Project
  (EDG)
• Now as part of the EGEE project.
• Implementation of the Grid Monitoring
  Architecture (GMA) from the Global Grid Forum
  (GGF).
• Uses a relational data model.
• Data are viewed as tables.
• Data structure defined by the columns.
• Each entry is a row (tuple).
• Queried using Structured Query Language (SQL).

Relational GMA

• The data model is relational.
• The table definition is globally unique and is
  stored in the Schema.
• The Registry stores the Producers table name as
  well as the URL.
• The data is inserted in the form of a tuple.
• The Consumer gets the tuple from Producer.
• Producers
• publish SQL INSERT
• Consumers
• collect SQL SELECT

R-GMA Components (Server)

• R-GMA Server the server part of R-GMA
  infrastructure that is used by the different
  producers and consumers. It is divided into four
  components
• R-GMA Server
• The server component of the Information System.
  There can be one or several servers per grid
  site.
• R-GMA Schema Server
• The server component that is used for the schema
  in the IS. There is one common global schema
  server for the grid.
• R-GMA Registry Server
• The registry server for the grid. There can be
  one or several registry servers per grid.
• R-GMA Browser
• Browser to browse information of the IS via a web
  browser.

7
R-GMA Components (Clients)

• R-GMA Clients the client part of R-GMA contains
  the producer and consumers of information.
• Generic Client
• A generic set of APIs for different languages and
  command line interfaces that are installed on the
  User Interfaces.
• R-GMA Servicetool (or Service Publisher)
• Client to publish the existence and status of (a)
  service(s). The servicetool is used by each
  service that wants to publish its existence
  status to R-GMA.
• R-GMA Site Publisher
• Client to publish existence of a site. Each site
  must have one R-GMA site publisher.

Mon Box

• The Mon Box metapackage will install on your node
  a R-GMA-based monitoring system collector server
  and a GridICE collector.
• Usually it is possible to configure a Storage
  Element (SE) as both GridICE and R-GMA collector
  server.
• In this case GRIDICE_SERVER_HOST and MON_HOST
  values in the site-info.def of your nodes have to
  be set to the hostname of your SE.
• If you decide to run these services in a
  dedicated node you can use the Mon Box profile,
  and set the two variables to the hostname of that
  node.

Pre-requisites

• Start with a machine with Scientific Linux CERN
  3.0.X installed.
• Verify that these packages are installed and
  properly configured
• Java SDK
• NTP daemon
• ca_GILDA
• voms-vo-eumed
• glite-yaim-3.0.0-
• g-yaim-3.0.0-
• certificate

12
JAVA installation

• JAVA is not included in distribution. Install it
  separately (gt 1.4.2_12)
• http//java.sun.com/j2se/1.4.2/download.html
• gt chmod x j2sdk-1_4_2_13-linux-i586-rpm.bin
• gt./j2sdk-1_4_2_13-linux-i586-rpm.bin
• gt rpm -ivh j2sdk-1_4_2_13-linux-i586.rpm
• Preparing...

13
NTP configuration

• Synchronization among all gLite nodes is
  mandatory. Install ntp if not already available
  for your system
• apt-get install ntp
• Add your time server in /etc/ntp.conf
• restrict ntp-1.infn.it mask 255.255.255.255
  nomodify notrap noquery
• server ntp-1.infn.it
• (ntp-1.infn.it IP 193.206.144.10)
• Edit /etc/ntp/step-tickers adding your(s) time
  server(s) hostname
• If you are running a firewall, you will have to
  allow inbound communication on the NTP port UDP
  123, for example if you use iptables you should
  add
• -A INPUT -s ltNTP-serverIP-1gt -p udp --dport 123
  -j ACCEPT
• Activate the ntpd service with the following
  commands
• Service ntpd stop
• ntpdate ntp-1.infn.it
• service ntpd start
• chkconfig ntpd on
• You can check ntpds status with
• ntpq -p
