FP6−2004−Infrastructures−6-SSA-026409 E-infrastructure shared between Europe and Latin America First EELA Grid Tutorial for user and system administrators 7 Configuration Configuration comes through the execution of pyhton scripts, which takes as input xml files. So services have to be configured by editing these xml files Xml files are provided as templates, under / opt/glite/etc/config/templates Copy templates file to /opt/glite/etc/config glite-global.cfg.xml glite-rgma-servicetool.cfg.xml glite-lb.cfg.xml glite-security-utils.cfg.xml glite-rgma-client.cfg.xml glite-service-discovery.cfg.xml security_checks.cfg.xml glite-rgma-common.cfg.xml glite-wms.cfg.xml

Typically just the JAVA_HOME attribute needs to be changed, put in th location of your JVM security_checks.cfg.xml –Leave it unchanged glite-security-utils.cfg.xml –Just set the cron.mailto attribute value

Then – For each VO you are configuring must correspond an instance in pool.account.basename : name [prefix of pool user accounts] pool.account.group : name [prefix of group for pool user accounts] pool.account.number : xx [ number of pooled user to be created ]
