Manual step (should be integrate in the automatic procedures)

• Change the cron job glite-wms-purger.cron for the purger using this one:

HOME=/
MAILTO=root@localhost

# Execute the 'purger' command at every day except on Sunday with a frequency of one hour
# if and only if the percentage of allocated blocks is greater than 40%
0 */6 * * mon-sat root . /opt/glite/etc/profile.d/grid-env.sh ; $GLITE_LOCATION/sbin/glite-wms-purgeStorage.sh -l $GLITE_LOCATION_LOG/glite-wms-purgeStorage.log -p /var/glite/SandboxDir -t 604800 -a 40 > /dev/null

# Execute the 'purger' command at 4:00 AM, 8:00 AM, 12:00 noon, 4:00 PM,
# and 8:00 PM (0 */4) on each Sunday (sun).
0 */4 * * sun root . /opt/glite/etc/profile.d/grid-env.sh ; $GLITE_LOCATION/sbin/glite-wms-purgeStorage.sh -l $GLITE_LOCATION_LOG/glite-wms-purgeStorage.log -p /var/glite/SandboxDir  -t 604800 > /dev/null

• Run $GLITE_LOCATION/sbin/glite-wms-purgeStorage.sh one time to create the /var/glite/wms.proxy first time

• Create a cron job to rotate wmproxy logs glite-wms-wmproxy-logrotate.cron (first copy /opt/glite/etc/wmproxy_logrotate.conf.template in /opt/glite/etc/wmproxy_logrotate.conf.template and modify it if necessary):

HOME=/
MAILTO=root@localhost
0 */2 * * * root /usr/sbin/logrotate -v /opt/glite/etc/wmproxy_logrotate.conf >> /var/log/glite/wmproxy_logrotate.log 2>&1

• Create a cron job lb-purger.cron to clean periodically LB databases (set the right name of the LB server):

#! /bin/sh
GLITE_LB_EXPORT_BKSERVER="<LB SERVER NAME>"
# run every day at 01:00
0 1 * * * glite . /etc/profile.d/grid-env.sh ; $GLITE_LOCATION/sbin/glite-lb-export.sh >> /var/log/glite/lb_purger.log  2>&1

First apply these changes to $GLITE_LOCATION/sbin/glite-lb-export.sh
