#####################################################
#
# This script will run a reorg on the DB2 tables
# It is dependent on the setup of DB2 by the db2sqlsetup script
# It is to be set in a cron job on the xCAT Management Node and
# requires xCAT to be installed because it uses xCAT Perl libraries
# and xCAT commands
