# spooldumps.sh:
#   Schedule overnight job to perform nightly tape backups
#   (This is so the dump processes cannot get into possible
#   locking conflicts with active overnight jobs)
#

#
# Check if dumps job has already been spooled (allows this script
# to be scheduled for multiple runs via cron for redundancy):
#

if isonite.sh zdumps
then

# Change to the /u3/Backup directory, where utility scripts reside,
# and spool the dump.sh master script:

cd /u3/Backup
