# This wrapper script can be used to schedule qperf via crontab
# The script is assumed to be installed in current user's home directory in qperf folder
# interval and iterations can be changed as required
# number of iterations should not exceed crontab duration between two executions 
# i.e. if cron executes two instances at 2 hour interval, iterations should be less than 120
#
# qperf is developed and maintained by Christian Karpp
# It can be downloaded from https://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/TD105947
