# Draft script by Roy Wilson used on Redhat6.1 system (bash)
# Assume ONLY HelloWorld servlet being used: better to have a set, but what?
#
# To promote comparability, run script immediately after a cold boot
echo Run script only after a cold boot to make results comparable
echo When done please and post the summary file to Tomcat dev list
echo Usage:
echo sh tcscript servlet-name max-concurrency increment
echo Example:
echo sh tcscript HelloWorldExample 100 10
rm -f summary
sh tcscript 1 $1
load="$3"
while [ "$load" -le "$2" ]
do
echo "Starting ab with load = " $load
sh tcscript $load $1
load=$(($load+$3))
done
# Roy Wilson 11/2/00
echo "Starting ab load test with C = " $1 "and servlet = "$2
rm -f $1$2.sardata
# Next 2 lines may need adjustment on account of OS differences
# Start with a fresh temporary system accounting log file

cp /var/log/savacct /var/log/tcacct
