You can use like this :
- workers.properties -

workers.java_home=/opt/IBMJava2-13/
ps=/

worker.wrk1.host=wrk1.cmb.fr
worker.wrk1.type=ajp12
worker.wrk1.lbfactor=25
worker.wrk1.cachesize=1
worker.wrk2.port=8007
worker.wrk2.host=wrk2.cmb.fr
worker.wrk2.type=ajp12
worker.wrk2.lbfactor=25
worker.wrk2.cachesize=1
worker.wrk3.port=8007
worker.wrk3.host=wrk3.cmb.fr
