Hi,

The Application port is configured in the catalina.properties file

# String cache configuration.
tomcat.util.buf.StringCache.byte.enabled=3Dtrue
#tomcat.util.buf.StringCache.char.enabled=3Dtrue
#tomcat.util.buf.StringCache.trainThreshold=3D500000
#tomcat.util.buf.StringCache.cacheSize=3D5000
SHUTDOWN_PORT=3D-1
HTTP_PORT=3D8030
JVM_ROUTE=3Ddl360x3805.8030

With regard to the HTTPD configuration , the members are  configured in the
another file (balancer.conf) which is included in the httpd.conf

Include /etc/httpd/conf/balancer.conf


BalancerMember http://dl360x3806:8030/custcare_cmax/view/services retry=3D6=
0
route=3Ddl360x3806.8030

Regards,
Adhavan.M
