Hi all,

First of all sorry for writing such a big mail.I am facing problem while implementing Piranha Load balancer on CENTOS 4 for my two oracle 11i application server running on linux.

Oracle Real server details

Instance Name - test

url's - 1 . dev.xxx.com:8004 2 . uat.xxx.com:8004

Architecture - Services installed on dev are

1. Database Server 2.Concurrent Processing Server 3. Administration Server 4. Forms Server 5. Web server

And services installed on uat are

1.Web server 2.Form server

Note: Form server running on port 9004 on both hosts.

Piranha details

eth0 192.168.23.2 --- external physical ip eth0:1 192.168.23.3 ---EXTERNAL VIP eth2 192.168.17.125 --internal physical ip eth2:1 192.168.17.121 --INTERNAL VIP

Client Network: 192.168.23.0/24 Real Server Network: 192.168.17.0/24

Client are accessing oracle application using VIP of piranha by http://192.168.23.3:8004/

Real server ips, hostname and gateway

192.168.17.16 dev.xxx.com having gateway of piranha Internal vip 192.168.17.121 192.168.17.17 uat.xxx.com having gateway of piranha Internal vip 192.168.17.121

my ipvsadm rule is like below

192.168.23.3:8004 ---->>192.168.17.16:8004 192.168.23.3:8004 ---->>192.168.17.17:8004

For me load balancing is working fine for http://192.168.23.3:8004/ . But once i logged in when ever i tried to browse any Oracle Application Forms then it is giving me error "Failed to connect to the server" uat. xxx.com:9004

Note: Form server running on port 9004 on my both oracle application sever

when ever i click on any forms it is trying to connect to uat.xxx.com[which is aliased to the VIP of piranha that is 192.168.23.3 in my client host entry] so it is clearly trying to connect to 192.168.23.3:9004 but there is no service or ipvsadm rule on that vip of piranha for that 9004 port.

Note: Telnet to Form server on both oracle apps server is working on 9004 from piranha server.

So i created the ipvsadm rules on piranha on same vip on 9004 port like below. 192.168.23.3:9004 ---->>192.168.17.16:9004 192.168.23.3:9004 ---->>192.168.17.17:9004

But i am getting below error on my syslog

I am not able to see any thing for 9004 whenever i try ipvsdam -L. So i need some one help to solve this issue,i am facing problem only with forms rest of all of my other apps are working fine under piranha.Also forms are working fine whenever i bypassed piranha server.
