Hi to all.
I'm using Tomcat 6.0.26 on RHEL 5.6 machine and Apache 2.2.3.
I don't understand if the jvmroute for stickysession must be unique!
My scenario is this:
- two machine
- two tomcat instance per machine
- proxy balancer on apache actived and connected with tomcat in full mesh
So I have:
- node01, node02 (the machines)
- istance01, instance02 on node01 and node02
Tomcat instances are not configured for Cluster/Session Replication.
On each tomcat instance I setted jvmroute parameter as follow:
a. on node01, jvmroute="istance01_node01" and "instance02_node01" for
instance01 and istance02, respectively;
b. on node01, jvmroute="istance01_node02" and "instance02_node02" for
instance01 and istance02, respectively.
So my Apache configuration for stickysession is as follow:
-----
ProxyPass /myApp/ balancer://balance-this/myApp/
<Proxy balancer://balance-this>
BalancerMember ajp://node01:10505 route=instance01_node01
BalancerMember ajp://node01:10505 route=instance02_node01
BalancerMember ajp://node02:10505 route=instance01_node02
BalancerMember ajp://node02:10505 route=instance02_node02
ProxySet stickysession=JSESSIONID nofailover=On
</Proxy>
-----
And this works fine!
BUT, if I have jvmroute parameter configured with the same value for all
my tomcat instance (e.g. jvmroute="myRoute") and so apache configured as
follow
-----
ProxyPass /myApp/ balancer://balance-this/myApp/
<Proxy balancer://balance-this>
BalancerMember ajp://node01:10505 route=myRoute
BalancerMember ajp://node01:10505 route=myRoute
BalancerMember ajp://node02:10505 route=myRoute
BalancerMember ajp://node02:10505 route=myRoute
ProxySet stickysession=JSESSIONID nofailover=On
</Proxy>

it still works!!! I do not lose my session!
Why??? Have to jvmroute be unique or not??? Remember, I don't use
cluster/session replication feature....
Thanks.
Francesco.
