Java Dialog Instance

Question

Hi,
we installed a additional dialog instance for our entprise portal. the instance is up&running, but no one is connected. i can manage the instance in the config tool and added 3 servers. 
do i have to set up a additional web dispatcher?  - like mentioned in this thread How to Load Balance between java dialog instance in BI Portal)

Answer 1

Hi,
When you have your first instance, i.e, the Central Instance, your users should connect to this system via URL like this:
http://<ci_host>:<port>/xxxx
Then the dispatcher in the CI will distribute all the requests to the server node(s) as a kind of load balancing.
While later if you install an additional Dialog Instance, the DI will have its own URL for accessing:
http://<di_host>:<port>/xxxx
and of course the dispatcher of this DI will distritute the requests inside this instance.
So your users can either access the DI or CI directly with the specific URL, or you can configure any load balancer in front
of the two(or more) instances.
SAP WebDispather is just one of the chooses.   --- not the only one.
As you mentioned, you have already 1 webdispathcer, but not sure what it is used for.
While if it is just used for this system, so you can add the DI to to the balancing list, that is it. 
Not needed to install another web dispatcher.
