EP 7.0 - Web Dispacther necessary

[Former Member]

Hello togehter,

i have only one simple question

We have a Portal with a Central Instance and a Dialog Instance on two diffrent hosts. I read a lot of post`s to Web Dispatcher and Load balancing, but i understand any message diffrent.

Is a Web Dispatcher necessary to distribute the traffic on both server or is this done with the option "HeterogeneousLoadBalancing=true" in the Visual Admin?

We have in the next days a load test, and we will insure against this fault to run the whole load only on the Central Instance.

Thank you!!

Hi,

Java Dispatcher load balancing will balance load between different java instances only.

As you said "HeterogeneousLoadBalancing=true" will come as a feature under Java Dispatcher load balancing especially with cluster environments.

Web dispatcher load balancing will banalce the load on a whole for both ABAP and JAVA instances based on their capacities.

For example

The capacity of an ABAP instance depends on the number of configured dialog work processes.

The capacity of a Java Instance depends on the number of Server Processes

If you are using only java instances, then is works the same if you apply load balancing on web dispatcher or Java dispatcher.

Please award points if this is helpful for you,
