Orabpel clustering

Question

Hi,
In the near future, we will deploy our engines in cluster. I have some extra questions:
We'll implement it this way:
1. Install the Oracle BPEL Process Manager Server on two different machines.
2. Set up a load balancer as the proxy for both Oracle BPEL Process Manager Servers.
3. Set up database as the dehydration store for both BPEL Servers.
4. Specify the callback address (soap-server-url) of each BPEL Server to be the
location of the load balancer.
If we want to use a software loadbalancer (e.g. apache), we can't use it for the java api (EJB), however it is important for us to have also failover through the api. Is it possible to point through the API at both engines and will it detect connection problems (connect to the running one at startup)? Could someone give a code example ?
To synchronize the configurations for both engines, is someting foreseen (adapted jsp's, other tool that makes update in both engines), or our we responsible for the duplication of the configuration changes on the other engine?
Thanks in advance for your feedback,
Veerle

Answer 1

I read that the default is round-robin, which i did not set in the props
          file. So i'm not sure why the other JVMs never get hit???
