SAP HR in cluster

Hi all,

I am working with the SAP HR driver and the publisher and subscriber channels work fine whent it connect to a SAP host.

In the production environment, the customer has a SAP cluster for load balancing and fault tolerance. Each node of cluster has different IP address. But each node groupped with common IP as cluster IP. This cluster IP is not a SAP instance.

If I configure the JCO client to any node works fine but I can´t connect to the the "gateway" server. They told me that you need to modify the JCO´s configuration to connect to this architecture and use Logon Group instead of the SAP System Number. I don´t see this parameter in the driver.

Any idea?

Thanks and regards,

Luis
