My webMethods Server Cluster Considerations
If you are operating My webMethods Server in a clustered environment, some considerations apply to the implementation of e-form support. In the case of a My webMethods Server cluster, do not connect to the Integration Server/Process Engine host through a load balancer because RMI (the method used to communicate) generally does not work in this configuration. Instead, configure a direct connection between a single My webMethods Server node and the Integration Server/Process Engine host.
