How can I share a Controller Service between process groups? I built a DBCPConnectionPool and use it in a process group. I need it in another process group. In a nutshell, I want one DBCPConnectionPool at root and use it in process groups.
Create the process group in the parent process group of the groups you want to share it in. For example, if you create it on the root group (top-level canvas), it would be usable by any sub-process groups.
