We want to deploy Grouper in a High Availability environment and I have a few last questions regarding Grouper’s processes. Here I’m talking about provisioning (LDAPPCNG), the Grouper Deamon (Grouper Loader) and the Group Loader. Is there a way to have those in High Availability ?


What I found in previous discussion is people have the Ui/Tomcat on 2 load balanced Hosts, but only have one server running the Grouper Processes and, should a failure happen, they would start them on the second server. My guess is that it’s still the case, but maybe I’m wrong. Is there any new development or solution for this problem ? Any synchronisation available ?


Maybe one idea would be to have a scheduler/watcher check the first server’s health and if it fails it would automatically start the processes on the second one.




PS. Will all this change with real-time provisioning ? From the quick glance I had from TomZ’s manual it seems the real-time provisioning is in the Grouper Loader so I think my question still stands for this.
