I’m feeling totally at sea trying to figure out how to get clustering up and running. The XWiki docs say to create an XML file, but the referenced JGroups documentation goes into detail about almost everything except about how to create such a file. Is there a sample file available appropriate to a typical XWiki multi-server environment?
In a fault tolerant situation, if a new server comes up to replace a fallen one, will it be sufficient for the new server to simply have a copy of the XML in the right place for the cluster configuration to stabilize around the new collection of servers?
