I found in the synchrony doc (https://developer.atlassian.com/server/confluence/collaborative-editing-for-confluence-server/) :
The Synchrony Service executable is extracted from Confluence into the home directory. It will be named ‘synchrony-standalone.jar’, and a second java process will be spawned with the above mentioned jar as the entry point.
I have this jar available in the installation dir but when I start confluence, no other process is spawned.
I found a lot of documentation to have standalone synchrony nodes in a specific cluster working with confluence data center nodes but I don't need this kind of configuration.
Is it possible or do I need to run synchrony standalone as a service ?
