Does Synchrony have to be started separately from Confluence?

[Logan Hawkes]

I am upgrading Confluence from Server 5.8.8 to Data Center 6.2.3 and I'm having trouble with the Synchrony configration. With Server 6.2.3, Synchrony starts of its own accord when bin/start-confluence.sh is run. With Data Center 6.2.3 Synchrony seems to need to be started separately. That seems counterintuitive. 

To start Synchrony I have to start a java process from the command line. The command is rather large and unwieldly (see below). Is there a better way to do this? Is there a way to have Confluence start Synchrony automatically?

You could just write your own upstart script that calls both the start-confluence.sh file as well as your custom command.

I noticed that Synchrony doesn't seem to stop when I issue the stop-confluence.sh file, so I'm considering a similar approach myself.

[Logan Hawkes]

That seems like the best approach, but I was hoping that Confluence would have a hook or somesuch to do that for me. Considering that the server version starts Synchrony, it seems like a fairly major omission.

[Steven Behnke]

Agreed. You should consider a support case just to get a straight answer from Atlassian. I've had inconsistent experiences with Syncrony. I've spent the vast majority of my time working to get it to proxy correctly and haven't looked deeply into the stop/start scripts yet.
