[Building Sakai] Quartz in clustered environment

[David Haines]

Hi,

   Has anyone got recent experience running Sakai with Quartz clustering
enabled?  We're running into an issue on startup with incorrect
configuration of the ScheduledInvocationManager job that would be explained
by a race condition during startup.  We're starting up 16 servers so we
likely well beyond any tested Sakai configuration.  Running cluster enabled
seems like a good idea given that we are scheduling the same job from many
servers.  If anyone has experience to share that would be appreciated.

We're running Sakai 2.9 with 16 servers and up to 10k simultaneous users.

Thanks - Dave
