Hi, I don't know anything about Mongrel-cluster. 1). you could dig Mongrel-cluster documentation to see if there is a way to communicate between the clustered instances and prevent instances other than instance 0 from using the Scheduler. 2). you could use an empty 'semaphore' file. Each instance would not start the scheduler if the file exists else it will immediately create (touch) the file and the start the scheduler. 3). maybe there is a way for your instances to know that they are instances in a cluster and maybe there is a way for them to know "yes, I'm the first instance", "no, I'm not the first instance" and behave accordingly. 4). avoid all of that but putting the scheduling logic outside of any instance, maybe with code started once, alongside the Mongrel-cluster. I hope this will help, best regards, -- John Mettraux -///- http://jmettraux.openwfe.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "OpenWFEru users" group.
