Hi,

I’m currently working with backgroundrb and need some help with workers  
triggers.

I have two app servers with the same rails application and one worker  
that executes every day at 00:00. In my backgroundrb config file I setup  
a memcache server for the results sharing, but the work is executing in  
both servers.

My problem is that i had the same job executing twice =(

How i can do a job that only run in only one machine per time? Can  
backgroundrb take aware of this and only run the worker in one machine?

Sorry my bad english,

Cheers!

Finally i’m using the database for sync the process of all my servers  
running backgroundrb. I found intersting things in the “Quartz” project  
that backgroundrb could implement.

Cheers,
