This isn't really a Tomcat question I'm guessing but I don't know where else to ask.

In our setup we have multiple Tomcats behind a load balancer. I have a background task that will run once a day, via Quartz. All Tomcats will be using the same war so they will all run the job, but I need it so only one of them runs the job.

I'm looking for ideas for how to implement this. At the moment all I can think of is to use a table in a database with a unique constraint on a column, and each background process tries to insert today's date (yyyy-mm-dd) and the one that succeeds runs the job, and the ones that don't, do nothing.

Thanks
