Re: Best way to run period task?
Hi, What's the recommended way to run a periodic task from within a WO application? In this case its infrequently (hourly) and independent of any web requests. Thanks Mark I use a java.util.TimerTask. The task runs in a separate execution thread. It is pretty simple, and built into Java.

Re: Best way to run period task?
Another vote for quartz! Might be overkill for a simple recurring task but having the flexibility there for the future is great.

Re: [SPAM] Re: Best way to run period task?
we have a dedicated scheduler app (based on quartz http://www.quartz-scheduler.org/) looking after all our repetitive tasks. we run a single instance of it in production, with change notification distributing any changes that other apps need to know about. i believe a few other WO people do the same. simon 2010/1/7 Andrew Lindesay a...@lindesay.co.nz Hi Mark; It depends somewhat on your deployment topology; if you have a number of instances then the timer would go off in a number of instances and your periodic scheduled task may run a number of times. cheers.

Re: Best way to run period task?
Hi! It depends on how long does the task take to run, and how heavy does it hit the DB. For complex stuff, we use dedicated apps. For simple stuff, a Java thread will do, or maybe that wonder class (I didn't know it existed, gonna look at it).

For me...
public class SomeTask extends ERXTimerTask {
public void _run() {
// do something
}
}
long delay = 20;
long period = 86400 * 1000;
SomeTask task = new SomeTask();
Timer timer = new Timer(true);
timer.schedule(task, delay, period);
See http://java.sun.com/j2se/1.5.0/docs/api/java/util/Timer.html

Re: Best way to run period task?
Mark: For simpler tasks I write direct actions then call that DA from curl. Then I set up a cron job to call a simple shell script that runs curl (or other). For security purposes, I check the requesting host in the DA. So, if the request doesn't come from localhost or 127.0.0.1 it doesn't run. This solution obviously doesn't work well if you want to be able to set the schedule within the app. Tim Worman UCLA GSEIS On Jan 6, 2010, at 4:22 PM, Mark Woollard wrote: What's the recommended way to run a periodic task from within a WO application?
