title: Recomended value for org.quartz.jobStore.clusterCheckinInterval
body: <p>We are using quartz scheduler in a clustered environment (Two nodes in a cluster, pointing to a single Oracle database). Currently we have <strong>two jobs</strong> which runs pretty much every one hour.</p>
  
  <p>We have a separate database schema for the quartz jobs. What we've noticed is that quartz checks the database every 15 seconds (default value for <strong>clusterCheckinInterval</strong>).</p>
  
  <p>We don't like this and like to make it less frequest. What we have in mind is to give is a 1 minute frequency, but most of the example configurations has given <strong>clusterCheckinInterval</strong> as <strong>20000</strong>. </p>
  
  <p>Can some body please recommend a suitable value for the clusterCheckinInterval?</p>
  
  <p><strong>From the Quartz documentation:</strong></p>
  
  <pre><code>org.quartz.jobStore.clusterCheckinInterval
  
  Set the frequency (in milliseconds) at which this instance "checks-in"* with the other instances of the cluster. Affects the quickness of detecting failed instances.
