    Scheduling app to run on one node only

    Mark Dougherty Newbie

      We're in a 2-node cluster environment with various scheduled services. A new application has a requirement to run only one node once a day - our other scheduled apps are fine with running on both nodes and needs to stay that way. In this app's case, the scheduled service is duplicating data in a database due to it running twice daily vs. just once.

      Can I modify my .sar's META-INF/jboss-service.xml (vs. having to modify any JBoss configuration) so this particular app only runs one node? Here's the existing .sar jboss-service.xml:

      <?xml version="1.0" encoding="UTF-8"?>
      <server>
       <mbean code="org.jboss.varia.scheduler.Scheduler" name="com.mycompany.myapp:service=MyScheduledService">
       <attribute name="StartAtStartup">true</attribute>
       <attribute name="SchedulableClass">com.mycompany.myapp.MyScheduledService</attribute>
       <attribute name="InitialStartDate">NOW</attribute>
       <attribute name="SchedulePeriod">86400000</attribute> <!-- every 24 hours -->
       <attribute name="InitialRepetitions">-1</attribute>
       <depends>
       jboss.jca:service=DataSourceBinding,name=jdbc/MyDataSource
       </depends>
       </mbean>
      </server>
      

      Thanks in advance.
