How to restart a JobScheduler in a cluster after the database connection has been lost

Since JobScheduler release 1.6.4043 the new parameter scheduler.cluster.restart_after_emergency_abort is added.

This parameter controls the behaviour of the JobScheduler in a cluster when it doesn't get a database connection.

Look here for general information about cluster.

Normally a JobScheduler in a cluster shuts down after ca. 2 minutes if the database connection get lost.

Then a new JobScheduler process is started which waits for the database and is back in the cluster when it gets the database connection.

If you don't want that a new JobScheduler process is started to wait for the database then you can use the parameter scheduler.cluster.restart_after_emergency_abort in the ./config/scheduler.xml

  <spooler>  
    <config mail_xslt_stylesheet = "config/scheduler_mail.xsl" port = "4444">
      <params>
        <param name="scheduler.cluster.restart_after_emergency_abort" value="false"/>    
      </params>
    
      ...
        
    </config>
  </spooler>
