Introduction

The following example is a more complex version of dynamic setting of remote JobSchedulers. It is just an extension of the basic principle, that is described in:

...

function spooler_process() \{

    var remote_scheduler_list = String(spooler_task.order.params.value("remote_scheduler_list"));
    var parameters = spooler_task.order.params;
    if( parameters.count > 0 )  \{
       spooler_log.info( "Parameters given" );
    \} else \{
           spooler_log.info( " no Parameters given" );
           \}
    
	    spooler_log.info( " remote_scheduler_list : " + remote_scheduler_list );
	    var valuePart = remote_scheduler_list.split(",");
        spooler_log.info(" valuePart.length :" + valuePart.length)

    	for ( var i = 0; i < valuePart.length; i++) \{
	       spooler_log.info( " valuePart : "  + valuePart[i]);              
    	    var order = spooler.create_order();         
    	   	var variable_set = spooler.create_variable_set();
 	        variable_set.set_var("scheduler.remote_scheduler", valuePart[i]);
           
            spooler_log.info(variable_set);
    	   
           order.params = variable_set; 
           var order_secs = 10 * i;
           spooler_log.info( " order_secs : "  + order_secs); 
           order.at = "now+10";        
	       spooler.job_chain( "MY_JOB_CHAIN").add_order( order );             
      	\}

    return true;
\}

The Job Chain

This is a simple JobChain just using the Job defined above.

Configuring the example in your environment

There are just two things that you should configure to make this example run in your environment:

• The Job:
  In the last line "MY_JOB_CHAIN" is the name of the Job Chain you want to send the orders to (in the main JobScheduler).

  Code Block
  language javascript

...

• for ( var i = 0; i < valuePart.length; i++)

...

• { spooler_log.info( " valuePart : " + valuePart[i]);

...

• var order = spooler.create_order();

...

• var variable_set = spooler.create_variable_set();

...

• variable_set.set_var("scheduler.remote_scheduler", valuePart[i]);

...

• spooler_log.info(variable_set); order.params = variable_set; var order_secs = 10 * i; spooler_log.info( " order_secs : " + order_secs); order.at = "now+10"; spooler.job_chain( "MY_JOB_CHAIN").add_order( order );

...

• }

• The Order Parameter:
  Configure your own hosts and ports for your environment. You can configure this in JOE. Alternatively, the list of hosts and ports can be edited in the XML file RemoteSchedulerOrder,ServerGroup.order.xml:

  Code Block
  language html/xml

...

• <params> <param name="scheduler.remote_scheduler" value="HOST_1:PORT_1,HOST_2:PORT_2" /> </params>
