Batch Process Arguments/CronJob not executing

gldni · September 8, 2009, 8:15pm

I’m are trying to set up a batch process to run jobs on the start-up of my program. I’ve looked through the forums and found threads with similar problems and I’ve tried the suggestions, but am still having problems getting my batch process to recognize arguments.
Here is how my process is setup:
Solution: mySolutionName
Args: true
User: myUserName
Startup Msg: -empty-
Status: Is running

Here is my open method:

function Program_Open()
{
	var isBatchProcessor = arguments[0];
	
	//Set global date and time fields
	var date = new Date();
	globals.g_Current_Date = utils.dateFormat(date,"MM/dd/yyyy");
	globals.g_CC_Box2_Wait_Time = date;
	globals.g_CC_Box3_Wait_Time = date;
	globals.g_CC_Box4_Wait_Time = date;
	globals.g_CC_Total_Wait_Time = date;
	
	if(isBatchProcessor)
	{
		//Updates qtab_encounters timer
		plugins.scheduler.addCronJob('Qtab In Room','0/3 0 * * * ?',globals.Qtab_CC_Update);
		//Updates CC Box 2 timer
		plugins.scheduler.addCronJob('Wait Time','0 0/1 * * * ?',globals.CC_Update_Box2_Time);
		//Updates CC Box 3 timer
		plugins.scheduler.addCronJob('Room Time','0 0/1 * * * ?',globals.CC_Update_Box3_Time);
		//Updates CC Box 4 timer
		plugins.scheduler.addCronJob('Checkout Time','0 0/1 * * * ?',globals.CC_Update_Box4_Time);
	}
	else
	{
		plugins.dialogs.showErrorDialog("Didn't Work","isBatchProcessor = " + isBatchProcessor,"OK");
	}

My variable isBatchProcessor always returns “undefined.” Could someone show me where I’m getting off course?

Thanks,

Hi Nicholas,

I use startup arguments also in my batchprocessors, but you don’t get them as a function argument.
Try to use the following:

var args = application.getStartupArguments()
var isBatchProcessor = args[0];

Hi Martin,

I tried your suggestion and am now getting the following error:

TypeError: Cannot read property “0” from (C:\Users\Nicholas\Documents\servoy_workspace\eClinic\globals.js#2333)
at C:\Users\Nicholas\Documents\servoy_workspace\eClinic\globals.js:2333 (Program_Open)

Do I have the Args setup properly in my batch process?

Thanks!

martinh · September 9, 2009, 3:49pm

Try the following:

var args = application.getStartupArguments()
var isBatchProcessor 

if (args && args[0])
   isBatchProcessor = args[0]
else
{
   application.output('No argument')
   isBatchProcessor = false
}

gldni · September 9, 2009, 4:06pm

When running this through the debugger the first line of code, var args = application.getStartupArguments(), var args returns null. I’ve looked in the Server Admin Guide and noticed when they list arguments for the batch process the arguments are in brackets: arguments[0]. I tried using arguments[true], but couldn’t get that to work. I found a post that suggested just listing the argument. That is what I’m currently doing. In the batch process my Args: true. Is that correct?

Thanks for your help.

gldni:

That is normal. In debugger you don’t have startup arguments

gldni · September 9, 2009, 4:56pm

Martin,

I appreciate your help and patience. I turned off debugger and started my solution. The console still shows “No argument”. I don’t know why I’m having so much trouble with this.

gldni · September 9, 2009, 9:03pm

With your help we figured it out. We were testing locally instead of from the server. Thanks for your help!

gldni · September 14, 2009, 8:03pm

I was having trouble understanding Batch Processor arguments, but martinh helped me see what I was doing wrong. Now my problem is getting my CronJob to execute. For testing purposes, I have a global method that sets a copyright field to “2009”.

function Test_Method()
{
	forms.DEV_Preferences.copyright = "2009";
}

My batch processor is setup like so:
Soloution: eClinic
Args: true
User: userName
Startup Msg: -empty-
Status: Is running

If I leave the CronJob out of my Program_Open method, this works fine:

function Program_Open()
{	
        var batchProcessor = arguments[0];
	if(batchProcessor == "true")
	{		
		globals.Test_Method();
	}
}

When I add the CronJob, it’s almost like the batch process doesn’t fire:

function Program_Open()
{	
        var batchProcessor = arguments[0];
	if(batchProcessor == "true")
	{		
		//Remove jobs
		plugins.scheduler.removeJob('Test Job');
		
		//Create Jobs
		plugins.scheduler.addCronJob('Test Job','0/15 0 * * * ?',globals.Test_Method);
	}
}

Without the CronJob the copyright field changes to “2009”. With the CronJob, the copyright field never populates.

I found this in my server log:

Any ideas?

gldni · September 14, 2009, 8:59pm

After more testing, I have discovered that using “addJob”

function Program_Open()
{   
   var date = new Date();
   var batchProcessor = arguments[0];
   if(batchProcessor == "true")
   {      
      //Remove jobs
      plugins.scheduler.removeJob('Test Job');
      
      //Create Jobs
      plugins.scheduler.addJob("Test Job", date, globals.Test_Method, 15000);
   }
}

instead of “addCronJob”

function Program_Open()
{   
   var batchProcessor = arguments[0];
   if(batchProcessor == "true")
   {      
      //Remove jobs
      plugins.scheduler.removeJob('Test Job');
      
      //Create Jobs
      plugins.scheduler.addCronJob('Test Job','0/15 0 * * * ?',globals.Test_Method);
   }
}

works great. So either I have my CronJob setup incorrectly or it could be a bug…?

martinh · September 15, 2009, 7:13am

function Test_Method()

{
forms.DEV_Preferences.copyright = “2009”;
}

Setting a form field in a headless client???

gldni · September 15, 2009, 3:35pm

I’m setting the field just so that I can see that the batch processor is doing something. I have CronJobs that keeps track of patient wait times. Waiting Room, In Exam Room, Checkout, etc. I made sure the CronJobs worked in Developer, then made it a batch process to call my method so I could test it using the servoy client. When the method containing the CronJobs is called by the batch process, my patient wait times don’t calculate. In trying to figure out why my jobs aren’t working, I’ve taken out the time calculations and resorted to something simple like assigning a value to a field. That is why I have my test method that sets a copyright field to “2009”. Ultimately, I won’t be doing anything like this within the batch process. I was just wondering why using a addCronJob caused the method to stop working. And why it works when I use addJob. Did I clear anything up or just muddy the water?

martinh · September 15, 2009, 3:37pm

I don’t know what the effect is when you access a form in a headless client.
So I try to avoid this

gldni · September 15, 2009, 3:52pm

Can you tell me a better way to get my desired result? Basically, I need all clients to see these patient times. I need the times to update every minute, that is why I thought having CronJobs run in a batch process would be best.

Thanks again for all your help. It is greatly appreciated.

martinh · September 15, 2009, 3:59pm

Use a foundset without a form.

foundset = databaseManager.getFoundSet('yourserver', 'yourtable')
foundset.find()
foundset.pk_field1 = pk_value
foundset.search()

foundset.copyright = 2009

databaseManager.saveData()

But there is a problem with Servoy in databroadcasting where updates from headless client are not visible on other clients.
Adrian McGilly has created a sample and gave that to Servoy, but as far as I know this issue was not fixed in 4.1.4

So it can be possible (perhaps you don’t have the problem) that the value is not shown on other clients.
Of course after quit client and restart client, then it will be visible

Yes you can access to forms in headless client. Servoy forms (and elements) are ‘headless aware’, the problem lies in beans and such that aren’t.

Hope this helps.

gldni · September 16, 2009, 3:12pm

Thanks Robert. Now I know why I’m getting a treeView error in my log. I was still not able to get the CronJob to work properly. I’m looking into alternative ways of increment my times by one minute.

nromeou · November 5, 2009, 4:45pm

Im having a similar problem with the CronJob i use it in my application to run some global method every second.
if i run it from the developer it works just fine, but when i run it from the client then its no use the method is never executed unless i log in my PC with administrator profile, then it works just fine. This makes me think of a permission trouble, perhaps firewall blocking something the scheduler uses to call the method but im not sure, still trying to figure that out. So if anyone knows what could it be id appreciate some help
Thanks

Hi everybody

I’m having apparently the same issue.
When I start the Batch user I get the following error in the logs:

And then the scheduled method is not called apparently. Nothing happens.

The errors seems to be linked to the DBTreeView bean. Indeed, I’m using it in the solution but not with the Batch user. :roll:

I’m using are CronJob and I have implemented it like in this presentation: http://www.servoy.com/servoyworld/sw_do … essors.pdf

jcompagner · January 21, 2010, 12:02pm

so you have a batch process thats a headless client so doesnt have a ui
But you have a form there with a bean and so on?

what does that exactly do in a headless batch processor client?
