Answer 1

1. Cronjob: The job to be performed. For this Create an item type extending from CronJob.
2. Job: Where the actual cronjob logic will be written. For this Create a class extending from AbstractJobPerformable<...abovegeneratedModel> and override the perform() method. Here perform method will contain actual job logic.
3. Define the above Job class as a bean in xxxcore-spring.xml.
4. Go to hmc-->System-->Right click on Cronjobs and Create your new cronjob.
5. Trigger: Holds cron expression when to fire cronjob. Add the trigger conditions through TimeSchedule tab.
6. Click StartCronJob Now to schedule the cronjob.

You can also use impex script to create trigger as thijsraets said.

INSERT_UPDATE Trigger;cronJob(code)[unique=true];cronExpression
;myCronJob;30 23 14 2 5 ? 2015

MANY THANKS MANOHAR. What are the options for creating Trigger, other than Impex – Pedicel

hmc-->system-->right click on cronjobs-->select the cronjob you wish to create-->select TimeSchedule tab... there you will find the trigger section --> right click in that section-->create trigger. – Chantry

Many Thanks Manohar, Is Cron Job Linked to Java Thread ? What happens in a shutdown .... if it does not have an active Trigger – Pedicel

What is the use of a cronjob without scheduling it. Trigger contains the scheduling criteria(like at what time to execute). – Chantry

I think, on demand basis we can execute them as and when its needed when there is no trigger. So you can have a cronjob without any trigger. Hope this helps. – Ceja

Answer 2

You probably want this cronJob to perform a custom action, for this you need to link up the cronJob with an actual action/task: the job itself. Create a bean that extends AbstractJobPerformable and implements the "perform" method. Now in the hMC you can create your Cron Job (System->CronJobs), under Job point to the bean you have created.

If you would like to do this from code you can use impex, for instance:

INSERT_UPDATE CronJob;code[unique=true];job(code);sessionLanguage(isocode);sessionCurrency(isocode)
;myCronJob;myJobBean;en;EUR

INSERT_UPDATE Trigger;cronJob(code)[unique=true];cronExpression
;myCronJob;30 23 14 2 5 ? 2015

Assign to a String and import this impex (or just execute in hac):

final CSVReader importReader = new CSVReader(impEx);
final Importer importer = new Importer(importReader);

importer.getReader().setDumpingAllowed(true);
try
{
    importer.importAll();
}
catch (final ImpExException e)
{
    e.printStackTrace();
}
importReader.closeQuietly();
importer.close();

(If you are using 5.5.1: the triggers do not work properly if you indicate multiple execution times. No problem if you only specify a single execution time , we hope SAP will solve this)

MANY THANKS FOR THIS COMPREHENSIVE – Pedicel

just wondering why did you use IMPEX for adding Business Logic. What are the other options .... Bean shell, Interceptor, Java etc are there I believe – Pedicel

You can also use CronJobModel (and set triggers), just thought impex looked transparent – Littleton

well i am certainly not an expert on impex. I am trying to expand my conceptual understanding, but struggling to get the big picture ... where is Impex is used – Pedicel
