Jobs that depend on each other...

[zambak]

Hi

Is there a feature in Quartz.net where jobs can depend on each
other...
Actually, what I am looking for is a solution for following scenario:

- there are 2 jobs job1 and job2
- both jobs are scheduled to run indefinatelly
- job2 should not run unless job1 completes with a sucess code...

Is there a way to do this?

Regards
Z...

Hi,

Just seen this in the FAQ:

Good luck

Hi Everybody,

I am trying to chain 3 jobs one after the other (upon successful completion).

How (using the quartz_jobs.xml file) can I configure a job chaining?
Browsing through the code I have noticed the class Quartz.Listener.JobChainingJobListener. Should I use the Quartz.Listener.JobChainingJobListener?
What is the best way to achieve that?

One way is to pass the "next job" details in as parameter(s) to the first job. Code in the first job then creates the job detail and (immediate) trigger as required. A bit messy, but it works.

 

It helps to keep in mind that Workflow is not Quartz's primary objective.

 

JobChainingJobListener is essentially a global listener that awaits completion of a given job and triggers the next job in the chain (all the jobs should be scheduled, but the chained i.e. dependent job should not have a trigger; it's trigger will be the completion of the first job).

 

Using JobChainingJobListener (as I understand it - and I may well be wrong) doesn't allow for checking of successful completion before triggering the "nest job(s)", but triggers only on completion.

 

If you do comm up with a good example or some sample code, please post it back to the group :)

 

Cheers...

Can you please provide me a quartz_jobs.xml configuration sample showing how to cause the JobChainingJobListener to trigger an additional job upon completion?

I use the JobListener which get invoked once the job is executed. The
Job that was executed would set the success/failure in the datamap and
would be read by the JobListener.
