Change number of retries and interval in job fail retry

heldergr — Wed, 16 Oct 2013 17:45:01 GMT

Hi all,Im trying to change the default number of retries and the invertal between the retries of a failing job but I could not have success. My attempt is based on the what was suggested in the following links: - http://forums.activiti.org/content/job-retry-defaults- https://jira.codehaus.org/browse

> The first is what is the correct strategy to change the interval between retries? Which method in Job (or another class) should I use?

The JobExecutor has these properties:

<code>
protected int maxJobsPerAcquisition = 3;
protected int waitTimeInMillis = 5 * 1000;
protected String lockOwner = UUID.randomUUID().toString();
protected int lockTimeInMillis = 5 * 60 * 1000;
</code>

The job executor is pluggable, you can inject a subclass of your own. I guess the waitTimeInMillis applies for time between retries.

That's pretty tricky as it is not configurable out of the box. However, there is the SetJobRetriesCmd you could use to fix it quickly.

If we overried JobExecutor and SetJobRetriesCmd, it will effect for all service tasks of our model, right?
If I want each service task has a different number of retries and interval, can I do it? how if yes?
If I want to retry until task success (don't limit the number of retry), can I do it? how if yes?

Thanks

Hi,

If I want each service task has a different number of retries and interval, can I do it? how if yes?

Yes it is feasible. You have to just extend process model and to service task optional extensionElement (there are many examples in the activiti code). After that you have to change JobExecutor behavior to take into account your extensionElement when setting job retries.

If I want to retry until task success (don't limit the number of retry), can I do it? how if yes?

Yes, your custom logic in the job executor has to take care of that.
