[midPoint] Persistent Tasks

[Samu Viitanen]

After more thorough investigation I noticed that the Task is executing correctly. The task is suspended only in situations like: shutting down the Connector Server machine or a similar persistent situation. If the connector server service running on the machine is shut down, an error message is shown and the task indicates a red circle with a dash in it, but it is still running as Pavol explained. When the service is brought back up, the synchronization continues normally. I have not tested what would happen if the AD machine was shut down, but the AD machine shutting down would be a catastrophe anyways.

I did not file a bug, I will keep monitoring the situation to see if there really is a bug.

    Samu,

      

      this is a clear bug. It shouldn't show "Suspended" in this
      situation. Please, could you log it into jira? (with "how to
      replicate" indiciation?)

      

      Thank you

      PAvol

      

    
    
      
      Hello Pavol,

        

        Thank you for your quick response. Now that I investigated my
        logs a bit more, I noticed that the sync task is indeed still
        trying to connect to the AD, it just shows "Suspended" in the
        administration interface. I think I can continue with my
        implementation. Thank you for clarifying this for me.

        

        Maybe the UI should show something else than "Suspended" when a
        transient problem happens.

        

        BR,

          Hello Samu,

            

            a task should go into a "suspended" state only if the
            problem that occurred is believed to be a persistent one.
            Transient problems like "AD down" should not result in the
            task being suspended - i.e. the synchronization task should
            report an error, but it should continue trying.

            

            There might be a bug in midPoint that incorrectly treats
            such an error. Or, maybe, the connector reports the problem
            in a wrong way. (This midPoint-connector-resource interplay
            is sometimes quite tricky.) 

            

            Would you please share your log file for us to diagnose the
            problem further?

            

            Best regards,

            Pavol

            Hello,

              

              I came across an issue where I would like a
              synchronization task to be "persistent" meaning it would
              attempt to resume the task every once in awhile in case it
              was suspended. I do not want to use the administration
              interface to restart suspended tasks. I understand that it
              might be stupid to keep resuming a broken task, but if an
              AD is down for example, the task would never resume even
              if it came back up? Is this possible currently in
              midPoint?

              

              BR.
