Introduction

JobScheduler The JS7 Controller and Agent will restart jobs in a number of situations:

• restart job after termination with error.
• restart job after Agent restart.
• restart job from different a next Subagent in an Agent Cluster in case that the Subagent running the job becomes unreachable.

Error

If a job terminates with failureerror, this includes that the Agent is available and is a witness to the job's failure.

...

If a job fails then the order is put set to the failed state. While waiting for the next try in a Retry Instruction, the order will be set to the waiting state.

Jobs on Restart of same Agent after Crash

If an Agent becomes unreachable while executing a job then this can mean indicate that

• the Agent is not running, for example due to after a crash.
  • In case of Agent crash the JS7 - Agent Watchdog will terminate running jobs provided that the Watchdog is active.
• the Agent continues to run, but no connection can be established, for example in case of network errors.

...

If the Agent is restarted after crash then it will restart any jobs that were running at the point in time when the Agent crashed.

• This applies to Standalone Agents and to Subagents in an Agent Cluster.
• Jobs that must exclude the risk of double job execution can can be exempted from restart if they are marked not being restartable:

Jobs from next Subagent after Reset

In an Agent Cluster in case that a Subagent becomes unreachable there is the option to confirm loss of the Subagent and to restart jobs from a users find the operation to reset the Subagent. This will cause jobs to be restarted from the next Subagent.

• The Manage Controllers/Agents page offers the Reset operation on individual Subagents. The Director Agent will consider this information and will restart jobs from the next Subagent.
  The option
  • Note: The Reset operation has to be applied to the related, unreachable Subagent, not to the Director Agent.
  • The operation should be handled with care as it can cause double job execution if the
  original
  • unreachable Subagent is
  unreachable but is
  • still running the job. Before using
  this option
  • the Reset operation users should verify that the Subagent is
  down
  • not running.
  • Jobs which are not restartable after a user confirmed loss of the Subagent can be marked as such in the job inventory. This applies to jobs that must execlude any risk of double job execution.Selection of the next Subagent is based on the type of Subagent Cluster, for example fix-priority or round-robinthat must exclude the risk of double job execution can be exempted from restart if they are marked not being restartable:.
