               JobRunMode jobRunMode,
               JobRunDefinitions jobRunDefs)
                 throws RunStorageException

Starts a job run. If another instance already started the job the method will throw an exception.

Specified by:

startJobRun in interface RunStorage

Parameters:

jobName - The name of the job to start.

jobRunId - The job run id for the started job run.

jobRunMode - The job run mode for the started job run.

Called when a job run is finished. This does _not_ remove the job run data. Since it is possible that more instances of a job manager try to finish a job run concurrently the one that succeeded will get 'true' as return value, the others false but no exception will be thrown in that case, because this is not an exceptional behavior.

Specified by:

finishJobRun in interface RunStorage

Parameters:

Returns:

true if the caller was the first to finish the job, false if another caller finished the job in the meantime.
