Method Detail

recoverInstances

public void recoverInstances()

Re-create an instances that should be running as at now. Currently, if the end window for a job has passed, or the start window is future to now (which is common of 1 * * ... i.e. every minute) then instances are not brought back to life, which means events gathered on the agents for old instances will cause issues on the scheduler. Likewise, if the dashboard has been down until after the plan has ended, all the status information will be lost.
