Start checkboxes

For the currently selected station in the Application Director, you can enable (check) or disable (clear) two start settings using checkboxes, as shown above. Typically, for any JACE station you enable both checkboxes. In certain troubleshooting scenarios, you may clear Restart on Failure in order keep the station from constantly restarting after successive failures.
 
NOTE: Changes reflect in the corresponding column of the Application Director’s “installed applications” area.
 

The two start settings for a station are as follows:

  • Auto-start

    Specifies whether the station starts following platform daemon startup. This means following a host reboot, perhaps as a result of a power cycle, but possibly from a Reboot command.

     
    NOTE: For any JACE controller, a reboot also occurs following any installed dist file(s), as well any TCP/IP-related changes. However, installing new modules from the Software Manager—say, for a new driver, does not always result in a reboot (yet in a few cases, in order for a module to become effective, a reboot may be required—and so is prompted following the module install). At the same time, note that changing any existing module (upgrading or downgrading) always results in a reboot.
     
  • Restart on Failure

    Specifies whether the platform daemon restarts the station if its process exits with a nonzero return code (e.g., engine watchdog had killed the station because of a “deadlock” condition).

     
    NOTE: JACE controllers cannot have a station restart without a reboot. Therefore, if this setting is enabled on such a JACE, if the station fails (terminates with error), the controller reboots. If the controller continues to have 3 "automatic reboots" like this within an hour (or however many specified in the station's PlatformService "Failure Reboot Limit" property), it remains in a "Failed" state, regardless of the setting above.
