CHAPTER 9 Automatically restarting a failed Manager with Manager Watchdog This section provides the following information on starting a failed Manager with Manager Watchdog: Introduction (on page 81) How the Manager Watchdog Works (on page 81) Installing Manager Watchdog (on page 82) Starting Manager Watchdog (on page 82) Using Manager Watchdog with Manager in an MDR configuration (on page 82) Tracking Manager Watchdog activities (on page 82) Introduction The Manager Watchdog feature is designed to restart the Manager if the Manager crashes, potentially bringing the Manager back online before MDR enables. The Manager Watchdog monitors the Manager process on the Manager server periodically for availability. If Manager Watchdog detects that the Manager has gone down unexpectedly, it restarts the service automatically. (It does not restart the Manager if the Manager has been shut down intentionally.) How the Manager Watchdog Works Manager Watchdog runs as a separate process and monitors Manager through the Windows OS Services model. Manager Watchdog polls Manager every 10 seconds. If the Manager Watchdog does not detect the Manager during a polling period, it waits 30 seconds and then restarts the Manager service automatically. Manager Watchdog will make five attempts to restart the Manager and then, if it has not succeeded, it will exit. Manager Watchdog, by default, is a manual service; you must explicitly start it. Caution 1: You can instead change this setting to be automatic if you wish the service to start automatically after a system reboot. Caution 2: If you have chosen to change the Manager service setting from its default (Auto) to "Manual," (during a troubleshooting session, for example) then consider doing the same for Manager Watchdog. This will prevent the Manager Watchdog from restarting Manager automatically. 81
