App standby state active


Minimize standby latency and ensure standby correctness: Standby latency is defined as the time between when a standby is told to become active and when it is actually providing service. “Hot” standby systems are those that actively update internal state in response to active system checkpoints, resulting in millisecond down times. N-to-N — A combination of active/active and N+M clusters, N to N clusters redistribute the services, instances or connections from the failed node among the remaining active nodes, thus eliminating (as with active/active) the need for a 'standby' node, but introducing a need for extra capacity on all active nodes. Aug 04, 2016 · The Active/Standby mode of operation (A/S) evolved from initially having the hardware available and connected into the network, to having the necessary software completely installed and available on the second node as well. This is sometimes referred to as a ‘warm standby’ or ‘warm spare.’ Jul 13, 2016 · The app will simply log out the current state when a Job/Alarm is kicked off, as well as logging when the device has stepped into idle mode. All of the log statements are written to disk so that you can view them in the app if you wish to test your device in real world usage. Otherwise, simply keep track of the log statements in the device log.
