About Integration Appliance States
Integration Appliances in a High Availability (HA) pair can be in one of many states. States for Integration Appliances in an HA pair include:
States for Integration Appliances in an HA pair include:
- ACTIVE_1
- The Active machine cannot communicate with the Standby machine; however, the Active machine continues to process data.
- ACTIVE_2
- The Active machine is successfully processing data and can communicate with the peer HA machine.
- IDLE
- Displays when the Active machine or Standby machine encounters a hardware or software problem. An IDLE state helps to ensure data integrity between an HA pair. IDLE is not always an error state.
- For example, the Active machine enters an IDLE state when it power cycles and remains in this state until it can verify the state of the Standby machine.
- STANDBY
- The Standby machine is successfully synchronizing with the Active machine.
- TRANSITIONING
- Can occur immediately before or after rebooting. Typically, a machine in an HA pair remains in this state after rebooting long enough to perform some initialization, find its peer, and then transition into the appropriate state.
- UNKNOWN
- Occurs when the peer machine is unavailable. For example, when a Standby machine is powered off, the Active machine states that the state of the peer machine (Standby machine) is UNKNOWN.
