Node states of the Cluster Mode
| State | Description |
|---|---|
| EXITED | This is a state where MCCS engine is terminated. |
| INITING | This is a state before configuring the heartbeat after starting the engine. This is initial state before both nodes communicate each other through heartbeat network and collect mutual status of node state after MCCS engine is started. This state is normally changed to the LOCAL_BUILD or REMOTE_BUILD state, but if there is a problem with the configuration or physical environment, it remains in the INITING state, or is automatically terminated to the EXITED state. |
| LOCAL_BUILD | When every node in the cluster is in the INITING state, the node with the highest priority at establishing of heartbeat communication is changed to the LOCAL_BUILD state, and the node in this state forms a cluster database from the local configuration file(%MCCS_HOME%\config\main.json). Only one node within the cluster goes through this state to the RUNNING state, and other nodes undergo the REMOTE_BUILD state that receives information from that node. |
| REMOTE_BUILD | When a node in the INITING state detects a node in the RUNNING state through heartbeat communication, it establishes by downloading the configuration. |
| REMOTE_BUILD | This is the state when establishing a configuration database through the LOCAL_BUILD or REMOTE_BUILD is completed, and starts agents and group administrators of all the resources defined at this state. |
| FAULTED | When all the heartbeats with the node in the RUNNING state are disconnected, the node is FAULTED. |
