A cluster consists of a group of appservers. If one of the appservers fails, requests are routed to other members of the cluster.
To define a new cluster, click New to start the Create a new cluster wizard.
- Name
-
Logical name for the cluster. The name must be unique among clusters within the containing cell.
- Status
-
This field indicates whether the cluster is partially started, started, partially stopped, stopped, or unavailable. If the status is unavailable, the node agent is not running in that node and restart the node agent before we can start the server.
After you click Start or Ripplestart to start a cluster, each server that is a member of that cluster launches if it is not already running. When the first member launches, the state changes to partially started. The state remains partially started until all cluster members are running. When all cluster members are running, the state changes to running and the status changes to started. Similarly, when you click Stop or ImmediateStop to stop a cluster, the state changes to partially stopped when the first member stops, and then changes to stopped when all cluster members are not running.
