The Logical Clusters folder contains a list of defined logical clusters and a wizard to help you add new logical clusters. The right pane shows the following details:
Cluster ID – displays the associated ID number for each logical cluster.
Current state of the logical cluster – the connection status of the logical cluster, on- or offline.
Connections – the number of active connections in the logical cluster.
Base instances – the number of base instances in the logical cluster.
Active base instances – displays the number of base instances currently active in the logical cluster.
Failover instances – the number of instances that are configured for failover.
Active failover instances – displays the number of active failover instances.
Down routing mode – displays the down-routing configuration. One of:
system – sends unroutable connections to the system logical cluster. system ensures the highest availability as the system logical cluster is always online for every instance. This is the default setting.
open – sends unroutable connections to the open logical cluster. If the connection cannot be sent to the open logical cluster, or the connection does not support redirection, the instance applies the down-routing mode of the open logical cluster.
disconnect – disconnects unroutable connections. This setting can enforce resource reservation by disconnecting clients that cannot be served by instances in the target logical cluster.
Failover mode – displays the failover mode configuration. The options are instance or group.
Start-up mode – displays the start-up mode configuration: automatic (the option is unselected) or manual.
System view – displays the system view configuration, instance or cluster.
Roles – only the system-created logical cluster has the system role. By default, the open role is assigned to the system logical cluster. When the open role is assigned to a new logical cluster, the open role is removed from the logical cluster that previously owned that role.
Load profile – displays the name of the load profile used for the cluster.
