Logical Cluster Properties

Use the Properties window to view logical cluster information.

Click the Name field of the logical cluster, then click the drop-down arrow and select Properties.

View cluster information such as:
  • System view – whether you view the logical cluster as an entire cluster, or as individual instances.
  • Automatically start logical cluster – whether to start the logical cluster when the cluster starts.
  • Failover mode – whether instances are brought online as a group or individually.
  • Fail to any – whether any instance, or only a specific instance, can be a failover resource.
  • Down routing mode – how client connections are routed if the logical cluster designated by the routing rule is unavailable.
    • system – sends unroutable connections to the system logical cluster.
    • open – sends unroutable connections to the open logical cluster.
    • disconnect – disconnects unroutable connections.
  • Login distribution mode – how connections are distributed in logical clusters with multiple instances. The login distribution mode does not affect single-instance logical clusters.
    • affinity – the instances accepting a connection retains it as long as the target logical cluster is running on that instance. If the load profile specifies a load threshold, and the load on the instance is too high, the workload manager redirects the connection to the least-loaded instance in a logical cluster. If the target logical cluster is not running on the instance, the workload manager redirects the connection to the least-loaded instance in a logical cluster.
    • round-robin – incoming connections are distributed in a round-robin fashion among the instances hosting a logical cluster. For example, if “SalesLC” is running on “ase1” and “ase2”, the workload manager sends the first connection to “ase1,” the next to “ase2”, and so on. Load scores are not included in the algorithm.
  • Logical cluster roles – whether this logical cluster assumes an open role, meaning that all connections that are not routed to a logical cluster via an explicit routing rule are routed to the current open logical cluster. When you create a new cluster, the system logical cluster is automatically designated the open logical cluster. You can reassign the open role to another logical cluster. However, only one open logical cluster can exist per physical cluster.
Base Instances

Base instance names, their identification numbers, and their current state.

Failover Instances

Failover instance names, their identification numbers, their current state, and the failover to which they belong.


Routing applications, logins, and aliases that are associated with the logical cluster.

Load Profile The load profile assigned to the logical cluster or view the current load profile information such as:
  • Metric weights assigned to the selected load profile
  • Minimum load score
  • Login redirection
  • Dynamic connection migration
