These options appear in the General tab:
System view – determines how the logical cluster users view Cluster Edition, whether as an entire cluster, or as individual instances. This affects some queries and stored procedures. Select Instance or Cluster.
Automatically starts logical cluster – select this option if you want this logical cluster to start when the cluster starts.
Failover mode – determines whether the logical cluster fails over to another instance or a group:
Instance – the logical cluster to fail over one instance at a time.
Group – specifies that base instances are replaced only when all base instances fail, and that all failover instances then come online. For example, the failover mode for SalesLC is “group.” If base instance “ase1” fails, the cluster continues to run on base instance “ase2”. No failover instances are brought online. However, if both “ase1” and “ase2” fail, then the cluster runs on failover instances “ase3” and “ase4”.
Fail-to-any – permits the logical cluster to fail over even though no failover instances are available. The logical cluster fails over to any available physical instances in the cluster, based on load.
Fail-to-any configures the logical cluster to fail over to any available instance, even if it is not defined as a failover instance within that logical cluster.
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.
Logical cluster roles – the system role is automatically set to the “system logical cluster.” You cannot change this setting.
By default, the open role is assigned to the system logical cluster. You cannot grant the open role, and it is removed only if another logical cluster assumes that role.
