Load Limits

You can enable the automatic distribution of resource group load across nodes by setting load limits. You can configure a set of load limits for each cluster node. You assign load factors to resource groups, and the load factors correspond to the defined load limits of the nodes. Each resource group is started on a node from its node list. The RGM chooses a node that best satisfies the configured load distribution policy. As resource groups are assigned to nodes by the RGM, the resource groups' load factors on each node are summed up to provide a total load. The total load is then compared against that node's load limits.

The default behavior is to distribute resource group load evenly across all the available nodes in the resource group's node list. You can configure load limits in a global cluster or a zone cluster.

For instructions on how to configure load limits using the command line, see How to Configure Load Limits on a Node in Administering an Oracle Solaris Cluster 4.4 Configuration. For instructions on how to configure load limits using the clsetup utility, see Installing and Configuring an Oracle Solaris Cluster 4.4 Environment.
