Configuring a dynamic cluster with homogeneous nodes to support vertical stacking

You can configure vertical stacking for a dynamic cluster with nodes that have similar computing power by updating settings in the administrative console.

Before you begin

  • Determine the stacking number for your dynamic cluster. For more information, read about this task. If you determine that your application does not have an internal bottleneck when you perform application profiling, do not enable vertical stacking.
避免困難 避免困難: When vertical stacking is enabled, all stacked instances must be started on a given node in order to fully utilize the processing power of that node. If all instances are not started, for instance if the cluster is in manual mode, then it may not be possible to use all of that node's processing power, even if the cluster is being heavily loaded. gotcha

About this task

You can enable vertical stacking when you create the dynamic cluster, or you can modify the settings on an existing dynamic cluster to enable vertical stacking. Perform the following steps to modify the settings on an existing dynamic cluster.

Procedure

  1. In the administrative console, click Servers > Clusters > Dynamic clusters > dynamic_cluster_name.
  2. To enable vertical stacking, click Allow more than one instance to start on the same node.
  3. Enter the number of instances to start on the same node. This value is the stacking number that you calculated.

What to do next

Tune and monitor your application placement configuration.
