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.
Avoid trouble: 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
- In the administrative console, click .
- To enable vertical stacking, click Allow more
than one instance to start on the same node.
- 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.
