To change resource weights, perform the following steps.
To display a Resource Groups window, select Resource Groups or [resource group name]>[resource name] from the Resource Group section of the SunPlex Manager navigational frame.
SunPlex Manager displays a task window that prompts for additional information.
SunPlex Manager displays an additional window with the current weights.
To adjust load balancing, enter a new number in the Weight field. When you change a node's weight, the Load Distribution field automatically updates with the new load distribution. This distribution is displayed as a percentage.
Note: The Load Distribution fields will only display values if you enable Javascript in your browser. If Javascript is disabled, the fields will appear empty. |
For an example, see the following table.
Nodes running the resource | Weight by node | Load distribution |
---|---|---|
Node One | 1 | 25% |
Node Two | 1 | 25% |
Node Three | 2 | 50% |
How to Determine Load Distribution
To determine load distribution, divide the node's weight by the total weight
for all nodes. The total
weight for all nodes is determined by adding the weight of all nodes
together.
In this example, Node One's weight is 1 and the total weight is 4. Therefore, Node One's load is 1/4 or 25 percent of the total load.
