Configuring Read Weights¶
If one DDM instance is associated with multiple data nodes, you can synchronize read weight settings of the first data node to other data nodes.
Prerequisites¶
You have logged in to the DDM console.
Precautions¶
The read weight can be 0 to 100.
Procedure¶
In the instance list, locate the DDM instance whose data nodes you want to configure read weights for.
Click the instance name to enter the Basic Information page.
In the navigation pane, choose Data Nodes.
Set read weights for associated instances.
Set read weights for multiple instances.
If you want to set read weights for multiple instances at a time, click Configure Read Weight on the Data Nodes page.
In the displayed dialog box, click Synchronize to apply the read weight of the first instance to other instances. This operation requires that read weights of all instances should be the same. Otherwise, you need to manually configure a read weight for each instance.
Set a read weight for an instance.
If you want to set the read weight of an instance, locate the target instance and click Configure Read Weight in the Operation column.
Click Yes.
After the read weight is configured successfully, you can view the updated read weight on the Data Nodes page.
