Parameter Management #
Scenarios
Manage the parameters of compute nodes in the cluster.
Notes
- If modification and reset in parameter operation are grayed out, it indicates that the parameters cannot be modified.
- Parameter adjustment is avilable for all compute nodes.
Procedure
- Login to SphereEx-Console.
- In the upper-left corner of the console, select Cluster > Cluster.
- Select the targeted cluster and click the Parameter button on the right.
- Hover over the question mark in the upper right corner of the parameter to view the detailed explanation of the parameter.
- Parameter list field description:
| Field Name | Description |
|---|---|
| Parameter Name | English only |
| Default Value | Parameter default value (for subsequent reset actions) |
| Current Value | The current value of the parameter is the same as the default value if it is not modified. It is the latest value after modification. |
| Restart Effective | Whether the parameter needs to restart DB Plus Engine-Proxy to take effect (currently, it is limited that the modifiable parameters do not need to be restarted) |
| Parameter Range | Range parameter |
| Operation | Modify parameters and reset parameters. When [Modify] and [Reset] are gray, it means that parameters cannot be modified. |
- Modify parameters.
a. Select a parameter and select Modify in parameter operation to enter the parameter modification dialog box.
b. Fill the parameter modification value into the corresponding position. The lower left corner will remind you whether the parameter needs to restart the compute node to take effect. The restart action currently sahll be completed by the customer.
c. Click OK to finish the modification, and click Cancel to return to the parameter list without any operation.
- Reset parameters.
a. Select a parameter and select Reset in parameter operation to enter the parameter reset dialog box.
b. The lower left corner will remind you whether the parameter needs to restart the compute node to take effect. The restart action currently shall be completed by the customer.
c. Click OK to complete the reset, and click Cancel to return to the parameter list without any operation.
