Applying parameter template to the device

Apply parameter templates to devices in VHQ with options to override or append parameter values for both base-level and multi-record parameters.

Use this when you need to apply a configured parameter template to a specific device.

The parameter template must already be configured in the Application Library. Once created, the Template button activates on the Device Profile screen's Parameters tab.

The package must be assigned to the device before you can apply the parameter template.

Find the device

Search for the device on the Device Search screen using the application name and version, or search by device model in the Download Library screen's Package Name field (the source package name listed in the Application Library for the configured template). You must perform a device search to apply a template.

Apply the template

1

Open the Parameters tab

Select the device, go to Device Profile, then Device Details > Parameters, select the application, and click the Templates icon. Only one template can be applied to a device at a time.

2

Choose override or append

VHQ provides an Override Parameters Value checkbox:

• Selected: Clears all parameters currently applied to the device and replaces them with the template's values. For base-level parameters, only the values in the template are applied; others remain intact. For multi-instance parameters, existing instances are overridden with the template's instances — if a parameter isn't found in an instance, VHQ restores it to the default value.
• Unselected: Retains existing instances and adds any from the template that don't already exist on the device. If an instance exists on both, only that instance is overridden.

3

Apply

Select the template, choose whether to override, and click Apply. VHQ confirms: The parameter values will be overridden. Do you want to continue? Select Yes to apply, or No to cancel.

Example: App1 has base-level parameters P1–P10. Template PT1 defines P1 and P5. Applying PT1 with override copies only P1 and P5 from the template; the rest restore to default values.

Guidelines

• You can edit instances and parameter values directly from the Device Profile screen — click the pencil icon, edit, and Save. The parameters update and activate immediately.
• You cannot edit the parameter template itself from Device Profile — only from Application Library. After editing there, you must reapply the template to see the updated values on the device.
• If the Parameters tab lists no applications, assign a software package first: click Software Assignment on Device Profile, set Assignment type to Package, select the package, and click Save.
• When a template with ADKH4 format is applied (from Device Search or Device Profile), all parameters with source type Template display as User in the UI.
