Parameter management
Use Parameter management to configure and deploy application parameters across one device or many devices.
Parameter management helps you control application settings without updating each device manually.
Before you start
Confirm that:
your role allows you to manage parameters or run parameter rollouts
you know which application and version the parameters apply to
you have the correct parameter files or template data for the target devices
If you plan to deploy the configuration next, review:
What parameter management supports
Use parameter management to:
define and update application parameter values
manage parameter configuration for one device or many devices
prepare parameter data for rollout
separate frequently used values into basic or advanced parameter sets
Understand application parameters
Applications include executables and configuration files.
The configuration files store application parameters. These values control how the application behaves on the device.
Parameter attributes can be added when an application is introduced. They can also be updated later and downloaded to devices as part of a rollout.
Understand parameter files
Parameter management uses two XML file types:
VPFX — the Verifone Parameter Form file. This file lists the available parameters.
VPDX — the Verifone Parameter Definition file. This file lists the parameters and their configured values.
You configure the parameter values in the .vpdx file. Then upload the definition file to Device Management before scheduling a parameter rollout.
Understand parameter templates
A parameter template is a reusable set of parameter values for an application.
Use templates to:
manage a common configuration for a group of devices
update some or all parameters for an application
reduce repeated manual edits across the estate
One or more parameter templates can be configured for each application.
Basic and advanced parameters
Parameter management supports both basic and advanced parameter files.
Use this split to organize parameters by how often they are configured or reviewed.
You can:
view and edit parameters in the basic list
view and edit parameters in the advanced list
schedule rollouts for either parameter type to one device or a batch of devices
Contact the VCS team to upload a user-defined VPFX file for basic and advanced parameters.
Application-specific VPFX files can be uploaded to Device Management. After upload, only the basic parameters configured for the selected application version are shown in the basic parameter view.
How parameter management fits into rollouts
Parameter management is the preparation stage for parameter deployment.
Most parameter rollout work follows this order:
Define or update the parameter values.
Organize the values in a template or parameter file.
Schedule the rollout.
Monitor rollout progress and results.

Result
Parameter management prepares the configuration values needed for a controlled parameter rollout.
