Managing a Template

To view a list of the currently defined templates, select the Templates node in the PEM Browser tree control and navigate to the Properties tab.

ARK manage template properties

The Properties tab displays detailed information about the currently defined templates:

  • The Template name column displays the user-friendly name of the template.
  • The Enabled column displays True if the template is available for use.
  • The Engine version column displays the engine identifier.
  • The Server class column displays the server class available to cluster deployed with the template.
  • The Available to column displays the names of the groups/roles/tenants that have access to the template.

You can use options on the template’s context menu to manage the template.

ARK manage template context menu

To access the context menu, right-click on the template name in the PEM Browser tree control. Then, select from the menu options:

Option Action
Refresh Select Refresh to update the definition of the template.
Delete/Drop Select Delete/Drop to delete the template. PEM will confirm that you wish to delete the template before removing it.

Enabling or Disabling a Template

Enabled templates are available for use when provisioning clusters; disabled templates are not available. There are two ways to enable or disable a template - you can:

  • Right-click on the engine name in the PEM browser tree control and select Enable template or Disable template from the context menu.
  • Use the Enabled slider on the template Properties dialog to control the state of the template.

To open the Properties dialog, right-click on the template name and select Properties… from the context menu:

ARK manage enable disable template

Move the Enabled slider to the Yes position to make the template available for cluster provisioning. To disable an template, move the slider to the No position.

Please note that disabling a template has no impact on any running clusters; it simple prevents users from creating new clusters with the template.

Modifying a Template

To modify a template definition, right-click on the template name in the PEM browser tree control, and select Properties… from the context menu. The template definition dialog will open, allowing you to modify the template properties. Please note that you cannot modify the Template ID field; the Template ID is a system-assigned identifier.

ARK manage template modification options

After modifying the template definition, click Save to preserve your changes and close the dialog.

Deleting a Template

To delete a template, right-click on the template name in the PEM browser tree control, and select Delete/Drop from the context menu. The PEM server will prompt you to confirm that you wish to delete the template before the template is deleted.
