If the managed InTouch application is changed and its associated InTouchViewApp instance is deployed, you can select to accept or decline the changes at the run-time node.

A message appears prompting you if you want to accept the changes to the managed InTouch application:

  • When you start WindowViewer from the InTouch Application Manager.

  • While WindowViewer is running.

Depending on the nature of the change, you may be prompted to restart the WindowViewer application, or just reload it. You can also set the behavior of WindowViewer for application changes, such as:

  • How WindowViewer accepts or rejects these changes.

  • How frequently WindowViewer should remind you to reload or restart WindowViewer when changes are pending.

Accept new application versions at the operator node

  • Select Yes. The changes to the managed InTouch application are copied to the operator node and WindowViewer restarts or reloads.

Set the behavior of WindowViewer for application changes

  1. Open the managed InTouch application in WindowMaker.

  2. On the File menu, point to Configure, and then select WindowViewer.

    The WindowViewer configuration screen appears.

  3. Select the Managed Application tab.

  4. In the Change Mode area, configure how WindowViewer responds when changes are deployed. Do any of the following:

    • Select Ignore Changes to have WindowViewer ignore any deployed changes. You can manually configure the RestartWindowViewer() and ReloadWindowViewer() script functions to accept the changes depending on the $ApplicationChanged system tag.

    • Select Restart WindowViewer to have WindowViewer restart automatically.

    • Select Prompt user to restart WindowViewer to have WindowViewer prompt you to restart WindowViewer.

    • Select Load changes into WindowViewer to have WindowViewer load the changes automatically.

    • Select Prompt user to load changes into WindowViewer to have WindowViewer prompt you to load changes into WindowViewer.

      Note: If you select the Load changes into.. or Prompt user to load.. options, WindowViewer must be restarted to recognize changes to a managed application. Even with these options selected, you will be prompted to restart WindowViewer.

  5. In the Reminder Interval (sec) box, type how often, in seconds, the user is reminded to load or restart the changes into WindowViewer. This option is only available when the applicable change mode has been set. Set the interval to 0 to not remind the user again.

  6. Select OK.
