Synchronization

From ThinManager Knowledge Base

Multiple ThinManager Servers should be synchronized so that a terminal will receive the same configuration regardless of the ThinManager Server that it boots from. ThinManager supports two different methods of synchronization: Manual and Automatic, both of which will be covered in this article.

Automatic Synchronization

Automatic synchronization makes it easier to keep the configuration on the two ThinManager Servers the same. Changing a configuration on one will make the change on the other.
Automatic Synchronization has a few things to consider:

  • It is a good idea to backup the configuration before making changes because a mistake on one ThinManager Server will pass the mistake to the other ThinManager Server. The backup will allow a chance to restore the configuration to a known good state.
    • Select Manage > Backup Configuration from the ThinManager menu bar to backup the configuration.
  • ThinManager has a scheduling function that can be set to automatically back up the configuration.
  • Automatic synchronization is required for Mirrored Redundancy.
  • Automatic synchronization will configure each thin client to send the green/red status lights to both ThinManager Servers so the ThinManager Server Monitor List page isn't shown in the Terminal Configuration Wizard, as it isn’t needed.

Note: Automatic synchronization is required for Mirrored licenses, Redundant licenses, and Enterprise Server licenses


Automatic synchronization is configured in the ThinManager Server List Wizard. Launch it by selecting Manage > ThinManager Server List ThinManager menu.
Proceed the Auto-synchronization Selection page.

Select the Automatic Synchronization checkbox and select the Next button to configure Auto-synchronization.

  • Enter the name of the ThinManager Server in the ThinManager Server field.
  • Enter the IP address of the ThinManager Server. The Discover button will enter the IP address for you.
  • Select the OK button to accept the settings or the Cancel button to close without saving.

Select Finish to accept the changes and close the ThinManager Server List wizard. The two ThinManagers will now be synchronized.

The synchronization status can be checked on the Synchronization tab of ThinManager.

Manual Synchronization

Redundant ThinManager Servers should be synchronized so that the same configuration is available to ThinManager Ready thin clients regardless of where they boot. Automatic Synchronization is the preferred method but the ThinManager Servers can be manually synchronized.
Select Manage > Synchronize Configurations from the menu to initiate the Manual Synchronization. This will launch the Synchronize ThinManager Server Configurations Wizard.

Highlight the primary ThinManager Server as the Configuration Source ThinManager Server and the secondary ThinManager Server as the Configuration Destination. Select Next to proceed. Although many ThinManager Servers can be defined in the ThinManager Server List it is normal to have just a primary and a backup ThinManager Server.

The ThinManager Synchronization Wizard will list the files being updated, including the firmware, TermCap database, modules, and the configuration. It synchronizes everything but the licenses.


Note: The Synchronization tool does not compare and contrast then make changes back and forth. Synchronization will take the files and configuration from the source ThinManager Server and overwrite the corresponding files on the destination ThinManager Server.


Select Next to continue.
