Pairing Remote Engines using a dedicated web service

Get the Remote Engine key, a pre-authorization key to be used for pairing, and open a dedicated web service to pair your engines.

This section applies on the following situations:
  • You did not provide the pairing key when installing your engine, so you need to manually get the key to pair your engine with its logical entity in Talend Management Console.
  • You need to re-install your engine.
  • You have run into connection issues between the logical entity in Talend Management Console and the physical entities of the engine.
If you have installed an engine using the installer and already defined the Remote Engine key during the installation process, this pairing is already set up. You can ignore this section.

Before you begin

  • You have installed the Remote Engine.
  • You have created a Remote Engine logical entity in Talend Management Console.

Procedure

  1. Launch the Talend Remote Engine console on your machine ( trun.bat).
  2. Open Talend Management Console.
  3. Open the Processing page then click the Engines tab.
  4. Select the environment of the engine from the Environment drop-down-list.
    You can also use the search box and the filter options to filter the list.
  5. On the engine list, click the remote engine for which you want to reset the pairing.
  6. In the Engine details blade that is displayed, click the Manage tab.
  7. Copy the pairing key.
    The Manage tab displays different information depending on the pairing status of the engine.
    • If the engine is unpaired, copy the key from the Remote Engine key field.

    • If the engine has been paired, but you need to reset the key to pair the engine again for a re-installation or repairing connection issues, do the following:
      1. In the Reset the connection section, click Reset the key to open the corresponding wizard.

      2. On the first window of the wizard, click Reset key.

        This window provides information about how your tasks and plans are affected by resetting the key.

      3. In the second window, copy the new pairing key.

        This pairing key, also referred to as preauthorized key, pre-authorized or pre-authorization key, is used in your Remote Engine configuration to set up the connection to that engine.

  8. Launch http://localhost:8043/configuration.
  9. Paste the key in the corresponding field.
  10. Click Pair Remote Engine.
  11. Type list then press Enter .
    All bundles are in Active status.

Results

Your remote engine has been paired with your account and the status moved to Paired on Talend Management Console.

To run tasks with the Remote Engine as the execution runtime, ensure that you have the Execute right on the workspace where the engine is located.

If you need to know the Java version used by the engine, click the Configuration tab in the Engine details blade. There you can see the version Talend Remote Engine is using for start and also the Java version it uses to run tasks and plans. Note that by default, Talend Remote Engine uses the Java it starts with to run tasks and plans.
