Procedure

  1. In the Menu tree view of Talend Administration Center's home page, expand Conductor.
  2. Click Servers to display the list of the remote execution servers available for deploying and executing tasks.
    Note that you can also display the list of servers in the Metaservlet using the listServer command. For more information about the MetaServlet parameters, see Parameters and actions in metaServlet.
    The figure below illustrates an example of a list of execution server entries.
    There are three types of execution servers, depending on what you want to deploy and execute:
    • Job servers (default). This type of server is used to deploy and execute Jobs tasks only when you subscribed to one of our data-oriented products.
    • Talend Runtime. This type of server can be used to deploy and execute Jobs tasks if these Jobs are linked with Services or Routes, but it is especially used to deploy and execute Services, Routes, or even generic OSGi features when you are using our service-oriented products.
    This list provides the following information for each of the created execution server entries:
