Adding FME Engines on a Separate Machine

You can add processing capacity to your FME Server by installing additional FME Engines on a separate computer from the FME Server Core.

In the instructions below, the computer that hosts the FME Server Core is the <coreHost>. In a fault-tolerant setup in which FME Server Cores are installed on two separate machines, the machine that you identify as the primary host (not the failover host) is the <coreHost>. Any machine that hosts FME Engines is the <engineHost>.

Note: In a fault-tolerance environment, we recommend assigning unique names to FME Engines. However, if multiple FME Engine hosts have the same FME Engine name, the job queue server configuration applies to all FME Engines with the same name in the same way regardless of which host it resides on. For more information, see Job Queues.

ClosedWindows
  1. Obtain the Installer. Be sure to obtain the FME Server Installer (not the Engine Installer).
  2. Start the installer on another computer (<engineHost>).
  3. On the Choose Setup Type dialog, select the Engine setup type.
  4. On the Destination Folder dialog, specify the directory to install the FME Engines.
  5. On the Existing FME Server System Share dialog, provide the UNC path to the System Share directory. (In most cases, the directory is the same as the <coreHost> System Share directory.)

  6. On the FME Server Hostname dialog, enter the hostname of the <coreHost> computer. In a fault-tolerant installation, the primary <coreHost> should always be specified. Do not specify the failover host.

  7. On the Database Server Type dialog, specify the database type that you specified when installing the FME Server Core. If you specified a database other than the "FME Server Database," enter the connection parameters in the next dialog.
  8. Complete the remaining dialogs of the FME Server Installer.
  9. If this <engineHost> is connecting to a <coreHost> that also hosts the built-in FME Server database and the initial FME engines, as with an Express Installation, allow the necessary connection to this machine:
    1. On the <coreHost>, open file pg_hba.conf, located in %ALLUSERSPROFILE%\Safe Software\FME Server\pgsql\data.

      2. Note: Unless modified, C:\ProgramData is the default value of the %ALLUSERSPROFILE% environment variable.

    2. Change the following lines:

      3. host    all     all     127.0.0.1/32      md5

      host    all     all     ::1/128         md5

      to:

      host    all      all       0.0.0.0/0         md5

      host   all      all     ::/0             md5

    3. Restart the FME Server Database and FME Server Engines services.
  10. If the <coreHost> machine was an Express Installation of FME Server, complete the following steps on the <coreHost> to configure the FME Server Web Services:
    1. Open the corresponding propertiesFile.properties file for the Data Download, Data Streaming, Job Submitter, and Notification services, located at <FMEServerDir>\Utilities\tomcat\webapps\<service_name>\WEB-INF\conf\propertiesFile.properties.

      2. For example, the properties file for the Data Download Service is at <FMEServerDir>\Utilities\tomcat\webapps\fmedatadownload\WEB-INF\conf\propertiesFile.properties

    2. For each properties file, locate the parameter REQUEST_DATA_DIR and change the value from a local file system path (for example, C:/ProgramData/Safe Software/FME Server//resources/system/temp/requestdata) to a UNC path that references the <coreHost> (for example, //MyHost/FME Server/resources/system/temp/requestdata).

      3. Note: Use forward slashes only.

    3. After saving the changes in the properties file for each service, restart the FME Server Application Server service.
  11. Ensure that the user account that runs <engineHost> has the necessary permissions to access the FME Server System Share and the FME Server install directory. For more information, see Directory and Account Permissions.
  12. On the <coreHost> machine, open configuration file fmeServerConfig.txt, located in <FMEServerDir>\Server\, and update the FME_SERVER_HOST_NAME parameter to a value that fully resolves to the IP address of the <coreHost> machine.
  13. Restart the FME Server Core service.
ClosedLinux

  1. Mount the FME Server Core installation directory shared by <coreHost>:

    mount <coreHost>:<FMEServerDir>/home/FMEServer

  2. Obtain the Installer. Be sure to obtain the FME Server Installer (not the Engine Installer).
  3. Start the FME Server Installer.
  4. Select the Engine Install.

  5. Choose to install only the FME Engine component by selecting Yes to the FME Engine component prompt and No to the other component prompts.

    The installer prompts you for the path to the <coreHost> installation directory. In a fault-tolerant installation, the primary <coreHost> should always be specified. Do not specify the failover host.

  6. Enter the path to the mounted directory.

    The installer prompts you for the name of the FME Server Host.

  7. Enter the host name of the <coreHost> computer.
  8. Enter the database type you specified when installing the FME Server Core. If you specified a database other than the "FME Server Database", enter the connection parameters.
  9. Complete the remaining dialogs of the FME Server Installer.
  10. Manually start FME Server, and configure it to start automatically.

  11. If this <engineHost> is connecting to a <coreHost> that also hosts the built-in FME Server database and the initial FME engines, as with an Express Installation, allow the necessary connection to this machine:

    1. On the <coreHost>, open file pg_hba.conf, located in <FMEServerDir>\Utilities\pgsql\data\.
    2. Change the following lines:

      3. host    all     all     127.0.0.1/32      md5

      host    all     all     ::1/128         md5

      to:

      host    all      all       0.0.0.0/0         md5

      host   all      all     ::/0             md5

    3. Restart the FME Server Database and FME Server Engines services.

  12. Ensure that the user account that runs <engineHost> has the necessary permissions to access the FME Server System Share and the FME Server install directory. For more information, see Directory and Account Permissions.

  13. On the <coreHost> machine, open configuration file fmeServerConfig.txt, located in <FMEServerDir>\Server\, and update the FME_SERVER_HOST_NAME parameter to a value that fully resolves to the IP address of the <coreHost> machine.
  14. Restart the FME Server Core service.
ClosedVerify the Installation

The installation on <engineHost> starts two FME Engines by default. The FME Engines start and register with the FME Server Core running on <coreHost>. All licensed engines are listed on the Engines & Licensing page of the Web User Interface, under 'Licensed Engines'.

Note: You may have to disable any firewalls that are running on this computer.

You can also use the Engines & Licensing page to perform the following tasks:
