FME Server Starts 2 Engines by Default

Symptom

  • You may see 2 FME Engines running when viewing the Web UI Engines page when you only want 1 running.
  • Alternatively, you may see only one FME Engine running, but the log files will show failed attempts to start a second. This can be safely ignored. However, if you have System Events set up this may cause unwanted notifications.

Cause

By default FME Server attempts to start 2 FME Engines.

Resolution 1

The following instructions show you how to change the number of FME Engines that are running on your system.

You can configure FME to start the number of engines you want from the Engines page in the FME Server Web Interface. 
From this page, simply change the number of engines from the default value of 2 to the number you want. If this does not work, try changing it to 0 before setting the correct number of engines.

Resolution 2

If resolution 1 does not work for you, you can configure FME to start the number of engines you want by editing the processMonitorConfigEngines.txt.

You should have an FME Engine license available for each engine you configure to start.

Near the end of the file you will see blocks of text intended for starting FME Engines. By default the lines for starting FME Engines 1 and 2 are uncommented and look like this:

# Start FME Engine 1
START_ENGINE_{SAFE{nodeName}}_Engine1=!TEMPLATE_START_ENGINE! -ENGINE_TYPE {SAFE{engineType}}
 
# Start FME Engine 2
START_ENGINE_{SAFE{nodeName}}_Engine2=!TEMPLATE_START_ENGINE! -ENGINE_TYPE {SAFE{engineType}}

 


To start only one FME Engine comment out the line for Engine 2 so the config file now looks like this:

# Start FME Engine 1
START_ENGINE_{SAFE{nodeName}}_Engine1=!TEMPLATE_START_ENGINE! -ENGINE_TYPE {SAFE{engineType}}
 
# Start FME Engine 2
# START_ENGINE_{SAFE{nodeName}}_Engine2=!TEMPLATE_START_ENGINE! -ENGINE_TYPE {SAFE{engineType}}
