Symptom
The change number of FME Engines dialog doesn't appear on the Engines page in the Web User Interface.
Cause
There are two reasons that this can happen:
1. Initially FME Server was installed as express install, then FME Engines were added to a separate machine, but the database update step was missed in the procedure.
2. The FME Engine machine is reporting to the FME Server Core a hostname that the FME Server Core can not resolve.
Resolution
1. Complete the database configuration step in Adding FME Engines on a Separate Machine.
2. Ensure that the hostname that is received by FME Server Core from the FME Engine machine will resolve to the FME Engine machine. The hostname of the FME Engine machine is specified in the parameter NODE_HOST in the processMonitorConfigEngines.txt file which can be found in the install folder of FME Server, C:\Program Files\FMEServer\Server on Windows or /opt/fmeserver/Server on Linux, on the FME Engine machine.
