errorI'm trying to run a second workspace using python command in "Shutdown Python Script" in the first workspace using the following command. But its giving me an error. Is there anything I need to do different? I am using FME 2012 SP 2

Thanks, Sam

So as suggested by Safe tech support, I created a batch file with the following code:

fme.exe c:\test2.fmw --SourceDataset_ARCGIS_LAYER C:\ScratchParcel\DevEnv.gdb\AddressPoint --DestDataset_SHAPE C:\temp

and added the following code in the shutdown python script window:

import os os.system("C:\\temp\\test.bat")

When I run it, although it says transaction was successful, I don't get any results i.e., the output shapefile is not created.

  • Is there a test2.log in the same folder as test2.fmw? If that's being created when you run the batch file then it's running properly and the workspace itself isn't working correctly.

  • There is no log file being created. So does this mean there is something wrong with the code?

  • Does it work if you run the batch file directly? Run it from a command window or add a pause statement so it doesn't disappear before you can see what it says.

  • I added pause statement to the batch file and there was a tanslation failed message. I uploaded the screen shot of it but it disappeared. Is there any other way to upload the image?

  • Assuming you can run the test2.fmw workspace in workbench, try deleting the --Source/DestDataset params and simply running 'fme.exe c:\test2.fmw'.

Your Python doesn't look syntactically valid. Try

import os
os.system("fme.exe C:\\temp\\test2.fmw --SourceDataset_ARCGIS_LAYER C:\\ScratchParcel\\DevEnv.gdb\\AddressPoint --DestDataset_SHAPE C:\\temp")

I've added the parens and quotes around the string you are passing to os.system, and escaped the backslashes.

Update: In addition, the fme.exe in your path is different than the fme.exe being run by Workbench. Explicitly specify the path to the fme.exe you want to run:

os.system("c:\\pathToFme\\fme.exe test2.fmw")

or, perhaps in this more future proof manner

os.system(os.path.join(os.environ['FME_HOME'], "fme.exe") + " test2.fmw")

which says "run using the fme.exe that we are currently running".

  • Raven, I am still getting error with the python execution.

  • What error do you get? Is it a Python error or an FME error?

  • The logfile says its successful but I dont see any results. "FME_END_PYTHON: evaluating python script from string... FME_END_PYTHON: python script execution complete."

  • There should be a log file left over from the fme.exe execution invoked by your end Python. You can override the log location in the test2.fmw sub-workspace if you are having trouble finding it. (Can be done via command line too, but I can't remember how offhand.)

FME start up and shutdown scripts (FME, Python and Oracle)

only screenshots of the startup/shutdown process so you will have to create your own.

enter image description here

The whole process is a multi-stage system, requiring the use of FME startup and shutdown scripts.
