I have a Python script that builds tile packages from a set of .mxds. I created this script last fall, and from the beginning it has always defaulted to using multiple cores (I have a four core machine). The script runs in IDLE. It would always say "Generating tile cache using 4 parallel instances."
Months later and I have to run this script again to generate new tile packages. Now when I run the script it says "Parallel processing has been disabled for the tool on this product." To the best of my knowledge I have not changed my ArcGIS configuration. When I run the same process on the command line in ArcGIS it still says "Generating tile cache using 4 parallel instances."
So somewhere in the process of the script calling arcpy, the parallel processing is being denied. I have half a dozen sets of tiles, and so now what used to take 8 hours is taking over a day.
I've scoured the internet, checked my scripts, checked the licensing for ArcGIS, talked to our network security team about McAfee possibly interfering with it, and I am stumped. I even tried forcing the parallel processing by setting
arcpy.env.parallelProcessingFactor = "100%" but then the script errors out, saying "ExecuteError: ERROR 001493: The tool does not support parallel processing on this product."
I'm running ArcGIS 10.2 and Python 2.7.3 on Win 7 Pro.
Anyone have an idea?
