I run nightly updates on many datasets and have completed dissolves for a few years and they used to work just fine. Now, for some reason I cannot get any of the dissolve models to work when triggered from the python script. The models work when I run them manually through ArcCatalog, but I need them to work through the python script every night as opposed to having to run them manually every morning.
I have added a Repair Geometry tool into the model to take care of any issues there, but I still get the invalid topology error (but I only get this error when it runs through Python). I have exported the model into a python script and copied and pasted that into the nightly update python script, and that didn't help either. I have tried many options like creating new models, creating new geodatabases or shapefiles and it still will not work through the python script.
This seems to have started after I tried to run a dissolve on a rather large dataset which took over two week to process in ArcMap and it still hadn't completed when I cancelled the process. Ever since then, any models including a dissolve command have not work through python. I have rebooted my computer several times, and it is still a problem.
I am using ArcGIS 10.2.1 (I cannot upgrade easily because I do not have admin rights) on Windows 7.
If anyone has any ideas or suggestions of what I can do to get the dissolve to work again, I would greatly appreciate it. Because I do not have admin rights, I am limited as to what I can try without having to put in a request to our IT department (which can be a long, painful, and frustrating process).
Thanks in advance for any assistance.
