Hi!,

I’ve created a simple REST api application using Django.  
Oracle 12C is the database server, installed required python package(cx\_Oracle) for database connectivity, application works fine on the Django internal web server i.e on [http://localhost:8000/](http://localhost:8000/). The application is hosted on IIS, I get the following error when accessed through IIS i.e [http://localhost:80](http://localhost:80).  
**Error:** “DPI-1047: Cannot locate a 64-bit Oracle Client library: “The specified module could not be found”. See [https://oracle.github.io/odpi/doc/installation.html#windows](https://oracle.github.io/odpi/doc/installation.html#windows)”

Environment & Version:  
– Created the application under virtual environment  
– Python Version: Python 3.7.3  
– asgiref==3.2.10  
–cx-Oracle==7.3.0  
–Django==3.0.7  
–djangorestframework==3.11.0  
–pytz==2020.1  
–sqlparse==0.3.1  
–wfastcgi==3.0.0

Any help is greatly appreciated.

Since this works using runserver, I’m guessing that it’s unlikely to be a Django issue. My first reaction to this is that it would be an IIS / Python environment issue. You might find more help in an IIS-specific forum, or possibly even StackOverflow.  
(It’s been about 12 years since I’ve configured anything under IIS - I’ve got no useful information to provide.)
