I cannot find anything on Google or SO with information on how cx_Oracle works with PyPy. Can someone please tell me if this is possible, and if so, how can I do this?
PyPy actually has its own cx_Oracle module, you need to compile it yourself, although it looks like this:
./pypy/translator/goal/translate.py pypy/translator/goal/targetpypystandalone.py --withmod-oracle
After many hours spent studying various solutions, I decided that only one of them is stable enough: use cx_oracle_on_types: https://github.com/lameiro/cx_oracle_on_ctypes
