CX Oracle will not work with the mac bundled python. Install python with Homebrew.
brew install python3
pip3 install virtualenv
Next install CX_Oracle for python. If it will be used in a virtual env, create that first.
# create virtual env
python3 -m virtualenv venv
# install cx oracle
pip install cx_Oracle
Download Oracle Client basic.
Unzip it into the final directory.
sudo mkdir -p /opt/oracle
Move the unzipped download into that folder.
Add links to the /lib
folder to make cx_oracle
accessible.
mkdir ~/lib
ln -s /opt/oracle/instantclient_12_2/libclntsh.dylib.12.1 ~/lib/
Create the folder for the tnsnames.ora
file.
mkdir -p /opt/oracle/instantclient_12_2/network/admin
