Create a virtual environment

python -m venv venv

Create an .env file in the root directory of the project

This .env file will be used by the module python-decouple to extract the necessary info to connect to oracle

Here's an example of what the file contents looks like. Ensure that your username and password reflect your own account.

the mydsn variable shouldn't be changed!!!

myuser = "kerekovskik"
mypw = "MYSUPER_SECRET_PASSWORD"
mydsn = "oracle.cise.ufl.edu:1521/orcl"

Activate the virtual environment

Depending on what environment you're working on, you will need to activate the environment differently. Furthermore, Pycharm and VSCODE have their own way of specifying a virtual environment.

• For Powershell

.\venv\Scripts\Activate.ps1

• For CMD

venv\Scripts\activate

Install flask, cx_oracle and python-decouple nto the virtual environment

python -m pip install -r .\requirements.txt

Test your oracle connection

You can easily test whether you can connect to oracle by running the oracleFuncs.py script as a standalone script.

Ensure that you're actually connected to the GatorLink VPN otherwise this will fail.

(venv) PS C:\Users\kkerekovski\db_group_project\DBMSProject> python .\oracleFuncs.py
