Jupyter Notebook is an open source web application for Machine Learning and Data Exploration.

In this post I will show you how to connect a Jupyter Notebook to Oracle Autonomous Database and explore the data using Python.

The assumption is we already have a Jupyter notebook sandbox running on Oracle Cloud compute instance.

Prerequisites:

I recently had a requirement where the Common User in a Multitenant DB environment wanted to access application tables across Pluggable Databases (PDBs) but at the same time access dictionary views across all PDBs without the need to manually switch between containers. 

This was because I had to setup a monitoring user account to monitor all PDBs performance as well as application workload.

In this example I will show you how the Common User (created at CDB level) can be configured to access the application tables (create at PDB level)
