What is cx_Oracle?

cx_Oracle is a Python extension module that enables access to Oracle
Database for Python 3.x and 2.x and conforms to the Python database API 2.0
specifications with a number of enhancements.

Where do I get it?

The easiest method to install/upgrade cx_Oracle is via pip as in

    python -m pip install cx_Oracle --upgrade

What's new?

This release focused on session pools. Specifically, a session callback may
now be specified when a pool is created. This allows an application to
improve performance by reducing the number of round trips to the database
needed in order to set session state.

A number of smaller enhancements and bug fixes were also made. See the full
release notes for all of the details:
