What is cx_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

What's new?

This release has a number of small enhancements intended to build upon the
release of 6.0 made a few months ago. Topping the list is support for
accessing sharded databases, a new feature in Oracle Database 12.2. Support
for creating connections using the SYSBACKUP, SYSDG, SYDKM and SYSRAC roles
was also added, as was support for identifying the id of the transaction
which spawned a subscription message. For those on Windows, improved error
messages were created for when the wrong architecture Oracle Client is in
the PATH environment variable. Improvements were also made to the debugging
infrastructure and a number of bugs were squashed. The test suite has also
been expanded. The full release notes can be read here:
