Install cx_Oracle on Oracle Linux 8

Dietmar Uhlig

In Oracle Linux 7 it was easy to install cx_Oracle (see https://yum.oracle.com/oracle-linux-python.html#cx_OracleSystemPython). In Oracle Linux 8 I can't find python-cx_Oracle in the repositories. How to install cx_Oracle when the machine has no internet access but only access to mirrored OL repositories?

Kind regards,

Dietmar

I understand an RPM is planned.

A few people have been asking the Oracle Linux group to release cx_Oracle RPMs.

Assuming your 'no internet access' means no regular access, then you could download a wheel from PyPI https://pypi.org/project/cx-Oracle/#files and install locally. In fact there's a section in the cx_Oracle installation guide for this: https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html#installing-cx-oracle-without-internet-access

Python 3.8.5

Otherwise, building from source, as shown in the installation manual is the other option.

Thanks for your answer. Manual install is always an option but only the second-best. Our IT guys mirror the official OL yum repos into our intranet. All the machines without internet get their regular security updates from these mirrored repositories. This mechanism is trusted. With manual installation of a whl package I'm on my on: checking for security fixes, finding and downloading the most recent version, and copy it to the machines in the intranet. An rpm in an official yum repo is much better: the responsibility for delivering security fixes gets transferred to Oracle. ;-) If Oracle's official answer for providing python-cx_Oracle in the yum repos is "No" than that's it. But I wanted to ask.
