cx_Oracle module for built-in Python

DawenXie — Tue, 11 Sep 2012 20:19:06 GMT

We used to have ArcGIS for Server 10.0 (Java version) installed. We manually compliled a 32-bit cx_Oracle module for the built-in Python 2.6 and we had some geo processing tools using cx_Oracle to connect to our Oracle Database directly.

Recently We upgraded our server to 10.1 (Linux) and ran into a problem in compling cx_Oracle module for the built-in Phthon 2.7. The difficulties are different than those under 10.0: ArcGIS is now running python under wine.

Anyone has experience on doing similar installation? Any suggestion would be appreciated!

Forgot to provide a followup on this: we got a solution after working with ESRI support for more than a week. I can provide more details if someone runs into the same issue. Contact me through message.

Two software enhancement requests were logged that related to this:

[#NIM085268 Enhance ArcGIS server 10.1 for Linux to better handle GP service based on python script that involves custom modules and database connection client ]

Since I got a few inquiries on this, it would be helpful to post it here.

The trick is to load the cx_Oracle.pyd (from a Windows 7 64-bit machine) and 64-bit Windows Oracle Instant Client's .dll files into a specific folder on the Linux server. It should be the site-packages directory of python27, something like:

/data/ags/arcgis/server/framework/runtime/.wine/drive_c/Python27/ArcGISx6410.1/Lib/site-packages

Below are the files I copied:

This for posting Dawen. This is exactly what we needed to get up and running.

Has anyone out there had luck using cx_Oracle on ArcGIS Server for Linux 10.2+?

We are in the process of upgrading from 10.1 to 10.5 and we can 't seem to get cx_Oracle to connect to our Oracle database. The suggestion above worked on our 10.1 server, but not on 10.5. We put in a ticket with ESRI, but they referenced the following documented bug (documented at 10.2) and said that the cx_Oracle is supported by ArcGIS server for Linux.

NIM096269 - The Python implementation provided with ArcGIS for Server on Linux is unstable when running geoprocessing scripts which leverages the 3rd party cx_Oracle module.

We have a number of geoprocesses that rely heavily on cx_Oracle and I'd like avoid rewriting them.
