mxODBC Connect is a commercial client-server product that allows connecting Python to ODBC compatible databases running on remote servers without requiring an ODBC driver on the client side. The product uses mxODBC on the server side and provides a highly portable Python library for the client side. As such it supports all database backend that mxODBC supports, but allows connecting to these from many different Python-supported platforms.

mxODBC Connect supports asynchronous query execution via the popular gevent package, provides secure certificate based authentication, SSL encrypted database connections, comes with full support for stored procedures, multiple result sets, Unicode, a common interface on all platforms and implements many other useful features.

mxODBC Connect Server is compatible with the Oracle Instant Client ODBC drivers.

==== Comments ====

While trying to install the cx_Oracle Python utility, I encounter the following error:

 

sh-2.05b# python setup.py build

running build

running build_ext

building 'cx_Oracle' extension

gcc -pthread -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I/devtools/oracle/product/8.1.5/rdbms/demo -I/devtools/oracle/product/8.1.5/rdbms/public -I/devtools/oracle/product/8.1.5/network/public -I/usr/local/python2.4/include/python2.4 -c cx_Oracle.c -o build/temp.linux-i686-2.4/cx_Oracle.o -DBUILD_TIME="January 21, 2005 11:19:47"

cx_Oracle.c:10: xa.h: No such file or directory

error: command 'gcc' failed with exit status 1

 

Where can I find the xa.h file?  The only package I could find online that provides any such file is a cd i/o library, and that doesn’t seem right.

I am running a 2.4 linux kernel, trying to install cx_Oracle-4.0.1 on top of Python 2.4.

I have tried the beta package which should be more 2.4 compatible, but still no luck.  Any help is appreciated.  Thanks!
