Error en la conexión con Oracle desde py2exe'd programa: No se puede adquirir de contexto del entorno de Oracle
Pregunta
Mi programa pitón (Python 2.6) funciona bien cuando lo ejecuto con el intérprete de Python, se conecta a la base de datos de Oracle (10g XE) sin error. Sin embargo, cuando compilo usando py2exe, la versión ejecutable falla con "No se puede adquirir de contexto del entorno de Oracle" en la llamada a cx_Oracle.connect ().
He intentado lo siguiente sin alegría:
- Oracle 10g instantánea cliente y 11g
- Oracle XE cliente
- reinstalar cx_Oracle-5.0.2-10g.win32-py2.6.msi
- establecer
ORACLE_HOME
, así como PATH - otro ordenador con un simple cliente de Oracle y el exe
- varias opciones para construir el exe (sin compresión y / o el uso de archivos zip)
Mi caso de prueba:
testora.py:
import cx_Oracle
import decimal # needed for py2exe to compile this correctly
def testora():
"""testora
>>> testora.testora()
<cx_Oracle.Connection to scott@localhost:1521/orcl>
X
"""
orcl = cx_Oracle.connect('scott/tiger@localhost:1521/orcl')
print orcl
curs = orcl.cursor()
result = curs.execute('SELECT * FROM DUAL')
for (dummy,) in result:
print dummy
if __name__ == '__main__':
testora()
build_testora.py:
from distutils.core import setup
import py2exe, sys
sys.argv.append('py2exe')
setup(
options = {'py2exe': {
'bundle_files': 2,
'compressed': True
}},
console = [{'script': "testora.py"}],
zipfile = None
)
Resultados:

cx_Oracle.InterfaceError: Unable to acquire Oracle environment handle
Solución
¿Se asegura de excluir la OCI.dll cuando se construyó con py2exe? Si la versión de la DLL en el equipo es incompatible con la versión del cliente en otra máquina de probarla en (Noté que ha intentado un cliente 11g pero 10g en su máquina), a continuación, esta configuración no va a funcionar (no recuerdo el mensaje de error real sin embargo).
