Oracle'a py2exe'd programından bağlanma hatası: Oracle ortam tanıtıcısı alınamadı

Question

Python yorumlayıcısını kullanarak çalıştırdığım python programım (Python 2.6) düzgün çalışıyor, Oracle veritabanına (10g XE) hatasız bağlanıyor . Ancak, py2exe kullanarak derlediğimizde, çalıştırılabilir sürümü cx_Oracle.connect() çağrısında "Oracle ortam tanıtıcısı alınamıyor" ile başarısız oluyor.

hiçbir sevinçle aşağıdaki denedim:

• Oracle anlık istemci 10g ve 11g
• Oracle XE Client
• cx_Oracle-5.0.2-10g.win32-py2.6 yeniden yükleyin. msi
• PATH yanı sıra ORACLE_HOME ayarı
• yapım makine için sadece Oracle müşterinin exe
• çeşitli seçeneklerle başka bir bilgisayar exe (hayır sıkıştırma ve/veya kullanarak zip dosyasını) ng

Benim dizge:

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 
    )

Answer 1

Py2exe ile oluşturduğunuzda OCI.dll'yi hariç tuttuğunuzdan emin misiniz? Makinenizdeki DLL sürümü, üzerinde çalıştığınız başka bir makinedeki istemci sürümüyle uyumsuzsa, (makinenizde bir 11g istemcisi ancak 10g denediğinizi fark ettim), bu yapılandırma çalışmayacaktır (gerçek hata iletisini unutuyorum) gerçi). İleride başvurmak için

Answer 2

Revize build_testora.py:

from distutils.core import setup 
import py2exe, sys 

sys.argv.append('py2exe') 

setup(
    options = {'py2exe': { 
     'bundle_files': 2, 
     'compressed': True, 
     'dll_excludes': ["oci.dll"] 
     }}, 
    console = [{'script': "testora.py"}], 
    zipfile = None 
    )
