خطأ في الاتصال بأوراكل من برنامج Py2exe'd: غير قادر على الحصول على مقبض بيئة أوراكل

Question

يعمل برنامج Python الخاص بي (Python 2.6) بشكل جيد عندما أقوم بتشغيله باستخدام مترجم Python، فإنه يتصل بقاعدة بيانات Oracle (10G XE) دون خطأ. ومع ذلك، عندما تقوم بتجميعها باستخدام PY2EXE، فشل النسخة القابلة للتنفيذ مع "غير قادر على الحصول على مقبض بيئة Oracle" عند الاتصال إلى cx_oracle.connect ().

لقد جربت ما يلي بدون فرحة:

• عميل Oracle Instant 10G و 11G
• Oracle XE Client.
• أعد تثبيت cx_oracle-5.0.2-10g.win32-py2.6.msi
• ضبط ORACLE_HOME وكذلك المسار
• كمبيوتر آخر مع مجرد عميل أوراكل والإكس
• خيارات مختلفة لبناء EXE (بدون ضغط و / أو استخدام ملف zip)

اختبار بلدي:

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
    )

نتائج:

Answer 1

هل تأكد من استبعاد OCI.DLL عند بنيت مع Py2exe؟ إذا كان إصدار DLL الموجود على جهازك غير متوافق مع إصدار العميل على جهاز آخر تقوم باختباره عليه (لاحظت أنك جربت عميل 11G ولكن 10G على جهازك)، فلن يعمل هذا التكوين (نسيت رسالة الخطأ الفعلية على أية حال).
