Errore sul collegamento a Oracle da programma py2exe'd: Impossibile acquisire handle di ambiente Oracle

Question

Il mio programma python (Python 2.6) funziona bene quando l'eseguo usando l'interprete Python, si connette al database Oracle (10g XE) senza errori. Tuttavia, quando compilo usando py2exe, la versione eseguibile viene a mancare con "Impossibile acquisire Oracle handle di ambiente" presso la chiamata a cx_Oracle.connect ().

Ho provato quanto segue con nessuna gioia:

• Oracle 10g istante cliente e 11g
• Oracle XE client
• reinstallare cx_Oracle-5.0.2-10g.win32-py2.6.msi
• impostazione ORACLE_HOME così come PATH
• un altro computer con un semplice client Oracle e l'exe
• varie opzioni per la costruzione del exe (nessuna compressione e / o utilizzando file zip)

Il mio TestCase:

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
    )

Risultati:

Answer 1

Lo hai la certezza di escludere l'oci.dll quando hai costruito con py2exe? Se la versione della DLL sulla vostra macchina non è compatibile con la versione del client su un'altra macchina di provarla su (ho notato che si è tentato un client 11g ma 10g sulla vostra macchina), allora questa configurazione non funzionerà (non ricordo il messaggio di errore effettivo però).

Answer 2

build_testora.py riveduta, per riferimento futuro:

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
    )
