Errore nel collegamento a Oracle dal programma py2exe: impossibile acquisire l'handle di ambiente Oracle

Question

Il mio programma python (Python 2.6) funziona correttamente quando lo eseguo utilizzando l'interprete Python, si collega al database Oracle (10g XE) senza errori . Tuttavia, quando lo compilo usando py2exe, la versione eseguibile fallisce con "Impossibile acquisire l'handle di ambiente Oracle" alla chiamata a cx_Oracle.connect().

Ho provato quanto segue con nessuna gioia:

• Oracle Instant client 10g 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 solo un client Oracle e l'exe
• varie opzioni per buildi ng l'exe (nessuna compressione e/o utilizzando il file zip)

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

Hai fatto in modo di escludere OCI.dll quando hai costruito con py2exe? Se la versione della DLL sulla tua macchina non è compatibile con la versione client su un'altra macchina, la collaudi (ho notato che hai provato un client 11g ma 10g sulla tua macchina), quindi questa configurazione non funzionerà (ho dimenticato il messaggio di errore effettivo anche se).

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 
    )
