Hi,

I'm using the cx_oracle python module to access an oracle database
It works fine but when I run within a qt environment it fails with the
following error:
ORA-01017: invalid username/password; logon denied

The script that works:

import cx_Oracle as Oracle
import qt
sql_query = "SELECT * FROM AC_DATATYPE"
dbUser = ...
dbPassword = ...
dbHostname = ...
dbInstance = ...
dbPort = ...
dbDSN = Oracle.makedsn(dbHostname, int(dbPort), dbInstance)
#### app = qt.QApplication([])
dbConnection =
Oracle.connect(user=dbUser,password=dbPassword,dsn =dbDSN)

The connection fails if the line
#### app = qt.QApplication([])
is uncommented

- It runs on Linux x86_64, with python 2.4, oracle OCI 9.2,
cx_oracle4.1, qt x11 free 3.3.4
- qt is compiled WITHOUT sql drivers
- This works fine (with the qt call) on another linux x86_64 (with
the whole binariesython,lib oracle,qt, ...)


Any tips ??

thanks

thanks but
Unfortunately, this won't fix since the database connection and the
query must be executed from the Qt graphical user interface, that is
to say after the qt application is launched.
The script I've provided is just a simplify part of a big application,
and this application works fine on windows, solaris and even on some
other linux boxes !

I reply to myself because I've found the problem:
I've replaced NLS_LANG=ENGLISH with NLS_LANG=
