cx_Oracle issue

Hi All,

When I try to create a connection to Oracle 10g DB using cx_Oracle library I get the error message: cx_Oracle.DatabaseError: ORA-24315: illegal attribute type


The DB is installed on the same machine I am running the code. Is there anything I am doing wrong or any mistakes in the syntax?? Below is the code for your reference:

F:\MyWork>python
Python 2.6.1 (r261:67517, Dec 4 2008, 16:51:00)
MSC v.15
Type "help", "copyright", "credits" or "license" for more
import cx_Oracle>>> connection_string = "system/[email protected]">>> connection = cx_Oracle.Connection(connection_string)Traceback (most recent call last): File "<stdin>", line 1, in <module>cx_Oracle.DatabaseError: ORA-24315: illegal attribute typeThanks,Abdul

    Works ok in my environment (note I'm using python 2.5).

    -----
    $ ipython
    Python 2.5.2 (r252:60911, Jul 31 2008, 17:28:52)
    Type "copyright", "credits" or "license" for more information.

    In [1]: import cx_Oracle as ora

    In [2]: con_str = "i/[email protected]"

    In [3]: con = ora.connect(con_str)

    In [4]: type(con)
    Out[4]: &lt;type 'cx_Oracle.Connection'&gt;

    In [5]: con = ora.Connection(con_str)

    In [6]: type(con)
    Out[6]: &lt;type 'cx_Oracle.Connection'&gt;
    -----
    Q: what is the output if you do:

    type(connection_string)


    ?

    type(connection)
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    NameError: name 'connection' is not defined

    I asked for connection_string, not connection. Also I'm assuming you're running it in the same python session you run the previous code you show us. Is that right?

    Here is the code.....

    Python 2.6.1 (r261:67517, Dec 4 2008, 16:51:00) [MSC v.1500 32 bit (Intel)] on win32
    Type "help", "copyright", "credits" or "license" for more information.
    import cx_Oracle
    connection_string = "system/[email protected]"
    connection = cx_Oracle.Connection(connection_string)
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    cx_Oracle.DatabaseError: ORA-24315: illegal attribute type
    type(connection_string)
    <type 'str'>
    >>>




    I am doing all this under the same python session.

    Since I was unable to find out what is happening, I forwarded your problem to the cx-oracle-users list. You can find an answer over there. Here's [the link|http://sourceforge.net/mailarchive/forum.php?forum_name=cx-oracle-users&max_rows=25&style=nested&viewmonth=200812&viewday=19].

    I encountered this problem today, and there was no answer on the web.
    This is what I learned, although it is embarassing to admit. I had installed
    the Ora11g version of cx_Oracle, but the database is Ora10g. I deleted
    the Ora11g cx_Oracle files, installed the Ora10g version, and everything
    worked.
