Error Loading Python Extension Module for ASE 15,7


It's my first post on this site. I hope I'm posting this question in the right forum.

I'm getting the following error when trying to import sybpydb using python 2.7.3. I've included version information

[sybase@localhost py]$ python

Python 2.7.3 (default, Aug 9 2012, 17:23:57)

[GCC 4.7.1 20120720 (Red Hat 4.7.1-5)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import sybpydb

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

sybpydb.DatabaseError: Error in initializing dbcapi.


[sybase@localhost py]$ echo $PYTHONPATH


[sybase@localhost py]$ echo $LD_LIBRARY_PATH


[sybase@localhost py]$ uname -a

Linux localhost.localdomain 3.8.11-200.fc18.x86_64 #1 SMP Wed May 1 19:44:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

[sybase@localhost py]$ isql -U sa -S ASE01 -w 5000

    You maybe running into a known bug.

    There were issues with python in the inital 15.7 releases.

    CR# 715059 -

    Title - Missing locale file causing error on intialization

    Error - sybpydb.DatabaseError: Error in initializing dbcapi.

    Fixed- 15.7 ESD#5

    You can check your client version by running the command:

    isql -v

    I would suggest using the newer Software Developers Kit(SDK)


    Install SDK 15.7 ESD#7 (lastest release as of 5/20/2013)

    Install Python 2.6.x (will not work with 2.4 or lower, not sure about higher version)
    Once these are installed...
    Go to your SDK install

    source SYBASE.csh

    set the environment variable PATH to run the correct python compiler.
    setenv PATH /usr/u/hansenr/activepython/bin:$PATH


    setenv PYTHONPATH $SYBASE/OCS-15_0/python/python26_64/dll

    edit sql.ini
    add entry for the ASE you wish to connect to.
    ASE must be version 15.7 or higher.


    setenv PYTHONPATH $SYBASE/OCS-15_0/python/python26_64r/lib

    vi $SYBASE/interfaces
    add entry for the ASE you wish to connect to.
    ASE must be version 15.7 or higher.

    master tcp ether solex 2212
    query tcp ether solex 2212


    cd $SYBASE/OCS-15_0/sample/python

    Run the command python to make sure you have the correct version
    ctrl-D out of this after you see the version (ie 2.6.x)

    Edit if you need to login using another login besides sa and blank password.
    You can also edit the command to print another table and so on.

    If everything looks fine run the sample:


    If you are using any security settings, you must enable them in the SDK.

    Example:ldap, kerberos,ssl
