python - django pyodbc アプリケーションを apache に移行する際の odbc 接続エラー

Question

次の修正を試みました: https://code.google.com/p/pyodbc/issues/detail?id=214

それでも同じエラーが発生します。

この状況をどのように改善できるかについてのアイデアはありますか?

# Dynamic Shared Object (DSO) Support

# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.

# Example:
# LoadModule foo_module modules/mod_foo.so

Apache ユーザーは「システム」ユーザーであり、ユーザー DSN ではなくシステム DSN を参照するため、DSN をシステム DSN として設定する必要があります。

pyodbc のこの接続文字列は、私にとってはうまくいきます。

conexion_str = 'SYSTEM=%s;db2:DSN=%s;UID=%s;PWD=%s;DRIVER=%s;' % (self._SYSTEM, self._DSN, self._UID, self._PWD, self._DRIVER)
cnn = pyodbc.connect(conexion_str)
