尝试执行NetezzaSQL odbc vi aunixODBC

Question

我正在尝试使用pyodbc执行Netezza连接，大概是RedHat 7盒上的unixODBC。

我无法这样做。

我正常地在/usr/local/nz上加载了netezza。尝试打开连接时。

这是连接字符串：

Connection=Driver={NetezzaSQL};servername=DEVDBSERVER01;port=5480;database=DEV;username=<<USER>>;password=<<PASSWORD>>

odbcinst.ini的内容：

[NetezzaSQL]
Driver           = /usr/local/nz/lib/libnzsqlodbc3.so
Setup            = /usr/local/nz/lib/libnzsqlodbc3.so
APILevel         = 1
ConnectFunctions = YYN
Description      = IBM Netezza ODBC driver
DriverODBCVer    = 03.51
DebugLogging     = false
LogPath          = /tmp
UnicodeTranslationOption = utf8
CharacterTranslationOption = all
PreFetch         = 256
Socket           = 16384

错误是我不了解的东西：

pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/usr/local/nz/lib/libnzsqlodbc3.so' : file not found (0) (SQLDriverConnect)")
Exception ignored in: <bound method dbapi.__del__ of <modules.database.dbapi object at 0x7f6a31b08e80>>

如果我将文件/usr/local/nz/lib/libnzsqlodbc3.so放在提示符下，然后按回车键，则发现没有问题。

我在这里想念什么？谢谢！

相同答复：

[[unixODBC][Driver Manager]Can't open lib '/usr/local/nz/lib64/libnzodbc.so' : file not found]

Answer 1

libcom_err.so.2 => not found可能是问题的原因。

作为解决方法，请尝试从nz目录（驱动程序或工具包）复制该lib到/ lib。另外，您可以尝试安装32位libcom_err软件包。

# rpm -qf /lib/libcom_err.so.2
libcom_err-1.41.12-24.el6.i686

当我在64位系统上安装32位客户端时，我可以复制类似的内容。当我切换到64个客户端库时，它开始工作。
