linux - [01000][unixODBC][驱动程序管理器]无法打开 lib '/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so' : file not found

Question

我正在尝试从 Linux 服务器访问 Oracle。我正在使用 unixODBC。

当我尝试使用 isql 访问 oracle 时出现驱动程序管理器无法打开 libsqora.so.12.1 的错误。

odbc.ini

 [Oracle 11g ODBC driver]
 Description=Oracle ODBC driver for Oracle 11g
 Driver=/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so
 FileUsage=1

然后，当我使用 isql 访问 oracle 时，出现以下错误:

 [root@xxxxx lib]# isql -v NAME
 [01000][unixODBC][Driver Manager]Can't open lib '/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so' : file not found
 [ISQL]ERROR: Could not SQLConnect

我在 odbcinst.ini 中有拼写错误。我已更正但仍然是同样的错误。

 [root@xxxxx tmp]# isql -v NAME
 [01000][unixODBC][Driver Manager]Can't open lib '/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so.11.1' : file not found

修复了 LD_LIBRARY_PATH 更新的原始问题，但现在由于我正在尝试使用 32 位 Oracle 客户端，它又被破坏了。

在目录/opt/oraClient/11.2.0.4_32/中安装了 32 位 oracle 客户端。

修改了odbcinst.ini:

[Oracle 11g ODBC driver]
Description=Oracle ODBC driver for Oracle 11g
#Driver=/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so.11.1
Driver=/opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1
FileUsage=1

错误:

[root@xxxxx lib]# /usr/local/bin/isql -v NAME

 [ISQL]ERROR: Could not SQLConnect

如果我需要使用 32 位 Oracle 客户端，我做错了什么......我知道这是环境变量中的东西。

 [root@xxxxx lib]# file /opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1
 /opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped

我启用了跟踪但无法在此处附加文档。我可以发送电子邮件。

更多调试信息:

 [root@xxxxx bin]# ldd /opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1
 ldd: warning: you do not have execution permission for `/opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1'

    /lib/ld-linux.so.2 (0x00134000)

我没有得到可能导致一些问题的“未找到”:

 [root@xxxxx bin]# ls /opt/oraClient/11.2.0.4_32/lib/libclntsh.so.11.1
 /opt/oraClient/11.2.0.4_32/lib/libclntsh.so.11.1

Answer 1

此错误具有误导性:

The file that the error claimed was not present did exist.

我能够通过执行找到实际丢失的文件:

# ldd /path/to/your/socalled/missing/file.so

这返回了一系列文件，其中一个说:

libodbcinst.so.2 => not found

那是我的罪魁祸首。然后我创建了我需要的链接，瞧，错误消失了。
