我已下载，构建和配置
unixODBC-2.3.2.tar
我安装了：
oracle-instantclient12.1-odbc-12.1.0.2.0-1.x86_64.rpm
oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
oracle-instantclient12.1-sqlplus-12.1.0.2.0-1.x86_64.rpm
我按如下方式配置了/usr/local/etc/odbcinst.ini：
[Oracle]
Description = Oracle ODBC Connection
Driver = /usr/lib/oracle/12.1/client64/lib/libsqora.so.12.1
Setup =
FileUsage =
libsqora.so.12.1文件存在：
file /usr/lib/oracle/12.1/client64/lib/libsqora.so.12.1
/usr/lib/oracle/12.1/client64/lib/libsqora.so.12.1: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped
我还配置了odbc.ini文件：
[prd_db]
Driver=Oracle
Description=prod database
Trace=Yes
ServerName=//prddb01:1521/dbp01_svc1
当我使用prd_db credentilas使用isql进行连接时：
isql prd_db
我收到连接错误。用户名和密码准确无误，我可以使用sql developer连接。
我错过了什么？我需要在linux服务器上配置odbc连接。ldd /usr/lib/oracle/12.1/client64/lib/libsqora.so.12.1
