linux - unixODBC 产生 ORA-12154 TNS 解析错误，而 sqlplus 工作正常

Question

我在设置与 Oracle 11g R1 数据库的 unixODBC 连接时遇到了一个奇怪的错误。一切设置完成后，我想尝试使用 isql 测试连接。它不断返回错误

[08004][unixODBC][Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified

令我困惑的是，我可以使用相同的环境和 TNS 符号通过 sqlplus 进行连接

sqlplus dbuser/password@DBOPBAC9
Copyright (c) 1982, 2011, Oracle.  All rights reserved.

Connected to:
Oracle Database 11g Release 11.2.0.3.0 - 64bit Production

SQL>

我已经处理了两天的问题，但找不到解决方案。 ORA-12154 是一个常见错误，我已经找到了很多可能的解决方案。但他们都不适合我。这是令人沮丧的。

这是我尝试过的:

提到的环境变量都是在启动isql之前设置的

ORACLE_SID=DBOPBAC9
ORACLE_BASE=/CSGPBAC9/DBA/oracle
ORACLE_INSTANT_CLIENT_64=/CSGPBAC9/opt/myuser/tools/instantclient_11_2_x64
ORACLE_HOME=/CSGPBAC9/DBA/oracle/product/11.2.0
TNS_ADMIN=/CSGPBAC9/DBA/oracle/product/11.2.0/network/admin

这是在 $TNS_ADMIN 目录中找到的 tnsnames.ora

DBOPBAC9 =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = host IP)(PORT = 1480))
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = DBOPBAC9)
  )
)

这是sqlnet.ora

TRACE_LEVEL_CLIENT = OFF
SQLNET.EXPIRE_TIME = 10
NAMES.DIRECTORY_PATH = (TNSNAMES)
DIAG_ADR_ENABLED=off

这是我的 unixODBC 设置。我已将 unixODBC 安装到目录 /opt/unixODBC 并相应地设置环境变量。 odbc.ini 位于目录 /opt/myuser/tools/unixODBC 中，并且还设置了变量。

odbc.ini

I have created a strace output检查错误但不幸的是我找不到任何东西。在我看来，它似乎能够找到 tnsnames.ora 文件并读取它

你需要编辑odbc.ini

ServerName = TNS_ALIAS
