Question

我需要在RHEL 6上设置Oracle ODBC驱动程序以连接到驻留在远程Windows机器上的Oracle数据源。

我采取了以下步骤：
[1]安装oracle-instanceclient-basic
[2]设置环境变量：ORACLE_HOME和LD路径
[3]创建了/etc/oracle/TNSnames.ora并进行了配置，但没有正确设置

最初，我收到错误"Connect failed because target or object does not exist"

然后，我在TNSnames.ora文件中设置了ORACLE_SID = DB_NAME。

但是，这并没有解决问题，我现在收到了一条新的错误消息："TNS: net service name is incorrectly specified"

yum install unixODBC
rpm -ivh oracle-instantclient-basic-10.2.0.3-1.i386.rpm #downloaded on http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxsoft.html
unzip instantclient-odbc-linux32-10.2.0.3-20061115.zip #downloaded on http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxsoft.html
cp ./instantclient_10_2/libsqora.so.10.1 /usr/lib/oracle/10.2.0.3/client/lib/
export ORACLE_HOME=/usr/lib/oracle/10.2.0.3/client
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

此外，您需要设置$TWO_TASK（Oracle希望获取服务器的默认位置）以指向Oracle服务器在Windows上运行的位置 - 不要忘记在最后添加侦听器端口号：

export TWO_TASK=//213.123.23.19:1521/listener

要获取侦听器的名称，请在运行Oracle服务器的Windows提示符下键入以下命令：

lsnrctl
status

它将获得监听器及其状态（READY或UNKNOWN）。连接到处于就绪状态的侦听器：Instance "zelistener", status READY

mkdir / etc / oracle

vi /etc/oracle/tnsnames.ora

MY_SID =
 ( DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS =
  (PROTOCOL = TCP)
  (Host = 127.0.0.1)
  (Port = 1521)
  )
 )
 (CONNECT_DATA = (SID = MY_SID)
 )
)

导出TNS_ADMIN = / etc / oracle

vi /etc/odbcinst.ini

[OracleODBC-10g]
Description = Oracle ODBC driver for Oracle 10g
Driver = /usr/lib/oracle/10.2.0.3/client/lib/libsqora.so.10.1
FileUsage = 1
Driver Logging = 7

vi /etc/odbc.ini

[simple]
Driver = OracleODBC-10g
DSN = OracleODBC-10g
ServerName = MY_SID
UserID = USER
Password = PASSWORD

isql -v simple

我认为我们应该分配unixODBC的版本。如果要连接oracle12c，我们应该使用unixODBC-2.3.1
