一、软件下载及环境配置
1.软件下载
到http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html下载如下三个包：
instantclient-basic-win32-10.2.0.4.zip instantclient-jdbc-win32-10.2.0.4.zip instantclient-sqlplus-win32-10.2.0.4.zip 将这三个包分别解压，然后内容放到C:/instantclient_10_2下其实一般情况下只需要instantclient-basic-win32-10.2.0.4.zip这个包就可以
然后从一台安装了oem的机器上复制%ORACLE_HOME/network/admin/tnsnames.ora也放到C:/instantclient_10_2中
2.环境变量的设置
在PATH中增加;C:/instantclient_10_2；
新建SQLPATH，LOCAL，TNS_ADMIN，LD_LIBRARY_PATH四个环境变量名，变量值均为C:/instantclient_10_2； 如果查询结果为乱码，设置set NLS_LANG=XXXX（例如SIMPLIFIED CHINESE_CHINA.ZHS16GBK）
3. 如果启动SQLPLUS时出现下面的错误:
ORA-12545: Connect failed because target host or object does not exist
试着把tnsnames.ora 中的host 改成IP地址。
二、运行
运行cmd
c:>sqlplus log SQL:>conn system/oracle@orc10g 这样就已经能连接远程服务器了 也可以这么连接： conn system/oracle@//192.168.1.179:1521/orc10g连接 C:/instantclient_10_2>sqlplus log SQL*Plus: Release 10.2.0.4.0 - Production on Thu Nov 27 14:45:51 2008Copyright (c) 1982, 2007, Oracle. All Rights Reserved. SQL> conn system/oracle@//192.168.1.179:1521/orc10g Connected. 下面看一下ociuldr应用的方法： C:/instantclient_10_2>ociuldr user=system/oracle@orc10g query="select username from dba_users" file=dba_users.txt 1550 bytes allocated for column USERNAME (1) 0 rows exported at 2008-11-27 14:49:44 29 rows exported at 2008-11-27 14:49:44 output file dba_users.txt closed at 29 rows. 这样查询结果就输出到dba_user.txt文件里面了。 配置tnsnames.ora和sqlnet.ora.。如果本机找不到示例文件，就从其他装有oracle的机器上拷一个。 我拷贝了10g和9i版本下各一份：10g下tnsnames.ora内容
