不装Oracle应用PL/SQL Devloper

?1, 从http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html 中 Download Instant Client，注意2个basic包下一个即可，不推荐basiclite (我下载的是约45M的那个)（下载的时候要邮箱注册）?

2,在磁盘创建上目录，解压过去，最终解压文件会在同一个目录下。比如解压到c:\oracleclient?

3,创建目录c:\oraclient\network\admin?

4,创建文件tnsnames.ora 内容如下（也可以把你原来的拷贝过来覆盖就行）?
oracledata =?
(DESCRIPTION =?
(ADDRESS_LIST =?
(ADDRESS = (PROTOCOL = TCP)(HOST = yourhostIp )(PORT = 1521))?
)?
(CONNECT_DATA =?
(SERVICE_NAME = yourSID )?
)?
) ?

5,设置pl/sql Developer的perference：?
oracle_home: "c:\oraclient\"?
OCI Library:“c:\oraclient\oci.dll”?

6. 解决中文乱码问题，select?*?from?v$nls_parameters;

根据查询出的服务器编码设置环境变量

NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK ?或

NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHSUTF8??或

NLS_LANG=AMERICAN_AMERICA.AL32UTF8

?

7.重启pl/sql developer, 输入用户名密码，以及tnsnames.ora设置的oracledata?
