1. 下载oracle的客户端程序包（30M）
只需要在 Oracle 下载一个叫 Instant Client Package 的软件就可以了，这个软件不需要安装，只要解压就可以用了，很方便，就算重装了系统还是可以用的。
下载地址： http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html
解压到一个目录中即可，例如c:/oracleclient

2. 配置操作系统环境变量
NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK
TNS_ADMIN=C:/oracleclient

3. 配置连接Oracle的配置。tnsnames.ora文件到目录C:/oracleclient。可以从oracle服务器拷贝一个过来。
内容类似：

Java代码







# tnsnames.ora Network Configuration File: E:/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ORCLProduct =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = prmpatm1.asiapacific.hpqcorp.net)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

ORCL122 =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 16.157.133.122)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

)

# tnsnames.ora Network Configuration File: E:/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCLProduct =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prmpatm1.asiapacific.hpqcorp.net)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

ORCL122 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 16.157.133.122)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

4. 安装PLSQL Developer

5. 配置PLSQL Developer（第一次可以不用登录直接进到PLSQL Developer）

Java代码







Tools --> Preferences--> Connections,

Oracle Home内容为 C:/oracleclient

OCI library内容为C:/oracleclient/oci.dll

Tools --> Preferences--> Connections,
Oracle Home内容为 C:/oracleclient
OCI library内容为C:/oracleclient/oci.dll

如图：



重新启动PLSQLDeveloper

需要注意的是，如果是电脑上已安装了Oracle客户端，那么这里是不需要配置的。
