1. 下載oracle的客戶(hù)端程序包（30M）
只需要在 Oracle 下載一個(gè)叫 Instant Client Package 的軟件就可以了，這個(gè)軟件不需要安裝，只要解壓就可以用了，很方便，就算重裝了系統還是可以用的。
下載地址： http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html 解壓到一個(gè)目錄中即可，例如c:\oracleclient
2. 配置操作系統環(huán)境變量
NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK
TNS_ADMIN=C:\oracleclient
3. 配置連接Oracle的配置。tnsnames.ora文件到目錄C:\oracleclient?？梢詮膐racle服務(wù)器拷貝一個(gè)過(guò)來(lái)。
內容類(lèi)似：
# 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. 安裝PLSQL Developer
5. 配置PLSQL Developer（第一次可以不用登錄直接進(jìn)到PLSQL Developer）
Tools --> Preferences--> Connections,
Oracle Home內容為 C:\oracleclient
OCI library內容為C:\oracleclient\oci.dll
重新啟動(dòng)PLSQLDeveloper
完畢
