Oracle 配置客户端

1. 已安装Oracle情况下

   找到tnsnames.ora文件（D:\oracle\product\10.2.0\db_1\network\ADMIN）添加红色部分内容

   

   # tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora

   # Generated by Oracle configuration tools.

  

  # 本地

   ORCL  =    # orcl明用于连接时数据库名称

   (DESCRIPTION =

   (ADDRESS = (PROTOCOL = TCP)(HOST = zhanggaosong-PC)(PORT = 1521))

   (CONNECT_DATA =

   (SERVER = DEDICATED)

   (SERVICE_NAME = orcl)

   )

   

  # 远程 （192.168.1.125）

   orcl125=    # orcl明用于连接时数据库名称

   (DESCRIPTION =

   (ADDRESS_LIST =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.125)(PORT = 1521))   // 192.168.1.125服务器Ip

 

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

)

   )

   EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

  (ADDRESS_LIST =

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

   )

   (CONNECT_DATA =

  (SID = PLSExtProc)

   (PRESENTATION = RO)

   )

)

2 . 未安装Oracle 情况下

    解压下载的 instantclient-basic-win32-11.1.0.6.0.zip  到指定路径(如D:\oracle_client),在instantclient_11_1文件夹下新建network/admin.新建tnsnames.ora

    

  orcl=

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.125)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

)

在PL/SQL 中选择首选项如图

设置环境变量 解决乱码问题

 新建变量，设置变量名：NLS_LANG，变量值：SIMPLIFIED CHINESE_CHINA.ZHS16GBK，确定即可
