windows远程链接oracle

首先下载oracle客户端

解压在E:\oracleClient\instantclient_11_2该路径下。进入到instantclient_11_2下创建目录 NETWORK，然后再NETWORK下建立目录ADMIN。在ADMIN目录下建立tnsnames.ora文件，在该tnsnames.ora文件中添加 :

ECSTDBY =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.11)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ecstdby)
    )
  )

    TEST =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.0.0.1)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = orcl)
        )
      )

192.168.0.11--为数据库所在机器ip

环境变量的配置

在环境变量添加TNS_ADMIN，值为tnsnames.ora所在路径。

如F:\oracleClient\instantclient_11_2\NETWORK\ADMIN\tnsnames.ora

设置ORACLE的语言，添加环境变量NLS_LANG，值为AMERICAN_AMERICA.AL32UTF8

如果出现乱码可用SIMPLIFIED CHINESE_CHINA.ZHS16GBK

下载并安装PLSQL Developer

安装完成后进入PLSQL Developer，选择tools->preferences->connection

Oracle Home

F:\oracleClient\instantclient_11_2

OCI library

F:\oracleClient\instantclient_11_2\oci.dll

保存,就可以使用了
