不安装Oracle数据库使用plsqldevloper

1.Oracle官网下载instantclient

解压到D:zlinstantclient_11_2

2.配置环境变量

1. ORACLE_HOME = D:zlinstantclient_11_2
2. TNS_ADMIN = D:zlinstantclient_11_2
3. NLS_LANG = SIMPLIFIED CHINESE_CHINA.ZHS16GBK

3.在D:zlinstantclient_11_2文件夹下创建两个文件tnsnames.ora和listener.ora

tnsnames.ora

ymdb =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.8)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = dbname)
    )
  )

listener.ora

LISTENER1 =  
(DESCRIPTION =  
    (ADDRESS = (PROTOCOL = TCP)(HOST = 要访问的数据库地址)(PORT = 1521))
)

4.配置plsqldevloper-->工具-->首选项-->连接
