1.Oracle官網下載instantclient

解壓到D:\zl\instantclient_11_2

2.配置環境變量

1. ORACLE_HOME = D:\zl\instantclient_11_2
2. TNS_ADMIN = D:\zl\instantclient_11_2
3. NLS_LANG = SIMPLIFIED CHINESE_CHINA.ZHS16GBK

3.在D:\zl\instantclient_11_2文件夾下創建兩個文件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 = 要訪問的數據庫地址)(PORT = 1521))
)

4.配置plsqldevloper-->工具-->首選項-->連接

5.重啟成功

不安裝Oracle數據庫使用plsqldevloper
