1.必须安装客户端可以连接到数据库

2.数据库服务器监听器必须要静态注册

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = d10063)(PORT = 1521))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
      )
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\oracle\ora92)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = gsid)
      (ORACLE_HOME = D:\oracle\ora92)
      (SID_NAME = paul)
    )

红色部分就是新增内容

3.数据库验证方式 必须为密码验证

SQL> show parameter pass

NAME                                 TYPE        VALUE
