配置文件和sqlplus简单使用

oracle简单配置文件

数据文件目录

D:\app\inmeditation\oradata\orcl

• 以.CTL结尾得的文件是数据库的控制文件
• 以.LOG结尾的是数据库日志文件
• 以.DBF结尾的是数据文件,真正存储数据

监听器文件listener.ora

D:\app\inmeditation\product\11.2.0\dbhome_1\NETWORK\ADMIN

# listener.ora Network Configuration File: D:\app\inmeditation\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\inmeditation\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\inmeditation\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\inmeditation\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\inmeditation\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = sunlizhao)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = D:\app\inmeditation

ADR_BASE_LISTENER = D:\app\inmeditation --数据库安装的基础目录

HOST解释
刚安装完成后此处可能是计算机名称,
如果连接时提示没有监听器可以改成localhost,可以正常使用
此处改成ip,别的计算机就可以访问你的数据库了

本地网络名称/数据库连接串

SCOTT =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )
