oracle 局域网映射设置

oracle 局域网映射设置

本Oracle 11g r2的局域网以及外网外网映射的设置：

• 使用Navicat远程连接Oracle报错ORA-28547
• 远程连接Oracle报错ORA-12541

---

问题一：使用Navicat远程连接Oracle报错ORA-28547

使用Navicat远程连接Oracle报错ORA-28547
使用navicat自身的oci.dll版本,是跟我安装的Oracle数据库是不相符的。
Oracle 11g instantclient文件 链接: https://pan.baidu.com/s/1-orRA5Ndv51WX49SmFi4XQ 密码: b5ht
解决方式：

找到下载文件下的oci.dll文件

至此navicat的问题解决。
如果还没有报错，那就是oracle服务器端监听配置错误，网上多数是修改listen.ora，tnsnames.ora这两个配置文件。
listen.ora，tnsnames.ora监听文件，根据网上教程host上的ip改来改去都没有解决。
listen.ora用计算机的主机名(iZbmiox5uhugkrZ)[主机名消失解决1.通过oracle应用程序配置，2.win计算机属性]

# listener.ora Network Configuration File: D:\app\Administrator\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\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
    (SID_DESC =
      (SID_NAME = ORCL)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
      (GLOBAL_DBNAME = ORCL)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = iZbmiox5uhugkrZ)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app\Administrator

tnsnames.ora host,无关localhost,127.0.0.1,ip,与远程连接无关，oracle数据库物理文件在本机即可。

# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\tnsnames.ora

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

打开oraclean应用程序，orcle net configuration Assiatant

远程连接Oracle报错ORA-12541

ORA-12541 没有监听器，内网映射，首先确保oracle的标准端口1521 是否暴露出来。其次就是检查对应的监听服务是否开启。
