当侦听器设置为主机 IP 地址时，与 Oracle DB 19c 的连接失败

  • 772

我是 Oracle DB 的新手，需要帮助解决以下问题。

我正在使用sqlplus (SQL*Plus: Version 21.1.0.0.0) 连接到Oracle DB 19c。

声明：当我将文件中的 IP 更改为“ ”时，我可以从192.168.0.109主机（如下：192.168.0.108192.168.0.1060.0.0.0localhostlistener.ora

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

面临的问题：当我将文件中的 IP 更改为主机 IP ( )时，无法从 VM ( 192.168.0.108) 或 LAN ( ) 中的其他系统进行连接。请在下面找到修改：192.168.0.106192.168.0.109listener.oralistener.ora

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.109)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

错误详情： sqlplus工具报错如下：

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

现在，让我也分享一下tnsnames.ora文件的内容（如果需要）：

LISTENER_POLA =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


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

POLA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pola)
    )
  )

更多细节：

  1. Oracle DB 所在的主机 (192.168.0.109) 可从包括 VM 在内的所有其他系统访问
  2. telnet 192.168.0.109 1521所有系统都显示它已连接。
  3. VM 在 Oracle Virtual Box 6.1 上运行并配置为桥接模式。
  4. Oracle DB 19c 和 VM 在 Windows Server 2016 之上运行。

查询： 当listener.ora文件配置了主机系统的IP地址（192.168.0.109）时，我需要做哪些配置才能使sqlplus可以从同一局域网内的任何系统连接到Oracle DB？

    也许在你的 listener.ora 中添加这样的东西：

    SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = POLA)
      (ORACLE_HOME= C:\Polarbear\WINDOWS.X64_193000_db_home)
      (SID_NAME = POLA)
    )
  )

    您可以运行此查询来验证您的全局名称：

    select global_name from global_name;

    SID 应该是

    select INSTANCE_NAME from v$instance;
