oracle 11g ORA 12505的问题，求高手啊

Posted 2023-04-12

初次连接的时候，出现了12505错误，看网上说是要修改listener.ora，但是我搜索到了四个，不知道该改哪一个，逐一尝试了之后也没有用，还是有问题啊
这是修改之后的
# listener.ora Network Configuration File: E:\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 = E:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:E:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = E:\app\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)
)

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

参考技术A HOST = localhost
这里，加上你的静态IP，或是计算机名
另外，你这个是静态注册，要早于database启动 参考技术B 你使用 netmanger 重新配置一下 参考技术C 修改tnsnames.ora，添加如下代码
TEST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 182.168.1.7)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = TEST)
)
) 参考技术D hosts 文件里加一下你的计算名称
然后HOST全用计算名称或者127.0.0.1 第5个回答  2012-05-03 重新配置一下监听也可。

oracle安装后tnsnames.ora内容

# tnsnames.ora Network Configuration File: D:\Develop\oracle11g\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

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


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)
    )
  )
