Oracle SQL*网络配置-虚假IP

我无法通过sql*net连接到Oracle 12数据库

向后追踪我的tnsping结果如下：

tnsping devpdb

      (SERVICE_NAME = WTF)
    )
  )

无法从此计算机解析主机IP。我不知道它是从哪里得到的这不是这个主机或路由器的NAT地址，每ping至少有30跳

tnsnames.ora：

DEVDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = tts-PowerEdge-T105)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = devDB)
    )
  )

DEVPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = tts-PowerEdge-T105)(PORT = 1521))
    (CONNECT_DATA =
      (SID = devpdb)
      (SERVER = DEDICATED)
      (SERVICE_NAME = devpdb)

DIAMONDPDB =

    (CONNECT_DATA =
      (SID = DIAMONDPDB)
      (SERVER = DEDICATED)
      (SERVICE_NAME = DIAMONDPDB)
    )
  )

/etc/hosts是：

127.0.0.1   localhost
192.168.1.2 tts-PowerEdge-T105

# The following lines are desirable for IPv6 capable hosts

太平工程：

ping tts-PowerEdge-T105 PING tts-PowerEdge-T105（192.168.1.2）56（84）字节的数据。 来自tts-PowerEdge-T105（192.168.1.2）的64字节：icmp_seq=1 ttl=64时间=0.054毫秒

我的sqlnet.ora：

# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

当我更改tnsnames.ora如下：

tnsping devpdb

      (SERVICE_NAME = devDB)
    )
  )

DEVPDB =
  (DESCRIPTION =

    (CONNECT_DATA =
      (SID = devpdb)
      (SERVER = DEDICATED)
      (SERVICE_NAME = devpdb)
    )
  )
DIAMONDPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
    (CONNECT_DATA =
      (SID = DIAMONDPDB)
      (SERVER = DEDICATED)
      (SERVICE_NAME = DIAMONDPDB)
    )
  )

WTF =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
    (CONNECT_DATA =
      (SID = WTF)
      (SERVER = DEDICATED)
      (SERVICE_NAME = WTF)
    )
  )

我明白了：

tnsping wtf

TNS-03505: Failed to resolve name

我的环境：

LD_LIBRARY_PATH=/u01/app/oracle/product/12.1.0/dbhome_1/lib
ORACLE_SID=devDB
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1

我甚至可以删除我的tnsnames.ora文件并获取原始消息，这样它就不会被使用

我尝试将我的sqlnet.ora更改为：

# sqlnet.ora Network Configuration File:      /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

#NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
NAMES.DIRECTORY_PATH= (HOSTNAME,TNSNAMES, ONAMES)

这没什么区别

因此，无论主机名适配器是什么，或者它是如何配置的，似乎都是问题所在。请注意，“使用的参数文件：”为空

我导出了TNS_管理员

export TNS_ADMIN=/home/u01/app/oracle/product/12.1.0/dbhome_1/network/admin

但仍然没有使用任何参数文件。我对该文件具有读取权限

---

我怀疑这与我的sqlnet.ora文件有关，但我已经没有想法了。

非常有趣。我不擅长在Linux下管理Oracle，但显然，首先必须强制Linux用户使用特定的

sqlnet.ora

文件。请尝试导出值为

/HOME/u01/app/ORACLE/product/12.1.0/dbhome\u 1

的

ORACLE\u HOME

变量，而不是导出

TNS\u ADMIN

，同时确保用于监听的用户可以访问

/HOME/u01/app/ORACLE/product/12.1.0/dbhome\u 1

。设置

sqlnet.ora

，以便

TNSNAMES

是

名称.目录路径中的第一个。那么xx.xxx.xxx.xx是您无法识别的IP地址，还是无法解析的FQDN？您的文件声称位于
/u01/…
中，但它们实际上在哪里-您将TNS_ADMIN设置为
/home/u01/…
？
devpdb
是否可通过dig或nslookup解析为IP？看起来TNS_ADMIN没有设置为有效路径，也没有使用默认路径，并且碰巧使用了一个别名，该别名也是一个主机…这是一个权限问题。用户无法读取该文件。文件确实在他们应该在的地方。我不必设置TNS_ADMIN。我没有安装数据库，但是一个chown oracle sqlnet.ora tnsnames.ora和chmod 644 sqlnet.ora tnsnames.ora完成了这个任务。谢谢你的努力。
