Centos 7安装Oracle 12c后的Java监听器故障解决

oracle 12 listener 远程访问

在Centos 7上完成Oracle 12c的安装后,现在我尝试允许在我的PC上(通过SQL Delopper)访问服务器 . 但问题是当我这样做时:

lsnrctl status

我收到此错误:

TNS-12541: TNS:no listener

TNS-12560: TNS:protocol adapter error

TNS-00511: No listener

Linux Error: 2: No such file or directory

所以,我尝试用以下方式启动监听器:

lsnrctl start

我收到这个错误:

TNS-01198: Listener failed to initialize valid node list

NL-07007: internal error

NL-00408: cannot find or read value

NL-00408: cannot find or read value

NL-00408: cannot find or read value

然后我添加了,因为他告诉listener.ora文件中的以下行

VALID_NODE_CHECKING_REGISTRATION_ = OFF

但没有变化 .

To finish, this is my listener.ora file:

#listener.ora Network Configuration File: /home/oracle/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora

#Generated by Oracle configuration tools.

VALID_NODE_CHECKING_REGISTRATION_ = OFF

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 84.254.25.9)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

)

有没有人有办法解决吗?
