1、首先我们要检查一下$ORACLE_HOME/network/admin下的监听文件，tns文件
[oracle@em13c admin]$ more listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/19.3.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.156)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )


[oracle@em13c admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/19.3.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.156)(PORT = 1521))


ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.156)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

2、查看我们的hosts文件
[oracle@em13c ~]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.133.156 em13c em13c.com
192.168.133.145 strong
[oracle@em13c ~]$

都没有问题，可以进数据库看一下local_listener 参数
SQL> show parameter local_l

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string      LISTENER_ORCL


SQL> alter system set local_listener ="(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.156)(PORT = 1521))" sid='orcl';

System altered.

SQL> alter system register;

System altered.

再看监听，服务正常
[oracle@em13c admin]$ lsnrctl status
