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
