1.静态注册默认端口多个服务名配置，listener.ora
[oracle@db01 admin]$ pwd
/u01/app/oracle/product/19.3.0/dbhome_1/network/admin
[oracle@db01 admin]$ cat listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = db01)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER=
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl1)
(ORACLE_HOME =/u01/app/oracle/product/19.3.0/dbhome_1)
(SID_NAME = orcl)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl2)
(ORACLE_HOME = /u01/app/oracle/product/19.3.0/dbhome_1)
(SID_NAME = orcl)
)
)
上边是构建数据库自动创建监听时候的一些配置，如果采用默认，全部为动态注册，以下是追加，后边不在显示
修改完listener之后使用lsnrctl reload重新加载
如果监听比数据库启动的晚，默认一分钟之后数据库PMON进程会注册，否则可以使用alter system register手动注册
重新加载监听文件即可，lsnrct reload，可以看到提供了两个服务名orcl1和orcl2
[oracle@db01 admin]$ lsnrctl reload

2.非默认端口多个监听配置
修改listener.ora文件
[oracle@db01 admin]$ cat listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = db01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = db01)(PORT = 1522))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER=
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl1)
(ORACLE_HOME =/u01/app/oracle/product/19.3.0/dbhome_1)
(SID_NAME = orcl)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl2)
(ORACLE_HOME = /u01/app/oracle/product/19.3.0/dbhome_1)
(SID_NAME = orcl)
)
)
[oracle@db01 admin]$ lsnrctl reload
[oracle@db01 admin]$ sqlplus c##hbhe/wwwwww@192.168.56.101:1521/orcl1
