配置多端口的动态注册
1 修改监听配置文件
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

lsnr =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1522))
)
)

2 设置local_listener参数，数据库启动后动态向两个监听主动注册
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=rac1)(PORT=1522))(ADDRESS=(PROTOCOL=tcp)(HOST=rac1)(PORT=1521)))';

System altered.

3 启动监听

lsnrctl start listener
lsnrct start lsnr

4 查看监听状态
racle@rac1 admin]$ lsnrctl status listener

目前两个监听都已经知道prod数据库的存在。

6 配置静态注册，在搭建dg环境，远程启动数据库等特殊需要时使用，静态注册就是将数据库信息直接写入listener.ora的配置文件。

SID_LIST_lsnr=
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME =prod)
(ORACLE_HOME = /oracle/base/19.3)
(SID_NAME = prod)
)
