local_listener参数有两种书写格式，提供了不同的功能。
监听文件上，1521和1526端口上都有动态监听端口。
[oracle@dbsv admin]$ cat listener.ora
LISTENER=
(DESCRIPTION=

LSNR2=
(DESCRIPTION=

(ADDRESS=(PROTOCOL=ipc)(KEY=extproc2)))
[oracle@dbsv admin]$ cat tnsnames.ora
prod=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=dbsv)(port=1521)))
(CONNECT_DATA=(SERVICE_NAME=PROD)(SERVER=dedicated)))
lsnr2 =
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS = (PROTOCOL = TCP)(HOST = dbsv)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = dbsv)(PORT = 1526))
)
) 写法一：将
数据库动态注册到单独端口的监听上
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=dbsv)(PORT=1526))';
