Oracle OCP 19c 认证考试1Z0-082考试题库(第7题)-CUUG内部学员版082题库解析

In the spfile of a single instance database, LOCAL_LISTENER is set to LISTENER_1.

The TNSNAMES.ORA file in $ORACLE_HOME/network/admin in the database home contains:

LISTENER_1=

(ADDRESS=

(PROTOCOL=TCP)

(HOST=host1.abc.com)

(PORT=1521)

)

Which statement is true?

A. Dynamic service registration cannot be used for this database instance

B. The LREG process registers services dynamically with the LISTENER_1 listener

C. LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration

D. There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database instances

E. The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service Registration

Answer: D

(解析：实验发现当前有两个监听启动，而且大家都是使用 1521 端口，不需要在 listener.ora添加内容。

这道题是第一次出现，我们原来配置的都是会默认端口，没有这种配置方式，感觉没有实际的意义。)

通过下面命令可以查看到有两个监听，而且可以直接用 lsnrctl start 来一起启动它。

lsnrctl status

lsnrctl status listener_1
