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：實(shí)驗(yàn)發(fā)現(xiàn)當(dāng)前有兩個(gè)監(jiān)聽(tīng)啟動(dòng)，而且大家都是使用 1521 端口，不需要在 listener.ora添加內(nèi)容。

這道題是第一次出現(xiàn)，我們?cè)瓉?lái)配置的都是會(huì)默認(rèn)端口，沒(méi)有這種配置方式，感覺(jué)沒(méi)有實(shí)際的意義。)

通過(guò)下面命令可以查看到有兩個(gè)監(jiān)聽(tīng)，而且可以直接用 lsnrctl start 來(lái)一起啟動(dòng)它。

lsnrctl status

lsnrctl status listener_1
