2、查看监听日志
HISMNG:/opt/oracle/diag/tnslsnr/HISMNG/listener/trace$ tail -f listener.log
04-APR-2018 09:10:32 * (CONNECT_DATA=(CID=(PROGRAM=)(HOST=HISMNG)(USER=oracle))(COMMAND=status)(ARGUMENTS=64)(SERVICE=LISTENER)(VERSION=186647296)) * status * 0

WARNING: Subscription for node down event still pending

3、查看官方文档
WARNING: Subscription for node down event still pending in Listener Log (文档 ID 372959.1)
官方建议关闭到这个feature
These messages are related to the Oracle TNS Listener's default subscription to the Oracle Notification Service (ONS). In a non-RAC environment it is recommended to disable this subscription.   This feature was introduced in Oracle 10g.

4、处理过程
使用grid用户，在listener.ora配置文件中添加一行SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF
然后reload监听，使配置文件生效。
lsnrctl reload listener
HISMNG:/opt/oracle/diag/tnslsnr/HISMNG/listener/trace$ vi /opt/oracle/product/11203/db/network/admin/listener.ora
"/opt/oracle/product/11203/db/network/admin/listener.ora" 13 lines, 356 characters

    )
  )
ADR_BASE_LISTENER = /opt/oracle
SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF   #line added by manual
保存退出！

5、查看监听日志文件
再次查看监听日志文件，发现告警已经不再产生，问题得以解决。
