现象

Oracle 11.2.0.4的rac不能监听public ip,很奇怪:

解决

修改监听文件/u01/app/11.2.0.4/grid/network/admin/listener.ora文件,增加如下内容:

查看:

然后重启监听即可:

结果:

可见,public和vip都已经被监听了。

其它原因 (Doc ID 1597716.1)

文件/etc/nsswitch.conf的权限问题:

日志文件:/u01/app/11.2.0.4/grid/log/oarac2/agent/crsd/oraagent_grid/oraagent_grid.log

文件endpoints_listener.ora不能直接修改,因为重启监听又回到最初的状态了。

Public IP Endpoint is not registered for Listener in 11.2 RAC (Doc ID 1597716.1)

APPLIES TO:

Oracle Database - Enterprise Edition - Version 11.2.0.1 to 11.2.0.4 [Release 11.2]
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Generic (Platform Independent)

SYMPTOMS

This is two node RAC, ONS fails to start, listener starts successful, but Public IP ENDPOINT is not dynamically registered to the Listener.

- lsnrctl status shows only VIP Endpoint registered, Public IP Endpoint not registered.

$ lsnrctl status
