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：
1 2 3 4 5 6 7 | LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.7.81)(PORT = 1522)) (ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.7.83)(PORT = 1522)) ) ) |
查看：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | [root@abrac1 admin]# cat endpoints_listener.ora LISTENER_OARAC1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=abrac1-vip)(PORT=1522))(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1522)(IP=FIRST)))) # line added by Agent [root@oarac1 admin]# cat listener.ora LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.7.81)(PORT = 1522)) (ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.7.83)(PORT = 1522)) ) ) [root@abrac1 admin]# pwd /u01/app/11.2.0.4/grid/network/admin [root@abrac1 admin]# |
然后重启监听即可：
1 2 3 4 5 6 7 8 9 | srvctl stop listener srvctl start listener -- 检查 tnsping 172.30.7.81:1522/abclogy tnsping 172.30.7.82:1522/abclogy tnsping 172.30.7.83:1522/abclogy tnsping 172.30.7.84:1522/abclogy tnsping 172.30.7.85:1522/abclogy |
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：
1 | chmod 666 /etc/nsswitch.conf |
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
