oracle rac監聽和oracle單節點監聽不同，rac監聽分為遠程監聽和本地監聽：
-
遠程監聽即remote_listener也是scan_listener
-
本地監聽即local_listener也是listener
local_listener 默認不需要配置，默認配置指向1521端口，對於需要單實例連接rac數據庫實例且對端口有要求的情況，需要改變本地監聽端口指向tns里的連接字符串，而在rac配置中默認指向本節點的vip。
remote_listener指向的是scan監聽名，需要遠程監聽配置
1、修改遠程監聽端口
單節點執行
1.1 查看遠程監聽狀態
切換至grid賬號下
[grid@db1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521 #遠程監聽端口為1521
[grid@db1 ~]$ lsnrctl status LISTENER_SCAN1

scan_listener如果不在節點1，則在另外一個節點查看
1.2 修改SCAN listener端口
在grid用戶下進行，命令格式如下
Modify SCAN listener port:
$GRID_HOME/bin/srvctl modify scan_listener -p
Update 11gR2 database init.ora parameter: alter system set remote_listener=':' scope=both;
示例：
[grid@db1 ~]$ $GRID_HOME/bin/srvctl modify scan_listener -p 1525
1.3 為監聽注冊實例
切換到oracle節點執行

1.4 重啟遠端監聽scan listener生效新端口
切換至grid
[grid@db1 ~]# srvctl stop scan_listener
[grid@db1 ~]# srvctl start scan_listener
1.5 確認遠端監聽狀態
[grid@db1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1525
[grid@db1 ~]$ lsnrctl status LISTENER_SCAN1

發現rac集群遠端監聽端口已經修改完畢
使用sqlplus連接正常
2、修改本地監聽端口
雙節點都要執行
2.1 獲取本地監聽程序配置信息
切換到grid執行
[grid@db1 ~]$ srvctl config listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1521 #本地監聽端口為1521
[grid@db1 ~]$ lsnrctl status #查看監聽狀態

發現節點1得本地監聽端口已經修改完成，在節點2重復上述步驟，完成節點2本地監聽端口得修改即可
使用sqlplus連接正常
