As grid user:


1. Modify SCAN listener port:
grid@OSS-FWKT-DB1:/home/db/grid$ srvctl modify scan_listener -p 1521
grid@OSS-FWKT-DB1:/home/db/grid$  srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
grid@OSS-FWKT-DB1:/home/db/grid$ lsnrctl status listener_scan1

2. Restart SCAN listener so the new port will be effective:
grid@OSS-FWKT-DB1:/home/db/grid$ srvctl stop scan_listener


或者As grid user
OSS-FWKT-DB1[/u01/db/grid/product/11.2.0/bin]#./srvctl stop scan_listener
PRCC-1016 : LISTENER_SCAN1 was already stopped
PRCR-1005 : Resource ora.LISTENER_SCAN1.lsnr is already stopped


OSS-FWKT-DB1[/u01/db/grid/product/11.2.0/bin]#./srvctl start scan_listener
OSS-FWKT-DB1[/u01/db/grid/product/11.2.0/bin]#./srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
grid@OSS-FWKT-DB1:/home/db/grid$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node oss-fwkt-db1


另外一个节点：
grid@OSS-FWKT-DB2:/home/db/grid$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node oss-fwkt-db1                                                           
3. Modify Database remote_listener：


SQL> alter system set remote_listener='fwktdb-scan:1621' scope=both sid='*';
System altered.
SQL> alter system register;
System altered.
SQL> show parameters remote_listener
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
remote_listener                      string      fwktdb-scan:1621
