How to change/Modify SCAN Listener port in oracle RAC

 CHANGE  SCAN LISTENER PORT IN RAC DATABASE
================================================

Step 1:- verify current status and port of scan listener 

[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac2
SCAN VIP scan2 is enabled
SCAN VIP scan2 is running on node rac1
SCAN VIP scan3 is enabled
SCAN VIP scan3 is running on node rac1
[grid@rac1 ~]$



Step 2:-  Change port number of the SCAN LISTENER

[grid@rac1 ~]$ srvctl modify scan_listener -p 1585
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1585
[grid@rac1 ~]$

Step 3:- Restart SCAN LISTENER using below command 

[grid@rac1 ~]$ srvctl stop scan_listener
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl start scan_listener
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac2
SCAN VIP scan2 is enabled
SCAN VIP scan2 is running on node rac1
SCAN VIP scan3 is enabled
SCAN VIP scan3 is running on node rac1
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1585
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1585
[grid@rac1 ~]$
[grid@rac1 ~]$

Step 4:- Modify remote_listener parameter in each rac instance  also change port number in  tns entries

Before database stop change 

alter system set remote_listener='rac-scan:1585' scope=both sid='*';

Bounce database
[grid@rac1 ~]$ srvctl stop database -d orcl
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl start database -d orcl
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node rac1
Instance orcl2 is running on node rac2
[grid@rac1 ~]$
[grid@rac1 ~]$ lsnrctl status LISTENER_SCAN2
