To configure SDP, Run the below commands

If your Oracle Database runs on an Infiniband network, you can greatly benefit by switching from TCP to SDP for DB to app communications

srvctl config scan_listener
srvctl modify scan_listener   -p TCP:1521,/SDP:1521

lsnrctl status
srvctl modify listener -l LISTENER  -p SDP:1521

Change the Oracle clusterware address

crsctl stop cluster -all
crsctl start crs
oifcfg getif

oifcfg delif -global aggrpub1/10.10.10.0
oifcfg setif -global aggrpub1/10.10.10.0:public

Re-start all clusterware apps

crsctl start cluster -all

Change the listner

First get the current Configuration

srvctl status scan
srvctl config scan

Stop SCAN and SCAN_LISTENER

srvctl stop scan_listener
srvctl stop scan

Modify / Change SCAN / Change SCAN name or new IPs on different subnet

srvctl modify scan -n rac-scan

crsctl modify resource ora.net1.network -attr "USR_ORA_NETMASK=255.255.254.0"
crsctl modify resource ora.net1.network -attr "USR_ORA_IF=db.pub0"
crsctl modify resource ora.net1.network -attr "USR_ORA_SUBNET=172.20.8.0"

To get a list of all properties

crsctl status resource -f|less
$GRID_HOME/bin/srvctl modify scan_listener -u
$GRID_HOME/bin/srvctl start scan_listener
