SCAN Listener info

Have not touched scan listeners for ages so some very quick background commands to show scan listener info. That long took me ages to remember this so hence the note.

[oracle@dbb1 admin]$ srvctl config scan

[oracle@dbb1 admin]$ srvctl config scan_listener

[oracle@dbb1 admin]$ srvctl status scan_listener

from the above - 
(ip addresses randomised)

[oracle@dbb1 admin]$ nslookup dbb-scan.s002.ldn.oraclevcn.com

Non-authoritative answer:

Name: dbb-scan.s002.ldn.oraclevcn.com
Address: 10.157.196.159
Name: dbb-scan.s002.ldn.oraclevcn.com
Address: 10.157.196.141
Name: dbb-scan.s002.ldn.oraclevcn.com
Address: 10.157.196.230

Run again - the ip addresses will change i.e order first node "hits" second node

[oracle@dbb1 admin]$ nslookup dbb-scan.s002.ldn.oraclevcn.com

Name: dbb-scan.s002.ldngisprd.oraclevcn.com
Address: 10.157.196.141
Name: dbb-scan.s002.ldngisprd.oraclevcn.com
Address: 10.157.196.230
Name: dbb-scan.s002.ldngisprd.oraclevcn.com
Address: 10.157.196.159

Run "ip a" to see ip address info at unix level

[oracle@prdg2gis-dbb1 admin]$ ip a
