SCAN_LISTENER

ora-00600Apr 14 2012 — edited Apr 16 2012

Hello team, recently I have changed scan configuration, from 1 /etc/hosts address to 3 DNS addresses but as you can see in the next output when I started the scan_listener it only show 1 listener instead of 3 listeners corresponding to the 3 scan addresses.

### Check DNS can resolve 3 ip addresses
[grid@hpnodo1a ~]$ nslookup hprac1
Server: 172.17.35.91
Address: 172.17.35.91#53

Name: hprac1.hplab.local
Address: 192.168.0.25
Name: hprac1.hplab.local
Address: 192.168.0.27
Name: hprac1.hplab.local
Address: 192.168.0.28

### Actual configuration of SCAN (only 1 address)
[grid@hpnodo1a ~]$ srvctl config scan
SCAN name: hprac1, Network: 1/192.168.0.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /hprac1.hplab.local/192.168.0.25

### Stop SCAN_LISTENER and SCAN
[grid@hpnodo1a ~]$ srvctl stop scan_listener
[grid@hpnodo1a ~]$ srvctl stop scan
[grid@hpnodo1a ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is not running
[grid@hpnodo1a ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is not running

### Change SCAN configuration
[grid@hpnodo1a ~]$ srvctl modify scan -n hprac1.hplab.local
PRCN-2018 : Current user grid is not a privileged user
[grid@hpnodo1a ~]$ su - root
Password:
[root@hpnodo1a ~]# . crs_env.sh
/u01/app/11.2.0/grid
+ASM1
[root@hpnodo1a ~]# srvctl modify scan -n hprac1.hplab.local

### Show new SCAN configuration
[root@hpnodo1a ~]# srvctl config scan
SCAN name: hprac1.hplab.local, Network: 1/192.168.0.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /hprac1.hplab.local/192.168.0.27
SCAN VIP name: scan2, IP: /hprac1.hplab.local/192.168.0.28
SCAN VIP name: scan3, IP: /hprac1.hplab.local/192.168.0.25

### Start SCAN and SCAN_LISTENER
[root@hpnodo1a ~]# srvctl start scan
[root@hpnodo1a ~]# srvctl start scan_listener
[root@hpnodo1a ~]# crs_stat -t

As you can see there are 3 scan.vip but only one SCAN.lsnr service. I understand that it should one scan.lsnr per scan.vip. Can anybody clearify this for me?

Thanks in advance,
