You can use the nslookup command to confirm that the DNS is correctly associating the SCAN with the addresses.
After installation, when a client sends a request to the cluster, the Oracle Clusterware SCAN listeners redirect client requests to servers in the cluster.
- At a command prompt, use the
nslookup command and specify the name of the SCAN for your cluster.
For example:
C:\> nslookup mycluster-scan
Server: dns3.example.com
Address: 192.0.2.001
Name: mycluster-scan.example.com
Address: 192.0.2.201
Name: mycluster-scan.example.com
Address: 192.0.2.202
Name: mycluster-scan.example.com
Address: 192.0.2.203
