DB version: 11gR2
OS : Sun Solaris 5.10
2 Node Rac
I have finished doing all the Hardware/software/SSH connectivity setup for RAC installation. Now, i have logged in as grid user and am trying to install the clusterware ('Grid Infrastructure')
I have set up Public IP and Private IP for the nodes as per oracle documentation. We don't have DNS for these nodes. So we thought of using /etc/hosts file.
Node1's: Public IP : 10.80.143.214
Node1's: Public IP : 10.80.143.215
Question1.
When i pinged 10.80.143.219, it errored out ;which means this IP is unallocated(not used by any node) so, i tried adding the following entries on /etc/hosts file of both nodes
10.80.143.219 danube-scan.scott.com danube-scan
10.80.143.219 danube-scan.scott.com
10.80.143.219 danube-scan
None of the above worked and i kept getting
INS-40718: Single Client Access Name (SCAN) name:string could not be resolved.
Can anyone show me how the SCAN entry in /etc/hosts file look like?
Question2:
From /etc/hosts file, how will the installer identify that a particular IP and hostname entry is meant for SCAN . Should the word "scan" be present in SCAN's entry?
Question3:
The grid installer prompts for
1. Cluster Name
2. SCAN Name
3. SCAN port
For a Cluster Name. I can give any name i like. Right?
Question4.
Must the SCAN name belong to a DB domanin like (scott.com as mentioned above). Can't i create a 11GR2 RAC DB without belonging to a DB Domain?
