The IP addresses for rac-scan are not attached to any network adapter therefore are not resolvable, its a test setup just to check out the grid infrastructure, I have setup the nodes on vmware workstation.
Should I add another adaptor, one each on both nodes, and assign the rac-scan ips to them ?
i don`t think you need a other adapter for the scan. The Installer checks your scan is setup correct, which means it should not apear in your hosts file. SCAN Adapter must be in a simple setup configured in the DNS not in the hosts.
In your setup the host cannot resolve to a second ip address, because it search from the first line of your hosts to the first finding. In this case never a second IP can be resolved.
If you want this setup i suggest to setup a small named name server to do this for you.
Solutions for Typical 11gR2 Grid Infrastructure/RAC Database runInstaller Issues [ID 1056713.1]
The problem was with the name in the scan name box on the installer which by default is scan-cluster when I changed it to rac-scan it went through ( my mistake ).
However I have a new problem now may be I should open a new thread for that ?
The problem is the high memory usage by the oracle installer which eats up too much memory which freezes my VM and I don't have enough RAM to allocate more, so what I am looking for is to limit the Installer to a specific memory size usage.
Do you have any idea how can I do that, the installer is using Java and it runs so many JREs in a single process and I have no clue how to limit it to a max memory size.
