INS-40719 error when Install Oracle RAC

oracleoracle-11goracle-rac

I'm tying to (learn how to) install Oracle RAC 11g on CentOS 6
all went OK so far but I get INS-40719 Error message regarding SCAN Name

I do not have DNS server and I'm not going to try to use it on this setup

I add this line to /etc/hosts

192.168.244.100 rac-cluster

then used "rac-cluster" as the SCAN name and it's still not working with the same error message!

any one can guide me on how to make it work?

1- do I have to add "192.168.244.100 rac-cluster" to /etc/hosts on both nodes?

2- do I need to edit/add any thing else on the nodes?

cheers

You can't use /etc/hosts for RAC SCAN, it needs a DNS server that have round robin name resolution capability. Its a requirement - refer here the official Oracle documentation on SCAN.

Refer here on how to configure dns for RAC SCAN.
