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 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 " rac-cluster" to /etc/hosts on both nodes?

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

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.

I just installed BIND on the SAN (CentOS) and used it Thanks allot :-) – Data-Base Apr 13 '12 at 12:34
its a hard coded workaround... but even in the article, the author said it should not be used in production. – Muhammad Apr 13 '12 at 12:37
