Hi all

I am attempting to install Oracle Real Application Clusters as per the walkthrough :

"RACing ahead with Oracle on VMware - Part 1: Setting up VMware for Oracle/Intro to Virtualization/Server Consolidation"

http://www.databasejournal.com/features/oracle/article.php/3560016



The problem I have is with part 3 of this series. Basically, when I run the pre-installation check (runcluvfy.bat) I get the following error:

Error : Could not find a suitable set of interfaces for VIPs.



Please advise.

The solution to the error above that is given when running 'cluvfy' is to simply ignore it if you intend to use an IP in one of the above ranges for your VIP. The installation and configuration can continue with no corrective action necessary.
One result of this, as noted in the problem section, is that the silent VIPCA will fail at the end of the 10gR2 CRS installation.   This is because VIPCA is running in silent mode and is trying to notify that the IPs that were provided may not be fit to be used as VIP(s). To correct this, you can manually execute the VIPCA after the CRS installation is complete.  VIPCA needs to be executed from the CRS_HOME/bin directory as the 'root'  user  (on Unix/Linux)  or as a Local Administrator (on Windows):
$ cd $ORA_CRS_HOME/bin
$ ./vipca
Follow the prompts for VIPCA to select the appropriate interface for the public network, and assign the VIPs for each node when prompted.  Manually running VIPCA with the same IPs should complete successfully.

Thanks for getting back to me.

I have just run the installer for RAC and it falls down on the screen where I specify cluster configuration.

It says :

"You are missing local node, vmora01w2k3-virt.visualwin.testdomain information. Enter the public node name, the private node name and the virtual hostname for all nodes in the cluster, including the local node.

I have these set up in both hosts file and in DNS settings on the server. On the DNS server both point to 18.18.18.* depending on the node.

Any ideas?
