I'm installing Oracle RAC 11G, this installation will be in two virtual servers, OS Linux redhat.
I began the installation with these steps
Configure Security Updates
then ask for proxy server information (nothing was entered), continue
Installation Option (don't ask anything)
then System Class (Server class selected)
(Real Application Clusters database installation)
when hit ENTER I got this errror message - (INS - 35354) The system on which you are attempting to install Oracle RAC is not part of a valid cluster.
I was looking in some forums an I found one where indicates I should indentiify these files and change some info on them;
The ouput of the above command lists the inventory_directory
Browse to the inventory.xml file in that directory. My oraInventory
You can verify that the flag CRS=true isn’t set for the $GRID_HOME
However, I couldn't find any of those files in my directories.
also, i was verifying the note [ID 1053393.1, but again, I couldn't find where to change the values for CRS.
RAC is a database in a cluster. One Database opened by one o more instances in one or more hosts.
Note: RAC is not a cluster, but a Database cluster.
To allow database be clustered, we need to install a software cluster.
We have some options, but Oracle developed your own software cluster actually named Grid Infrastructure for a cluster AKA Oracle Clusterware.
To install RAC you need first install and configure your cluster.
Before you start install Oracle cluster/RAC I recommend you start with concepts.
