Assuming the raw devices are used, create an ASCII file identifying the raw volume objects on the node from which the Oracle Universal Installer is run. The DBCA requires that these objects exist during installation and database creation. When creating the ASCII file content for the objects, name them using the format:
When the ASCII file is created, separate the database objects from the paths with equals (=) signs as shown in the example below:
Specify that Oracle use this file to determine the raw device volume names by setting the following environment variable where filename is the name of the ASCII file that contains the entries shown in the example above:
setenv DBCA_RAW_CONFIG filename
ksh, bash or sh:
Add the Oracle User account
An osdba group must be defined in the /etc/group file on all nodes of the cluster. To designate an osdba group name and group number and osoper group during installation, these group names must be identical on all nodes of the UNIX cluster that will be part of the Real Application Clusters database. The default UNIX group name for the osdba and osoper groups is dba. There also needs to be an oinstall group that the software owner should have as its primary group
