SEVERE: [FATAL] [INS-08106] Unexpected error occurred while loading the view ‘InventoryUI’ associated to state ‘inventoryPage’.
CAUSE: No additional information available.
ACTION: Contact Oracle Support Services or refer to the software manual.
SUMMARY:
- setSelectedIndex: 0 out of bounds.
Refer associated stacktrace #oracle.install.commons.util.exception.DefaultErrorAdvisor:6488

CAUSE

OUI was not able get the OS Group of the user which is used to install Oracle binaries, since /etc/group did not have proper permission.

SOLUTION

Make sure the installation user has read privilege to the file :  /etc/group

Default permission found on Unix systems

-rw-r--r-- 1 root root 1071 Oct 18  2013 /etc/group

To determine whether the oracle user exists and belongs to the correct groups, enter the following command:

# id oracle

If the oracle user exists, then this command displays information about the groups to which the user belongs.  The output should be similar to the following, indicating that oinstall is the primary group and dba is a secondary group:

uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)
