1.3.4 About the Oracle Validated Configuration RPM
If the Linux distribution is Oracle Linux, or Red Hat Enterprise Linux, and you are an Unbreakable Linux customer, then you can complete most preinstallation configuration tasks by using the Oracle Validated Configurations Setup RPM, available from the Unbreakable Linux Network (ULN), or available on the Oracle Linux DVD disks.

When it is installed, the Oracle Validated Configuration RPM does the following:

•Automatically installs any additional packages needed for installing Oracle Grid Infrastructure and Oracle Database.

•Creates an oracle user, and creates the oraInventory (oinstall) and OSDBA (dba) groups for that user

•Sets and verifies sysctl.conf settings, system startup parameters, user limits, and driver parameters to values based on recommendations from the Oracle Validated Configurations program
