Oracle Universal Installer (OUI) is the primary tool you use to install Oracle RAC One Node software.
C:\Program Files\Oracle\Inventory\logs\installActionsdate_time.log
Caution:
The Oracle home name and path that you provide during database installation must be different from the home that you used for the Oracle Grid Infrastructure software. DO NOT install the Oracle Database with Oracle RAC software into the same home in which you installed Oracle Grid Infrastructure software.Note:
Because Oracle ASM is part of the Oracle Grid Infrastructure home, it cannot be upgraded during an Oracle RAC installation.
