Oracle Universal Installer is the primary tool you use to install the Oracle RAC software.

1. Log in to Windows as a user with Administrator privileges.
   If using a different user than the one that installed Oracle Grid Infrastructure, then the installation user must be a member of the ASMDBA and ASMADMIN operating system groups.
2. Verify that you have Administrator privileges on the other nodes.
   To verify privileges, enter the following command for each node that is a part of the cluster where node_name is the name of the remote node:

   net use \\node_name\C$

3. Run the setup.exe command from the base directory of the Oracle Database 12c release 2 (12.2) installation media, and select the database type to install.
4. Provide information when prompted by Oracle Universal Installer (OUI).
   If you need assistance during installation, then click Help.
   If you encounter problems during installation, then click Details to examine the log file. The log file is located in the Oracle Inventory directory with a name that includes the time stamp (date_time) of the installation process, as shown in this example:

   C:\Program Files\Oracle\Inventory\logs\installActionsdate_time.log

   In the preceding example, the variables date and time represent the date and the time of the log file.

   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.
5. When you have completed this second and final phase of the installation, proceed to "Oracle Real Application Clusters Postinstallation Procedures" to perform the postinstallation tasks.

   Caution:

   After you complete the installation create the database, to install additional Oracle Database 12c release 2 (12.2) products in the database, you must stop all processes running in the Oracle home before you attempt to install the additional products. See "Preparing to Upgrade an Existing Oracle RAC Database" for additional information
