    • Starting with Oracle Database 12c Release 1 (12.1), Oracle Database on Microsoft Windows supports the use of an Oracle Home User, specified at the time of installation. This Oracle Home User is used to run the Windows services for a Oracle Home.This user is associated with an Oracle Home and cannot be changed to a different user post installation
    • Different Oracle homes on a system can share the same Oracle Home User or use different Oracle Home Users.
    • The Oracle Home User is different from an Oracle Installation User. The Oracle Installation User is the user who requires administrative privileges to install Oracle products. The Oracle Home User is used to run the Windows services for the Oracle Home.
      The window provides the following options:
    • If you select "Use Existing Windows User", the user credentials provided must be a standard Windows user account (not an administrator). 
      • If this is a single instance database installation, the user can be a local user, a domain user, or a managed services account. 
      • If this is an Oracle RAC database installation, the existing user must be a Windows domain user. The Oracle installer will display an error if this user has administrator privileges.
    • If you select "Create New Windows User", the Oracle installer will create a new standard Windows user account. This user will be assigned as the Oracle Home User. Please note that this user will not have login privileges. This option is not available for an Oracle RAC Database installation.
    • If you select "Use Windows Built-in Account", the system uses the Windows Built-in account as the Oracle Home User. 
  7. In the "Typical Install Configuration" window,Change: 
    • Oracle base name & add the Oracle Home User user you have created in the breivious screen as (OrclUser
    • Global database name to (orcl).
  8.  Enter the "Administrative password" as (Oracle_1). This password will be used later to log into administrator accounts such as SYS and SYSTEM. Click Next.Note:
    • By default, the installer creates a container database along with a pluggable database called "pdborcl". The pluggable database contains the sample HR schema. 
  9. The prerequisite checks are performed and a Summary window appears. Review the settings and click Install.Note:
    • Depending on your firewall settings, you may need to grant permissions to allow java to access the network. 
  10. After the Database Configuration Assistant creates the database, you can navigate to https://localhost:5500/em as a SYS user to manage the database using Enterprise Manager Database Express. You can click "Password Management..." to unlock accounts. Click OK to continue. 

  11. The Finish window appears. Click Close to exit the Oracle Universal Installer.
