5.1.4 Oracle Home User Configurations for Oracle Installations

When the Oracle software installation completes, you will have one of the following configurations:

Installation Type Oracle Home user configuration

Oracle RAC with specified Oracle Home user

The Oracle Home user owns all the services run by the Oracle Database software.

Oracle RAC with Built-in Oracle Home user

The services run under the built-in LocalSystem account.

Note:

You cannot change the Oracle Home User after installation to a different Oracle Home user. Only out-of-place upgrade or move allows the Oracle Home user to be changed to or from the built-in Windows account.
