5.1.5 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 Grid Infrastructure with a domain user specified for the Oracle Home User |
The Oracle Home user owns the Oracle Grid Infrastructure Management Repository service. The other services are run under the built-in Administrator account, except for the listeners, which run as LocalService (a built-in Windows account). |
|
Oracle Grid Infrastructure with the Windows built-in Administrator account as the Oracle Home User |
The Oracle Grid Infrastructure services are run under the built-in Administrator account, except for the listeners, which run as LocalService. |
|
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.
