# Database Server Location

The Database Server Location dialog box contains two different database server locations:

1. Oracle instance on the Infor LN server (2-Tier).
2. Oracle instance on another server using Oracle Net (3-Tier).

If you select the Oracle instance on the Infor LN server, the environment connects directly to the Oracle instance on the same server.

Connection by an Oracle instance on another server is normally used when the Oracle instance resides on another server than the Infor LN environment.
