# Database Server Location

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

1. DB2 instance on the Infor LN server (2-Tier).
2. DB2 instance on another server using DB2 client libraries (3-tier).

If you select the DB2 instance on the Infor LN server, the environment connects directly to the DB2 instance on the same server.

Connection by an DB2 instance on another server using DB2 client libraries is normally used when the DB2 instance resides on another server than the Infor LN environment.
