4.4 Database Link Behavior

A connection to the gateway is established through a database link when it is first used in an Oracle database session.

In this context, a connection refers to both the connection between the Oracle database and the gateway and to the DRDA network connection between the gateway and the target DRDA database. The connection remains established until the Oracle database session ends. Another session or user can access the same database link and get a distinct connection to the gateway and DRDA database.
