Direct Oracle Access will attempt to initialize Net8 when the first session connects to the database, so you will not have any problems using the components on a PC where Net8 is not installed as long as you do not connect.
To test if Net8 (or SQL*Net) is installed, call InitOCI (located in the OracleCI unit). This procedure will raise an exception with an appropriate message if Net8 is not installed.
