Connections and Security

This chapter describes in detail how both CORBA and EJB clients connect to an Oracle8i server session, and how they authenticate themselves to the server. The term client as used in this chapter includes client applications and applets running on a networked PC or a workstation, as well as distributed objects such as EJBs and CORBA server objects that are calling other distributed server objects, and thus acting as clients to these objects.

In addition to authentication, this chapter also discusses security in the sense of access control to objects in the database. A published object in the data server has a set of permissions that determine who can access and modify the object. Also, classes that are loaded in the data server are loaded into a particular schema, and the person who deploys the classes can control who can use them.
