A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned a unique identifier (or session ID). The statement that is true about session state management in Oracle APEX is:
APEX Sessions are logically and physically distinct from Oracle database sessions used to service page requests. APEX Sessions are stored in memory within an Application Express engine process while Oracle database sessions are stored in memory within an Oracle database process. The other statements are false because:
A user can run multiple instances of an application simultaneously in different browser programs by using different session IDs.
Multiple number of sessions can exist in the database at the same time for different users or applications.
