When a user, connected to via SQL*Plus to a database, issues the DISCONNECT command to disconnect from the database, the PGA for the session is not freed, e.g
USER1 connects via SQL*Plus, issues DISCONNECT statement.
USER2 connects via SQL*Plus to same database, queries V$SESSION and V$PROCESS - USER1 is not present in V$SESSION, but is still present in V$PROCESS and the PGA is not freed.
