Note: this only answers part of the question.

If you just want to know the maximum number of sessions allowed, then you can execute in sqlplus, as sysdba:

SQL> show parameter sessions

This gives you an output like:

    NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
java_max_sessionspace_size           integer     0
java_soft_sessionspace_limit         integer     0
license_max_sessions                 integer     0
license_sessions_warning             integer     0
sessions                             integer     248
shared_server_sessions               integer

The sessions parameter is the one what you want.
