3. Run the following queries:
This will give the number of users on the system in the past 1 hour.
SQL> select count(distinct user_id) "users" from icx_sessions where last_connect > sysdate - 1/24 and user_id != '-1';
This will give the number of users on the system in the past 1 day.
SQL> select count(distinct user_id) "users" from icx_sessions where last_connect > sysdate - 1 and user_id != '-1';
This will show the activity in the last 15 minutes.
SQL> select limit_time, limit_connects, to_char(last_connect, 'DD-MON-RR HH:MI:SS') "Last Connection time",
user_id, disabled_flag from icx_sessions where last_connect > sysdate - 1/96;
