How will you find current and
maximum utilization of process/session details?
Using the below SQL you can find current number of process
and session details
Select resource_name, current_utilization, max_utilization from v$resource_limit where resource_name in ('processes', 'sessions');
Locking

===================
set linesize 230

alter session set
nls_date_format='dd-mm-yy hh24:mi:ss';
select
NAME,CTIME,PTIME,EXPTIME,LTIME,lcount from user$ where name ='PRODUACT';
CTIME is the date the user was created.
LTIME is the date the user was
last locked. (Note that it doesn't get NULLed when you unlock the user).
PTIME is the date the password was last changed.
