How to Find User Status, State, Sid, Serial# in Oracle Database

Hi, Guy's,

You can find the USER information like Status,State, SID, SERIAL# etc...which will also help you for killing sessions and also finding User-Machine locations.


For all the RAC-Database Users :-

SQL> set pagesize 50000
set linesize 5000
set long 50000
select username,status,state, to_char (logon_time,'dd-mon-yyyy hh24:mi:ss'),osuser,terminal,sid,serial#,inst_id,count(*) from gv$session
group  by  username,status,state,to_char (logon_time,'dd-mon-yyyy hh24:mi:ss'),osuser,terminal,sid,serial#,inst_id order by count(*);


For Specific Departments Users Whose Names are Starting From 'AC' :-

SQL> set pagesize 50000
set linesize 5000
set long 50000
select username,status,state, to_char (logon_time,'dd-mon-yyyy hh24:mi:ss'),osuser,terminal,sid,serial#,inst_id,count(*) from gv$session where username like 'AC%'
group  by  username,status,state,to_char (logon_time,'dd-mon-yyyy hh24:mi:ss'),osuser,terminal,sid,serial#,inst_id order by count(*);


For Specific User :-

SQL> select username,status,state, to_char (logon_time,'dd-mon-yyyy hh24:mi:ss'),osuser,terminal,sid,serial#,inst_id,count(*) from gv$session where username=('PHRASU')
     group  by  username,status,state,to_char (logon_time,'dd-mon-yyyy hh24:mi:ss'),osuser,terminal,sid,serial#,inst_id order by count(*);

How to find the user name in Oracle who is accessing particular object.

Hi Guy's,

Its very easy to find the 'User-Name' if you want to kill his session.

In my prod database where indexes are not getting rebuild even after giving the 'Rebuild-Online' option.
because this table is not getting released by the user. I already know the table name which has hold the index rebuild and then killed the sessions.


SQL> select object,owner,sid from v$access where object='MPMCSTK '


OBJECT       OWNER         SID
------------ ----------------------------------
MPMCSTK     DAVID          268
MPMCSTK     DAVID         584
MPMCSTK     JOHN          1413
MPMCSTK     KETE          1474
MPMCSTK     CATHY        842

28 rows selected.


SQL> select USERNAME,inst_id,sid,serial# from gv$session where username='DAVID';

USERNAME      INST_ID        SID          SERIAL#
------------------------------------------------------------------------
DAVID                      1              268          6921
DAVID                      1              584          2427


SQL> alter system kill session '268,6921,@1' immediate;
