Locked_mode in v$locked_object
Hi All,
I'm checking this heavily skewed data in v$locked_object. Just wondering what is this number 2,3 in locked_mode column.
can anybody give me an idea the meaning of those number?
Regards,
Dexter
Hi Dexter!
Can youe please let me know what the numerical values for lock_mode in V$locked_opbjects mean? I see an entry in the v$locked_objects with lock_mode value as 3. Can you please tell me what kind of lock it means and when the lock occurs? The link specified in the earlier thread does not contain any information about the locks and lock modes. Please help me by providing the lock-mode numeric value mapping.
Thanks!

DatabaseError: ORA-02049: timeout: distributed transaction waiting for lock
Hi all
There is script running in my database 'A' that will select some data from tables in other database through DBLINK and update some tables too. The script which 6 I am running for the past 6 monts succesfully. Yesterday I got error saying that,
DatabaseError: ORA-02049: timeout: distributed transaction waiting for lock
ORA-02063: preceding line from test
I have tested the Link and its active no issues in DBLINk
I understand the objects which I am accessing the table in locked mode,
SQL> select OBJECT_ID,SESSION_ID,PROCESS,LOCKED_MODE from v$locked_object where
SESSION_ID=121;
OBJECT_ID SESSION_ID PROCESS LOCKED_MODE
77391 121 21394 3
i
I killed the session 121 and in v$session status is Killed, but I am getting the same error repeating while running the script. And the session_id is still in locked_mode.
Could please add some light on this?
-Thanks
AntonyHi,
I have killed the session which caused blocking and the status is KILLED for the past two days. But still the object is in locked mode
SQL> select OBJECT_ID,SESSION_ID,PROCESS,LOCKED_MODE from v$locked_object where
SESSION_ID=121;
OBJECT_ID SESSION_ID PROCESS LOCKED_MODE
77391 121 21394 3
How would I resolve this any idea
-Thanks & Cheers

Query To Kill Locked Object's Session
Hi ,
Im trying to write script to getting sid & Serial# for frequently locked objects in my database.
i have tried with 3 ways as following, Pl Guide me for choosing better.
Query 1:
SELECT SID,SERIAL# FROM V$SESSION WHERE SID IN (SELECT SID FROM V$LOCKED_OBJECT WHERE OBJECT_ID IN ('34943','34957','34966')));
Query 2:
select
sess.sid,
sess.serial#
from
v$locked_object lo,
dba_objects ao,
v$session sess
where
ao.object_id = lo.object_id
and
lo.session_id = sess.sid
AND
AO.OBJECT_ID IN('34943','34957','34966');
Query 3:
select
sid,
serial#
from
select
sid,
serial#
from
v$session
) y,
select
b.session_id
from
select
object_id,
session_id,
locked_mode
from
v$locked_object
) b,
select
object_id,
object_name,
owner
from
dba_objects
where
object_name in ('PMA_DEFECT_DETAILS',
'PMA_DEFECT_HEADER',
'PMA_DEFECT_TRANS')
) c
Where
b.object_id = c.object_id
) x
Where
x.session_id = y.sid ;

To know the lock you can use the query below, you will know the sid and find the serial# from v$session.

Object locked in v$locked_object but can't find session/process blocking
Hi,
I am on database 10.2.0.5, windows x64.
A developer calls me and tells me there are locks on 3 tables, and the locks are not released.
So I run this to see which objects are locked by which session
select vlo.object_id, vlo.session_id, vlo.oracle_username, vlo.process
, DECODE(vlo.LOCKED_MODE, 0,'NONE', 1,'NULL', 2,'ROW SHARE', 3,'ROW EXCLUSIVE', 4,'SHARE', 5,'SHARE ROW EXCLUSIVE', 6,'EXCLUSIVE', NULL) LOCK_MODE
, do.owner, do.object_name, do.object_type
, vs.saddr, vs.serial#, vs.paddr, vs.username, vs.ownerid, vs.status, vs.server, vs.schemaname, vs.osuser, vs.machine, vs.program, vs.type, vs.logon_time, vs.last_call_et
, vs.blocking_session_status, vs.event#, vs.event, vs.wait_class#, vs.wait_class, vs.wait_time, vs.seconds_in_wait, vs.state
from v$locked_object vlo
inner join dba_objects do on (vlo.object_id = do.object_id)
left outer join v$session vs on (vlo.session_id = vs.sid)-----------
I get (after finding out my table locks come from SID 514)
OBJECT_ID SESSION_ID ORACLE_USERNAME PROCESS LOCK_MODE OWNER OBJECT_NAME OBJECT_TYPE SADDR SERIAL# PADDR USERNAME OWNERID STATUS SERVER SCHEMANAME OSUSER MACHINE PROGRAM TYPE LOGON_TIME LAST_CALL_ET BLOCKING_SESSION_STATUS EVENT# EVENT WAIT_CLASS# WAIT_CLASS WAIT_TIME SECONDS_IN_WAIT STATE

I run it again and I get something different, this time the lock is still there, but no session. select * from v$session where sid= 514 returns nothing.
I get
OBJECT_ID SESSION_ID ORACLE_USERNAME PROCESS LOCK_MODE OWNER OBJECT_NAME OBJECT_TYPE SADDR SERIAL# PADDR USERNAME OWNERID STATUS SERVER SCHEMANAME OSUSER MACHINE PROGRAM TYPE LOGON_TIME LAST_CALL_ET BLOCKING_SESSION_STATUS EVENT# EVENT WAIT_CLASS# WAIT_CLASS WAIT_TIME SECONDS_IN_WAIT STATE
373122 514 ROW EXCLUSIVE IRMFIN IC_PRODUCT_STATUS TABLE
373025 514 ROW EXCLUSIVE IRMFIN IC_BIN_DETAIL_STATUS TABLE
373055 514 ROW EXCLUSIVE IRMFIN IC_LOT_STATUS TABLE When I run the query later, I sometimes get another session, but the lock stays. It seems here, that I am catching the same SID on new sessions, but it is probably a different serial # than the original session locking the table rows.
I get nothing from
select * from dba_waiters;
select * from dba_blockers;
Now why are those 3 tables row locked on some rows and I can't find the session responsible? The developer tells me his application crashed and the rows are locked since.
So far ( keep in mind I am not a locking expert) the only way I found to release the locks is a DB bounce, its a test DB so no biggy.
Is this a bug? Am I missing something?
This is the second time this has happened. How can I solve this issue?
Best wishes to all.Thank you for your reply.
I do not think I can kill the session (514) it does not exist, even though v$locked_object reports tables are locked by session 514
see below

Hi,
If i query v$lock, i am returned a lot of rows with TYPE=TX and with LMOD=6 but mean while if i query v$locked_object, i don't see any objects are locked, For the same SID i find in v$lock, i also fined undo segments allocated. why i dont see any locked objects in v$locked_object?
Thanks
SalmanThis view stores all information relating to locks in the database. Important possible values of type are TM (DML or Table Lock), TX (Transaction), MR (Media Recovery), ST (Disk Space Transaction).
You're finding TX lock with LMODE=6. So your transaction is locking some rows in exclusive mode.
LMODE=6 is an exclusive lock.
More elaborative information is here:

How long does the info in V$LOCKED_OBJECT persist?
Post moved to How long does the info in V$LOCKED_OBJECT persist?
Edited by: JOE_humble on Oct 14, 2008 3:49 AMIts hard to tell beforehand what the V$ views will return. Its common for me to find stuff that I thought would long since have been aged out, or not find stuff I think should be there.

Dear friends,
Can the users be granted SELECT previlage on V$LOCKED_OBJECT or DBA_OBJECTS ? How? From which users?
with thanks in adv.
Rathnakumar RJDhi
connect sys as sysdba and grant it.
hope it helps you.

How to find out the locks in the table
Any query anybody have to find out locks in any table.
Here is a version with SID and serial# data:
set linesize 150;
set head on;
col sid_serial form a13
col ora_user for a15;
col object_name for a35;
col object_type for a10;
col lock_mode for a15;
col last_ddl for a8;
col status for a10;
break on sid_serial;
SELECT l.session_id||','||v.serial# sid_serial,
l.ORACLE_USERNAME ora_user,
o.object_name,
o.object_type,
DECODE(l.locked_mode,
