Normally things are fairly quiet except on the occasion one of my power forgot to engage users. But last week I started to have notification that a session belonging to me (ESTEVENS) was blocking one or more sessions held by me. Still, he arrives at 21:00 and fades within 5 minutes before the next review. The sql code associated with the blocked session is always the same. Here is a representative sample, with company data obscured.
Block user - ESTEVENS
Machine - myserver.mycompany.org
SID - 433
OSUSER - oracle
-PROGRAM [email protected] (J001)
OBJID - 12451
Blocked user - ESTEVENS
Machine - myserver.mycompany.org
SID - 200
OSUSER - oracle
-Program [email protected] (J002)
SQL: UPDATE HS_FDS_CLASS_DATE SET FDS_CLASS_DATE = SYSDATE WHERE FDS_
By comparing the time of the block and SIDS reported with DBA_SCHEDULER_JOB_RUN_DETAILS content, I was able to follow some scheduled tasks 'load '. These jobs do a SELECT... IN... OF < db_link >. Because the table is locked is HS_FDS_CLASS_DATE, I found notes 1536085.1 describing a bug with the use frequent or simultaneous to a db_link, supposed to be fixed in 11.2.0.4 but my experience says otherwise. However, I can deal with all that.
But my real question is how to get my username attached to these sessions?

Understand your question, I hope...

It happened to me, that if I use my "DBA1' to create one job to another user"USER1", my user name is indicated as the USER name in the session, but 'The ANALYSIS of the USER' are the owner of the task.

I think it's normal, but I still don't know why.

Edit: Duh! It seems that it is documented Overview of job creation

Because no destination_name attribute is specified, the task runs on the (local) database of origin. The job runs as the user who created the work.

Kind regards

contracting of Oracle tm + idenitifying blocking sessions/proceseses + sql

Hello
Using oracle 11.2.0.3 and sometimes our etl load lock because of the argument - while having a gui tool which can identify sessions blocking, would be a good thing to have a script that allows to identify these blocking sessions, user of the os and pc who initiated the session blocking and sql blocking.
For example, the summary tables sometimes have patches ran against them and we are not aware of this so happens when not around.
Is this possible?
It is also possible to identify any tabels who the fk constraints, but Marvin Dollin have associated indexes?
Thank you

How to find block sessions on a 2 DB of RAC node?

Hi DBAs,
I know that the query that will give me the session that is blocking on a standalone DB as below:
Select l1.sid, 'BLOCKS', l2.sid from v$ lock l1, l2 of v$ lock
where l1.block = 1 and l2.request > 0 and l1.id1 = l2.id1 and l1.id2 = l2.id2;
But now I have a small question that my other DB is a node 2 CARS DB (2 instances that are on 2 different location breaks). And there seems to be some memory problems and I need to find sessions that are open for a long time and I need to kill them. Can anyone help me find the blocking in RAC environment session and also how to kill in RAC environment.
DB environment:

The error in the stored procedure, it is that it is badly written - by using the line by line (= slow-by-slow) cursor loops, in the middle of which he

are updated.

This causes the locking will be held longer than necessary.

If rewrite you it with focus on game updates, that will be faster, it will alleviate your problem.

To completely remove it, you will need to discover why a report made updates and why she strives to update the same rows.

BTW: also remove this bad Ngen.exe.

Script to kill the blocking sessions

We use Oracle 10. We have a database of test used only for training and I need to give to the teacher the ability to kill all sessions blocking when a block continues
the entire class.
My idea was to create a simple form on our Oracle containing just a single menu-button when you press on would trigger the script. Press the key
to kill each session blocking. I have no idea on how to write a script of this nature. Would appreciate any advice.
Kind regards
Sandy

You can use something like this

SQL> DECLARE
  2  CURSOR c IS
  3  SELECT c.owner,
  4        c.object_name,
  5        c.object_type,
  6        b.SID,
  7        b.serial#,
  8        b.status,
  9        b.osuser,
 10        b.machine
 11   FROM v$locked_object a, v$session b, dba_objects c
 12   WHERE b.SID = a.session_id AND a.object_id = c.object_id
 13   and c.object_name in ('JSW_CRM_C_HR_COIL_INFO','T_SPCL_BARCODE_CRS2');
 14  c_row c%ROWTYPE;
 15  l_sql VARCHAR2(100);
 16  BEGIN
 17  OPEN c;
 18  LOOP
 19  FETCH c INTO c_row;
 20  EXIT WHEN c%NOTFOUND;
 21  l_sql := 'alter system kill session '''||c_row.SID||','||c_row.serial#||'''';
 22  EXECUTE IMMEDIATE l_sql;
 23  END LOOP;
 24  CLOSE c;
 25  END;
 26  /

Be sure to use your own SQL statement in the CURSOR!

Blocking of RAC sessions

Hello
I had a look at several versions of SQL Developer and none of them seem to handle blocking sessions in the CCR that is questioning the views of $ GV. Am I missing something?
Thank you
Chris.

I would hazard a guess that it refers to:

Reports of data dictionary-> DatabaseAdministration-> locks-> block of the locks by user

If Yes, it is quite right... it uses exclusively the view V$ and therefore an incomplete view of locking in a RAC database. This is also true of the locks by report the user in the same group, incidentally.

How to find who holds a SQL lock when its not v$ session.sql_id and v$ session.prev_sql_id

Hi all
Looking a little nudge in the right direction on a strange problem with blocking locks in our database of BSE...
We occasionally will blocking locks in our EBS 12.1.3 database (11.2.0.4 CARS on OEL5).   I can easily determine the INST_ID select and SID that keeps the lock with this:
Select final_blocking_instance, final_blocking_session from gv$ session where lockwait is not null;
and can use these results to find the specific object being blocked by querying a gv$ locked_object where session_id = xxx and INST_ID select = xxx.   These sessions blocker are generally inactive to an event of "SQL * Net client message"-while they seem to be connected to the database users who need simply to commit or rollback transactions.   Usually, when I see this type of behavior, the specific application involved in the unresolved external transactions is easy to find by taking the SQL_ID (or sometimes the PREV_SQL_ID) value of gv$ session and questioning gv$ sql. I can then use this information to better understand what users are trying to accomplish and help them understand what they need to change to avoid the deadlock problem.
But recently, we have integrated the add-on of Oracle content management and it seems to have added (I suspect indirectly) triggers for many forms EBS our users work in. Now that we know these "locks blocking inactive form" - and the SQL_ID value is zero and related PREV_SQL_ID sql_text is
SELECT * FROM AXF_COMMANDS_SYN WHERE FORMID =: b1 AND (MENUTYPE = 'SPÉCIAL' MENUTYPE or = "ZOOMANDSPECIAL") AND AXF_COMMANDS_SYN. SPECIAL 'n' IS NOT NULL

Although I can see SGS $ locked_object both the text of the SQL being run by sessions which blocked the blocking the locks held by the session is on an object (for example RA_CUSTOMER_TRX_ALL) that does not seem to be at all related to AXF_COMMANDS_SYN.   The AXF schema has been added as part of the deployment of content management.

So, my thought is that a different cursor open (previous) held by the session is the real unresolved SQL that maintains the lock. Is there a way to determine the SQL_ID of this query "indirectly" from gv$ locked_object / gv$ transaction, gv$ open_cursor, etc.? I can determine what is the problem and what user, we need to talk to him - but I would really like to find the exact SQL that is involved.   I am also to establish if the new behavior is somehow contributing to locking problems blocking or just 'a Kipper"- and I think I know which statement SQL Gets the lock will help me to move forward with the investigation. I'm sure I could find this info by tracing the blocking - session but the problem occurs rarely, and I'm not able to determine which trace session until it is too late... :-)

Any recommendations would be appreciated, and my apologies for the long post...

A session may issue a followed LMD of 5 requests without issuing a commit.

Another session may be attempting a DML when the 5th request session above is running. Querying V$ session for the first session SQL_ID or PREV_SQL_ID wouldn't you say the first SQL DML.

You can walk backwards through V$ ACTIVE_SESSION_HISTORY (if you have the License Pack diagnosis) and determine all SQL_IDs of this first session if they did get captured in V$ ACTIVE_SESSION_HISTORY or DBA_HIST_ACTIVE_SESS_HISTORY. (Attention: not all SQLs are captured - particularly short-lived SQLs can't get captured)

Blocking problem

Hello
We had a blocking problem when insert 2 instructions were trying to insert into the same table. I don't see a reason why 2 commands insert should cause a blocking problem, but it was indeed happening. The table had no triggers, partitions or bitmap indexes. However the table had 2 unique index and primary key constraints.
Can someone please advice on this? What can be the reason for the impasse here?
Oracle Version: 11.1
Thank you

create table t1 (key primary number n1);

session 1: insert into t1 values (1);

session 2: insert into t1 values (2);

session 1: insert into t1 values (2); -wait session 2 to rollback or commit

session 2: insert into t1 values (1); -waiting for the session 1 to rollback or commit.

In the seconds 3 session 1 will throw an exception of blocking, session 2 will continue waiting

Collisions on the uncommitted inserts, updates or deletes on primary, unique (or foreign) keys can cause expected, which means that you can engineer blockages.

'4' is actually the 5 lock mode.

See https://orastory.wordpress.com/2011/11/23/wfg-mode-5-tm-deadlock/

You can also use the raw data of ASH in V$ ACTIVE_SESSION_HISTORY and/or DBA_HIST_ACTIVE_SESS_HISTORY to complete.

It will tell you which statement was the blocked session running and blocking the session details (but not which statement was responsible for blocking, unless you get very lucky).

However, your scenario of lock mode 5 TM could match the scenario of blocking foreign key non-indexed in the article above.

The TM, the 0x1a3b3 lock can be translated into decimal - 107443 - and used to match the object of dba_objects.object_id

#define KJUSERNL 0         /* no permissions */   (Null)

#define KJUSERCR 1         /* concurrent read */ (Row-S (SS))

#define KJUSERCW 2         /* concurrent write */ (Row-X (SX))

#define KJUSERPR 3         /* protected read */    (Share)

#define KJUSERPW 4         /* protected write */ (S/Row-X (SSX))

Username blocking which is held on the database at the time

Hello
Using oracle 11.2.0.3 and concluding that on sat morning (03:30 a table cannot be updated due to an exclusive lock.
merge into the affected table.
Nothing else, we are aware to access the table at the moment because of some process must be because of the ORA-00054 - busy resource.
Is there a way that we can identify what caused the blocking / causing the lock - happenening each week.
Thank you

You get it in history, when you get the lock again and then query the table mentioned above. In addition, to check any kind of blocking session problem use this query.

Select b.session_id, a.SERIAL #, «blocker details» a.username

session $ v has, dba_lock b

where b.session_id = a.sid

and b.blocking_others = 'block ';

Session refused to be killed
Hello
I have a serious problem with my session who refuses to be killed.
I first issuing a delete statement to this session that used to take hours, so I decided to stop the process of going through another way. So I tried to canceled the process, but he refused. I have problem alter system kill session on this session, then I got a message like the process is killed, but is not to kill. I tried later to stop and restart the database with an immediate halt, not at all, after a few minutes, I got error user cancelled process. Something strange is that if you look in the session of $ v, the session does not appear, but no matter when you issue remove another on the same table, a lock apperas automatically, where you can see the blocking and blocked session. Please how can I ride of that old deletes the session to continue with the rest of my delete.
Thank you

Aman...
We should not find ourselves first of all the correct process Id, rather than kill a couple of random connections?

Select spid in process $ v where addr = (select paddr in session $ v where sid = and serial #= )

The output can be compared to the 'ps - ef' list.
Kill only the process id.
Often a "kill - 9 'is required

DROP USER CASCADE takes forever! Cannot see all blocks... any ideas?
Hi all

I am running a script that has a cascade of user to fall, and it's been sitting there for about 3.5 hours at this point.

I ran a query to see if I could find any blocking sessions:

SQL > alter
A written file afiedt.buf

1 SELECT DECODE (ask, 0,' the owner: ',' server: '). Sess sid,
2 id1, id2, lmode, request, type
3. IN V$ LOCK
4. WHERE (id1, id2, type) IN
5 (SELECT id1, id2, type OF LOCKING WHEN demand for V$ > 0)
6 * ORDER BY id1, ask
SQL > /.

no selected line

So, I'm a bit stuck... is possible to see what maybe continues this? This is performed on a 3 x system RAC node... I think this would go pretty fast...

any ideas on what to do or what to watch?

TIA,

Cayenne
Yes, you drop the first user objects, then delete it the user. Slow user drops have been written about many times over the years. It generally works better if you don't try to do everything via a single command.

I had the same experience with drop tablespace waterfall. It is generally faster remove objects via the script, then drop the tablespace.

For now, you want to probably just wait the drop user cascade.

blocking because of the primary key constraint
Hi all

Recently, we migrated to 9.2.0.4 to 10.2.0.4. In the new version of oracle there was a strange behavior, we have 200 + oracle database user and there was too much blocking on a particular one table, we looked and looked for the cause but found nothing exact reason, then on the internet somewhere, we found that if a primary key is disabled and no there is also foreign then blocking is caused for example

CREATE TABLE TEST_MST
(
MST_COL1 NUMBER,
MST_COL2 NUMBER,
MST_COL3 NUMBER
)

CREATE TABLE TEST_DTL
(
MST_COL1 NUMBER,
MST_COL2 NUMBER,
MST_COL3 NUMBER,
DTL_COL1 NUMBER,
DTL_COL2 NUMBER,
DTL_COL3 NUMBER
)

ALTER TABLE TEST_MST ADD)
CONSTRAINT PK_TM
KEY ELEMENTARY SCHOOL
(MST_COL1, MST_COL2, MST_COL3)) ;

ALTER TABLE TEST_DTL ADD)
CONSTRAINT PK_TD
KEY ELEMENTARY SCHOOL
(MST_COL1, MST_COL2, MST_COL3, DTL_COL1, DTL_COL2)) ;

ALTER TABLE TEST_DTL ADD)
CONSTRAINT FK_TM_TD
FOREIGN KEY (MST_COL1, MST_COL2, MST_COL3)
REFERENCES TEST_MST (MST_COL1, MST_COL2, MST_COL3));

ALTER TABLE TEST_DTL
DISABLE THE CONSTRAINT PK_TD;

so, I just want to be sure that's the exact reason only blocking sessions and if yes, then why not so happning.

Thanks and Rgds,
