Table lock vs dead lock

Hi all,
could you explain the root of difference between table lock and dead lock ?
Thanks.

FOR UPDATE cursor is causing Blocking/ Dead Locking issues

Hi,
I am facing one of the complex issues regarding blocking / dead locking issues. Please find below the details and help / suggest me the best approach to ahead with that.
Its core Investment Banking Domain, in Our Day to day Business we are using many transaction table for processing trades and placing the order. In specific there are two main transaction table
1)     Transaction table 1
2)     Transaction table 2
These both the tables are having huge amount of data. In one of our application to maintain data integrity (During this process we do not want other users to change these rows), we have placed SELECT …………….. FOR UPDATE CURSOR on these two table and we have locked all the rows during the process. And we have batch jobs (shell scripts ) , calling this procedure , we will be running 9 times per day 1 hrs each start at 7:15AM in the morn finish it up in the eve 5PM . Let’s say. The reason we run the same procedure multiple times is, our business wants to know the voucher before its finalized. Because there is a possibility that order can be placed and will be updated/cancelled several times in a single day. So at the end of the day , we will be sending the finalized update to our client.

Current Program will look like:

CURSOR cursor_update IS
SELECT col1, col2 … FROM transaction table2 t2 , transaction table t1

AND t1.id_flag = ‘Y’
AND t1.DML_ACTION = ‘U’,’D’ -- will retrieve the records which are updated and deleted recently for the inserted records in transaction table 1 for that particular INSERT..
FOR UPDATE OF t1.id_no,t1.id_flag;

INSERT INTO transaction table2 ( id_no , dml_action , …. ) VALUES (v_upload.id_no , ‘I’ , … ) RETURNING v_upload.id_no INTO v_no -- I specify for INSERT
/********* Updating the Flag in the source table after the population ( N into Y ) N  order is not placed yet , Y  order is processed first time )

SET id_FLAG = ‘Y’
WHERE id_no = v_no;
END LOOP;
EXCEPTION WHEN OTHER THEN
DBMS_OUTPUT.PUT_LINE( );
END; -- block2 end
END app_proc; -- Main block end
Sample output in Transaction table1 :

01 1,835 4300 12/JUN/2009 N I ( these DML Action will be triggered when ever if theres in any DML operation occurs in this table )
02 1,675 3300 12/JUN/2009 Y U
03 4475 6500 12/JUN/2009 N D
Sample output in Transaction table2 :

001 01 1,835 4300 12/JUN/2009 11:34 AM ( 2nd cursor will populate this value , bcoz there s an update happened for the below records , this is 2nd voucher

03 0 1,235 4300 12/JUN/2009 10:30 AM
Now the issues is :
When these Process runs, our other application jobs failing, because it also uses these main 2 tranaction table. So dead lock is detecting in these applications.
Solutin Needed :
Can anyone suggest me , like how can rectify this blocking /Locking / Dead lock issues. I wants my other application also will use this tables during these process.

Maran

Here's the thing I myself have an Ipad 3 that I got from Ebay that is activation locked and I have the same issue. Can't get the info. Well,since Apple conveniently decided to discontinue selling the Ipad 3 the only way I could get one was to buy a used one,so it looks to me like they could have some mercy and help a person unlock the thing. We're not dishonest people that go around stealing things,yet because of Apple's brilliant(I use that term sarcastically) idea to put this stupid new crap in place people like us who have to buy second-hand products have to suffer and get screwed out of money we had to save up to buy this stuff! And all anyone can come up with is "well boohoo" or "tough luck" or whatever! But,what about the rights of the rest of us?! Some of you may find this a tad rude, but oh well,tough luck!
On the other hand, there are those of us that appreciate the theft protection provided by the latest IOS.
There are certain things to watch out for when purchasing used devices of any sort, the first of which is to ensure that you're not buying stolen property. Since you are unable to obtain cooperation from the seller, perhaps your device was stolen!

DEAD LOCKS on table ARFCSSTATE

Please help!
Essentially the problem is that anything that updates the customer master (T/C BP) causes DEAD LOCKS on table ARFCSSTATE and the queues either slow down terrible or they hang (stop). When one tries to delete an entry in the queue a screen dump takes place DBIF_RSQL_SQL_ERROR in ARFC_RUN.
We are using: CRM 3.0 with the following service packs:
SAP Basis release 610 level 38
SAP ABA Release 50A level 38
BBPCRM Release 300 level 17
Points will be given.
Thank you.

Hi Surendra,
I was expirenced with the error, Basis people had resolved that for me,
better to post this issue to them,
this problem for all data sources or any perticulat data source when scheduling infopackage.

Frequenet dead locks in SQL Server 2008 R2 SP2

Hi,
We are experiencing frequent dead locks in our application. We are using MSSQL Server 2008 R2 SP2 version. When our application is configured for 5-6 app servers, this issue is occurring frequently.
But, when the same application is used with the MSSQL Server 2008 R2 or SQL Server 2012, we don't see the dead lock issue. From the error lock and sql trace, the error message is thrown for the database table JobLock. We have a stored procedure to insert/update
for the above table when the job moves from one service to other. The same procedure works fine when used with the 2008 R2 and SQL Server 2012 Version.
Is the above issue related to the hotfix from the below url?
http://support.microsoft.com/kb/2703275
Following error message is seen frequently in the log file.

If you are having deadlock trouble in your SQL Server instance, this recipe demonstrates how to make sure deadlocks are logged to the SQL ServerManagement Studio SQL log appropriately using
the DBCC TRACEON, DBCC TRACEOFF, and DBCC TRACESTATUS commands. These functions enable, disable, and check the status of trace flags.
To determine the cause of a deadlock, we need to know
the resources involved and the types of locks acquired and requested. For this kind of information, SQL Server provides
Trace Flag 1222 (this flag supersedes 1204, which was frequently used in earlier versions of SQL Server.)
DBCCTRACEON(1222,
-1);
GO
With this flag enabled, SQL Server will provide output in the form of a deadlock graph, showing the executing statements
for each session, at the time of the deadlock; these are the statements that were blocked and so formed the conflict or cycle that led to the deadlock.
Be aware that it is rarely possible to guarantee that deadlocks will never occur. Tuning for deadlocks
primarily involves minimizing the likelihood of their occurrence. Most of the techniques for minimizing the occurrence of deadlocks are similar to the general techniques for minimizing blocking problems.

Dead lock error while updating data into cube

We have a scenario of daily truncate and upload of data into cube and volumes arrive @ 2 million per day.We have Parallel process setting (psa and data targets in parallel) in infopackage setting to speed up the data load process.This entire process runs thru process chain.
We are facing dead lock issue everyday.How to avoid this ?
In general dead lock occurs because of degenerated indexes if the volumes are very high. so my question is does deletion of Indexes of the cube everyday along with 'deletion of data target content' process help to avoiding dead lock ?
Also observed is updation of values into one infoobject is taking longer time approx 3 mins for each data packet.That infoobject is placed in dimension and defined it as line item as the volumes are very high for that specific object.
so this is over all scenario !!
two things :
1) will deletion of indexes and recreation help to avoid dead lock ?
2) any idea why the insertion into the infoobject is taking longer time (there is a direct read on sid table of that object while observed in sql statement).
Regards.

hello,
1) will deletion of indexes and recreation help to avoid dead lock ?
Ans:
To avoid this problem, we need to drop the indexes of the cube before uploading the data.and rebuild the indexes...
Also,
just find out in SM12 which is the process which is causing lock.... Delete that.
find out the process in SM66 which is running for a very long time.Stop this process.
Check the transaction SM50 for the number of processes available in the system. If they are not adequate, you have to increase them with the help of basis team
2) any idea why the insertion into the infoobject is taking longer time (there is a direct read on sid table of that object while observed in sql statement).
Ans:
Lie item dimension is one of the ways to improve data load as well as query performance by eliminationg the need for dimensin table. So while loading/reading, one less table to deal with..
Check in the transformation mapping of that chs, it any rouitne/formula is written.If so, this can lead to more time for processing that IO.
Storing mass data in InfoCubes at document level is generally not recommended because when data is loaded, a huge SID table is created for the document number line-item dimension.
check if your IO is similar to doc no...

Dhanya

I want TSPITR ,during this operation i faced this deadlock error.
Before that we faced roll backsegment error for that we applied follwing workaround .
If i applied follwing workaround before every backup and restore .i didn't get any error .all things went successful.
spool /tmp/Createtest.log
connect / as sysdba
REM Perform startup in case we are still down
ALTER SYSTEM SET PROCESSES=500 SCOPE=SPFILE;
SHUT IMMEDIATE;
STARTUP MOUNT EXCLUSIVE;
ALTER DATABASE ARCHIVELOG;
ARCHIVE LOG START;
ALTER DATABASE OPEN;
connECT / as sysdba;
alter system set undo_management = MANUAL scope=spfile;
shutdown immediate;
startup;
Connect / as sysdba;
DROP TABLE TEST123;
create table test123 (t1 number, t2 varchar2(10));
begin
for i in 1.. 300000 loop
insert into test values (i,'AAAAAAAAAA');
end loop;
end;
delete test123;
commit;
alter system set undo_management = auto scope=spfile;
shutdown immediate ;
startup ;
The above workaround we applied before creating tablespace and datafile ,after that we face some dead lock error while restore TSPITR .Did you need any more information

Does dropping bitmap index and creation of b- index cause any dead locks

Does dropping a bitmap index on table which is being used continuously for DML operations and creation of b- index cause any dead locks on a table
in oracle 10g database
( 10.1.0.4.0 - 64bi).
we have seen alert log file which has dead lock occurrence.. would index change/re-creation resulted dead lock or some other reason?
Could you please give us info or help us on this.. thanks in advance..

Bitmap indexes can be the cause of deadlocks on busy systems.
Dropping indexes may cause some locking.
Creating indexes may cause some locking.
You haven't given any traces or scripts or lock information, so difficult to say which one (if any) was the cause of your deadlocks.
It would be better to do this activity when the system is not busy.

Dead Locks

Gurus,
Please clarify me the three questions which I am posting below
1) What's the deadlock situation ? How oracle treats the dead lock situation
2) Disadvantages of having index
3) I have two tables A and B .. In table A, I have two columns (say col1, col2) .. Col1 is a primary key column .. In table B, I have two columns (say col3, col4) .. Col3 is a primary key column .. Col2 of A has a referrential integrity to Col3 of B ..And Col4 of B has a referrential integrity to col2 of A .. Now if I am inserting a values in table A ...it is showing error "parent value doesnt exist" .. like wise, if I am inserting values in table B, the above mentioned error is comming ..
How to overcome this error
Please advice
Regards

Hi.
1) A dead lock is a situation where two or more sessions acquire locks which then prevent each other from moving on. ie session one updates a row aaa in a table and session two updates row bbb (no commits). Session one then attempts to update row bbb and session two attempts to update row aaa and both wait for the locks to clear (default behaviour). Oracle monitors for these situations and will automatically kill one of the sessions and allow the other to complete.
2) Indexes are used to speed up access to data in the database and if associated with a Primary or Unique Key, enforce uniqueness. They have the disadvantages of taking up space and slowing down updates and inserts.
3) This is not a deadlock. It is a circular reference. You cannot insert into one table because the other table is expected to have a parent value and vice versa. From a data modelling point of view a circular reference is unsupportable and meaningless. Like trying to be your father's son and your father's father at the same time.

Dead Lock occured while Sync index in oracle text

Hi All,
We are facing dead lock issue which syncing the oracle text index . The index is built on the local partitioned table and the sync index has the parameters below,
parallel - 4
memory - 20M
the error message is,
System error: Plsql job execution is failed with
error code -20000 and error message ORA-20000: Oracle Text error: DRG-50610:

Thanks in advance.

How many occurrences of XYZ are there per XML document ?
If there are more than one, then obviously you cannot create such an index on it.
In this case, you'll need an XMLIndex, unstructured or structured, depending on the type of queries you want to run.
If there's only one occurrence, could you post a sample document and your db version?
Thanks.

Dead Lock

Hi ,
when doing some work in biw side, i got a run time error of Dead lock.

ORA-00060 dead lock happen on R12 demo database

We have EBS R12 (12.0.4) on Redhat Linux system when I check alert.log file and found demo database (VIS) have ORA-00060 dead lock. The dead lock happen on statement:
UPDATE FND_CONCURRENT_REQUESTS SET PP_END_DATE = SYSDATE, POST_REQUEST_STATUS = 'E' WHERE REQUEST_ID = :B1
Do I need do anthing relate to this ORA- error or just ignore it?
Thanks.

Thank you for answer. I checked CM log and did NOT find any error.
I also read document 153717.1 and compare FND_CONCURRENT_REQUESTS table definition. The initial number of trnasaction is 10 and max is 255. I try to use OEM to change "initial transaction number" and it don't allow to.
Any ideal???

Dead lock handling

Hi
I am running a little test that runs two threads that update the same table. Each thread tries to update several documents in the within a single transaction. The update is done by retrieving the document, modifying it, adding the updated document and deleting the existing document.
I have enable dead lock detection and when a dead lock exception is thrown I abort the current transaction.
However after a few iteration, deleteDocument causes a core dump and DBXML prints to stderr : "Previous deadlock return not resolved".
Is there anything else to resolve when a dead lock occurs other than abort the transaction?
This is the relevant stack trace:
