Update rule dead lock
I need to reload an ODS to an infocube. I've erased the whole infocube (fact table and dimensions) and then i launched init with all data from ODS to infocube. All informations are getting stuck at the level of update rules. It ends after a while wih TIME OUT error.
I've verified in Runtime Errors(st22) and the loading stops at an update rule for Material Group:
SELECT MATL_GROUP FROM /BI0/PMATERIAL INTO RESULT WHERE MATERIAL =
COMM_STRUCTURE-MATERIAL.
ENDSELECT.
I've commented the routine and it loads withou any problem.. But I really need the material group in the infocube. What could I do.
Please help... I will assingn valuable points.
Thank you and Merry Christmas,
Gabriel
Load your material master from the source system and the Material Group is generally the navigational attribute of the 0MATERIAL. Hence you just have to switch on the Navigational attribute in your InfoCube.
Hope it solves your problem.

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...

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.

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.

Hello,
In our R/3 Enterprise 4.7 Production system running on Windows NT/MSSQL, I saw update errors in t-code SM13.
Error details:
Date : 07/19/2009
No. of errors : 24
All errors are for background user BATCH-ID
Function Module : RKE_WRITE_ACT_LINE_ITEM_OP01
Status : DB dead lock during update
SM12 doesnt have any locks currently, not sure about status when these update errors occured.
I didnt find any SAPnotes related to this F-module or similar.
Can you please tell whether it is a serious issue and how to handle such errors?
Regards,
RoshanHi,
can u please let us know how many time u have seen this error in SM13. Also from how many days.
If its only once u have seen, then no need to worry.
Function Module : RKE_WRITE_ACT_LINE_ITEM_OP01
Status : DB dead lock during update
From above lines its clear that, Function Module : RKE_WRITE_ACT_LINE_ITEM_OP01 was locked, so the update has failed to access that module. Since it had faield to update, so is the error in sm13 with reason DB dead lock during update.
Can u please refer to the logs in SM21 and also to the trace files(of related work process) related to the same error(red color errors), Try to analyze from there, If u find any difficulties in doing so. Paste the same here along with ur system verion/DB/OS/Patch level

hI,
What are dead locks in BWHi ,
The concept of dead lock is as similar as in Oracle. If Process P1 is using resource A (locked by P1)) and waiting for B and Process P2is using resouce B(locked by P2) and waiting for resouceA. This creates dead lock as both can not proceed further.
In BW deadlock usually occur in delta load. As, far as my observance deadlock usually occurs during processing of update rules. This may be because more than one package will be processing same record as in delta load, data moves from changelog of below level to next level.

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?

I look forward to the suggestions to get the issue resolved. Your input is much appreciated.
Thanks,
Keshava.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. -
Hi,
I am transporting update rules for a Cube.
The InfoSource has been generated from a DSO and created update rules to the above said Cube.
In the transports I am getting the below error.

The InfoCube(It is already there in Q apd P) has been locked in a different user transport as he added a field to it and not yet transported.
Is this the problem?
Thans in advance..

Indira SRHi indira,
make neccessary changes to the request if u created earlier i.e u can delete the original request or change the discrption to "Dont delete" and release it, if u unable to delete each task in that particular request.
Second step is activate all the infosources and cubes and Update rules.
Then create transport request individually i.e One for IS and One IC and another for Update rules..It would be easier to trace in case of any error.
Release the requests 4m DEV, and important thing is import these requests in Q or P in hierachiel manner i.e
1. IS
2. IC
and the Update rules request. -
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
RegardsHi.
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.

Adobe flash updater appears to lock user profile files in Windows 7
Hello All,
I don't own any Adobe products, but I wanted to put this up so that others who run into this issue can find it, and hopefully Adobe will look into it if it's common.
This evening, I had just restarted my computer (Windows 7 RC), and after an usually long load time, I found myself loading into a profile other than my own. Windows informed me that it has been unable to access my user profile and so had booted me into a temporary profile. I noticed that the reason for being unable to access the profile was that it was being accessed (locked) by another program. I rebooted.
This time when I logged in, I was taken to my own profile, but before it loaded, I received a message from windows stating that it has been unable to open the user profile, and at the same time I saw a prompt from the Adobe Updater asking me if I wanted to upgrade to the next version of Adobe Flash. After closing the dialogs, my profile contained everything for my desktop, but my windows settings appeared to have all been disabled (meaning Windows Aero was turned off and everything looked...odd--like an older version of windows squeezed into the updated Windows 7 interface).
Taking a guess that the prompt from the Adobe updater may have been responsible for locking the profile while it was awaiting a response (somehow I guess it was running BEFORE windows loaded the user profile), I uninstalled all my adobe products and rebooted.
Issue solved. Presumably, installing the update when you first see the prompt and not waiting for another time after a reboot would also bypass this issue.
So it appears that the Update prompt locks the Windows user profile in Windows 7, which causes a problem because (maybe only on machines that don't auto login?) it appears to run before the profile loads: so it has a user profile file locked waiting for a response from the user, which can't come because the profile hasn't been loaded by Windows (so the user can't see the prompt), but Windows can't load the profile because the file is locked...sort of a soft dead lock (since I was sort of able to get in eventually).
Wanted to get this out, and was also wondering if anyone else has seen this issue.
Cheers,

Sessions were still active eventhough Dead lock detected
Hi all,
Yesterday I saw very odd oracle behaviour.When oracle finds Dead lock it should kill those sessions automatically.In my case those two sessions were still trying to run the same update command and were casuing dead locks again and again for 1 Hour.I had to kill those sessions manually to avoid these dea lock.
How can those sessions were still trying eventhough dead lock detected and causing deadlocks.My logfile filled with this dead lock error.When I killed those sesions it end up with snap shot too old error.
Please suggest me
Thankshi
just ROLLBACK or COMMIT any one session. you will out of dead lock.
and one more thing is in dead lock situation the sessions were not terminated
and session wating for releasing locks aquire by another session
try this one if not work plz reply
have a nice time
best luck -
Hi,
I posted a question in the OCCI forum (Subscribing/unsubscribing call is blocking (lock?) but now I'm starting to suspect that this is a general AQ problem.
We have a AQ queue with multiple subscribers, where the subscribing clients are implemented in OCI/OCCI. At the startup of the client program, we subscribe to the queue trough a stored procedure, and creates a callback in the OCCI implementation of the client.
The problem is that sometimes the subscription query / callback creation seems to block. Could this be because a lock has been put on the subscriber/queue? There is no explicit locking in our code, as far as I know.
The stored procedure for subscribing basically does this:
DBMS_AQADM.ADD_SUBSCRIBER(queue_name => v_queue_name,
subscriber => subscriber,
rule => p_rule);
I'm an experienced programmer, but not too familiar with Oracle/AQ, so it would be great if someone could point me in the right direction of debugging this. I have access to Toad.
EDIT: We are running three threads simultanously, all calling add_subscriber. Could this be a problem, creating some sort of deadlock?
Thanks,
SverreHi,
do the clients have the same subcription name?
In the documentation see this link:
http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10785/jm_create.htm#i1005628
EDIT (Sorry i assumed that you use JMS ;-(
Can you tell me, what is the statement which shows up in the dbconsole in the top activity when the (dead)lock appears? (I hope you use 10g)

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.

When we are using our oracle application, our session hang every time the user update records. the DBA said that we have a dead lock error... the only thing he did is to reset sa database every time we in counter this problem. but we have this error every day, and i don't have an ideal regarding what is dead lock.
you don't have a deadlock problem, because a deadlock will be "solved" as oracle simply kills the blocking session and rollbacks the changes.He is right. you might have blocking problem not dead lock problem. Find out the blocker and waiter and kill the blocker session.
Following query would give you an idea about who is blocking and who is waiting for :
select /*+ ordered */
a.sid blocker_sid,
-- c.sql_text,
a.username blocker_username,
a.serial#,
-- a.logon_time,
b.type,
b.lmode mode_held,
b.ctime time_held,
c.sid waiter_sid,
c.request request_mode,
c.ctime time_waited
from v$lock b, v$enqueue_lock c, v$session a, v$sqltext c
where c.address=a.prev_sql_addr and
a.sid = b.sid
and b.id1 = c.id1(+)
and b.id2 = c.id2(+)
and c.type(+) = 'TX'
and b.type = 'TX'
and b.block = 1
order by time_held, time_waited
Look for blocker_id and waiter_id. If possible, kill blocker using following command.
select sid,serial# from v$session where sid = blocker_sid;
alter system kill session 'sid,serial#'';

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??? -
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:

Perhaps you should have used the -p or --strip option?
