Lock table

My archival jobs continuously fails because of Lock table overflow even after increasing parameter enque/table_size and then bounced.
But in SM12 No lock entries found
Under SM12 EXTRAS -> STATISTICS OR DIAGONOSTIICS are inactive
Job logs as below...
Job started
Step 001 started (program ZRJJARC20, variant CLL4, user ID MINIO)

Lock table overflow
Job cancelled after system exception ERROR_MESSAGE

Lock tables when load data

Are there any way to lock tables when i insert data with SQL*Loader? or oracle do it for me automatically??
how can i do this?
Thanks a lot for your help

Are there any problem if in the middle of my load (and commits) an user update o query data ?The only problem that I see is that you may run short of undo space (rollback segment space) if your undo space is limited and the user is running a long SELECT query for example: but this problem would only trigger ORA-1555 for the SELECT query or (less likely since you have several COMMIT) ORA-16XX because load transaction would not find enough undo space.
Data is not visible to other sessions, unless, the session which is loading data, commits it. That's the way Oracle handle the read committed isolation level for transaction.
See http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96524/c21cnsis.htm#2689
Or what happens if when i want to insert data someone has busy the table?You will get blocked if you try to insert data that has the same primary key as a row being inserted by a concurrent transaction.

System error: Unable to lock table/view V_T077K_M

Hi,
Not able to work on field selection (OMSG) i am getting an error "System error: Unable to lock table/view V_T077K_M" checked in SM 12 also, but dint get there anything.
please cud you help me in this regard,

contact your basis team, there might be an overflow of the lock table because of mass changes from other users (even for other tables)

Timeout when inserting row in a locked table

How can I set the timeout before an INSERT statement fails with error ORA-02049 (timeout: distributed transaction waiting for lock) when the entire table has been lock with LOCK TABLE .
Documentation says to modify DISTRIBUTED_LOCK_TIMEOUT parameter, but it is obsolete in Oracle 8i.
Any idea ???

You could set an alarm() in a signal. Then on return (for whatever reason) you clear the alarm, inspect the return code of the sql execute call and determine what happened (i.e. did the transaction completed or did the alarm get you).
Hope it helps.

IDOC Receiver Adapter, getting Lock Table Overflow to CRM System

Hello SDN!!!
This scenario is for PI to process a file and send to CRM via IDOC. The IDOCu2019s are only being created and not processed until later.
Problem: I am getting a Lock Table Overflow error in method IDOC_INBOUND_ASYNCHRONOUS via sm58 in PI which points to the CRM box.
I have been searching many forums and every solution seems to indicate increasing the lock table, the problem with that solution is we are currently trying to create (not process yet) 80000 IDOCu2019s. This would allocate too much for the lock table.
So my question is this, Shouldnu2019t the lock be released when the IDOC gets created or none the less when a packet of IDOCu2019s via content management (breaking up the file in 1000 increments) finish. The lock table in CRM keeps increasing until all rows from the file, sent via IDOC adapter in 80 messages with 1000 IDOCu2019s per messagein the table are complete (80 separate messages in sxmb_moni).
Background:
IDOC was imported, changed to include unbounded and reimported.
Content Management breaks the file into 80 different segments, thus creating 80 distinct mappings with distinct MessageIdu2019s.
80 IDOC packets are sent to CRM, via IDOC adapter and sm58.
TCODE sm12 in CRM shows the table to keep growing and locks not released until full message is complete.
Any help would be appreciated
Cheers
Devlin

The only way to process the IDOCs in this case is by increasing the "enque/table_size" parameter in order to create the required IDOCs. You can increase the value for this parameter up to 102400 (beyond that can cause performance issues). Since you need to handle 80000, this shouldn't be an issue.
Please refer to the notes below for more information about the lock queue overflow and management.

How to Create an Alert on a V$Lock Table

Hi Gurus,
Can anyone help me out on. how to create an event alert on locks table (V$LOCK). so that whenever a table is locked , i can send the email notificaiton to the user regarding the locking history.
any approach is highly appreciable.

Hi,
as event alerts in eBS in fact are based on trigger concept and it's not allowed to
create triggers on objects owned by SYS i don't think that this will be possible.

Enqueue Replication Server - Lock Table Size

Note : I think I had posted it wrongly under ABAP Development, hence request moderator to kindly delete this post. Thanks
Dear Experts,
If Enqueue Replication server is configured, can you tell me how to check the Lock Table size value, which we set using profile parameter enque/table_size.
If enque server is configured in the same host as CI, it can be checked using
ST02 --> Detail Analysis Menu --> Storage --> Shared Memory Detail --> Enque Table
As it is a Standalone Enqueue Server, I don't know where to check this value.
Thanking you in anticipation.

MM42 change material, split valuation at batch level, M301, locking table

Dear All,
I'm working on ECC 6.0 retail and I have activated split valuation at batch level. Now in MBEW for this specific material I have almost 14.400 entries.
If I try to change some material data (MM42) I receive an error message M3021 A system error has occurred while locking and then Lock table overflow.
I used SM12 to see the table (while MM42 is still running) and it seems that MBEW is the problem.
What should I do? For any material modification the system has to modify every entry in MBEW? Is there any possibility to skip this?
Thank you.

Hi,
Symptom
Key word: Enqueue
FM: A system error has occurred in the block handler
Message in the syslog: lock table overflowed
Other terms
M3021 MM02 F5 288 F5288 FBRA
Reason and Prerequisites
The lock table has overflowed.
Cause 1: Dimensions of the lock table are too small
Cause 2: The update lags far behind or has shut down completely, so that the lock entries of the update requests that are not yet updated cause the lock table to overflow.
Cause 3: Poor design of the application programs. A lock is issued for each object in an application program, for example a collective run with many objects.
Solution
Determine the cause:
SM12 -> Goto -> Diagnosis (old)
SM12 -> Extras -> Diagnosis (new)
checks the effectiveness of the lock management
SM12 -> Goto -> Diagnosis in update (old)
SM12 -> Extras -> Diagnosis in update (new)
checks the effectiveness of the lock management in conjunction with updates
SM12 -> OkCode TEST -> Error handling -> Statistics (old, only in the enqueue server)
SM12 -> Extras -> Statistics (new)
shows the statistics of the lock management, including the previous maximum fill levels (peak usage) of the partial tables in the lock table
If the owner table overflows, cause 2 generally applies.
In the alert monitor (RZ20), an overrunning of the (customizable) high-water marks is detected and displayed as an alert reason.
The size of the lock table can be set with the profile parameter u201Cenque/table_size =u201C. specifies the size of the lock table in kilobytes. The setting must be made in the profile of the enqueue server ( u2026_DVEBM.. ). The change only takes effect after the restart of the enqueue server.
The default size is 500 KB in the Rel 3.1x implementation of the enqueue table. The resulting sizes for the individual tables are:
Owner table: approx 560.
Name table: approx 560.
Entry table: approx 2240.
As of Rel 4.xx the new implementation of the lock table takes effect.
It can also be activated as described in note 75144 for the 3.1I kernel. The default size is 2000 KB. The resulting sizes for the individual tables are:
Owner table: approx 5400
Name table: approx 5400
Entry table: approx 5400
Example: with the
u201Cenque/table_size =32000u2033 profile parameter, the size of the enqueue table is set to 32000 KB. The tables can then have approx 40,000 entries.
Note that the above sizes and numbers depend on various factors such as the kernel release, patch number, platform, address length (32/64-bit), and character width (Ascii/Unicode). Use the statistics display in SM12 to check the actual capacity of the lock table.
If cause 2 applies, an enlargement of the lock table only delays the overflow of the lock table, but it cannot generally be avoided.
In this case you need to eliminate the update shutdown or accelerate the throughput of the update program using more update processes. Using CCMS (operation modes, see training BC120) the category of work processes can be switched at runtime, for example an interactive work process can be converted temporarily into an update process, to temporarily increase the throughput of the update.
For cause 3, you should consider a tuning of the task function. Instead of issuing a large number of individual locks, it may be better to use generic locks (wildcard) to block a complete subarea. This will also allow you to considerably improve the performance.

This error I have not faced. i will suggest you to check SWU3 transaction Code and check everything is configured. Also check SM12 and SM58. Also I will ask you to contact the Basis Guys related to this issue. Also check WF-BATCH is having all the authorization required. Try to replicate this from the system where Workflow is working.

Lock table overflow problem in transaction sm58

Hi ,
I have a file to idoc scenario.I am on xi 7.0 sp09.
I am posting about 10000 records at one time in a 1 mb file.
In idx5 i am able to idocs .
However in transaction SM58 I am seeing Lock table overflow error .
Regards ,
Deepak

Deepak,
Here you can solve the problem in two ways
1) increase the size of the lock table via parameter
enque/table_size
2) or increase the enque work processes from 1 to 2 or 3
via parameter rdisp/wp_no_enq
Please have a look on SAP Note: 928044.

Thanks

Hi.
The error could be due to following:
1. small size of lock table
2. a particular program sets a large no of locks
3. an update process hangs hence setting a large number of locks
please check below thread.

Command object locks table (TX)

Im having locking probmlems with ODP.NET. Im updating same table with many connections in many threads. I get table locks for hours (over 24 hours) and I cant find any timout to set. The CommandTimeout on the Command object is not implemented.
In the V$Lock table I can see two locks on the same table made by two session ids from the same computer.
Im using transactions on the Connection object.
How do I set a timout for the update so that the lock will dissapear?
String connString = "Data Source="     + dsn + ";"
          + "User ID="          + user + ";"
          + "Password="          + pwd;
OracleConnection conn = new OracleConnection(connString);
String sql = "UPDATE ABDATA2 SET ABNAVN='SOLNA STAD ' WHERE OBJID = -21805738";
OracleCommand command = new OracleCommand(sql, m_conn);
//command.CommandTimeout = 60000; Exists but not supported
command.ExecuteNonQuery();
Is there anyone who has a clue?

Hi Neo, thanks for responding;
I did not publish the report with saved data, and I'm not sure what you mean about appending the string value? Could you explain that part?
The parameter I created is only declared as a string with no default value with a name of "CodeTableName". I used the Create paramter button you have in the Command object window to make it.
I then added the parameter name to my SQL statement as listed above.
The actual code table names in the database is actually longer then what the parameter calls for. They all start with "TIBURON.ZZ_" and end with "_Codes". I didn't want the users to have to remember the full names so that's why the SQL statement shows those additional parts.
The report works perfect when I'm running this report from Crystal Reports 9 or CR11 itself. It's only when I upload the report to our web server that the users isn't provided a prompt to enter a parameter. They only have button labed "Run Report".
Any ideas?
Thanks,
Joe

Lock table overflow ???

Hi All,
We just installed a BW - IDES system, and in the process of activation of Business Content. There is a problem while activation, after the collection of CRM BI Content the system is giving following error, while installing the BI Content:
Message no. MC603
Diagnosis - This table overflowed when trying to enter SAP locks in the lock table.
System Response - The locks could not be set.
Procedure - Contact your system administrator. If this error occurs frequently, change the size of the profile parameter 'enque/table_size'. This parameter defines the size of the lock table in KByte.
Can someone please list down the steps to be taken to resolve the error or change the size of profile parameter.
Thanks & Regards,
Vikas Sharma

Hallo,
goto trans: /nRZ10 --> Select your instance profil and change or add parametere: 'enque/table_size' with the appropiate size. Best: Contact your BASIS people to change this parameter. And restart the system.
