Toplink locking oracle tables?

Does toplink ever issues a "Lock Table" or "Select xxx From xxx FOR UPDATE"?
I'm getting a oracle error: ORA-00060: deadlock detected while waiting for resource
When I query the v$locks table I can see
SID Type LMODE
252 TM 3
From what I've read this is a table lock. Is TM LMODE 3 a table lock? Or just a row exclusive lock?
http://rahulagarwal.wordpress.com/2006/03/27/locking-in-oracle-dml-locks/

TopLink never issues a Lock table but can issue a SELECT ... FOR UPDATE. The pessimistic locking SELECT ... FOR UPDATE requires the developer to configure its use on a query or through the UnitOfWork API.

Locking oracle table data

I have a 3 tables which contains some crucial accounting data. Now I want to lock the data in those tables for 1 financial year(within a period). Locking data refers to not being able to insert, update or delete the data. But i need to view them time to time and my crystal report use that table too. I can restrict the user in my application. But accidently it may happen sometime. You know sql, a single query can modify or delete the whole table. I just want to protect the data even if any accidents happened.
Can I really do that.
My oracle version is 8i.
Thanks in advance

1. If you are using 11g Release 1 then you can :
alter table table1 read only;
alter table table1 read write;
2. Trigger
Source:http://www.devx.com/tips/Tip/29396
Despite that limitation, you can simulate a read-only table by simply preventing all table modifications using a trigger. To do that, create a trigger as follows.
SQL> create or replace trigger emp_sal_read_only
2 before insert or update or delete
3 on emp_sal_tbl
4 begin
5 raise_application_error (-20001, 'Table EMP_SAL_TBL is read only,
You cannot make changes to the data.');
6 end;
7 /
Trigger created.
Here's a test command that tries to alter the data, and the resulting output:
SQL> DELETE FROM EMP_SAL_TBL;
DELETE FROM EMP_SAL_TBL
ERROR at line 1:
ORA-20001: Table EMP_SAL_TBL is read only, You cannot make changes to the data.
ORA-06512: at "SRIDHAR.EMP_SAL_READ_ONLY", line 2
ORA-04088: error during execution of trigger 'SRIDHAR.EMP_SAL_READ_ONLY'

Lock a table with toplink

Hello
I would like to lock a table with a toplink instruction (ie select for update).
How to lock the data ?
Thank in advance.

You can think of using pessimistic locking if you are wanting SELECT for UPDATE.
Following documentation will help you in this regard -
- http://oraclesvca2.oracle.com/docs/cd/B14099_19/web.1012/b15901/dataaccs008.htm
There is a section on pessimistic locking in that URL.

Using OleDbDataAdapter Update with InsertCommands and getting blocking locks on Oracle table

The following code snippet shows the use of OleDbDataAdapter with InsertCommands. This code is producing many inserts on the Oracle table and is now suffering from contention... all on the same table. How does the OleDbDataAdapter produce
inserts from a dataset... what characteristics do these inserts inherent in terms of batch behavior... or do they naturally contend for the same resource.
oc.Open();
for (int i = 0; i < xImageId.Count; i++)
// Create the oracle adapter using a SQL which will not return any actual rows just the structure
OleDbDataAdapter da =
   new OleDbDataAdapter("SELECT BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, " +
   "DIRECT_INVOICING, EXCLUDE_FLG, DTTM_CREATED, DTTM_MODIFIED, IMAGE_DATA, PROCESS_INSTANCE FROM sysadm.PS_RI_INV_PDF_MERG WHERE 1 = 2", oc);
// Create a data set
DataSet ds = new DataSet("documents");
da.Fill(ds, "documents");
// Loop through invoices and write to oracle
string[] sInvoices = invoiceNumber.Split(',');
foreach (string sInvoice in sInvoices)
    // Create a data set row
    DataRow dr = ds.Tables["documents"].NewRow();
    ... map the data
    // Populate the dataset
    ds.Tables["documents"].Rows.Add(dr);
// Create the insert command
string insertCommandText =
    "INSERT /*+ append */ INTO PS_table " +
    "(SEQ_NBR, BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, DIRECT_INVOICING, " +
    "EXCLUDE_FLG, DTTM_CREATED, DTTM_MODIFIED, IMAGE_DATA, PROCESS_INSTANCE) " +
    "VALUES (INV.nextval, :BUSINESS_UNIT, :INVOICE, :ASSIGNMENT_ID, :END_DT, :RI_TIMECARD_ID, :IMAGE_ID, :FILENAME, " +
    ":BARCODE_LABEL_ID, :DIRECT_INVOICING, :EXCLUDE_FLG, :DTTM_CREATED, :DTTM_MODIFIED, :IMAGE_DATA, :PROCESS_INSTANCE)";
// Add the insert command to the data adapter
da.InsertCommand = new OleDbCommand(insertCommandText);
da.InsertCommand.Connection = oc;
// Add the params to the insert
da.InsertCommand.Parameters.Add(":BUSINESS_UNIT", OleDbType.VarChar, 5, "BUSINESS_UNIT");
da.InsertCommand.Parameters.Add(":INVOICE", OleDbType.VarChar, 22, "INVOICE");

// Update the table

Here is what Oracle is showing as blocking locks and the SQL that has been identified with each of the SIDS. Not sure why there is contention. There are no triggers or joined tables in this piece of code.
Here is the SQL all of the SIDs below are running:

I have tried this out in the EA release of JDev, and have reproduced the problem you reported. However, trying out the latest development build, the problem does not occur, so this bug has been fixed. You'll pick up this fix when we next release the software on OTN.

Deadlock issue in while inserting in oracle table.

I have written a procedure which copy data in to oracle tables.Other user can also start inserting in that table so to prevent these intervention.
i have applied locks on these two tables and assume that my procedure will wait for other users to finish and it will apply lock on the tables and other users will now wait till this procedure finishes.
My Procedure looks like:--
lock table table1 in exclusive mode;
lock table table2 in exclusive mode;
update table1 set where rownum < x;
forall .....insert in table 2.
commit;
EXCEPTION
WHEN OTHERS THEN
dbms_printline(SQLERRM)
commit;
END;
But my problem is i am still receiving oracle error as below and the above procedure fails in between:-
ORA-00060: deadlock detected while waiting for resource
Any hint ??
Can we get this error if i execute a SELECT statement on some table which is not locked by me and some other other is updating/deletig/inserting in that table ?
*Select statement is without update clause.

Any hint ??But if you successfully lock TABLE1 (in session #1) and another session (session #2) is holding a lock against TABLE2 (say it's currently updating a row) then session #1 has to wait when you issue the Lock table command for table2. So session #1 is waiting, and then session #2 tries to do ANY modification to TABLE1 (which session #1 still has locked, and is still waiting to obtain the lock on TABLE2)... whamo, deadlock.

*Select statement is without update clause.No, writes (and locks) do not block reads. So a simple select statement (unless you issued a FOR UPDATE clause) would not cause this issue.
What does your actual code look like, and what are you actually attempting to do? Why do you think you need to lock the tables, is this a one time operation, a continual operation of the system? Please explain in much more detail what you've got going on here.

ORA-00054 error when loading Oracle table using Data Services

Hello,
we are facing ORA-00054 error when loading Oracle table using BO Data services
(Oracle 10g database, BODS Xi 3.2 SP3)
Test Job performs
1- truncate table
2- load table (tested in standard and bulk load modes)
Scenario when issue happens is:
1- Run loading Job
2- Job end in error for any Oracle data base error
3- When re-running the same Job, Job fails with following error
ORA-00054: resource busy and acquire with NOWAIT specified
It seems after first failure, Oracle session for loading the table stays active and locks the table.
To be able to rerun the Job, we are forced need to kill Oracle session manually to be able to run the Job again.
Expected behaviour would be : on error rollback modifications made on table and BODS stops Oracle session in a clean way.
Can somebody tell me / or point me to any BODS best practice about Oracle error handling to prevent such case?
Thanks in advance
Paul-Marie

the ora-0054 can occure depending how the job failed before. If this occures you will need the DBA to release the lock on the table in question
Or
AL_Engine.exe on The server it creates the Lock. Need to Kill Them. Or stop it..
This Problem Occurs when we select The Bulkloading Option in orclae We also faced the same issue,Our admin has Killed the session. Then everything alright.

Shrink Oracle Table after Deletion

A few database tables are very big. An Oracle table still holds the disk space occupied by deleted records according to http://stackoverflow.com/questions/6540546/oracle-10g-table-size-after-deletion-of-multiple-rows. Re: shrink table after delete teaches the following commands to release the idle space from the table.
ALTER TABLE TABLE1 DEALLOCATE UNUSED;
ALTER TABLE TABLE1 ENABLE ROW MOVEMENT;
ALTER TABLE TABLE1 SHRINK SPACE;
ALTER TABLE TABLE1 MOVE;
1. Are the commands feasible?
2. Are they safe?
3. What will be the impacts of running the commands?
4. Is there any other workable safe approach shrinking a table?

Hi,
I advise using shrink table operation.
The tablespace which belong to your table must be in ASSM (Automatic segment space management) to use shrink.
Shrink is safe but you need to run two commands :
1)ALTER TABLE TABLE1 SHRINK SPACE COMPACT; (This is long operation which moves data, but can be done online)
2)ALTER TABLE TABLE1 SHRINK SPACE; (this is quick if you run SHRINK SPACE COMPACT before, it only shift the High Water Mark. Be carreful if you don't run SHRINK SPACE COMPACT before your table will be locked for a long time)
Another point, is that execution plans are calculed using the HWM so SHRINK the table (The 2nd command) will invalidate all the cursors in shared pool where the table is in. So execution plan need to be recalculated (often not a problem).
Regards,

Problem related to locking the table

Hi all,
i am facing a problem while applying locks on the oracle table.my intention is stop the accessing of table to other users, if the table is locked by one user.
for this i wrote the code as follows
Class.forName("oracle.jdbc.driver.OracleDriver"); con = DriverManager.getConnection("jdbc:oracle:thin:@192.168.2.123:1521:xe", "root", "paridb"); con.setAutoCommit(false); System.out.println("Successfully connected to " + "Oracle server using TCP/IP..."); String lock="lock table report@xe in exclusive mode";-------------------------------------->1 query to lock the table Statement stmt1=con.createStatement(); stmt1.executeUpdate(lock); System.out.println("lock is applied"); Statement stmt=con.createStatement(); for(int i=0;i<6;i++) { sql="insert into report values(1921682123,'device','host')"; stmt.executeUpdate(sql); }
after locking i inserted some data into table, after insertion i am not commiting it because if i commit,the lock will be release.next i am trying to insert data into that table from another system,acutually the data don't insert.but data is inserted. how it is happening like that ??
in another scenario, if execute the locking query on the database directly then trying to insert into database through java application, at that time it is not giving permission to access table.
plz guide me
thanks&regards,
nagaraju

Hi! Thank you so much for your reply. Yes, I´m using ADF. I attach you the iterator´definition from the page definition:
<iterator id="MovimientosCtbView3Iterator" RangeSize="10"
Binds="MovimientosCtbView3" DataControl="AppModuleDataControl"/>
If I set the RangeSize to 11, the problem is solved, but my project manager want to find out why this situation happens with RangeSize=10.
Thank you so much and sorry for bothering you

Lock the table by user with grant only for select

It is possible that the user has rights only for SELECT, do not lock the table? Now, where do "SELECT * FROM table FOR UPDATE", does not make the change, but it locks the entire table, and another user to get into it.

Renaming Oracle Tables in Production

If you need to rename Oracle tables in Production, then which process is most effective:
A.
LOCK TABLE xxx IN EXCLUSIVE MODE
RENAME xxxTO new_name;
Table renamed.
B. dbms_redefinition
C. other ...
THANK YOU !!

All we can say is that dmbs_redefinition is an option to consider. Only the OP knows his environment, what kind of window the work will have to be done in, and the timing issues between the renames and moving in new code. Such as in the case where you need the new object names in place to perform java compiles to move in new classes.
At my current job we would take a window and shut the database down, bring it up in restricted mode, perform the renames of the tables (and associated indexes for standard purposes), move the code into place, and then test. Full testing might require unrestricting the system or we might be able to just grant restricted session to a few users. Once we are satisified we would fire up our daemon processes and then release the batch schedule.

Best Practice to fetch SQL Server data and Insert into Oracle Tables

Hello,
I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
We do not have any database dblinks from oracle to sqlserver and vice versa.
Any help is highly appreciable?
Thanks

Well, that's easy:
use a TimerTask to do the following every half an hour:
- open a connection to sql server
- open two connections to the oracle databases
- for each row you read from the sql server, do the inserts into the oracle databases
- commit
- close all connections

Insert /delete data from SAP Z table to Oracle table and opposite

Hi,
Can u help me write this FM from the SAP side?
So, I have two tables ZTABLE in SAP and Oracle table ORAC.
Let's put three columns in each of them, for example
TEL1
TEL2
ADRESS
NAME
where TEL field is primary from ZTABLE to ORAC...
(in FM there shoud be abap code for writing data in ZTABLE after we press some pushbutton made in sap screen painter..)
for example, when we write new record in ZTABLE
00
112233
Street 4
Name1
this data shoud be inserted in Oracle table ORAC.
when we write new record in Oracle table for example
01
445566
New Street
Name2
this data shoud be inserted in ZTABLE.
Field TEL1 can be only of two values 01 or 02, other combination is not valid...
I must have all data from Oracle table ORAC in ZTABLE and opposite.
It should be the same scenario for DELETE...
And this communication should be online between sap and table in oracle database...
Can u help me from sap side? and give idea how to configure on oracle side??
Thanks a lot,
Nihad

I dont know if we can directly connect to a oracle database ( wait for the answers from others on this )
but in XI we have the JDBC adaptor to insert and retrieve data.
so for the outbound from SAP the flow can be something like this (with XI in landscape):
1) You have a screen to maintain a new entry / delete an entry
2) On save , this record gets saved or deleted from the Ztable in SAP
3)) In the same screen you can call a proxy class-method (generated using SPROXY transaction ) to send the record to XI.
4) XI to format it and insert into the oracle table

<field name="ord_qty">
<string>10</string>
<string>50</string>
</field>
</recordset>
</var>
