Locked table by an insert

Hi,
some times an insert locks all the concerned table this transaction is always from web.
Any idea?
regards.

Here are some questions:
How can the table be locked, preventing DML by other users?
1) Is your application or users issuing SELECT FOR UPDATE commands
2) Is your application or users issuing LOCK TABLE IN EXCLUSIVE MODE
3) Is referential integrity being checked on foreign keys that do not have an index? If so, shared locks can be issued against the table limiting DML execution until the RI checks are complete.
Are you sure there is a table lock?
1) What are users waiting on when this problem occurs? Check v$session_wait for this. Also join v$session and v$lock on SID to see who has the lock(s) blocking the table.

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.

Few lock table questions ...

I have an app with Java + Oracle. I have a few tables which can be modified ( select, insert, up, del) by more than one user.
For ex
//---------- get info from database
SELECT a FROM A;
// later
SELECT b FROM B;
// --------- end
Q1). how can I make sure that after I select from A, no one modifies table B, until I select from B ?
Q2). If I have 3 tables and I have to insert some values, in all of them, how should I do this ? ( lock tables, put the insert * 3 into an transaction, release locks)
Q3). I know that jdbc-odbc isn't very good, but still, can I use it ?

Q1). how can I make sure that after I select from A,
no one modifies table B, until I select from B ?No one modifies table B in any way at all? While the user goes for a coffee break? Why would you want that?
Q2). If I have 3 tables and I have to insert some
values, in all of them, how should I do this ? ( lock
tables, put the insert * 3 into an transaction,
release locks)Just insert the records. You can put the three inserts in a transaction, if you need that, but there's no point in preventing other users from accessing the tables while you do that.
Database applications that use Oracle or other databases designed for large numbers of users rarely lock tables. If your design leads you into a place where you have to lock tables then you probably need to go back and fix your design so that it supports multiple users in a normal way.
Q3). I know that jdbc-odbc isn't very good, but
still, can I use it ?Sure. But Oracle comes with its own JDBC drivers so you don't need to.

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.

How to lock a table when i insert a row

hi, friends,
how to lock a table when i insert a row, then unlock the table

If you want to lock the whole table so that no-one else can do DML then you go LOCK TABLE <table> IN EXCLUSIVE MODE. This lock remains in force until you commit or rollback.
There are less powerful locking modes available, but you can look those up in the OTN online documentation.

Insert & Update while Locking tables

Update & Insert
Is it possible for me to insert a record and update 2 fields in another record, whil locking the database tables for the process to take place?
If so, how?
Thanks
Pete

I don't know which database server you are using. But in MySQL, you can do something like this:
<?php
function get_next_number( $field = 'id' )
 $id = 0;
 //Lock the table for write
 mysql_query('LOCK TABLES name_of_table WRITE');
 $sql = 'SELECT '.$field.' FROM name_of_table ORDER BY '.$field.' DESC LIMIT 1';
 $query = mysql_query($sql);
 if ( mysql_num_rows($query) > 0 )
 $row = mysql_fetch_row($query);
 //Get the $field value
 $id = $row[0];
 //Unlock tables
 mysql_query('UNLOCK TABLES');
 return ++$id;
?>
I didn't test this function, but the idea is that
Check if you are connected to MySQL server

Lock tables during partition exchange

Hi,
I want to do the following thing:
there are 9 partitioned tables (set A) and 9 non partitioned (set B).
There is a continuous dataflow into set A.And there is also a dependency between the nine flows within each transaction into set A (there is no dependency between different transactions.).
What I want is to exchange the nine partitions of set A with set B. This because I want to have a performance boost instead of copying the data from A into B.
I need to lock the tables of set A to make sure there is NO insertion of data into one of the tables of set A to avoid loss of dependency and thus loss of data.
I tried several things: lock tables, run autonomous transaction in which the exchange takes place, commit and unlock. But no success.
Who can help me to solve my problem: to lock all nine tables of set A and make sure the dependency remains consistent and no data gets lost?
Thanks.
jurgen

Why you are bothering about LOCKing the table,
you can goahead and do the exchange the table,
since, its ongoing activity, exchanged partition will be there till you merge, drop it.
if you found some more rows after exchange, then you can insert same into that table, or make another table.
Thanks

Locking tables

I am declaring and using the following cursor:
 CURSOR curCompany IS
 SELECT c.Company_ID, c.No_Employees
 FROM Company c
 WHERE (SELECT COUNT(*) FROM Student s
 WHERE s.Company_ID = c.Company_ID) > 0;I would like to include a FOR UPDATE OF Student.col to it so rows could be locked while they are being updated, but can't.
1) What is the best way of locking the table? I've been reading up on LOCK TABLE and am willing to use it but would like to hear what you guys have to say on this.
2) Is there an operator/function like EXISTS that would replace the sub-query in the WHERE clause?

I will tell you real world scenario:
 
Let suppose I have a table from I am getting series for my transaction depending on some parameter. 
 
Here at the time of pre insert in my form I use as follows:
 
Select series from table_name FOR UPDATE;
 
Offcourse I add in condition also.
 
At the time of post insert I release the lock as follows:
 
Update table_name SET series+1 with condition.
 
Why I am doing this because I want to make sure same number is not used by two transaction.

Lock Table and permit only SELECT-Statement

Hi all,
can I lock a Table and permit only SELECT-statements on a Table?
Regards
Leonid

Hi Kamal,
I would like to configure it in such a way that if I implement the SELECT statement, another user can't insert
a data into the table.
If it is possible, I even the LOCK would like in such a way to configure the fact that the entry of the user arrives into the buffer and if the table is unlocked, all lines from the Buffer again into the table.
I make it in such a way:
SQL Script script_test.sql:
set echo off
set verify off
set pagesize 0
set termout off
set heading off
set feedback off
lock table mytable in share row exclusive mode;
spool c:\Temp\script_info.lst
select id||'|'||dae||'|'||name||'|'||name1||'|'||hiredate
||'|'||street||'|'||nr||'|'||plznum||'|'||city
||'|'||email||'|'||telephon||'|'||cddfeas||'|'||number
||'|'||why||'|'||fgldwer||'|'||wahl||'|'||adress
||'|'||las
from mytable
where las is null
spool off
spool c:\Temp\select_from_all_tables.lst
select *
from all_tables
order by owner
spool off
spool c:\Temp\select1_from_all_tables.lst
select *
from all_tables
order by owner
spool off
update mytable
set las = 'x';
commit;
set feedback on
set heading on
set termout on
set pagesize 24
set verify on
set echo on
Afterwards I start another session:
insert into briefwahl
values(38,'11.06.2003 09:37','Test','Test','01.01.1990',
'Test','12','90000','Test',
'[email protected]','12345657','test','123',
'test','test','test','test',
null);
Then I go into the first session and start script. And I go immediately into the second session and do commit; And although I have the table closed, the new entries are spent also with spool into the .lst-File. Why, I do not understand. And in the table all lines become updated.

Lock table for update in adf

dear all ,
am using Jdeveloper 11.1.1.3 with oracle database 10g,
now what i need to do is when inserting a new row in one of my entities i need to lock the entire database table until the commit happen...
i'll explain to u why I need to do this,,, let say that the table x contains the following columns
x_pk number, ( which is the primary key )
x_serial number,
x_type varchar2 );
now am getting x_pk from a sequence on a database so its not a problem,
but for x_serial it needs to be serialized per x_type , now in oracle forms developer i used to do the following in per-insert trigger on the block level-->
lock table for update then selecting the max serial per the type then use it for setting the :x_serial that is in the same block...
now in ADF , i should do this in the do_dml when the operation==DML_INSERT but am not sure what to write and if it will be working same as it was in the form developer
thanks ,
Lama

Delta,
I wrote a [url http://stegemanoracle.wordpress.com/2006/03/15/using-updatable-views-with-adf/]blog post some time ago for an earlier version of JDeveloper that implemented some custom locking behaviour for EOs - perhaps you can adapt the technique there to your needs?

JDBC Lock Table

I am developing two java programs that are accessing an Oracle database using JDBC. The two programs are to access to same table simultaneously.
Is there a way I can use an sql LOCK TABLE command to lock a table while one program is writing to the table, and have the other program check for this Lock, and only proceed with updates on that table if the table is not locked? Would I need to have seperate database login IDs to accomplish this?
For example:
Program 1
stmt.executeUpdate("LOCK TABLE A");
//insert some records
con.commit();
Program 2
While ( TABLE A IS LOCKED)
//wait
Update table A

In future JDBC questions should be posted into the JDBC forum.
Whatever you are doing don't. Just use transactions. Figure out what kinds of transaction serialization your setup supports too.

Help needed with locking tables+Mysql

Hello!
I have a table "A" which is of kind "auto_increament" (field "A1")
When I do an insert in A I need to know the next "auto_increament" index because I have to encrypt that index into another field in A lets say this field is called A2.
I understand that I have to do like like I do below (the semantic syntax) but I dont know the java syntax for locking tables and getting the next "auto_increament" index. The "lock type" of the ttable should be so now one else can write to the table.
--------semantic syntax---------------
1) LOCK A
2) Get "next" index from A
3) Make an insert
4) UNLOCK A
Very greatful for help!

Lock table: How to notify others

Hi,
I 've created a Stored Procedure that inserts into a table.
The first and last statement of by BEGIN...END part of the stored procedure locks the table successfully.
BEGIN
      LOCK TABLE MY_TABLE IN EXCLUSIVE MODE NOWAIT;
        COMMIT;
     LOCK TABLE MY_TABLE IN SHARE MODE NOWAIT;
EXCEPTION
     WHEN OTHERS THEN
           dbms_output.PUT_LINE(SQLERRM);
          ROLLBACK;
END;
/The purpose is to lock the table so that if another user accidentally tries to execute the script s/he won't be able to modify the data in the table.
However, if the procedure is already running when another user tries to execute it, the 2nd user simply sees the procedure to terminate very quickly (it normally takes around 15-20 minutes based on the data). No message that the table is locked or that the procedure is in progress from another user.
How can I notify the 2nd user that the procedure is already in progress from another user or that the table is locked? What should I put in the EXCEPTION part maybe to do that?
Thank you in advance.
Regards,
John.

PRAGMA EXCEPTION_INIT(already_lock, -54);is 54 value meant for in-buit exception table
le locked, if so, even without having a custom
exception, oracle by itself would have thrown it in
the second session, right???, please do correct me if
iam wrong,
-54, and yes it is.
>
what will be the impact if i have a WAIT instead of
f NOWAIT, will my second session just be on hold
waiting for lock to be released???Second session will wait... but WAIT doesn't exist, just write lock table t3 IN EXCLUSIVE MODE ;I advise you to read this for LOCK command : http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_914a.htm#2064408

Issue: Lock table is out of available object entries

Hi all,
We have a method to add records into BDB, and after there are more than 10000 records, if we continue add records into BDB, such as add 400 records into BDB, then do other update/add operation to BDB, it will be failed.
