How to find the locked row.

We see a lock of line blocking other operations, but cannot identify the application JAVA thread that performs the lock. Is there a way to know which line of the table is locked. If this is possible, will help developers identify the problematic program thread.

Thank you

A good example of diagnosis here: -.

http://Advait.WordPress.com/2008/06/21/identifying-locks-on-objects-using-vlocks/

Select row_wait_obj #, row_wait_file #, row_wait_block #, row_wait_row #.
session $ v where sid = 91;

Select dbms_rowid.rowid_create (1, ROW_WAIT_OBJ #, ROW_WAIT_FILE #, ROW_WAIT_BLOCK #, ROW_WAIT_ROW #)
session $ v where sid = 91;

    Hi all

    Ideally, you should check for locks on the table in question where records are trying to access.

    AFAIK, you must check the v$ locked_object and find sessions.

    Hope this helps!

    Hi all

    I am new to Oracle Apps, we I run my simultaneous program
    its taking too long to complete. How to find that there is a lock to produce in the table while that simultaneous execution of the program, another way to find why the simultaneous program takes too long to run and how can you speed up the process.

    Yesterday we made a few changes to speed up the process with our DBA to accelerate the simultaneous program

    The first simultaneous program takes 2 h 30 and after these changes taking 1 h 45. Please suggest it's okay

    Connected with the responsibility of the system administrator.

    Manager - set - Manager of the standard.

    Set the value of PROCESS like 15 (instead of 10).

    Set the value of SECONDS of SLEEP as 10 (Changed from 30).

    Hello

    I suggest you draw the simultaneous program and analyze the trace file. To do this, mark the simultaneous program as Trace enable (RESP system administrator, Menu simultaneous > program > define) and then run the program and download the trace file after dealing with tkprof. Check which are the staements who take most of the time and try to optimize them.

    It will be useful.

  • How to find the employee is rehired

    Hello

    How to find the employee is rehired?

    through Front End and back End

    Thank you.

    You're looking to identify if an employee was re-employed, or looking to find all employees who were rehired?

    To determine if an employee was re-employed:
    (1) place you * HRMS Manager > people > enter & maintain
    (2) look at the employee's most recent Start Date field
    (3) compare this to their first Date field engaged in the Services tab

    If the two are different, it means that the employee was re-employed.

    Technically, each period of employment is linked to their period of Service. They will be on the per_periods_of_service table. So, there are 3 rows in per_periods_of_service if an employee was re-employed twice (that is to say, initially engaged and then reembauche twice).

    I hope this helps.

  • How to find the status of lines (modified or not)

    Hello

    Is it possible to find if a line status is modified (but not committed) and user who made the change?
    Avoid locking if we want to check if there is a line in our select statement can cause the deadlock.

    your response is so much appreciated

    In this case, you can skip all the locked rows. This is a clause without papers prior to Oracle 11 g. The following code illustrates the approach:

    // we create a test table with 10 rows
    SQL> create table footab as
      2  select rownum as FOO_ID, object_name as VALUE from all_objects where owner = 'SYS' and rownum  < 11;
    
    Table created.
    
    // we create a procedure that will pretend to be another session trying to update the table, while
    // we are busy updating some rows (it is an autonomous transaction)
    SQL> create or replace procedure UpdateFoo is
      2          pragma autonomous_transaction;
      3
      4          cursor c is
      5          select
      6                  f.*
      7          from    footab f
      8          for update

     10
     11          type TBuffer is table of c%rowtype;
     12          buffer TBuffer;
     13  begin
     14          -- an ugly loop hack used to demonstrate what it can lock
     15          -- and updating those rows
     16          open c;
     17          loop

    What happens if the PL/SQL table has NULL values. Question is how you want to handle NULL values. You want to ignore nulls as GROUP BY do? If you want to consider NULL values, you can say if you want to order the NULLS FIRST or NULLS LAST. I guess that logical GROUP BY:

  • Mr President, how to find the last DML operations

    Hello

    Please tell me how to find the last DML operations at least a minimum of 30 queries.

    Thanks in advance,

    Select sql_id, sql_text, last_load_Time from V$ SQLAREA

    or

    Select * from v$ sqltext

    Must be one of them. But don't know what exactly you are looking at.

    I usually use v$ sqlarea to see recent queries.

    Maybe you can limit the rows using rownum, order of last_load_time.

    I understand, if the same query is used again then only recent transaction is stored.
