Security move the table to another tablespace

I would like to pass on my table to a different tablespace by using the statement:
ALTER TABLE table_name move tablespace new_tablespace;

I am interested in what happens if someone wants to select or modify some data during the process of alteration (on the table table_name). I tested on the database of test (without a users) and everything was OK, but I wonder what happens if someone edit or select data. Could you recommend me how to protect this table? Change in playback mode or change the database in the mode of restriction? Thanks for the tips.

Hello

The table is locked automatically during the MOVE ALTER TABLE. If other sessions can still perform selects, but no changes can be made during the DDL.
Don't forget to re-create the indexes on the table later.

  • Move the table in same tablespace is not reorganize the data

    Hello.

    I am facing a problem that I have not used to have.  First of all, a description of our envorinnement:

    We have a few large tables partitioned and performance optimization, our ETLs use bluk, add notes, parallelism and so on.  This create several holes of unused space in tablespaces/data files as well a kind of leak of space on our drives.

    A complete correction would re-create the tablespaces move everything is of opposes another.  It would be impratical, because there are about 15 who are top of 100 GB; the time and effort to recreate everything is not affordable for the Business.

    Instead, we have a single proc that comes to calculate the actual amount of used space (converted to blocks) and makes a move of all objects above this block_id.  Just after this operation, there is a dynamic shrink based on the new HWM (given that the objects have been moved) on the data file freeing disk space.  As we have a datafile by tablespace and a tablespace by schema, we would like to keep this body, if we make a single movement for objects, like 'ALTER TABLE' | owner: '. ' || nom_segment | "MOVE; "(the complete query works with all types of data such as partitions of table objects, the index partitions and the subpartions).  This will move the object in the same space for the first freespace on the tables and free up space at the end of the file to shrink.  In theory.

    This unique proc used to work properly.  In a 650 GB GB 530 tablespace in use moving about 20 that Go (the amount of data beyond the HWM 530 GB) is simpler than to create a new file/TBS and the displacement of 20 GB is faster than Go 530.

    But suddenly things changed when some TBS refused to be narrowed.  What I found out: the command move doesn't fail, it works very well and Oracle really moves the object.  But for reasons that I don't know, he's not moving it at the beginning of the file, it keeps the object at the end.  So the da calculates the new HWM, but because some objects that were in the tail of the queue, the shrink is done with a very high HWM, if no real space is reclaimed.

    So, the main question: How does the ALTER TABLE FOO MOVE really works?  I thought that it would be always to move the object to the beginning of the file thus reorganize, but I analyzed the last objects that gave me this problem (block_id before and after the move, compared to block_ids empty and everything) and actually, I see that they were moved at the end of the file, although there is enough space to accommodate initially.

    Okay, I think I found the problem.  Before that I just pulled the script as posted, but then I had the good idea to improve its performance with parallelism, so I added:

    ALTER SESSION FORCE PARALLEL QUERY 16 PARALLELS;

    ALTER SESSION FORCE PARALLEL DDL PARALLEL 16;

    ALTER SESSION FORCE PARALLEL DML PARALLEL 16;

    Returning to prallel not running, that I could reuse the freespace on the beginning of the file, and then narrow it down.

    Obviously, each writing data in parallel mode reuse freespace, I just forgot that a TABLE ALTER MOVE is also a data write operation.  I fell a bit ridiculous, caught in the same trap that I was trying hard.

    Thank you all for the comments and advice.

  • How data form move one table to another table

    Hai All

    I have two tables and a table, I need to move data to another table.

    First table t1 has 3fields
    code, date, time

    Second table t2 has 8fields

    code, intimate, outtime, att_date, perin, intrinsically, perout, introut

    The table t1, I need to move the data to the t2.

    for example
    Bartime bardate barcode

    02/01/10 0011, 0815

    02/01/10 0022, 0820

     select barcode, bardate,
            max(decode(rn,1,bartime,null)) timein,

  • How can I move the OS to another drive.

    Thanks in advance for any help/suggestions, C ;-)

    Hello cindy906, you should be able to add a smaller hard drive to your system and use the restore disks HP recovery that you should already have, while leaving the current hard drive installed.

    There is a question that you would need to know. If you leave the current hard drive cables connected and use the Recovey HP restore to reimage the new hard drive, when you start the installation of the Windows operating system, the installation program (System partition) can be changed on the current hard drive. If you install Windows7 SP1, the Boot Manager will be changed and make the current version no longer starts.

    Windows 7 creates a configuration (System) partition when it installs hidden. When there is already a system on a system partition, Windows 7 will be find and replace it with the new OS when you update to Windows 7 SP1.

    Once the new disk has been reimagee with the game to restore HP Recovery disks, and the operating system has been installed, you can then reconnect the cables on the current hard drive and use it as a backup drive or delete it if you prefer.

    You would not be able to move the current hard disk to another system, for legal reasons and problems of compatibility with the already installed drivers for the HP computer, unless you formatted the hard drive and deleted the C: and D: partitions and the hidden partition of 100 MB.

    If all three partitions are formatted, the reader could be wiped clean and could be used on another system.

  • Move the system on another drive partition.

    I have 4 hard drives on my Windows 7 system.  Readers 1 & 2 are defined in a RAID 1 configuration (labeled Disk 0 disk c).  Disc 3 (labeled Disk 1 drive F :) is were the 100 MB Partition reserved system resides.)  This drive has the SMART errors.  How can I move the system reserved on a healthy disk partition?

    Hello

    Thanks for posting your question in the Microsoft community

    After the description of the question, I understand that you want to move the different system for the drive partition. I'll be happy to help you on this question.

    1. What is the accurate and complete error message you get?
    2. What is the letter of the drive for this partition not formatted?

    Let us try the following steps.

    If the 100MB partition not formatted the disk '1' before the C: drive, follow the below mentioned steps.
    a. create a repair disk.
    Create a system repair disc:
    http://Windows.Microsoft.com/en-in/Windows7/create-a-system-repair-disc

    b. create a new simple partition.

    c. assign a drive letter (ex: 'Z').

    d. copy a folder and two files to the system partition reserved current (drive '0')

    Boot

    Bootmgr

    BOOTSECT. BAK

    e. remove the drive letter of the partition 'System Reserved' old ('0' drive)

    f. mark the new "System Reserved" boot partition as "Active".

    g. restart the computer and check if his boot to the desktop.

    h. If the computer does not start, then using the disk repair repair startup.
    Startup Repair: frequently asked questions:

    You seem to always have the same problem, but give it different titles. It would be much easier that you would hold a thread open until its resolved. The last time you had this problem that I posted the following code, it didn't help you? (Replace x and y in each if or ELSIF with the calendar you want to watch)

    CURSOR cr IS
      SELECT CODE,
             DATE,
             TIME
        FROM FROM TEMP_ATTENDANCE
       ORDER BY CODE, DATE, TIME;
    BEGIN
      FOR rec IN cr LOOP
        IF rec.TIME BETWEEN x AND Y THEN
          -- Update record for last day
          ..
        ELSIF rec.TIME BETWEEN x AND Y THEN
          -- Update record
         ..
        ELSIF rec.TIME BETWEEN x AND Y THEN
          -- Update record
         ..
        ELSIF rec.TIME BETWEEN x AND Y THEN
          -- Update record
         ..
        ELSIF rec.TIME BETWEEN x AND Y THEN
          -- Update record
         ..
        ELSIF rec.TIME BETWEEN x AND Y THEN
          -- Update record
         ..
        END IF;
      END LOOP;
    END;
