How to decrease the level of fragmentation of a table.

Hi all

There is a table in my database of production.
His version is Oracle 10 G (10.2.0.1.0)

(i) its size is 26 GB with level of fragmentation.
(II) it has more then 48 crores of lines.
(III) its size is 20 GB without fragmentation level. (Up to 6 GB of unused space is wasted).

Here are my doubts about the above points.

(i) how to reduce the level of fragmentation of the table.

(II) if there is a way to reduce the level of fragmentation, how long it will take to perform the particular activity in order to reduce the level of fragmentation.

Move the table into a new table space and rebuild the indexes.

Asif Kabir

  • How to decrease the size of the PDF file without reducing the quality and links?

    How to decrease the size of the PDF file without reducing the quality and links?

    Michael and Phil,

    Your ability to reduce the file without diminishing its quality depends on the quality required for their intended use. If these are intended for viewing on screen, then high resolution pictures can be re sampled or changing the resolution without real change is the quality, as long as the user can say. Number of files use subsets of fonts or the incorporations of fonts. Sometimes you can remove subsets of fonts or embedding the fonts if the font will be on the user's system. Subsets of fonts can save space, but if the pdf is a result of several different sources, desincorporation policies and incorporating a copy of the policy can save space.

    Honestly, the size of 2 MB file is not the problem it once was. However, maybe the pdf not by e-mail at all. There are players on a server as well as a link sent to each user.

  • How to change the PCTFREE parameter for an existing table

    How to change the PCTFREE parameter for an existing table?

    Guys can you help me please

    Hello

    Of course it is possible.
    In this case you would export the table from the database (using old style exp)
    Start the import with the index_file option to generate the table/index instructions
    Modify the file created and updated the PCTFREE and remove any that need to be performed (default, if I remember correctly, he comments on the statements of the Index)
    Run the file for the table and the index created
    After that start the import with the option "ignore = yes".

    Make sure that you export only this particular table using "tables =
    Also in importing the "ignore = yes" will also be important data that still exists.

    In my view, however, this is not what you want to do. It's more complex, sensitive failure and the table should be deleted, so users are affected unnecessarily long.

    Success!

  • How to increase the level of Effort BY?

    Hello

    I am trying to restore a primary application of a number of separate projects of component LVFPGA LVFPGA.  Each of these smaller basic functions is running in their own SCTL in new the LVFPGA master file.  Small functions all meet them timing, but not the master app.

    I use about half of the chip so it seems to me that it should not be difficult to place and route.

    When my compilation fails because of time constraints, he says the following:

    WARNING: By: 62 - your design did not meet calendar.  Here are some suggestions to help you to keep to the timetable in your design.

    ...

    Increase the setting of the level of Effort BY to 'high '.

    Use the 'xplorer' Xilinx script to try special combinations of options known to produce very good results.

    See http://www.xilinx.com/ise/implementation/Xplorer.htm for more details.

    So my questions are:

    (1) how can I increase the level of Effort BY?  Has NEITHER provided a hook for setting this value and if so what is its current level / by default?

    (2) we access level user to the script 'xplorer '?  If so, where is this located and can OR recommend some parameters that are compatible with the SMU-5641R.

    Thank you

    The files in the folder of Xilinx are never overwritten or replaced, these default values are simply not used if you provide your own .opt files to the compilation sequence. For these two products, we provide custom files, I've already mentioned. These custom options are communicated to the server during each request compilation as it must have everything necessary to provide correct results regardless of compilation locally or remotely (or even on a remote compiling the server who has not installed the drivers from target).

    Insofar as you need exactly what settings level effort, which will be dependent on the design. I suggest you look at Xilinx documentation on their suggestions on how to set these options based on what kind of compile questions that you hit. In general, I would try them likely increases in the following (probably with compilation time) order:

    "" plan of access-Calendar - ol std' and ' normal - ol std ".

    'map - calendar - ol high' and ' "normal - ol std".

    "map - calendar - ol high' and ' by - ol high."

    [Or if you will just operate all night and don't care about compile time, you could jump to top/high... and work backwards if you want to use the minimum effort it takes actually.]

    If these don't work for you (or if you want an alternative solution), then you need to review your design and your code to see if you can improve the synchronization in the areas which are at the origin of chess.

    Side-note:

    Modifying the files in the directory of Xilinx does not apply to this situation. I do not know the behavior to change these files, but it would be easy to deduce by experimentation (i.e. edit the file locally, perform a remote generation, see if the changed options were used... If not, then restore the local file, the remote file instead, rebuild, etc.). But even once, it does not apply to these objectives and behavior will be verified based on file by a specific version of LabVIEW file, since it is an implementation detail that may change.

  • How to track the level of Keyframe Audio digitally

    Hello

    I want to change the volume of a track of time time by submitting digital values for the volume of a track at a time B and B and let first edit of a track volume accordingly during playback. Basically, how I update the value of the key frame digitally? How this is done?

    http://files.2he.com/uploads2/2013_08_17_18_15_18.jpg

    When I put the time in the timeline slider and adjust the volume of the track in the audio mixer Panel and then click on the diamond add keyframe at the head of the trail, then it creates a new keyframe, but not with the value of the volume in Control Panel mixer audio-track. Unless it was the very first keyframe, I created.

    I don't want to edit the keyframes of volume by dragging, which does not have enough accurate for not even approaching the target volume control.

    I don't want to save live track-cursor change in the Audio Mixer Panel.

    At http://help.adobe.com/en_US/premierepro/cs/using/WS1c9bc5c2e465a58a91cf0b1038518aef7-7f35a .html I saw "Adjust" tracking volume with keyframes, but has not been able to find a «...» " Follow > Volume on the menu drop-down at the top of the element in the audio track ', seems that fits the volume of clip again and don't not to track the volume.

    Well, you can't be happy with my answer, but it's the only way I know to enter the level by typing a number.

    If you set mixer track for this particular to 'Write' track and enter the desired number, let's say-6 dB, then you press the playback on the timeline, when you stop playback, key frames will have been defined at this level. You can the left and right arrows to do the job also.

    You find that you want to move keyframes after doing this and be careful to not crush the other keyframes, but it does not work.

    Dear Suzy,

    I was looking for a patch of database being upgraded. After the database owner (enviroment) to supply file, I used the following command from $ORACLE_RDBMS_HOME/OPatch directory, command like $ OPatch lsinventory, he listed all the patches and updated patch also.

    'OPatch lsinventory' must list all patches applied to $RDBMS_ORACLE_HOME. For the level of database of the Group of hotfixes, you can use one of the instructions above to get the version. In addition, you can check to the BONE by running executable files (i.e. sqlplus, impdb... etc).

    And on request, I used-> -use $AD_TOP/sql/adutconf.sql , it is perfectly correct.

    Ok.
