Can DataPump Export Compress the Dump file?

hi everyone,
This is 10g.
I use the expdp utility to export 1 schema at month-end. The size of the .dmp file is 9 GB.
Can expdp perfrom compression to reduce the size of the dump file ?
Thanks, John

Thanks Srini and Dean.
I dont have 11g so I could only benefit by 10g's ability to compress metadata.
My monthly export is for 1 user schema. I assume the schema contains both data and metadata which means if I requested compression, I would get a smaller dump file. Is that a good assumption? Would I still get only 1 dump file or do you get more than one file when compression is used?
The 10g documentation I have read about expdp does not mention how to request compression.
Thanks, John

    You should buy Compressor it never fails. It is a must have. I have given up using this buggy Share function and use Compressor all the time.

  • Can we find the number of rows in table from the dump file

    Hi All,
    Can we find the number of rows in table from the dump file with out importing the table in to the database?
    Please let me know ,if any option is there.
    Thanks,
    Kumar.

    <s>Try to import with option SHOW=Y, that should skip the number of rows which are into a table from a dump file.</s><br>

  • How can I export to a .sfw file? it does not give me the option in FILE EXPORT.

    how can I export to a .sfw file? it does not give me the option in FILE > EXPORT. I have Flash installed and everthing.

    The feature to export SWF files directly from After Effects has been removed. It never worked at all well.
    To create SWF files, use Flash Professional.
    If you want to play a movie that you've created in After Effects in a SWF container, then export your composition using Adobe Media Encoder in H.264 format and then link or embed that movie into a SWF file in Flash Professional.

  • How can i export a 24bit avi file from photoshop for mac?

    how can i export a 24bit avi file from photoshop for mac? i have a client that specificly needs the files to be avi and in 24bit what are the settings that i need to use to export the video using photoshop on a mac?

    Hello,
      To make a 24-bit AVI file in Photoshop, go to File>Export>Render Video. Then, under File Options, choose AVI from the Quicktime Export drop-down menu. Click the Settings button. Click the Settings button in the AVI Settings window. Change Compression to None, and then choose "Millions of Colors" from the Depth drop-down under Compression.
      The Millions of Colors option is for 24-bit video (8-bit R+G+B channels, 8x3=24). Millions of Colors+ is for 32-bit video (24-bit video plus an 8-bit alpha channel).

  • Estimate the Import Time by viewing the DUMP File Size

    Its very generic question and I know it can varry from DB to DB.
    But is there any standard way that we can Estimate the Oracle dump import time by viewing the Export Dump file size ?

    Well, it's going to be vaguely linear, in that it probably takes about twice as long to load a 2 GB dump file as to load a 1 GB dump file, all else being equal. Of course, all things rarely are equal.
    For example,
    - Since only index DDL is stored in the dump file, dumps from systems with a lot of indexes will take longer to load than dumps from systems with few indexes, all else being equal.
    - Doing a direct path load will generally be more efficient than doing a conventional path load

  • What is the dump file size limit?

    Hello all,
    Can somebody tell me what is the maximum size of the dump file created by export utility in Oracle? Is there any maximum size applicable to dump file?
    Thanks in advance
    Himanshu

    Hi,
    Later Oracle 8.1.6, is no more Oracle limitation on dump file, with restriction 2Gb for full 32-bits OS (32-bit with 32-bit files). The maximum value that can be stored in a file is dependent on your operating system.

    how's compress the edge file?

    You can't.
    The best you can do is pre-plan your project.
    - use compressed images;
    - use less dependency on local font or script references and use CDN or available web services instead;
    Just a few thoughts

  • Cannot compress the WebFolders file

    Hi,
    I encountered an error when I try to backup an AppSet.
    It was Cannot compress the WebFolders file.
    Anybody can help to solve this issue?
    Thank you!
    Sunny

    To compress the webfolder the BPC is using zip of windows.
    Windows zip can not be used if the appset webfolder is bigger than 2GB.
    If the size of yor appsetr webfolder is smaller than 2GB then the problem it is other.
    In this case you have a file without owner.
    That's means you have to use explore to select the appfolder to click right and properties of that folder.
    You have to go to security and click on button advance
    Go to tab owner and there you have to be sure that you have at least one user.
    Select check box "Replace owner..." and after that ok, ok, ok
    After that you have to go one more time into security of that webfolder and to propagate the security to all childrens.
    If you did all these things then you should be able to backup the appset. (at least to zip the webfolders)
    Regards
