Need help with export, truncate and import partitions for schema

I need to export a couple partions for our Oracle 10g Data Warehouse, truncate the partions and re-import the data using the exported file. How can I do this?
In summary here is what I need to do:
1) Export partition P_SUB_1 of table1
2) Export partition P_SUB2 of table2
3) Truncate P_SUB1 partition of table1
4) Truncate P_SUB2 partition of table2
5) Rebuild indexes on table1 and table2
6) Re-import data into each partition from export files.

If you have enough free space it might be easier to keep these partition in the database and do an exchange.
That means:
create table tmp_sub1 as select * from table1 where 1=0;
create table tmp_sub2 as select * from table2 where 1=0;
alter table table1 exchange partition sub1 with table tmp_sub1;
alter table table2 exchange partition sub2 with table tmp_sub2;After that your have the data of your original partitions in the tmp tables and the particular partitions in the partitioned table are empty and ready for the loading process.
If the loading process fail and you need to restore the partitions just reverse the exchange statements and you are done.

  • Need help with Airport Express and so on.

    Ok so my main problem before getting into what I need help with here is that our MacBooks and now my iPhone 6 plus isn't staying online. Keep getting booted off and then I either have to select the network again or it will eventually go back on. If anyone has a solution or so please feel free to answer that as well. I'm running on Roadrunner with a Netgear 600 wireless router and a motorola modem. Both of which I'll leave the link to below for a better look.
    My Main Question: So I'm looking at a new wireless router mainly and possibly a new modem. I know Apple products are trustworthy but how good is the Airport Express and other Airport products. Also what is the Maximum speed and Maximum data speed for the cheapest express station and if anyone knows the speeds of the other devices it would be greatly appreciated.

    DSL Router to Netgear 5-port Switch and I used the switch to connect to Airport Extreme, TV, Blue-Ray DVD player and DirecTV Receiver.
    The AirPort Extreme base station (AEBS) is a router so it will do what you need.
    You need to reconfigure your setup. Connect the WAN port of the AEBS to the DSL router. Then connect the Netgear switch to one of the LAN ports on the AEBS. The AEBS will properly share the connection.

  • Need help with Page Layout and Background Scaling

    hello, everyone.
    I am in the process of designing a new website for myself,
    and while I was researching nicely designed pages to use as
    inspiration, I stumbled upon this site:
    http://www.jeffsarmiento.com/
    obviously, the design is very impressive, but it also
    incorporates a lot of web mechanics that I have been trying to
    figure out, so I will use this page as an example.
    one thing I need help with is backgrounds. as you can see in
    the posted website, the creator used a seamlessly tiled paper
    texture to display the bulk of his content on. also make not of the
    pattern that is located to the left of the paper texture. how do I
    create seamless backgrounds like this that will scale to fit any
    amount of content or any resolution? I can't imagine that the guy
    that made that site created a new size background every time he
    made an update, so there has to be an easier way.
    the second thing that I am having trouble with is general
    site layout. I have read that most sites used series of invisible
    tables to organize there content, but when I open the source of
    this page in dreamweaver, he was using something different. div
    tags? should I be using these? who do I use them? are there any
    general layout tips that someone could pass on to me? perhaps a
    link to a good tutorial?
    please help me. i am very confused.
    thanks so much.

    IMO not a good site to emulate. To wit:
    Top background image:
    http://www.jeffsarmiento.com/images/bg-top.jpg;
    745px

    Main background image:

    745px x 950px 130K
    Total page size: 454K (Check here:
    www.websiteoptimization.com)
    Website usability experts routinely recommend a maximum page
    size of ~80K
    Check out the We We Scale @ www.FutureNowInc.com/wewe/ where
    they suggest,
    "You speak about yourself approximately 0,003 times as often
    as you speak
    about your customers. Might that have an impact on your
    effectiveness?"
    That is 100% consistent with the #1 Web Design mistake:
    "Believing people
    care about you and your web site." or to phrase more
    expansively, "Our site
    tries to tell you how wonderful we are as a company, but not
    how we're going
    to solve your problems."
    www.sitepoint.com has some excellent books on making a
    website actually
    attractive and usable at the same time.

  • Need help with show/hide and layers moving

    I'm more of a designer, so I don't know code or CSS well at
    all. I'm doing an online portfolio for a class and need help with
    layers not staying in place in different browsers. The portfolio is
    created with a table, but I wanted to use the show/hide function
    for thumbnails of work. Are layers the only way you can use this
    function? I read layers don't work well with tables, so how else
    can I make it so when you mouse over a thumbnail, the larger image
    appears in another cell?

    > I don't know code or CSS well at all.
    That's unfortunate.
    > layers not staying in place in different browsers.
    Layers don't move. But the rest of your page does.
    Before you get too wrapped up in layers, though, please read
    this -
    http://www.great-web-sights.com/g_layerlaws.asp
    They are not good when be used as a primary layout method.
    > I read layers don't work well with tables
    They work fine with tables - but you have to understand both
    tables and
    layers to use them.
    Why not show us your page, so we can see what you are
    struggling with?

  • Need help with a customized interactive web application for  apparel

    Help!!!!
    Hi I am a web designer at beginners stage with web

    interactive web application so that the end user can change color
    and patterns of apparel on vector images such as teamsports
    uniforms and tshirts. Once the design is customized to their liking
    they can save it with all of the spec information in a file to
    there desktop or to a database to send to the manufacturer.
    Also looking for a possible way to use a CMS so I can upload
    templates of the garment easily for the end user to customize
    online. Can this be done and if so how? This is an example the kind

    "Reap what you sew"

    some parts of that are doable using non-advanced skills, but
    will be difficult and unwieldly if there are more than a few
    colors/patterns.
    saving the image to the server is a bit more advanced and
    you're going to need some server-side scripting like php, perl, asp
    etc. in addition to some flash programming ability.

  • I need help with re installing my apple account for itunes.

    Had problems with my itune account, so I uninstalled and now need help with re-installing the program with the songs I have already purchased.

    Your iTunes account is something at the iTunes Store online.  It is not possible to uninstall it.  Do you mean the iTunes application?  Even if you delete the application and restore it, it should not have deleted your iTunes library (essentially the contents of the iTunes folder in Music) on your computer unless you did a separate steep and specifically deleted that too.  You need to tell us what it was you deleted.

  • FCP Novice needs help with video quality and FCP 5!!

    Hi,
    I have a real problme that I cannot seem to fix. I think its because I am doing something really wrong!
    I have a Sony HC42E MiniDV Camcorder which by default records video in full widescreen. I recorded several tapes this way and have now begun trying to edit them in FCP 5.04 (Tiger 10.4.6). Whenever I log and capture my clips they appear to be fuzzzy and unclear on the Mac monitor whilst being totally crisp and sharp on the camcorder viewfinder. I tried capturing using the DV PAL 48Khz Anamorphic Preset which keeps everything the right size (the final output needs to be true widescreen and not with black bars added) but the resulting video on screen is blurry and bitty. I then tried capturing using the DV PAL 720 x 576 normal preset and the video is a little clearer on the screen (for both presets I have chosen lower field dominance) but when I play back it plays back in widescreen on the mac canvas window but at 4:3 on the camera's viewfinder.
    I then assumed that maybe this is just becuase the mac screen (CRT by the way) doesn't use fields. So I exported the sequence as a QT movie using DV PAL 16:9 and used quicktime (OS9 Classic - my compressor has never worked because of the dreaded "unable to connect to baackground process" problem which I've never managed to correct) to convert it to MPEG2. When I import this as an asset into DVD Studio pro 4 and set the track size to 16:9 it comes through at the right aspect ratio. However it looks blurry on screen. Thinking that this will be fine on a TV I burned the disc - inserted it into my DVD player (a good one!) and watched it on my new 32" widescreen TV (a good one!) and the picture qualitty is poor. Its so much blurrier and bittier than the original footage looks when played through the camcorder's viewfinder!
    The final footaage looks like an old VHS recording that's a year or two old!
    Does anyone know how I can capture my footage in FCP with the maximum quality, edit it without quality loss and the export it for DVD again without such significant quality loss whilst all the time keeping it at proper 16:9 widescreen?
    Is there some presets I should be working to?
    I'm tearing my hair out! Help!

    Hi Guys,
    thanx for your replies.
    here's the latest:
    Brian, I followed your instructions and the DVD burned successfully. However the video quality of the dvd when viewed on my TV ('ve tried on all 3 of my tvs now) is still a lot poorer than the quicktime movie that was imported into DVDSP4. When I play the original QT Movie on my Mac CRT monitor it looks a little blurry and grainy because I guess its non interlaced however when viewed on an external Video monitor it looks great - very sharp.
    When I view the burned DVD on my television the picture quality looks like the non interlaced version of the original QT Movie that appeared on my Mac CRT and not the sharp interlaced (lower field) version that appeared on my external video monitor.
    Its almost like taking a sharp jpeg into Photoshop and applying a gaussian blur of about 0.3 followed by jepg compression compressing it down to 5% quality!
    I'm totally mystified. Can the conversion to Mpeg2 be removing all interlacing so that you get the less sharp computer monitor look? I just want the video on my final DVDs to be as good as the original source footage! I appreciate that along the way there might be loss of some quality but surely not that much?
    Does this make sense to you guys or am I still doing something very wrong?
    Robert: I have tried setting all manner of drives including a fresh external firewire HD with nothing on it (clean out of the box) but it doesn't seem to help.
    Brian: I tried the no network suggestion a few months back but I'm not sure if I got it right. At the moment I have broadband through an external speedtouch usb modem and am also connected (occasionally although not for the last 3 months) via a crossover cable to my PCs ethernet card. When I last tried the No Network solution I had immense trouble getting my internet to work again! Can you please help me by directing me to the best ay to do this while protecting my internet settings?
    any more help guys would be greatfully appreciated.

  • I need help with export settings

    Hi everyone,
    I need help outputting an HD file for presenting a video to a client. I have tried exporting to HD .mov (H.264 codec) and PE keeps crashing (error compiling movie). From what I’ve read here, it’s due to the gargantuan file QT creates and HD space (even though I think I have enough HD available).
    So, I need a recommendation from you on what kind of file to output which will allow me to present the movie to the client in HD. This file is solely for the presentation, I have already published for web (FLV) and YouTube (direct share from PE) and they both worked fine.
    Here are my project specs:
    Timeline:           4:26
    Format:               1920 X 1080 HD
    Timebase:          29.97 frames per second
    OS:                        Windows XP SP3
    Processor:          Intel Core 2 Duo @ 2.66GHz
    RAM:                    4GB
    Project Drive:   250GB disk with 152GB free space internal dedicated project drive (separate from OS)
    Thanks in advance for your help,
    Jose

    Hi Steve, Neale,
    I wanted to follow-up on this post. I came into the office today to run a few tests so I can make sure that I have the correct settings on my camera and PE project for the next time around. Here are few observations I was wondering if you can comment on:
    My Sony camera cannot shoot HDV. The only format it supports is AVCHD, so I'm stuck converting.
    I tried to convert the footage I have to HDV with the software I have (AVS Video Converter and Koyote Soft HD Converter) and neither of the two have an "HDV" conversion setting. I see AVI, MPEG, MOV and many different settings in each (AVI: Hd Video 1080p: H.264AVC, 29.97fps, 4200kbps, Audio MP3, 256 kbps or MPEG: HD Video 1080p - MPEG2, 15000 kbps, 1920X1080, 29.97fps, etc). What should I be looking for?
    I searched for "best file format" in the forum and found various postings from both of you referring to converting to DV-AVI within PE; especially if you have AVCHD footage (which I have). So, I followed directions and converted a file for testing. Then, I created a new project using HDV 1080i 30 settings and imported the converted file. I still get a red line on the timeline. Any thoughts on what I'm doing wrong?
    I also converted the MOV files (shot in HDV 60i with the pro camera) to DV-AVI. I also get a red line on the timeline...
    The DV-AVI converted footage (both cases) doesn't appear to be HD. It looks jagged on the preview window. Is it HD?
    The DV-AVI converted footage is almost double the file size as the MTS (AVCHAD) file (138mb vs. 60mb). Isn't that going to make PE run slower?

  • Need help with exporting iphoto to dvd

    Hi,
    I am trying to export a bunch of albums from iphoto to a brand new dvd-r disc.  I am trying to move the photos to free up more space on the computer. I get the message "there is not enough disk space to complete this operation"  when I try to export just one album (total 826mb).  I still have 870mb free on my HD.   Thanks for your help.

    I still have 870mb free on my HD. 
    You have a major crisis right now and you need to solve it immeadiately.
    OS X needs about 10 gigs of hard drive space for normal OS operations - things like virtual memory, temporary files and so on.
    Without this space your Mac will slow down as the OS hunts for space on the disk, files will be fragmented, also slowing things down, apps will crash and the risk of data corruption - that is damage to your files, photos, music - increases exponentially.
    Your first priority is to make more space on that HD.
    Nothing else can be done until you do. Purchase an external HD and move your Photos and Music to it. Both iPhoto and iTunes can run perfectly well with the Library on an external disk.
    Burning material to optical disk will not work Creating a disk needs a large amount fo disk space - at least twice the amount you think you need.
    But really, you must make space on that HD. You are in grave danger of losing important data.
    Regards

  • Need help with WinXP 64 and raid please...

    First off let me just say that for the past week or two I've been lurking on this forum while building my first 64 bit pc and I just want to say that all of your advice, suggestions, tips, and workarounds have proven to be invaluable. A sincere, heartfelt thanks to everyone here.   Like many of yours, my build has also been problematic. In fact, I guess I'd have to call it a pain in the ass. I can't imagine having done it without your help by using trial & error, so once again; thanks! Now, on to my ? My plan was to have one PATA 40gb HD to house 2 OS's on 2 partitions; a dual boot with XP and XP64, AND one RAID 0 made up of 2 160gb SATA HD's for everything else (actually the plan was to put the OS's on a Raptor but $$$). Now here's the prob: XP's up and running fine but when I try installing XP64 and it asks for the RAID drivers, it won't take them. It says they're not for a 64 bit OS. ? Am I the only one that thinks that odd? Isn't that the ultimate point of all this? So am I missing something? I d/l'd the 64 bit drivers from NVidia, is there a way to extract RAID drivers from them to a floppy? Also, I'd like both OS's to utilize the same RAID array for programs, storage etc. Is that a problem (my first time installing RAID   )? And if it WILL work, is it going to insist on wiping the drives and starting fresh? I hope not since since I've already got a ton of stuff on there. Anyway, thanks in advance for any and all help you might offer. Keep up the good work. -Glyph

    Thanks for your quick responses. So are you saying that if my OS isn't on the RAID array then I don't need the RAID drivers during setup? That's interesting. It's not how I understood it to be (not to say your wrong though). I'm pretty sure I needed them in WinXP, though it's on a different disc as well. Now that I think about it, maybe I could've waited and installed them through device manager with the same end result? I guess I'll try it and find out. And are there any ideas regarding the 2nd part of my question re data loss? I'd really hate to start from scratch at this point.

  • I need help understanding export options and optimizing for web

    I have been using FCP X for a short while now and have a pretty good grasp on the editing capabilities. What I'm having a horrible time figuring out is the export/share options. The videos I create are typically approximately 1 minute in length and get posted to a web site (we have our own CMS and video player so I'm not using YouTube or Vimeo or anything like that). In order to post them I need them to be MP4s and then I have to create .webm and .ogv files. The source material I work with is generally great, high quality stuff, so I end up with very large output files from the initial FCP share master file options.
    When I use MPEG Streamclip to make my MP4s I end up with files that are still quite large and I can't seem to ever get the file size manageable without losing tons of quality. I do not have Compressor, though if that will solve my problem I will put in for the expense of it. What I'm trying to understand is what sorts of settings I should be trying out to get my file sizes to be manageable without completely compromising my quality. And I know this can be done, because the company I work for pays for a great quantity of video work each year (from an outside production firm) and the clips provided are beautiful in quality and small in file size -- for example, I recently worked on a video and got it into the 40MB range before quality went to crap, working off the same material the production company we do work with had theirs down into the teens and looking beautiful!
    To throw an even greater wrench in the works, I am working off a mac. But when my boss, on a pc, saves the mp4s I create (raw files -- not what is posted to the web) locally on his machine and views them from there the sound is always off a tad and the people in the videos look like they're lip synching.
    Any advice on either of these is MUCH appreciated. I've been trying to figure this out properly for months, and only today decided to stop seeing if someone else had the same question and just post my own.

    Thank you Karsten, this was helpful I have utilized the Quality slider and the frame size options before though with limited results. I've never messed with the Limit Date Rate option as I don't know what I'm doing with it, I see you put 5Mbps. Is that a typical setting that I could use?
    Using stream info, here's info on my original source file:
    Stream: Charles_0023_2.mov
    Duration: 0:00:51
    Data Size: 96.51 MB
    Bit Rate: 15.77 Mbps
    Video Tracks:
    H.264, 1920 × 1080, 29.97 fps, 15.64 Mbps
    Audio Tracks:
    MPEG-4 Audio stereo, 48 kHz, 127 kbps
    Stream Files:
    Charles_0023_2.mov (96.51 MB)
    As a comparison, here's the info on a similar clip that the company we sometimes use created:
    Stream: Charles_0019_4.mp4
    Duration: 0:00:49
    Data Size: 4.66 MB
    Bit Rate: 0.80 Mbps
    Video Tracks:
    JVT/AVC Coding, 710 × 400, 29.97 fps, 635 kbps
    Audio Tracks:
    MPEG-4 Audio stereo, 48 kHz, 162 kbps
    Stream Files:
    Charles_0019_4.mp4 (4.66 MB)
    I'm fine with bringing the frame size down some and modifying the limit data rate, but sometimes I feel like I'm forcing my video into something it's not and the quality suffers -- this is where my understanding of video work breaks down LOL. Any suggestions of how I can get my .mov into something like the the .mp4 above?
    Also have you had any experience with mp4s not playing back properly on pcs?
    Again, thank you!

  • Need help with Export workflow.

    Hello again.
    Today I was experimenting with exporting a project using Export QT Movie and QT Conversion.
    My goal is to show a QT project on the web, either 640x480 or 320xx240, depending on how monstrous the file size is.
    My initial impression was that export QT Movie simply generates (I'm guessing) a full size rendering of the project. It's icon is a FC icon. What I did then was an "Open with..." quicktime(pro). This is where I get confused: I know that the next steps are for for preparing the project for sizes, compressions and so on. The export to QT movie seems to be a longer route to get to the settings that you need to use in QT Conversion, which after selecting QT conversion, you have the Format, Use, and Options settings.
    Am I right so far?
    Some background about my project- Easy setup= DV-NTSC. If I look in my browser, my clips are 720x480, 29.97fps, Compressor(?)DV/DVCPRO-NTSC, pixel aspect ratio, NTSC-CCIR 601 and anamorphic is checked.
    I also have still photos motion control stuff, PS tiffs, that do not have anamorphic checked.
    Form here on is where I get confused.
    Under settings, I am selecting DV/dvc-NTSC for compression frame rate 29.97, medium compressor, scan mode, interlaced, and aspect 4:3.
    The filters setting I don't use.
    The size setting I'm trying 320x240 with aspect ratio and de interlace video UNCHECKED.
    Is this a good workflow for the web. I notice on 640x480 my titles (livetype) seem kind of jagged.
    Any help preparing a project for the web would be appreciated. If you need more info let me know.
    Thanks so much.
    Jonathan

    Thanks for the additional comments and ideas.
    In terms of profile, as I mentioned, the intermediates will be going off to the editor (off-site) for editing on his FCP suite.  I'll stick to working in the prescribed HDTV (Rec. 709) space, and I've given him all the detail I can of how I'm working, but crucially I haven't stood at his edit-suite to see how the stuff looks.
    But, he's no newbie, so I'm hoping it'll be OK.
    Blasted shame about the H.264 BluRay not being compatible with QT - I thought I had this whole issue beat until that came along.  It's not a matter of disk space here, but the editor is mithering that the intermediates we are testing, in either PNG, or Animation, and a couple of others, are choking his playback.
    I'm not sure what to say about that, other than to go down this road of trying to squish these intermediates as low as possible without wrecking the look, hence finding that the DNxHD is providing the best solution.  If it had been a SD project, I might well have tried the native H.264, even over our normal PNG workflow.
    So what will play the native H.264 BluRay compressed output?
    Julian.
