How to reduce oracle DB's size?

Hi,All
After upgrading NW7.0 to NW7.0 EHP1, the oracle's changed from 37GB to 70GB, How to reduce the DB's size?
Thanks.
Best regards

Hi,
1.From DB02--> detail analysis menu you can take out top 50 tables & indexes. you can mark the size of the index should be generally less than the table.If its more or very much similar size of table, you can rebuild it using SE14. This can free some space.
or else you may use brspace to do this.

In case of table this option is risky as it may result in data loss.
2. Earlywatch alert gives the top 20 degenrated index. you can check that which also gives a factor 'storage quality'.
3. Run report SAP_DROP_TMPTABLES. It removes temporary database objects. ( we do this in our BW system)
Hope this helps
Thanks

    My AI file size was not going under 1 MB even by deleting extras so what I did is I opened a raster small image of 100 kb with Adobe Illustrator. then deleted the image and saved the file as AI. Then I Copied the whole vector content of original AI file that was bigger then 1 MB with ctrl+c command and pasted it in the new file created with raster image. and saved it. Wow the new file size is only 137 kb now.

    I've found in Pdf's many time when you go to Optimize a PDF and look at the font list there are often up to a 1/2dozen copies of a given font, say Helvetica, then that many Helvetica Bold, or Arial or Ariel Italic
    What I do ie remove from list all but one copy of each different font. often dramatically reduces the size. also something lese is Flattening images will in some cases reduce a file size. I have run into a case where it actually made a PDF Larger.

  • How to reduce max buffer/cache size?

    Hi,
    every time I copy a file which is bigger or similiar in size to my total RAM (4gb) I notice very low responsibility from firefox (which is totally unresponsive, can't switch tabs or scroll for 30-60s). Of course my free memory is very low (something like 50-100mb) and I notice some swap usage. AFAIK linux caches everthing that is being copied, but in case of such big files it seems unnecessary.
    Is there a way to reduce max buffer size?
    I know that buffering is good in general, but I get a feeling that firefox is giving up ram and he has to read everything again from disk which slows him down. I always have many tabs open, so often it has around 30% of memory.
    I searched many times on how to reduce buffer sizes, but I've always found only articles with "buffering is always good and never an issue" attitude.
    I would be very happy to hear any suggestrions,
    cheers,
    kajman

    This seems a popular problem, going back years. The default Linux setup is bad for responsiveness, it seems.
    Here's the summary of what I do:
    Firstly, install a BFS-patched kernel, for a better kernel scheduler, and also so that the ionice and schedtool commands will work. Bonus points for switching to BFQ while you're at it - or stick with CFQ, which also supports ionice.
    In /etc/fstab, use commit=60 rather than default of 5 seconds, and also noatime, e.g.:
    UUID=73d55f23-fb9d-4a36-bb25-blahblah / ext4 defaults,noatime,nobarrier,commit=60 1 1
    In /etc/sysctl.conf
    # From http://rudd-o.com/en/linux-and-free-software/tales-from-responsivenessland-why-linux-feels-slow-and-how-to-fix-that
    vm.swappiness=0
    # https://lwn.net/Articles/572921/
    vm.dirty_background_bytes=16777216
    vm.dirty_bytes=50331648
    In ~/.bashrc - see post, e.g.:
    alias verynice="ionice -c3 nice -n 15"
    In /etc/security/limits.d/ - see post. Read CK's excellent blog article, for info.
    In your cp command, add the word verynice to the start, to stop the large batch copy from having the same priority as your UI.
    Compile sqlite without fsync, to make e.g. firefox smoother.
    Potentially use threadirqs to prioritize the interrupt-handling.
    Edit: Updated vm.swappiness from 0 to 10, from CK's blog.
    Edit2: Also see patch and e.g. nr_requests in thread.
    Edit3: Using nice instead of schedtool - not sure whether schedtool can hog the CPU.
    Edit4: Added threadirqs.
    Edit5: Tweaked sysctl.conf settings.
    Edit6: Added nobarrier option to mount, and sqlite's fsync.
    Edit7: Removed swap comment - I do use a swapfile, these days, mainly because firefox needs so much virtual RAM to compile.

  • How to get oracle table occupied size

    Hi,
    Actually my task is arrange to get an oracle table occupied size for a particular schema.
    I have an query to get allocated table size,the query as follows
    SELECT SEGMENT_NAME,sum (BYTES)/1024/1024 FROM user_SEGMENTS WHERE segment_type='TABLE' group by segment_name order by sum(bytes) desc;
    But actually i need to get "how much space occupied for each table in that particular schema"
    Thanks in advance...............

    Do you want this?
    SELECT t.owner, t.table_name, t.tablespace_name,
    (sum(d.bytes)/1024/1024) table_size
    FROM dba_segments d, all_tables t
    WHERE d.segment_name = t.table_name
       AND d.segment_type = 'TABLE'
       AND t.owner = 'SCOTT'  --- you can change or delete this condition
    GROUP BY   t.owner, t.table_name, t.tablespace_name;

  • Reducing oracle data file sizes to a bare minimum

    Hi,
    How can I create an oracle instances with minimal file sizes ?
    Using the database configuration wiz, i've specified 10~20mb sizes for SYSTEM01, UNDOTBS01 etc. but when the instance is created the files were still huge :
    SYSAUX01 was 83MB,
    SYSTEM01 was 256MB
    UNDOTBS01 was 158MB
    The only files that seems to have complied were the redo log files.
    It's a testing environment that's constantly restored so i'm trying to fit the files into a ram-disk (using imdisk) in favour of performance.
    The data required/created by each test is not large and because it's only a testing db reliability/consistency is not an issue - rollbacks are also minimal (i've set the retention at 15 secs so far)
    So if anyone can shed some light on how to keep filesizes to a minimal, I'm all ears.
    If there's a way to run without some of these files, i'm keen to hear too =)
    Thanks

  • How to reduce image's file size in Preview?

    I am in Preview Version 5.0.3 (504.1).  I have a PDF file that is 3.7 meg. in size.  That is a big large for what I want to do with it.  I would like to reduce its size to something a bit more manageable.   The Preview Help gives these instructions:
    To reduce an image’s file size without changing its dimensions:
    Choose Tools > Adjust Size.
    Select “Resample image.”
    Enter a smaller value in the Resolution field.
    My problem is that in my open window for this file the "Adjust Size" tool is dimmed.  I cannot choose that tool as instructed.  
    Does anyone know why and how to get Preview to reduce the size of a PDF file?

    try File-Save As...
    & choose format:pdf    quartz filter:reduce file size
    pick another name to check the results - there's no undo

  • How to reduce Oracle ADF Mobile deployed file

    Hi
    I'm creating simple demos with Oracle ADF Mobile and the deployed file is more than 50mb. Is there a way to reduce this size? Maybe remove some unused features llike SQLLite?

    My simple demo IPA files have been around 20MB with the default splashscreens and such, the only time it was bigger was when some files mistakenly got included. You could always load resources on-demand the first time over http and cache them in the app documents. This way you could only download the graphics for the current platform (so if it's a phone, you don't download iPad banners and graphics that your app needs)

  • How to reduce PDF Form file size?

    Hello
    I have a PDF that is 22KB without form fields, but once I add the fields to the form, it increases the size to a huge 528KB.
    There are 5 or so text fields, one digital signature, and 14 different 'Radio Button" categories.
    Is there any way to still ensure the form works as I need it too (ie. I don't want to get rid of any fields, and I don't want to change radio buttons to check boxes or anything), but reducing the size of the file??
    Thank you

    Are you using any font's other than the standard ones (aka base-14)? The standard ones are Helvetica, Times, Courier (including four variants of each), Symbol, and Zapf Dingbats (Adobe Pi is the replacement).
    If that's not it, do a Save As, as opposed to just a Save. This will rid the document of unused objects that accumulate each time you save.

  • How to reduce/increase search webpart size

    How to change the size of the search webpart. When modyfying the webpart, there are two options for defining the height and width of the webpart, but when changing those porameters, only the zone size increases..the webpart size remains the same.. is there a way to change the size of the webpart..(increase or decrease the size of the webpart?)
    Thanks in advance..

    Moving to Design/Customization as the fact this is a *search* web part seems less relevant than the fact you want to change the size.WSS FAQ sites: http://wssv2faq.mindsharp.com and http://wssv3faq.mindsharp.com

  • [Schema Design]: How to reduce inventory snapshot table size

    We are planning to store inventory level's periodic snapshot at the end of each day. We have close to 50k different products. 
    But on a given day only 5-6k products inventory changes. 
    As I understand if I start inserting just the products which have changed inventory, analysis around semi-additive dimension (Quantity) doesn't work properly. 
    For better understanding, lets take say the fact table looks like:
    product_id     time_id     quantity
    1                         1             100
    2                         1             130
    3                         1             100
    1                         30           200 
    So basically, it says product 1,2,3 from time_id 1 to time_id 29 doesn't have any update in quantity. But product_id 1's inventory changes to 200 on time_id 30.
    This approach reduces fact table size by approx 90 rows.
    My question is, is it a good idea? Would this semi-additive dimension still give the same result (I doubt though)?
    If not, then what other approaches I can take?
    Thanks in advance.

    Another option is to capture just the net changes (sometimes referred to as a journalized fact table). Then you can create a calculated measure that sums all the changes from the beginning of time up to the current time-slice.
    This may seem like an inefficient solution, but there are ways to reduce the problem by limiting the history for which inventory snapshots are available. For example, if the business only needs snapshots for the past 90 days, then you can grab a snapshot
    of inventory for all products on day 0, and then capture the net changes for each product for days 1-90. Then you can calculate the snapshot in time by adding the baseline snapshot to the sum of all net changes.

  • How to reduce the swf file size of an imported After Effects file

    Hi!
    I am trying to make a web banner for an internet marketing company, so it has very specific requirements. We had it made in After Effects, and I was able to export it as a FLV file and import to Flash just fine along with the SWF. Now, I need to make the SWF file significantly smaller.
    Right now it is 2.5 MB and we can only submit a 40K size SWF. Is it even possible to reduce the size so much and still keep the animation's intregrity?
    I am more familiar with Flash than After Effects, but can play around with settings, etc if someone can tell me what to try.
    Thank you for your help!

    the easiest way to load and play your flv is to use an flvplayback component.  you just drag it from the component panel to the stage and, in the properties panel, assign its properties (eg, skin and source).
    but that will probably put you just over your 40kb limit and will require the skin.swf to be placed on the server with your banner ad.
    to decrease your swf size to negligible, use actionscript to play your flv.  this is the barebones code needed.  just replace your_video_url.flv:
    var nc:NetConnection = new NetConnection();
    nc.connect(null);
    ns:NetStream = new NetStreamnc);
    ns.play("your_video_url.flv");
    var video:Video = new Video();
    video.attachNetStream(ns);
    addChild(video);

    Darryl's suggestion is the best first course to reduce the image size. You might also experiment with reducing the color depth (e.g. - 64 million colors-> 256 colors/16 colors) of the images - which works particularly well for GIF (almost mandatory) or PNG - though it is relatively pointless for JPEG.
    BTW - adding dukes indicates 'interest level', but adding '4 dukes' indicates the problem is not very important. Do not expect me to make a second post on this matter unless the dukes are raised to '10' - I don't have the time.
