One single tablespace for the entire db of 3.3T

One of the db i am supporting has about 3.3 Terabytes capacity and the application is using only 1 huge tablespace with one big file.
the system is linux 4 , 32 bit.
oracle version is 10.2.0.4
Is there a limit of space for a tablespace when you consider insert/delete/query performance?
Thanks,
Chau

It's really depends on how your storage been setup. Besides the lack of parallel backup ability like other user pointed out. There shouldn't be any other major performance impact solely because of big tablespace. Or bigfile tablespace alone doesn't cause performance problem. It's only a problem if you setup is wrong. For example setup this file on system that doesn't support striping.
Since you have 3.3 TB size tablespace with one single datafile, that means you must have a big file tablespace which only support one datafile.
Performance of database opens, checkpoints, and DBWR
processes should improve if data is stored in bigfile
tablespaces instead of traditional tablespaces.
However, increasing the datafile size might increase
time to restore a corrupted file or create a new
datafile.That is in the event of media crash, that could be only affect one or two small files in traditional setup, but in your case, you need to restore whole big file.

    We have 4 iphones and an Ipad in our family. When we purchase music, I would like for the entire family to be able to use it and then back it up to Icloud. What is the best and cheapest way for this to happen.  Should we all have a different apple id or should we use the same one.

    You will all need to be on the same itunes account ID.
    You can however all have seperate icloud accounts aswel.

  • HT1660 how can I use one single library for all users on the same laptop?

    how can I use one single library for all users on the same laptop?

    You are most of the way there. Each user having access to hard drive is the key. If users are limited in file privileges this is harder.
    Any files you add to your library and any files she adds to her library are available to the other. Just not automatically. Each user must add the files to their own library using the add file or add folder option from menu bar.
    What I have done is set library location to a location outside of My Documents\My Music. On my network storage I have a folder names s:\itunes. Both accounts iTunes are set to use this location for the library.

  • Reporting annoying issues for the entire Microsoft website (MSDN, forums, all)

    Is there any place where I can report bugs with how the Microsoft web sites behave? I can only find forums and "Microsoft Answers" categories about single products that Microsoft makes, but nothing about the infrastructure itself.
    For about two weeks now, I am required to log into my account every few hours whenever I access any Microsoft website. This includes MSDN help content, forums, or other resources. I need to login after opening the website through F1 help in Visual Studio
    as well as accessing a microsoft.com link from anywhere else like a web search or a direct link from web or an application.
    Auto-complete does not work either. My browser (Firefox) does save the password, but it never fills it into the form. Other people have already noticed that
    Microsoft applies some dirty tricks here. And even if the login is remembers for a moment, it's slow as hell. It takes a second or two to load the login.live.com page (which is not what I wanted to see), then it sits there for some more seconds before going
    anywhere. Other login services like Google or StackOverflow manage to log me in all within one second and most of the time I don't even see it.
    And then there's still that insecure SSL-to-non-SSL-submit warning that only occurs in other browsers then IE. Has anybody cared about that in the last couple years?! I'm not getting it now, probably because I'm not logged in anymore. It all slowly falls
    apart, piece by piece. Next step is probably losing my data or not loading it at all.
    THIS – IS – ANNOYING! And it really makes me feel like I don't want to use Microsoft products anymore (because even good desktop applications are connected to that silly website). I have opened a
    Microsoft Connect ticket for a part of this issue (it's grown bigger since then), but this ticket is totally ignored. If microsoft.com went down, they'd certainly care within minutes or hours. This bug is not even regarded in
    weeks!
    So do I have to write a postal letter to the president of the whole company or do they have support staff for that?! Do they have anybody who is capable of maintaining their website? It's really frustrating how Microsoft has a web presence that is worse
    than what our first-year trainees come up with. It's full of bugs and this is currently only the most relevant one. Do they even care about how the world sees them? Or is Microsoft currently preparing (and even failing) to move out of business?

    My database is OLP system.
    My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
    Easy to maintain when you have single tablespace. but hard to track the IO issues.
    Any other input from any one? Please let me know.

    Does the term "keeping all your eggs in one basket" mean anything ....Well, in the majority of cases, even when using multiple tablespaces they will be on the same storage array or same file system. So the "+all eggs in one basket+" goes a lot a deeper down the storage layer than just the top part where you deal with logical tablespace storage containers.
    Absolutely. Except for the bazillion microscopic solid-state switches and a layer of rust on a spinning platter, everything else is just layers of abstraction. One's thinking and frame of reference depends on what layer of abstraction one is dealing with.
    The major problem with multiple tablespace for a single application And here is where there was some 'fuzz' in the OPs question. I don't recall him specifying one TS per application. Maybe he assumed that, but I read it as one (user) TS per database.
    a) deciding the space allocation of each tablespace
    b) managing what is created in which tablespace
    This comes down do an issue of micro-managing space versus simply chucking everything into a single container and let god ASM/Oracle/LUN/driver/whatever sort them out.
    Issues like transportable tablespaces... separating your logical data into different containers... and the like? That is not really sufficient justification to me for having to micro-manage space for a 101 tablespaces. This simply creates a huge workload on the space management part of the database - that is complex and difficult to deal with. Free space from an underutilised (incorrectly sized) tabelspace cannot simply be moved and reallocated to a tablespace stressed for more space. Everything but...
    Which is why I prefer having fewer tablespaces as this means not having to micro-manage space and continually having to wave a threatening lead pipe around to make sure that applications and developers play rigidly within the large set of strict rules of how these many tablespaces are to be used.Agreed. One can go way overboard, and a lot of this discussion hinges on the OP's intent, as I mentioned above -- one TS per ... what? My default position is one TS per application schema. Normal human users all default to one USERS ts, but don't have any quota because they don't have any reason to create objects.

  • Merging two records in a single record for the same matnr,werks and bwart.

    Hi I have a requirement to merge two records into one single record using the quantity field from MSEG table.
    I am selecting two records from the table MSEG. Now for these two records i have to add the quantity values into one variable.
    Then there should be only one record for the same matnr,werks,bwart.
    Any suggestion would be appreciated.

  • How to set the icon for the entire application with JFrame.setIconImage

    I set the icon on the main frame using JFrame.setIconImage(). The icon is shown properly in the main frame.
    If more JFrames are opened from the main frame, the newly opened JFrames also show the icon.
    However if JDialogs are opended, in some cases the icon set on the main frame is shown and in other cases the coffee cup.
    What is JFrame.setIconImage() expected to do? Setting the icon for a single JFrame or the entire application?
    How can I set the icon for the entire application?
    How can I set the icon for JDialogs?
    Thank you

    In order for your dialogs to use the same icon as the frame, you must parent the dialogs to the frame which has the custom icon.

  • Adding music to more than one slide and not the entire presentation

    I love the way Keynote looks and behaves, but it fails to compete with PPT on certain aspects, such as adding the same audio track to more than one slide and NOT have it play for the entire presentation. Using PPT (and I hate PCs!) you can have a track play for "n" number of slides. I'm frustrated that I cannot do this with Keynote! I don't want the track as a soundtrack for the entire presentation. I want to add another audio track to, say, the last two or three slides only and something else for all the other slides. I looked through the user manual, forums, etc. and found that I can only add a soundtrack to the entire thing or a different audio to only one slide.
    Question: What if I cut (that last two slides) and paste the the slides as a new Presentation with its own soundtrack, then reincorporate that back and paste it into the original presentation? Will that work or will the original soundtrack take over the entire presentation again?

    Anyone remember Claris Works for Mac back in the early 90s? Now, that was a gem! What were they thinking when they got rid of that one (and replaced it with AppleWorks!)?
    Good point, but one which Apple has heard a zillion times, and so sadly chosen to ignore. The really heartbroken among us remember AppleWorks from the mid-'80's, the world's first integrated suite, then ClarisWorks, then AppleWorks; and, of course, Beagle Bros. and BeagleWorks. But since we old f*s are dying off, those complaints will eventually stop. +Sic transit gloria mundi.+

  • Can't get burned CD to be read on my laptop itunes which I'm trying to transfer music to. It just says 'track 1' for the entire CD, and can't be copied. Says unknown error -50 when I try to import. Any ideas?

    So...I'm trying to transfer my itunes music to my laptop. I set up a new itunes on my laptop and, with great difficulty (I'm not technical), I've managed to be successful with the help of my memory stick, which saves wasting CDs.
    However, for some reason a few tracks by a couple of artists don't seem to have transferred. So I had the idea to burn a CD and then copy that directly to my laptop.
    There doesn't seem to be any trouble burning the CD - that works fine. I just select audio CD, and done within a minute or so. But when I then put the CD in my disc drive, it doesn't work.
    It says 'track 1', with no other tracks for the entire CD. When I try to import it, it says 'unknown error -50'. I've tried tinkering with the import settings, but it makes no difference.
    Does anyone have any ideas?
    I'm not that computer literate, so please make it idiot proof

    You can use the bootstrap tar.gz files that are found in the same directory as the iso on every mirror.  If you go to the download page, select the mirror of your choice, you will see a file called "archlinux-bootstrap-2013.10.01-x86_64.tar.gz" (one for i686 also).  That is what you need.
    Unpack it whereever you think is appropriate, if you have enough RAM you can use /tmp.  Then after setting up the partitions in the host (Kali/Debian, or whatever), you can arch-chroot to that unpacked directory.  There you will find all the tools necessary to install (pacman and the arch-install-scripts).
    This method has one issue though, and that is that the arch-chroot script (and maybe others) requires some pretty new versions of various things.  In particular, I think that a pretty new version of bash is required.  So I am not sure about the viability of this solution on anything debian, as their stable repos tend to be pretty conservative.  It also means that you need to have a pretty good understanding of the install process, as you will still mostly follow the beginners guide, but it will require a few changes in the procedure.
    Good luck.

  • Enter more than one personnel number for the same confirmation in CO11N

    More than one labor working on Machine work center simultaneously.

  • If this is the first time you received this mail, it contains the history for the entire month

    HiYa,
    this is the message I get when I try to  send a message from my website created with Adobe Muse and uploaded via FTP:
    "Form PHP script is missing from web server, or PHP is not configured correctly on your web hosting provider. Check if the form PHP script has been uploaded correctly, then contact your hosting provider about PHP configuration."
    I know this is an old issue but there must be a solution.......
    Apart form this message I get as well in my mail this one:
    Note: If this is the first time you received this mail, it contains the history for the entire month so far.
    Below are the recently upload scripts that contain code to send email.  You may wish to inspect them to ensure they are not sending out SPAM.
    /home/thepixel/public_html/scripts/form_check.php:108:           {

    /home/thepixel/public_html/scripts/form_check.php:110:                if($sent)
    Can anyone help me..?   thank u very much

    That is not entirely true. Mues does generate PHP files when you use the formular widget.
    Furthermore, it generates a file named form_check.php which is apparently meant for checking the server-configuration. The file even attempts to send testmails to the adresses seen in the OP.
    Sadly, this file is completely unsecure and can be called by anyone who knows the name.
    Hence this file can very easily lead to errors and spam-warnings from your provider.
    Until Adobe decides to fix this or to atleast warn users about the existance of that file, I suggest you add the following lines  to a .htacces file on your server:
    <FilesMatch "form_check.php$">
    deny from all
    </FilesMatch>

  • Why did the App Store bill my debit card for the entire app fee when I had money on my account?

    I bought a Music Studio app recently that costed $15 and I had $15.04 on my account. I was aware this wasn't enough for tax, so I tried to use a debit card when it said I had insufficient funds. After the process, it took no money off of my account, but billed the debit card for the entire fee. Can I get this payment rearranged? Or a refund?

  • Batch Split in OBD & billed for the entire Quantity .RG1  register does not update the excise values

    Hi All,
    I am new here . We have batch split in Delivery and 601 happens for the individual batches and billing we bill for the entire quantity . Hence the RG1 does not update the excise values for the batches and it is showing as zero (upon extraction in J2I6). Upon research through the program the latest note which i presume is patched
    The latest note is N158234 which does not show in the program but seems have been patched considering we are using the Latest version of SAP .
    As you see above in the billing we have billed for the whole quantity but RG1 does not update for the since the batches are zero .
    My programmer says because of some note related to cancellation where it says about values H & J in vbfa table and due to which program does not go through the Note for the batch split .
    Now i have checked few other projects in my company and they all seems to be following the program . So i am wondering whether my process or some customization is missing .
    Sales order (no batch determination)  , in delivery the batches are picked through wm to and batch split happens in the delivery . Then billling for the whole quantity . We have automatic excise invoice creation enabled so no J1IIN .
    Can somebody help me .
    Thank you

    My programmer says because of some note related to cancellation where it says about values H & J in vbfa table and due to which program does not go through the Note for the batch split
    Which field (H & J) they were referring in VBFA ?
    i have checked few other projects in my company and they all seems to be following the program
    How about the other projects' values in VBFA where your techinical team is guessing some issue.  Have you compared this?
    Since you have already the note 158234 implemented in your system, ideally, you should not face any issue.
