Move single tablespace

Running Oracle 10gR2 on RHEL 4
Just wondering if someone can give me some insight on how to move a single tablespace from PROD to TEST. We use Noetix and would like to move the Noetix tablespace from our production (PROD) environment to our test (TEST) environment. Would this be best achieved with RMAN? Datapump? Typically I refresh the entire database, but I've never moved a single tablespace from one environment to the other so this is all new to me.
Thanks!

  • Clubbing of datafiles in a single tablespace

    hi,
    i have 4 datafiles each of 2gb in size in a single tablespace.. i would like to know is it possible to club these four datafiles in to a single datafile..and is there any limitation for the maximumsize for the datafile in 32bit version..
    thanks in advance

    Hi
    To put all your data into one data file you will have to create a new tablespace with one 8 GB data file and move all your data to the new tablespace.
    The maximum size of your data files depends on the block size of the data file and the type of tablespace you create. In 10g you can create a big file tablespace with 1 data file with no size limit. For a normal small file tablespace with an 8K block size the limit is 32 GB per file. For a 16K tablespace, the limit is 64 GB per file. The amount of files in your tablespace is only limited by the MAXFILES value that is specified when you create the database and that is stored in your control files. To change the value of MAXFILES you have to recreate your control files.

  • Is There a Way to Run a Redo log for a Single Tablespace?

    I'm still fairly new to Oracle. I've been reading up on the architecture and I am getting the hang of it. Actually, I have 2 questions.
    1) My first question is..."Is there a way to run the redo log file...but to specify something so that it only applies to a single tablespace and it's related files?"
    So, in a situation where, for some reason, only a single dbf file has become corrupted, I only have to worry about replaying the log for those transactions that affect the tablespace associated with that file.
    2) Also, I would like to know if there is a query I can run from iSQLPlus that would allow me to view the datafiles that are associated with a tablespace.
    Thanks

    1) My first question is..."Is there a way to run the
    redo log file...but to specify something so that it
    only applies to a single tablespace and it's related
    files?"
    No You can't specify a redolog file to record the transaction entries for a particular tablespace.
    In cas if a file gets corrupted.you need to apply all the archivelogs since the last backup plus the redologs to bring back the DB to consistent state.

    2) Also, I would like to know if there is a query I
    can run from iSQLPlus that would allow me to view the
    datafiles that are associated with a tablespace.Select file_name,tablespace_name from dba_data_files will give you the
    The above will give you the number of datafiles that a tablespace is made of.
    In your case you have created the tablespace iwth one datafile.

  • Single tablespace or full database in 10g

    Hi,
    Which is the best regarding performance...what ever it may be...when doing hot backup...which is the best in all ways..
    (a) putting single tablespace in backup mode and copying
    or
    (b) Putting total database in Backup mode and copying...
    can anybody sched some light on this..in all ways..

    The best is to stop using paleolithic backup techniques and use RMAN with Block Change Tracking.

  • How to move a tablespace

    What are the steps to move a tablespace?

    You can go through this link in Oracle documentation :

  • No of Datafiles needed in single tablespace ?

    hi,
    i have one tablespace of size 120gb with 23 datafiles in which first 19 datafiles are size with 2gb each. and rest data files are size with around 28 gb.
    Recently i heard that by keeping more no of datafiles will affect the performance of Database . so my question is what are the advantage and disadvantage of keeping more no of
    datafiles in single tablespace and how can i merge small data files of 2 gb ?
    Regards,
    Mithun Mathew
    Oracle DBA

    After going through couple of links provied by google i made a note on this issue :
    Optimizer does not consider number of data files when selecting execution path. Also as a general rule, you do not deal with I/O performance at tablespace level. You cannot stripe the contents of a tablespace across multiple datafiles. This need to be dealt with at a lower level (like inside Oracle ASM).
    Advantages: (More Datafiles)
    1.By using more than one datafile per tablespace, you can spread data over many different disks to distribute the I/O load and improve performance.
    2.Easy and faster restoration and recovery. The more datafiles for a given amount of data, some recovery scenarios will be faster due to having to restore/recover a smaller file.
    3.Less chances of encountering 2gb
    issue.(http://www.fors.com/velpuri2/Oracle%20block%20structure/2gb)
    4.Having multiple datafiles per tablespace facilitates the adoption of a uniform datafile size policy, which in turn facilitates disk load rebalancing.
    5.For file system based databases, having multiple datafiles may reduce the risk of contention for the operating system's datafile read/write locks (inode locks).
    6.If any corruption happens in a datafile, then there is less data loss chances in compare to one or less datafile.
    Disadvantages: (More Datafiles)
    1.We can not have BigFile Tablespace's advantages.
    2.Tough managebility and portability.
    3.Putting tablespace offline will offline all the datafiles, which will stop other applications/of its parts unnecessarily.
    4.More datafiles for DBWR for writting and more files for RMAN to backup.
    5.Many datafiles are opens when we online tablespace; means many file handlers for OS at kernel side.
    6.We have to carefull to create rollback segments because, never create rollback segments using multiple datafiles within a single tablespace.
    7.The more datafiles, the more time required to do checkpoints and such, because every file has to have its header updated.
    8.More entries in data dictionary, control file entries more file structs in SGA vs less or 1.

    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.

  • Use of backing up a single tablespace or datafile

    Hello,
    I am reading the RMAN manual and I'm quite familiar with backup up a tablespace or datafile, but I can find very few uses for that. Backup up a tablespace is useful for TPITR, but since that needs another instance its of very little use in most production environments. I think you cannot restore an old version of tablespace in a normal database, unless the tablespace has long been made read-only, in which case RMAN's optimizations will do the trick.
    Even less use I can find for datafile backup. I have absolutely no idea what you can do with a single datafile.
    Can you please clarify me on the uses of these RMAN features?
    Thank you.

    Dear Albi!
    Think of the following scenario:
    You have a very large (let's say 1 Terabyte) production database that is split into n tablespaces. This database is in archivelog mode and a full backup of the hole database would take more than 10 hours.
    scenario end.
    In such a scenario I think you will not take a full database backup very often. Therfore you can backup portions (tablespaces and datafiles) of your database. This will take less time then a hole DBbackup.
    If you have to restore your DB then RMAN will take all the files it needs from all your backup. RMAN uses always the most actual version of your datafiles. After the restore RMAN will take the archivelogs to recover all datafiles to the most actual point in time. And that's the point why partial backups of your db are not only usefull for TSPITR.
    I hope I could make clear what the operative point is with partial backups.
    Yours sincerely

  • 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.

  • Export vertical oriented movie single frame - not working

    Using:
    - iMac 20" 2 GHz 4 GB RAM
    - OSX10.5.8
    - iPhoto 8 version 7.1.5 (378)
    - QuickTime Player Pro Version 7.6.9 (1680.8)
    - Preview 4.2 (469.5)
    Here is what I do to export a frame from a move in iPhoto to get a single frame:
    Open and play a video in iPhoto using Quicktime Pro, stoping and selecting a particular frame, pressing Command C, open Preview, select New From Clipboard.
    or
    Open and play a video in iPhoto using Quicktime Pro, stoping and selecting a particular frame, Selecting File Export Move to Picture.
    Both the above work for horizontal oriented movies.
    However, for vertically oriented movies neigther works.
    Movies are taken with:
    - iPhone 3GS
    - Exaxti CG6
    - Insignia NS-DSC7B09
    - Fujifilm Finepix XP20.
    Any solutions/suggestions (except upgrading to the newest iPhoto, Lion, etc. too slow on a 2 GHz iMac)
    Thanks.

    I mentioned in the second part of my initial post that I did also try the export "Movie to Picture" with the same results.
    Strange! That work flow still works on my PPC platform. (Unfortunately, I don't have an Intel platform available with OS 10.5.8 installed for testing.)
    Am I able to have "MPEG Streamclip" open as the default when a movie is double clicked on in iPhoto instead of Quicktime opening the movie?
    Not sure. I don't use iPhoto (prefer Aperture) normally and definitely would not use either for video clip management. Try resetting the double-click external edit switch or reset the "Open With" atribute for the class of movies being edited.
    This actually for a novice user who I suggested take short video clips, pick a frame then copy/paste it into Preview instead of taking stills. Unfortunatly my advice fails when the iPhone photos are taken vertically.
    The problem may be based on a change on the application being use. Like anamorphic videos with contain both pixel dimensions and PAR values, the reoriented videos may contain both true orientation and display orientation information. How the files work may depend on the application being used at the time. I.e., some third-party video/still display apps rely on the original orientation while others use the "rotated" info embedded in the file. And, unfortunately, it appears that Preview does not know what to do, so it does nothing. My guess is this is a bug that needs to be reported in feedback to Apple again and again until until they decide to address and correct the Preview application.

  • Move single instance db to RAC10g2 - the best choice ?

Option 1) Best method would be using RMAN to take backup from old server and restore it into new server. I'm assuming version of oracle to be same i.e 10.2 and OS is also same.
    The effort is required a little bit higher then you do for IMPORT/EXPORT of database using DataPump.
    Option 2) Use physical standby database setup if migration time is supposed to be very low. I hope you know how to achieve this
    Option 3) Use goldan gate to migrate data from old to new, if migration time is nearly zero.
    And ofcourse you would be doing following:
    1) Install and configure Cluster
    2) Install oracle database software

  • Two versions of same movie - Single icon?

    After creating an iPod version of a movie, can I get iTunes to display only one version? ie AppleTV and iPod version, but single title displays (different resolution)

    What you're trying to do is Duplicate the first project, then make changes. Depending on which version of iMovie you have it might be this easy. Go to the Project Library. Hold down the Control Key and click on the project. In the pop-up menu there's an option titled: Duplicate. That will give you the second movie you need to alter. Duplicate once more to get number three ready to go.

  • Cannot move single pages

    hi everybody,
    i am turning crazy by this. I have a finished 7 page document in front of me. now i'd like to move the 6th page in the 2nd spot - however pages won't let me do that.
    when trying to select the miniatures it shows me a yellow rectangual border and around them and i can either edit/duplicate/etc. all 7 pages but no single ones.
    what's the deal?
    thanks
    lukas

    lukas,
    You figured out my instructions even though I must have been half asleep and even on the second try gave you some misinformation. Where I said Page Breaks, I meant Section Breaks of course. So the lesson is to not try to give directions when I'm rushed, tired or trying to do more than one thing at a time.
    The bottom line for you is to use Section Breaks to isolate content so that it can be manipulated in the Thumbnails pane. Since content won't flow past a Section Break, further editing can result in pages that end well above the bottom margin. The solution is to remove the Section Breaks that you no longer need if you have that problem.
    Regards,
    Jerry

  • Getting error in remapping to single tablespace in transporable tablespaces

    I am running oracle 10g release 2, Solaris 10 on sparc machine
    I want to transfer data using transportable tablespaces. I am using Oracle data Pump for this purpose and want to remap all the tablespaces on my source database to one tablepace on destination machine.
    To do this, when i included the following clause in my import (impdp) statement.
    REMAP_TABLESPACE=A:STORY,B:STORY
    It correctly maps schema A, but when it goes for Schema B, then I get the error that tablespace already exists.
    Is there any way to avoid this error.
