Unable to reclaim free space

tablespace size: 62G, 14 4G files and 1 6G file, freespace =51G
When I try to resize datafiles, I get an error; the max free space per file =1G --- not sure what is using up the space.
environment: 10.2.0.3 2-node RAC cluster on Red Hat Linux 4
Can someone please help me in resolving this issue?

  • How to reclaim "free space" on TM drive?

    I had 2 partitions on my external drive. I've deleted one of them as it is no longer need. Is there a way I can tell my TM partition to reclaim this new "free space" without having to erase the entire disk?
    Thanks

    That's exactly what I did to erase the partition, however, that partition is/was positioned first on the drive, above the TM partition. Hopefully that makes sense, but that's where I'm stuck at.
    Thanks
    in that case you can not absorb it into the other partition without reformatting the whole drive (that will wipe all the data off it). At least you can not do it with disk utility. Using disk utility you can only adjust the size of a partition by dragging its lower right end up or down.

  • Reclaim free space in datafiles

    Hello:
    I have taken over management of one of our test servers with Oracle 9i on Windows2000 and have noticed that there are two files that are much larger than the space that is actually being used:
    D:\ORACLE\ORADATA\ORCL\SYSTEM01.DBF - 17964M - (Used 1,542M)
    D:\ORACLE\ORADATA\ORCL\DATA01.DBF - 12511M - (Used 243M)
    How can I reclaim all of this unused space?

    Remember it is always best to reclaim space by moving all the objects to another tablespace and reclaiming all space. This will free up space within the tables and indexes as well.
    I use the following script to generate the commands for me:
    resizea.sql:
    drop table alan99;
    set pages 50
    create table alan99 as
    select max(block_id+blocks) block_id,file_id from dba_extents
    group by file_id;
    column tablespace_name format a15
    column pct format 999.99
    set wrap off
    set lines 120
    set trunc off
    column file_id format 999
    spool resizea.lst
    select b.bytes/1024/1024-a.bytes/1024/1024 CURRENT_meg,
    a.file_id,a.tablespace_Name,'alter database datafile '''||b.file_name||''' resize '
    ||trunc(c.block_id*8192/1024/1024+1)||'m;'
    from dba_free_space a,dba_data_files b, alan99 c
    where a.file_id=b.file_id
    and a.block_id=c.block_id and a.file_id=c.file_id
    order by current_meg;
    set termout off
    drop table alan99;
    set termout on
    spool off
    select 'Your output has been saved as resizea.lst' from dual;
    A script that will tell you what is inside is:

  • Table Partitions and Rolling Window: free space not reclaimed

    I have a couple of processes that involve the rolling window scenario where we drop an old partition and add a new partition monthly. We are seeing, however, that free space is not being reclaimed, and so I keep having to feed new datafiles into the tablespace (which is LMT). I was (mistakenly, it seems) under the impression that dropping a partition frees up that space for re-use.
    We're currently on Oracle 10gR2 (10.2.0.2), but these tablespaces were orginally created in 9i. I've read that one solution is to implement "table shrinking," however I also see that is only available on tables in an ASSM tablespace. I see that ASSM is the default for tablespaces in 10gR2, but since my tablespaces were created in 9i, I assume they are not ASSM.
    I'd like to see what other people think of this scenario. Surely a lot of people do the rolling window scenario and need space reclaimed.

    No, it is of concern because Sanadra was messing with the partitions. She could have inadvertantly caused something to happen, in this case the free-space issue, and it's imperative to get all of the details.

  • Unable to restore backup after updating iphone 4, because "not enough free space"

    I updated my iphone 4 to v7 via itunes (v12), and in doing so, my camera roll was erased as were most of my calendar events.  I am trying to restore the backup that I created just before updating, but I get an error message in itunes that says "itunes could not restore the iphone" because "not enough free space".  There is 2.5gb free on my iphone, and I created the backup just before updating so there should be plenty of room.  Does anyone know how to get the iphone to restore and/or how to put my pics & calendar back?  itunes hangs up at the end while syncing too...

  • Setup was unable to use existing system partition because it does now contain the requiered free space.

    I try to install it, but i select my free (fresh formated) partition with 35GB free space and i see:
    Setup was unable to use existing system partition because it does now contain the required free space.
    if i select partition with partition that does not contain the required i see
    "Windows cannot be installed to Disk 0 Partition 1. (show details)"
    so what is it? what can i test?
    My Disk has 250GB, my partitions:
    C: 8MB - Boot (7MB Free) - FAT
    D: 37,5GB - WINXP (27,9GB Free space) - NTFS
    E: 35,3GB - New (35,2GB Free) - NTFS - i want to install on it
    F: 160GB - Data (6GB Free)  - ntfs

    Is this 8MB "Boot" partition (formatted as FAT???) something you created when you partitioned this disk for the Windows XP installation, or is this an 8MB OEM partition that you've somehow assigned drive letter C: to?
    I wouldn't be surprised at all that your error message is being generated because thsi "BOOT" partition, labelled as drive C:, is only 8MB in size, and you can be absolutely positive that an 8MB partition is going to generate this error: "Setup was unable to use existing system partition because it does not contain the required free space."
    The correct answer really depends on whether that drive C: is the boot (sic) (the proper terminology is to call it the system partition) partition for the Windows XP installation. If it is, then you're going to have some repair work to do on your Windows XP installation first, so that you can free up that 8MB partition.
    In any event, I'm fairly certain that the solution is going to require the removal of that 8MB partition, as you've suggested in your most recent post.

  • After i empty trash (the secure empty doesn't work either), the system does not reclaim the free space.

    After i empty trash (the secure empty doesn't work either), the system does not reclaim the free space.
    I need to run the erase free space option from the disk utility every time...which is really annoying and time consuming.
    Any ideas how to solve this?
    Thanks in advance =)

    There is a thing in iPhoto whereby the first time you delete a photo it asks if you want to delete or just remove from the album, something like that.  Unfortunately it is one of these things with a "don't ask me again" checkbox.  Now, "deleting" photos only removes them from the album they are in.  To actually trash them I must then go to "all photos" and find them, to send them to the trash.   To help find them, what I do is rename them zzz or something, so sorting them will get them to the bottom of my collection.  Just maybe your photos are still lurking around?

  • Unable to create partition from free space on hard drive

    I have a segment of free space on my Macbook Air's hard drive. It was formerly a Bootcamp partition.
    When I try to create a new partition from this free space in Disk Utility, it prompts me to start creating the partition, but nothing happens after that. I can leave the machine alone for hours, and nothing has occurred. Disk Utility thinks it's working though, since it prompts me to cancel the process when exiting the app.
    Any thoughts on how to fix this? Thanks!

      4. Also see Freeing space on your Mac OS X startup disk.
      5. See Where did my Disk Space go?.
      6. See The Storage Display.
    You must Empty the Trash in order to recover the space they occupied on the hard drive.
    You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.

  • Unable to install when 32GB free space available

    LabVIEW 5.1 installer gave an error stating that my application could not be installed because there wasn't enough free disk space. The app requires ~50MB, there was > 32GB of free space on the C: drive.

    You may also suggest using a 3rd party partitioner like Partition Magic, so it's a dynamic partition done through the OS, vs fdisk-ing it.
    I'm not sure if this is a viable alternative, but you may want to see if just the LV 5.1 runtime engine installs w/o error, then build the vi's as an executable.
    I'd try the standalone RT Engine, vs. doing it off the CD:
