Moving Tablespaces and other data-Objects to another HD

Hi,
XE is running on Win XP Pro SP2 here. It installs the datafiles on C:\ too. That's no proper solution because system loss could cause data loss in a bad crash.
Otherwise in managed enviroments often the sytemdrive will be autmatically cleaned for new desktop solutions.
Is there some experience about moving the tablespaces /moving the datafiles to another HD/Partition?
Doing this on 10g with EMGC is an easy job.
But how does this work on XE?
thx for respone
regards
Franz

You can not move tablespaces. They are logical units that do not have a location. The required space allocation for a tabelespace is through one or more datafiles.
There is no problem moving data files to another drive. Effectively you
1) shutdown the database
2) copy the data file to the new location
3) Update (not edit) the control files to point to the new data file.
Step 3 is done by bringing up the database into 'control files are available and read into memory, but data files are not available' (the 'Mount' state) and issuing the ALTER DATABASE RENAME FILE ... command.

  • I have followed "Importing favorites and other data from Internet Explorer" but although I've worked through the dtages and it says it has worked, the expected internet explorer folder does not appear in bookmarks

    I have installed Firefox today, and like the look of and the speed. But I have an extensive set of foldersin my IE Favorites and remebered passwords I don't want to have to reimput.
    I have now tried twice folowing "Importing favorites and other data from Internet Explorer " which seemed to go smoothly, once with IE open and the other with it closed, and closed down my PC between each attempted installation. Any ideas?

    It usually works better if you export the Favorites in IE to an HTML file and import that file in the Firefox Bookmarks Manager.
    * Export the favorites in IE to an HTML file (bookmarks.html): File > Import and Export
    * Import the HTML file in Firefox: Bookmarks > Organize Bookmarks > Import & Backup > Import HTML: From File

    If I already have, as I mentioned, my iTunes music and Time Machine data on this ext. FW drive, can I place the data in each new partition?
    that's right, the data should be preserved. it will remain on one partition and a new empty partition will be created below it. you can move your Music library to the new partition. DO NOT move your TM backups. they can not be moved using Finder.

  • I have 646 websites that have stored cookies and other data on my computer. How necessary is it to keep these stored files?  My thought is to delete them.  Input?

    Good Morning,
    I have 646 websites that have stored "cookies and other data" on my comupter.  How necessary is it to keep these??  My thought is to delete them.  Any advice?

    I have never encountered a site to which I couldn't log in again after trashing its cookie(s). If you use Firefox (Preferences), you can list exceptions of cookies you don't want removed (e.g., for startpage and duckduck searching, I keep startpage and duckduck cookies in order to keep those search settings) and those you never want to accept (I have all Google cookies blocked. Doesn't keep me from using Google search, images or maps, but if you belong to a Google group or run some  kind of Google program, that may be a problem.) Safari probably has some cookie manager extension available for that also.
    If you use Firefox, NoScript will effectively block all google tracking that occurs on mousedown.
    In your browser>Preferences, make sure you don't allow third party sites to store cookies.
    What's even more worrisome than ordinary cookies, are Flash cookies ("Local Shared Objects"), which are persistent cookies, including the "evercookie." They aren't stored in the browser.
    With Firefox, you can deal with this by using the Better Privacy Add-on, or see this post of mine, as modified by Kurt Lang.

    Once you are in Recovery Mode, it's too late to do any backup. I am afraid you are going to lose your data.

    No. If you made your backup to iCloud, iTunes will not restore from an iCloud backup. See:

    Every time my macbook performs a system update (which all you mac users know is weekly or bi-weekly) all of my passwords are wiped, as well as any address, phone number, and other data for filling in fields.
    Is this supposed to happen? Is there a way to avoid it?
    I only just started using Firefox a month ago when the Flock programmers turned stooges, so if I can't avoid this it's not too late for me to switch to a different browser.

    You should get your data back when you leave Private Browsing mode, i.e. remove the checkmark and restart Firefox.
    Firefox stores the open tabs in the sessionstore.js file, so make sure that Session Restore is working properly.
    You can reset <b>browser.sessionstore.*</b> prefs that are user set (bold) to the default value via the right-click context menu on the <b>about:config</b> page to make sure that Session Restore is enabled and working properly.

  • HT201442 restoring and other data

    why can't I restore my iphone? My "other" data is taking up 5GB of my 6.34 capacity storage. Have erased all photos, videos, apps and music. when i try to restore I get a message that: could not restore, the device isn't eligible for the requested build. Anyone have any suggestions to: a) get the other data off my phone, b) restore phone?!!??!
    Any advice appreciated.

    Like every other operating system, iOS stores temporary files and app caches locally on the iPhone, iPad, and iPod touch, and these files can build up over time. Generally iOS is pretty good at housekeeping, but if you’ve had a device for a long time and haven’t deleted old unused apps, resynced recently, or restored from a backup, you may have more of these temporary files and caches stored on your iOS device than you think.
    You can use apps like iLike, Phoneclean to remover these junk files and "other" data:

    Buy one hard drive for TimeMachine, large as possible for maximum amount of saved states, keep it connected more often so it updates more often to recover deleted files.
    Buy one hard drive the same size or slightly larger to clone your boot drive to it, it will be a hold option key bootable clone in case your boot drive fails to boot. Update it before doing anything major to your machine. Keep it disconnected in case of malware so it doesn't get infected or delete your files.
    Buy one hard drive for extra storage if your boot drive is getting full for instance.
    Buy one hard drive to backup the extra storage drive and treat it like the clone, make sure you have clean extra storage drive before connecting and updating it.
    Label and date each drive, your memory will fail you and you'll accidentally overwrite a drive.
    Keep your drives separate and in their respective purposes, in other words do not use partitions or use TimeMachine to backup other drives.
    Never use Filevault, it's cracked, it's worthless, impossible to recover data and you'll have to give up the password for repair or customs/searches anyway. Use a external hardware based encrypted drives and USB Iron Keys. This way your sensitive data is off the machine and can be used with another machine.
    Despite how many drives and backups, it's good to also make burned and labeled DVD's of your most important files like music for instance when you first get them. It's because sectors fail on hard drives and takes out your data and thus on all backups made afterwards. With burned DVD's it's permanent, unless you scratch it, melt it or loose it.
    Hardware also fails, more often than software because it's moved/abused while in operation.
    If you lose your TM drive, you ALSO lose what's on the other partitions on the drive or data that TM drive was backing up from other drives.
    Drives are cheap, data is not. Protect the data. Because it's a fortune trying to recover lost data off a dead drive.

  • ITunes Fix for Manually Moving Music and other Media

    Intro
    Any iTunes 7.x user who manages their own music library outside of the "iTunes Music" folder might be able to tell you that iTunes DOES NOT respond well after manually moving tracks from one place to another on their computer systems. In fact, any file you move becomes immediately unplayable in iTunes. And, if you're anything like I am, losing several years worth of song rating metadata and playlists is not a good incentive for change. However, one thing others might not be able to tell you is that there's an easy workaround for the problem and you get to keep your playlists, ratings and other info. Read on to learn about the workaround.
    About the Workaround
    The workaround is a simple hack I devised after recently transferring a good portion of my music library between hard disks and running into problems with iTunes. The fix steps provided below are intended to circumvent the problems with iTunes and give users the freedom to move songs and other media files on their computers while maintaining the integrity of both the ratings and the playlists. Meaning you won't need to manually update the song locations in iTunes one-at-a-time, which, at version 7.02 is the only way to accomplish this task using the program.
    Please be aware that not all information is retained using this workaround. What will be lost are the following: the "Recently Added", "Recently Played" and "Top 25 Most Played" iTunes Smart Playlists; any media file play counts; last played information; and possibly some other data used only internally by iTunes.
    So, if you're comfortable parting with some metadata while keeping your cherished song ratings and playlists intact during file relocation, read on to learn how to use the workaround.
    Workaround Steps
    The following instructions walk step-by-step through the process of this workaround.
    Note: All backslashes used in file paths have been converted to forward slashes so that they will adhere with MySpace XSS security validation checks. These altered paths can still be copy/paste into Windows Vista's Explorer program once the Username is changed to the User Account where the iTunes files reside.
    Preparing for the Move
    Before you move your files, do the following:
    1. Close iTunes.
    2. Create a backup copy of the following files:
    iTunes Library XML (iTunes Music Library.xml)
    Note: Vista users can find the Library XML at C:/Users/Username/Music/iTunes
    iTunes Music Database (iTunes Library.itl)
    Note: Vista users can find the Music Database at C:/Users/Username/Music/iTunes
    Moving Your Files
    This part should be self explanatory, but while you do it make sure to note the following two things:
    1. The path where the files were previously stored (e.g. D:/Music).
    2. The path where the files will end up (e.g. E:/Music).
    Execute the Fix
    After your files are moved, complete the following steps to implement the fix.
    Note: Do not open iTunes during this process.
    Hack the iTunes Library XML
    Once the files are moved the Library XML file locations will be out of sync. Follow the steps below to update them so that they now reference the correct file locations.
    1. Open the iTunes Library XML with a Text Editor with a Find/Replace function.
    Note: Vista users can find the Library XML at C:/Users/Username/Music/iTunes
    Tip: Do not try to do this with Dreamweaver if your Library XML is greater than 10MB.
    2. Perform a Find/Replace using the following inputs:
    Find: Path from Step 1 of Moving Your Files
    Replace: Path from Step 2 of Moving Your Files
    3. Confirm your results, and then save and close the Library XML.
    Delete the iTunes Music Database
    Hacking the iTunes Library isn't enough to fool iTunes. Like the Library XML, the Music Database also holds the file locations of all of the media stored within the program. And it's smart enough to wipe out the Library XML hack if iTunes is opened before completing this step.
    Ensure you have backed up the iTunes Music Database (iTunes Library.itl) and delete the file.
    Note: Vista users can find the Music Database at C:/Users/Username/Music/iTunes
    Back in iTunes
    Once the fix is in place you can now open iTunes again. You will notice that all of your playlists, music and other items have vanished. In order to recover them all (with the exception of the Smart Playlists mentioned in the About the Workaround section above) we'll need to import the hacked Library XML file back into iTunes.
    1. Open iTunes and press CtrlShiftO or go to File > Import…
    2. Navigate to and Open your modified Library XML (as pictured below).
    3. iTunes will then begin importing the contents of the XML file (as pictured below).
    Note: This process may take a while, depending on the size if your library.
    Wrapping Up
    Once the import process is complete iTunes will look almost exactly the way you left it, with the exception that some playlists have been duplicated and the number of songs may be a hair off. To fix this problem delete any duplicate playlists in the "Library" panel in iTunes. You can now test out the changes by selecting an item moved earlier and testing it out. All that's left from there is to let iTunes perform any automated analysis it needs to do and rock on.
      Other OS  

    Holy Smokes:
    I appreciate your detailed workaround post. My question is this: I use iTunes to keep everything organized (though I'm well aware of the shortcomings...) and can use the simple solution that Chris from CA posted, but I don't have room to consolidate everything. My read on consolidating is that you copy from wherever you have your music located (and right now my music is outside of the MyMusic/iTunes folder, as that backs up to my work server) and so you have to have enough room for all of your music to be copied (and then you delete it from its prior location). That's how Apple describes it in, e.g., http://docs.info.apple.com/article.html?artnum=301748. I ain't go that kind of room. Is there any way to make the move to a completely different PC by following the simple option? From the posting I just linked it sounds like you MUST consolidate whether you use you iPod to move things or use an external drive.
    Of course, I can use your workaround, but I thought I'd ask first. Many thanks.
