Where can I find good general information about data migration?

I need to move about 120GB of data from my Oracle8i Enterprise Edition Release 8.1.7.4.0 - 64bit server to a new Microsoft SQL server 2005 64 bit.
What is the best way to get this data across ?
Thank you.

Seriously though, as well as the link from the other poster about
datatypes not being compatible, you should also worry about
SQL not being the same - look at
http://social.msdn.microsoft.com/Forums/en-US/transactsql/thread/804dc08e-927a-4152-af06-a90c0ee63230/
You should also worry about CONSTRAINTS, PL/SQL, Sequences,
the list is endless.
An Oracle (and SQL Server) database is not just a collection of bits,
but a system - if it wasn't, we'd all store our data in Notepad for free!
Brooks (mythical man-month) says "be prepared to throw one away"!
Another question you should ask yourself is
"What is my own area of expertise?"
Are you a Perl/Python/Java/Delphi/C/C++/<insert_language_of_choice> programmer?
Look at doing the work in stages using staging tables.
Best of luck.
Paul...
Thank you.--
When asking database related questions, please give other posters
some clues, like OS (with version), version of Oracle being used and DDL.
Other trivia such as CPU + Disk configuration might also be useful.
The exact text and/or number of error messages is useful (!= "it didn't work!"). Thanks.
Furthermore, as a courtesy to those who spend time analysing and attempting to help,
please do not top post and do try to trim your replies!

  • Where can I find a general information about settings of the PCI-IMAQ-1411 board?

    There is many attributes in the properties dialog of the IMAQ channel in the M&A Explorer. For example Mode (Frame/Field), Lock speed (Slow/Normal/Fast/Very Fast), Luma Comb (Disabled/Enabled). Where can I find a comprehensible description of them?

    The starting point is the help file. There is a section with the title: "Setting IMAQ Device and Camera Properties". That section provide some explanations about the properties and options to configure your IMAQ cameras.
    You can obtain more information by visiting the Developer Zone at the NI website. Look for the Vision section at the Resource Library. The exact address is:
    http://zone.ni.com/devzone/devzone.nsf/webproducts/7d6146d8c67a832e862567f1006c29ee?opendocument
    You will find explanations, tutorials and examples about different topics in vision, including configuration descriptions.
    Finally, a full understanding of some properties requires knowledge about vision and image processing. A good book about Image Processing in general should be of benefit.

  • Where can I find the detail document about certain method of a class?????

    Moved to correct forum by moderator
    Hi everyone,
    where can I find the detail document about certain method of a class?????
    e.g.  the class CL_GUI_ALV_GRID , when I was going through the class and looking
    at the methods, sometimes the method description is just like the method name,
    and I cannot know what the method does. 
      so, I am wondering  where I can find the detail information about the class???
    Edited by: Matt on Dec 4, 2008 11:55 AM

    Hi,
    Most of the times the SAP itself provides the documentaion of the CLASS. when you click on the METHOD name the METHOD DOCUMENTATION button you can see on the application tool bar.
    more over the names of the methods suggest what it is going to do.
    SET_ATTRIBUTE( sets the attribute)
    GET_ATTRIBUTE( gets the attribute value that is provided to the method)
    GET_CHILDNODE
    BIND_TABLE
    etc
    like this
    regards

  • Where can I find good organ and keyboard sounds for Logic Express?

    Where can I find good organ and keyboard sounds for Logic Express? The included sounds seem to be lacking or hard to access.

    Update: Not terribly impressed with the interface for NI's Vintage Organs from the demo download, although the sound demos sure sound good. The letters are tiny and hard to read and the whole thing feels very PC-centric. I guess a guy gets spoiled by the intuitive stuff. I think what I'll try for now is just hooking up my keyboard (Korg N1, circa 1998, about 1700 built in sounds) as a sound module and record the waveforms when I find a sound I like. I did find the EXS24 and several other software synths with some cool organ sounds after digging a little deeper. It would be good if Apple came out with another jam pack just for organs and keys, as the existing jam packs are so easy to use.

  • I updated SCCM 2012 R2 from CU3 to CU4. Where can I find good directions on what else I need to do to make this work?

    I updated SCCM 2012 R2 from CU3 to CU4. Where can I find good directions on what else I need to do to make this work? I'm assuming I have to deploy the new clients?
    Thanks,

    You have to create different collections (x64 vs x86 clients) because the .msp to be deployed is architecture specific.
    "Distribute content" just distributes binaries to distribution points. You can select a collection there, but that has nothing to do with clients. It just distributes content to DPs that are assigned to collections.
    Torsten Meringer | http://www.mssccmfaq.de
    Ok. That is helpful. I appreciate the response. I hate to ask another question, but I', still learning the product. In the Step-by-Step SCCM 2012 R2 CU4 Installation Guide from System Center Dudes, it says to create the collections by using their predefined
    queries. I tried to enter these as queries but I think I am doing so in the wrong area of the collection creation process. Could you break it down for me?
    Do you know of any good training (free) that is video based an breaks SCCM 2012 R2 down into smaller more detailed steps?

  • Where can I find the current time and date of Time Capsule?

    I have a home network consisint of 2 x Time Capsules and 1 x Airport Express.  All is working fine.  I would like to set up access control for one machine connecting to the network and I can see I can do this under Access Control on the Airport Utility.  My question is where can I find the current time and date setting for these devices? 
    I can set them to use the time.apple.com server to set the time automatically, but I can't find where to see the current time and date of the device.  The only place I can see reference to the time and date is on the logs and statistics under the Advanced tab of the AirPort Untility.

    I don't think you can change the time and date on the TC itself, it just connects to a time server (and you set your own time zone).

  • Set Up Security: Where can I find good documentation

    Setting up spesific security for user groups is causing be a great deal of trouble. I want to grant "add and modify" rights for users and full rigts for administrators. However, whatever way I do it, the result is wrong. Where can I find some good documentaion with examples? I'm using IFS 9.0.2.

    I've also having some troubles with this. Though I believe I now have a decent understanding of the security model of IFS I can't get it to work.
    I have some users which need all access to a folder + its subfolders. And no matter what I can't get it to work.
    As always with Oracle there are no examples - only tons of manuals.
    If anyone can tell me how to do this => [email protected] - so far I've spent DAYS reading & trying out different combinations!
    YES - I could (and DID) read the Administration & Setup Guide. But it didn't help one bit (we're now three persons who have looked at this and still no progress).
    So Oracle... MORE examples please. Or rewrite the manuals so you don't need to be an expert in ACLs before understanding how to use them to do -simple- tasks.

    One source is in the LabVIEW bookshelf installed with LabVIEW. Search for the document Performance and Memory Management. Another source would be the tutorials on this web site.

  • Where can I find good instructions about camera and how to take pictures?

    I don't know why I am having so much trouble taking pictures.  I can get it on the right camera...front or back....imcan take a picture of what imsee, delete it, send tomfacebook, etc.  What I CANNOT do is focus on an object to photograph. I tap on what I want and get a little blue square.  Thatmismwheremi am stuck.  Imhavemthaaped, pinched, etc but I,m not getting it.  I have an iPad book but it gives no details about the part I am stuck on.  I know it  is something obvious but I am not seeing it.

    I think the iPad goes to,sleep which is why it turns black...I will change the settings so it stays awake longer!
    I am using iOS5 which explains no slider.  I guess I don't know,hot to pinch because when I think I am doing it nothing happens. Mint pinch what you do on any sceen to make the font bigger....zoom?  I have no trouble with that anyplace else, but it is not happening here,m I tap and get the blue box on the object I am focusing on. Pinching before or after changes nothing that I can tell. 
    I am on the back camera....or at least I think so.  Thanks for all your help....there is something I am not doing and itmismdriving me crazy.  I think it's the pinching that is the problem, but I don't know what to do to,change it.
    Also is there any way a person can stay logged into this discussion for more than 30 seconds?  When I go back to try something you suggest, i am logged out almost instantly.

  • Where can I find the "event" information I had in iPhoto events in new photos app?

    Just upgraded to OS X and the new Photos app and I am having a hard time adjusting from iPhoto where I had (happily) organized years of photos into events. I can see my 771 "events" now called albums in a sub-album called "iPhoto events" HOWEVER, I cannot seem to find/view the little notes or summaries of event information that I had inputted in iPhoto.  I often wrote a brief (or detailed) bit of information, anecdotes or fond memories about various "events" and now I am frustrated that might all be gone. Can anyone help?

    Oops Sorry Jumped the gun again! i found out how to do it. I was using my jot touch styles which mean you have to hold down the icon on the upper left with the styles then use your fingers to do the pinch and zoom gesture to make it work

  • Where can I find Firefox update information on the website?

    Firefox was recently downloaded on the laptop I am using with Win7. Over the past few weeks, several times I've been surprised to find a tab open from Firefox telling me to click here to update. I've been told to always get updates from the website, not from these pop-ups. But I don't know where to look on the site to get the updates. I see in some of the questions that people want help with that there is an auto update feature and also manual--but I don't know where to find them. I am not very intuitive in poking around--so finally am writing for help, if you can direct me where to go to see if there really are updates I need to do, or if the messages that I am getting are bogus.
    Please direct me to the correct page to check for updates which I assume is on the site, but I am not finding.

    Its so easy ,and you can find it very well. Follow these steps :
    Goto :-
    * '''open menu''' > '''Open help Menu''' > '''About Firefox''' .
    Note: if your browser settings is checked on '''Automatically Install Updates(recommended)''' then you no need to update from anywhere.
    you just follow the above step and it automatically start updating your firefox.
    to check the settings you have to go on : '''open menu''' >'''Options '''> '''Advance''' > under '''Update''' tab > click on '''Automatically install updates'''
