11gR2 database portability from home and school

I have a grad research project to refine a star datawarehouse started by another grad student working on this both at home and at the school. I will have a backup copy of the the test version which I can carry on a protable usb HD back and forth between school and home. I have to convert the existing 10gR1 datawarehouise to an 11gR2 dw, both versions using windows xp.
Ques 1:Can I do this conversion by moving talespaces or only by using a dmp file created by datapump export from 10gR1?
Ques 2: Is there a way to configure the database software so I can locate all the instance files (the dbf, control, spfile and undo - some or all) on the portable hd, and activate them from either an installation of 11gR2 software located at either home or office depending on where I am at the time?
Ques3: does it matter if one of the 11gR2 installs is on windows xpsp2 and the other on windows xp sp3?
I have the alternative of leaving the portable hd permanently attched to the pc at school and the pc is located in a physically secure location. From home I can RD to the pc as it has a static IP. I have 5 years exp as an Oracle DBA and have worked on oracle versions 7.3.4 thru 10.2, but never with 11g and never with a dw.

Hi,
In your case there is no big difference 10g / 11g.
Ques 1:Can I do this conversion by moving talespaces or only by using a dmp file created by datapump export from 10gR1?

You can choose your upgrade method. The simplest is maybe expd/impdp.
Ques 2: Is there a way to configure the database software so I can locate all the instance files (the dbf, control, spfile and undo - some or all) on the portable hd, and activate them from either an installation of 11gR2 software located at either home or office depending on where I am at the time?
Never tested that but it seems feasible if you have controlfiles/redo/datafiles on the portable disk. No need to have the spfile on the disk, just duplicate it in the 2 homes.
What is your backup method ?
Ques3: does it matter if one of the 11gR2 installs is on windows xpsp2 and the other on windows xp sp3?
Test it but it's always better to have the OS in the same version. You cannot install SP3 on the system still having SP2 ?
Best regards

  • HT4623 Cannot update from iOS 6.1.3 to iOS 7...says that I cannot verify because I am not connected to the internet when I am clearly connected to the internet. I've tried from home and school.  Now what?

    I am trying to update an iPad 2 to iOS 7.  It hasn't updated since iOS 6.1.3.  When I try to update it, I get a msg box that tells me I cannot verify because I am not connected to the internet.  This is not true because I AM connected to the internet here at school.  I've tried at home and it does the same thing.  What to do now? 

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

    This will avoid me lugging around my mac, sorry for my english.

    Yes, this has been allowed with Adobe applications going back many years.  A program such as Photoshop can legally be installed and activated on two computers at a time for the use of the single licensed user.  You can't install legally on your own and a friend's computer for use by the two different people.  Prior to Creative Cloud, there was an unwritten limit on how many times a given application could be activated, but there is no longer such a limit under CC.  That means you could theoretically install on three or four computers, activating only two at a time, and then deactivating one or both before activating on another computer.

  • I work from home and they were checking my certificates and said that there is fiddleroot on my computer and I need it fixed. How do I do this?

    I work from home and my headset is always cutting in and out and I am also being disconnected during work hours. This is a huge issue and talking to my tech support team they said that there is something called fiddleroot on my computer which makes certificates for every site I go to, which in turn makes my certificates I need for work not work. I need help removing this from my computer. Please help.

    hello Tiffany2181982, unfortunately the fiddler2.com issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.

    afterwards, run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

  • Administer from home and work?

    I am the administer of CPS. I work from home and at the
    office. My name appears twice as administrator. The drafts sent for
    review show on one or the other draft consoles, but not both. Is it
    possible to administer from multiple computers using just one
    Administrator name? Thanks, Jean

    That's a horrible work around and doesn't do what I'd like at all.
    I have an iPhone, I have a home computer that I put stuff and sync it to.
    I also have a job at a company that produces a TV show and commercials. I'd like to be able to drag and drop copies of those onto my iPhone so I can show people. It doesn't make any sense, nor is it any "fun" to have to drag those to a USB drive, take them home and THEN load them on the iPhone.

  • Somehow, I created 2 Appe ID's...1 from home and 1 from work.  I purchased additional space on iCloud with one ID, but I need to transfer it to the other.

    Somehow, I created 2 Appe ID's...1 from home and 1 from work.  I purchased additional space on iCloud with one ID, but I need to transfer it to the other.

    Having read some other posts I think I have answered my question. If I was somehow able to terminate my old (unwanted) account and Apple ID I would no longer be able to access the material I bought with that ID-  so I'm stuck. I have to learn how to manage that situation.
    This is unfortunate for Apple consumers. Life is complicated for families these days and this "rule" although it is in place to prevent cheating and fraud makes things unnnecessarily difficult for me and my family as in my niaevity (sic) with the online world I bumbled into this situation. Not everyone is out to rip off Apple - one of the worlds richest corporations- or the entertainers who market their work through iTunes.I would just like to be able to enjoy the entertainment I pay for where and when I like to on whichever computer is available to me. And I'm not terribly computer literate.   
    It would have been nice to have had the opportunity to speak just once to a real person in the employ of Apple to explain my situation to them.

  • Can documents saved on my time capsule be accessed if not connected i.e. I am away from home and want to access documents saved on my time capsule

    Can documents saved on my time capsule be accessed if not connected i.e. I am away from home and want to access documents saved on my time capsule

    Yes, if you setup one of the methods.. see
    https://discussions.apple.com/docs/DOC-3413
    You must use a Mac for any of those.. if you want to use some other OS tell us.

  • Transferring back-and-forth from home and work

    I need to transfer my Mail and Address book back-and-forth from home to work.
    1. Which files do I export from home?
    2. Where is it imported into work?
    3. Are there any known issues with the database files becoming corrupt from going back-and-forth like this?
    Thanks.

    what os are both macs running on?
    i would suggest you look at www.mac.com, the .mac service, if you want to sync various data between two macs - works with tiger and leopard os, but not panther.
    manually moving folders may be cumbersome and end up with unintended consequences, as in human error or other glitches.
    nonethless the folders that contain data for both mail and ab are respectively homefolder/library/mail and homefolder/library/mail downloads for mail and homefolder/library/application support/address book for ab.
    you will also have to copy the com.apple.mail.plist and com.apple.mail.searchhistory.plist - for mail - and the com.apple.addressbook.abd.plist and the com.apple.addressbook.plist files - for ab - all four located in homefolder/library/preferences.
    hope this helps

  • Can I use iTunes Match while I'm away from Home, and my family still use Home Sharing via Apple TV?

    I would like to be able to use my iTunes Match account as I am frequently away from home.
    However, my family would also like to be able to use Home Sharing to listen to music, watch movies stored on the family iMac, using the Apple TV.
    At the moment, iTunes Match & Apple Store uses a different Apple ID to Home Sharing.  I don't want the kids to be able to download movies etc on the Apple TV.
    Is there a way that I can achieve both at the same time?

    Yes, iTunes Match alleviates this situation.  As long as iTunes on both of your computers is using the same Apple ID, you can add songs to either one, and once they have uploaded to iCloud, they will be available on any of your iDevices AND in iTunes on the other computer.

  • ICal Alarm emails coming from home AND work email?

    My iCal calendars are synced using MobileMe with my home computer and my work computer (and my iPhone). I'll sent an alarm on my work calendar to email me at work. I am now getting two emails sent TO my work email From my work email AND my home email. Is there any way to stop my home sending out work alarms?

    Hi BenChase,
    Select the calendar you don't want to send alarms in iCal's calendar list. Press Cmd-I to open its Info panel. Check the box that says 'Ignore alarms'.

  • I work from home and connect to my work via VPN.

    Recently, I was being locked out several times a day.  It was discoved that my Mac-Mini is trying to connect to my work network, but I have never set anything up for this to happen.  How can I stop this?  I set up on my Mac Mini a app called PocketCloud installed, but have deleted it, to connect remotely from my iPad or iPhone, but that is usually not running. 
    I now have to power down my Mac daily while working to avoid the intermittent lock out. 
    I have no other apps running that I can find. 
    My mini is connecting to my internet wirelessly.  There is no network wiring.
    I do see my work computer listed in the in the side bar under shared, but I cannot find a way to remove it.  When I click on it, it attempts to connect and fails.  I then get an error.  "There was aproblem connection to the server "P44XX02".  The server may not exist of it is unavailable at this time.  Check the server name or IP address, check your network connection, and then try again."
    Does anyone have any suggestions?

    Found the reason.  Although I had deleted my work email account from exchange, hidden was the Addressbook entry that was trying to connect consistently.  I deleted this from the setup and no more hidden attempts were made to connect.

  • Work from home and just moved house, really slow i...

    Hello, I have just moved house ( 2 weeks ago) I use to get BT infinity so I was expecting a big drop but nothing like this. When I orderd my new BT package I was told to estimate speed of 12mb.
    My internet cuts out regularly - 5 to 10 times aday and most of the time when I get incoming and out going calls.
    -I was getting 11.1mb the first two days I moved in.
     - Currently plugged into test socket and did the 17070 and 2 and getting some static sound but did this with a wireless phone standing next to the receiver.
    -Just got brand new ADSL filters from BT.
    Any help would be fantastic due to this is damaging my work with clients - Thank you!

    Already talked to BT about BT business two years ago and was told I did not need to "upgrade"
    I have contacted a BT enginer who is coming out next week.
