Can I use Datapump for replication of Delta from one database to another

Good Morning Experts,
I would like to know if can we use Data Pump (expdp and impdp) for replication between two database only for delta and not for complete database on daily basis and how?
Regards,
MS

MS,
I assume you are talking about both metadata and data. I don't know of a way to do this. I have heard of dba's using Data Pump import to track differences in metadata, but not to replicate them.
To track differences in metadata you do the following every day:
export full=y ...
import full=y sqlfile=full_todays_data.sql ...
Then from day to day, just diff the .sql file to see what changed. You will see if tables added/dropped columns, new indexes, etc. Based on this, you may be able to come up with a set of expdp/impdp jobs to replicate the modified objects, but there is nothing built in.
Hope this helps
Dean

  • Can I use flash drives to transfer data from one MBP to another at a differ

    I've looked and cannot find any info on the use of flash drives. Can I use a flash drive to transfer data from one MBP to another one at a different location? (ie; school Apple and home MBP) Grade tests and papers at home, enter data into home computer, then put it on flash drive and carry flash drive to school, transferring data to school desk top? Are certain flash drives preferrable over others, name brands, size, etc?

    Yep, you sure can. Just about any drive will work as mentioned above. But I'm partial to SanDisk and PNY. I've used both and they work great! Currently I carry both a 2GB SanDisk Micro Cruzer and a retractable 2GB SanDisk Cruzer, both really nice. Replaced my oldie but goodie 256MB PNY drive that I've been using since they first came out.

  • Can I use Migration Assistant to Copy files from one mac to another, but not delete the original files off of the original Mac?

    I just purchased a new Macbook Pro Retina, and I have an old Macbook Pro w/o Retina and wish to use migration assistant. I still want to use the older Macbook Pro and keep all the files on it, but copy them and also put them on my new Macbook. What I'm trying to say is, can I use migration assistant to move files to a new Mac, while keeping the files on the old computer?

    You can omit some broad categories, but you can't pick and choose individual items.
    See Using Setup Assistant on Mountain Lion or Lion (preferred method), or the similar Using Migration Assistant on Mountain Lion or Lion for the gory details.

  • HT1178 How can I use Time Capsule to move music from one computer to another?

    I want to move all the music I have on my old laptop (macbook) to my new macbook pro. How can I do this? Easy, simple, steps would be greatly appreciated!

    Are you moving the itunes library?? That is entirely different to moving just music.
    Apple have specific instructions for moving libraries..
    And there is no need to use the TC.. other than as a switch and router.. share the folder in one Mac to copy to.

  • Can I use my iPod to copy files from one PC to another?

    I recently bought a Mac Powerbook and an iPod, and want to move all my personal stuff off my work laptop (an IBM ThinkPad) onto the Powerbook. Most of my files are photos, Word documents, excel files; only a few are music files.
    When I bought the Powerbook, the guy in the Apple shop said I could use my iPod like a hard disk to copy all the stuff over - using a flash drive would take forever!
    Was he right? If so, how do I do this? I can't seem to get past the fact that my iPod is now Mac formatted, which my IBM Thinkpad doesn't seem to like!

  • HT1554 can i use migration assistant to copy applications from one mac to another???

    hey, i have an iMac G5 (ALS) and an a G4 iMac from 2002, the G5 is running OS X 10.5.8 and the G4 is running OS X 10.4.11. I want to copy apps from the G4 to the G5 without loosing them in the G4, is that possible???

    What applications? Why can't you just reinstall them? Copying a file does not delete the file in the process, so the answer to your specific question is, yes it is possible.

  • I can't import a table contains BLOB column  from one user to another user.

    1) I create two user both have connect role,and each has its own tablespace, DDL:
    create user d2zd identified by d2zd default tablespace d2zd quota unlimited on d2zd account unlock;
    grant connect to d2zd;
    create user d3zd identified by d3zd default tablespace d3zd quota unlimited on d3zd account unlock;
    grant connect to d3zd;
    2)Then enter oracle as d2zd and create a table contains BLOB column and insert data to the table.
    3) export d2zd as follow:
    exp d2zd/d2zd file=d2zd.dmp
    4) import to d3zd as follow:
    imp d3zd/d3zd fromuser=d2zd touser=d3zd file=d2zd.dmp
    the question is the table with BOLB colum can't be import,
    it says:have no privilege on tablespace d2zd.
    How can I import a table contains BLOB column from one user to another user?

    Hi - the reason for as our friend already told ist that a blob can be stored outside of the table segment, in another Tablespace, This is for performance reason.
    Sou you would need to have Quota on two tablespaces.
    the one which holds the table segment the other which holds the blob(segment).

    Kindly let me know if there is any oracle documentation for this .It's not an Oracle created package, it was created by Chris. It's based around the UTL_TCP package if you really want to get into the nitty gritty of how it works, but I don't think you do.

    Copy the iTunes folder (Mac: Home\Music or PC: My Music) to the same location on the new computer. If an iTunes folder already exists on the new computer (it will on a Mac) replace it with one you copied.

  • Best Practice for Migration of BO  from one server to another

    You need to copy your input and output file stores from the old server to the new server. By default these are located in the <Business Objects install path>\FileStore directory.
    Then you need to stop the CMS, Right click the CMS,Click the Configuration tab, and then click Specify.
    Choose Copy, then click OK.
    Choose the version information for the source CMS database.
    Select the database type for the source CMS database, and then specify
    its database information (including host name, user name, and password).
    Select the database type for the destination CMS database, and then
    specify its database information (including host name, user name, and
    password).
    When the CMS database has finished copying, click OK.
    Once this process has been completed start the CMS and click on update objects -> located on the top of the CCM.
    I'd advise taking full backups beforehand.

  • How can I transfer entire contents of Mail mailbox from one Mac to another?

    I've long wondered how to do this:
    I have two Macs - an iMac and a MacBook Pro.
    I have categorized several hundred emails on the MacBook into a separate "mailbox" by itself. Let's just call it "Project XYZ emails" for the sake of discussion.
    I need to transfer ALL of those emails +en masse+, hopefully still categorized together into a separate "Project XYZ emails" mailbox file, from the MacBook to the iMac. How is this done?
    In the old days, when I used to use Eudora, this was quite simple -- one could physically locate the separate desired "mailbox" file in the Finder and just copy it from one hard drive to the other, and then place the mailbox into the appropriate place of Eudora's file structure on the second computer. Relaunch Eudora and voila, the new mailbox is there for viewing, etc.
    But in Mail, I can't find any tangible "file" on my hard drive that represents a "mailbox" in the Mail program. And that includes control-clicking the application file itself and choosing "Show Package Contents." When I do that, I can see, after burrowing into the folders, a single large file called "Mail" which I think contains ALL mailboxes lumped together. But I can't see a way to separate them for individual manipulation.
    Any suggestions or ideas on how to copy entire mailboxes in Mail from one Mac to another?

    Thanks! Seems to have worked.
    Once I imported tham, I had to fiddle around renaming mailboxes and "moving" the emails to the desired locations, but that only took a minute. So overall, seems like that's the solution! I only wish that the steps to do this were made clearer by Apple in the Mail "help" menu -- where I couldn't find any mention of how to do this.
    A happy ending, in any event.
    In case anyone reads this in the future, let me add in the missing steps, to make it perfectly clear:
    In Mail, choose 'archive mailbox' from the mailbox menu.
    +Copy the newly created archived mailbox file, which will probably be a file with the suffix ".mbox," from the original machine to the second machine.+
    On the second machine: In Mail choose 'import mailbox' from the file menu.
    +The emails will now appear in a new mailbox in Mail listed under the name "imported" or "import." If desired, either rename the mailbox, or create a new mailbox with the correct name, and "move" all the emails into it.+
    Done!

  • How can I move my iPad's iTunes backup from one user to another?

    Is it possible to move my iPad's iTunes backup from one user to another, so as to change which user the iPad is syncing to without deleting any app data? Currently the iPad is synced to one user on my iMac, and I would like to transfer it so that it will sync with a different user on the same iMac (using iTunes, of course). I'd like to replace content from the old user's iTunes library with my user (eg. music, movies), but I don't want to loose app data in the process if I can avoid it.
    I have tried to use the pathway /Library/Application Support/MobileSync/Backup but my iMac doesn't seem to have a MoblieSync folder. I wouldn't know what to do with the backup anyway though.
    Can anyone help me or is this request too complicated, difficult, or impossible? Thanks for your help!

    The Apple Document covers this. See the footnotes of my google docs
    I've done this, it is easy, but takes time and patience.
    On the existing mac with OSX and Configurator:
    ========================================
    - run disk utility and verify your disks are ok, a must
    - make note of the user logged in when using configurator  such as "bob"
    - connect a new or newly reformatted USB formatted for Apple
    - run time machine and backup to the USB
    - Take the mac off the network,
    - Buy a new mac
    - setup the mac with a new logon account like Paul or  "bob2"   do not use BOB !!
    - finish the new purchase setup, get to your desktop
    - now run the migraiton assistant  moving bob from the USB to the new mac
    - reboot, logon as bob, launch configurator and connect just one ipad.  Test

    To move cursor from one textbox to another text box ,I have taken the length of the textboxes of the first column.I used onkeyDown event .
    in the function ,first i checked the condition like
    for(i=0;i<form1.box.length;i++) //box is the name of the textboxes
    if(event.keyCode==13)
    form1.box[i+1].focus();
    return false;
    by using this the cursor is moving from first text box to second textbox and stops.
    if i use event.returnValue=false; instead of return false ,then the cursor automatically going to the laxt textbox of the column.
