Copying large production DB to another system

You are a copying a production database to a QA system. It’s very large and you decide to exclude all the table data for the some of the larger tables that are not required for the QA system. All table definitions need to be retained however. How would you do this?

Yes, export and import is a good way to go. What version are you running? A slightly different suggestion would be to export the entire schema or schemas with the ROWS=n option. Then export again with the tables you want the data for. export has a tables option where you can list the tables you want. And in newer versions there is an exclude option where you identify tables not to be exported.
Then, with the 2 exports you would apply the schema only first followed by the one with data (use the ignore=y) option.
The advantage of this is the total export time will be minimized.

  • How do I copy all Email messages to another system and view them seperately from any messages on the new system?

    We're giving my wife's old laptop to our children. We have already set up her E-mail accounts on the new laptop which is now 2-3 months old. While cleaning off the data from the old laptop, I have found hundreds of Emails that I want to save for future use. I just archived the old messages tonight. How do I copy them to an external drive so we can read them later without writing over all the new Emails on the new laptop?

  • Unresponsive system when copying large files drive-to-drive (x86_64)

    I'm running Arch x86_64 on a quad core Xeon processor/P35 motherboard w/ 4 gigs of RAM.  I also have two SATAII, 7200 RPM HDDs.  For the most part, Arch is a VERY responsive platform.  I am noticing some really odd unresponsiveness that only happens when I copy large files from one hdd to another hdd.
    Symptoms:
    -Mouse cursor skips (doesn't move smoothly)
    -Windows such as firefox or shell don't move smoothly across the screen if I move them
    -Keyboard lag - as I type this post ) my fingers are going faster than the text is appearing
    Once the copy is finished, everything is normal again.  I swear I read someone else reporting this behavior, I just can't find it. Two questions:
    1) Is normal for the x86_64 kernel?
    2) If not, what can I tweak to remedy it?
    EDIT: Ack!  Found the post I remembered reading:

    if the file is bigger than 4gig(uncompressed) then u need swap partition, as the first thing it does is copy the file to memory and if it overflows it is bad. then your server is 1/3 options, either server/middle/desktop. if it is server, it doesn't care what framerate u get on X. then there is the timer. I'm running mine at 300 but arch's default should be 1000. the higher it is the more it "checks" what needs to be done with files, events, etc. then there is the file system type and block size factor. if ur block size is really low like me(1024k) then ur hd has to write more times(on and off) just to write out the huge file. so for huge files, format with huge block size(4096k?) so that the hd does less work.

  • RFC users locked after system copy in production system

    Hi,
    BW_User,MDBTC(RFC users) system users were locked in our BI Production system at the same time system copy activity was running in the Quality system(production to quality) so as per our colleagues concern after system copy they started Quality system with out changing background work-process 0 so some jobs were triggered which were copied from production system.
    Is there any cause to lock RFC users in production system for system copy? If there is any other reason where we can check logs
    Thanks
    Jalandhar Reddy

    Hi,
    Well maybe i am wrong to analyze your problem .
    Anyway I faced this issue to in our system before and we found that one background job was running  in a system that has basically  prompting an RFC connection to another system. In the t.code SM59 and there was wrong password was put in.We just reset the password and it was worked fine.
    You can try for this..

  • Copying Production Database to another location

    Hi,
    We are currently upgrading to a 11g and as part of the process I need to copy our production server 10g to our new hardware. I want to carry out a couple of dry runs to get timings and test the process. I will be keeping the same SID.
    Are there steps I can take to isolate the copied oracle database to ensure it does not try communicate with any other systems.
    I come from an SAP background and in SAP there are a number of steps to isolate a system. I'm looking for similar steps that would be used in oracle e.g.
    stop job scheduler
    stop all inbound and outbound communication
    Lock interactive users
    Stop outbound email
    etc...

    Somwhat dependent on your method of creating the new database on the new server, but if you don't start a listener on that server, no one that is not directly logged on to that server will be able to connect to the database. As for outbound connections from the database, you might have to get a bit creative, depending on where and how the outbound connections are defined.  I'd start by not haveing a working tnsnames.ora file.  Then check the defintions of any db links in the existing database.  If they hard-coded destinations, make sure those destinations are un-resolveable/unreachable from the new server.  I wouldn't worry about the job scheduler during the dry run.  As long as there is no outside communication from them, who cares if they run?  With the listener shut down, no outside users can connect, so no reason to lock user accounts.
    Perhaps you could cover all bases at once by simply configuring the firewall on the new server to disallow any communication at all ...

  • Clipboard issue- Automatically copying content past into another system across the network.

    Hi,
    I am facing issue related clipboard in all windows platform in our organization. Say example: Person A copying something from any application or browser in his system and when he is going to past into another apps(word file or text file) in the same system,
    its pasting some other text content, which is copied in another system, which is using by person B. Again Person B when is going to copy and paste something in his system, pasting content is from person C's system. It is happening in all system in our organization.
    It is very terrific problem, which is seen first time in my life. It is happening intermittently in all system.
    Our organization is mainly R&D and software development company, Developers using windows clipboard in local system, but not
    in another system thru n etwork or LAN. I have installed updated windows patch, Forefront antivirus in all system and also run scan. Not found any virus. We are continuously trying to identify the issue. Yet we did not get any solution.

    Hi Nirupam,
    This is weird. Please disconnect the network from these computer to check if they work fine.
    This is also might be caused by some third-party software conflict. In such situation, I would suggest you perform a clean boot in Windows clients to rule out the cause of third party programs.

  • Copying Report Programs from one SAP system to another SAP system

    Folks,
    I would like to know if there is any easy way to copy a report program from one system to another system. There are two SAP systems of which one runs on UNIX and another one runs on Windows.  BASIS consultant told that they are not transportable.
    The only option I came up with manually copying the reports and associated Selection Texts, Text Symbols & Titles& Headers.
    Is there any other easy way to do this task as I have 60 programs to be moved. 
    - Balaji

    Thomas,
    There are two SAP systems of which one runs on UNIX and another one runs on Windows.
    Thanks for your suggestion. Our BASIS consultant mentioned that as the Operating Systems for these SAP systems are different , transports can not be done.  As per your suggestion , my understanding is that transports are possible even the operating systems are different.
    Please confirm.

  • Copy a program from one sap system to another

    hi all,
       i need to copy a program from one sap system to another..along with the text symbols, selection-texts and includes without any transport request release...how can i do that?
    thanx in adv

    Hi,
    You need to Download the Program first in to Local desktop then upload the same to another server, we can not move the code directly from a server to another server without a Transport request.
    but you can call the program from other server using RFC destination, create a RFC for that server and create a function module in the server which the program is there and use the SUBMIT statmet in that function module, then from the other server call this function module using RFC destination

  • How to copy a table from one system to another system

    Hi all,
            can any one say how to copy table from one system(sys1) to another system(sys2).
    regards,
    nagaraj

    There are many ways.
    1. Use the already existing transaport request number for that table to do the transaport (Active)
    2. Create mannual transport request from SE01 and in the object list enter following
    R3TR -- TABI -- <Table Name>
    And do the transaport.
    3. Ask your basis consultant to do the transaport from oracle layer.
    Thanks,

  • Why does my block diagram change when I copy my code to another system?

    I am doing development work on a laptop on Win XP and using LabVIEW 2009 with service pack 1. When I copy the code to the target system, my block diagrams are changed and no longer fit the screen. Much of the code is spread out, mainly down. The target system is running Windows 7 and also has LabVIEW 2009, SP 1.
    I notice that any constants that are clusters are expanded when copying the code to the other system. I've gone in and turned off the autosizing for these clusters but they are still expanded. I like to shrink them to a small size for saving space.
    I've gone through and manually re-adjusted the block diagram on the target system, but when I copy it back to my development laptop, the same thing happens again. This is not an acceptable way to develop code and it has caused a real problem to proceed. I'm contracting this work and must develop this code offsite. Can anyone please help me with this? I can't keep restructuring my block diagrams every time I copy the code from one system to the other.

    Windows XP used Tahoma size 8 as its basic system font.  When MS came up with Vista, they changed it to Segoe size 9.  I'm not sure what Win 7 is, but I think it is the same as Vista.  That font change, and certainly font size change seems to be the underlying cause for block diagrams changing their appearance.  (And for front panel controls and labels as well.)
    LV seems to use the Windows system font as its default font.  Interestingly, it seems like the font sizes in LV are something like size 12, 13, 14, 15.  I think a size 9 is equivalent to a size 15, but I'm not sure about the comparisons.  (Check out this thread.)
    There are a few things you can do to try to make one system look more like the other.
    1.  Go into the Windows screen settings. In Vista, right click desktop, Personalize.  Window color and appearance.  Open classic appearance properties.  Try changing the color scheme from Windows Aero, to something like Windows Classic or Windows standard.  They both use Tahoma 8.
    2.  Or same as Step 1, but go further into Advanced button.  Pick on any option that uses font such as Menu, Message Box, Active or Inactive Title Bar and change the font there.  I'm not sure which of the items that has a font setting is the key one.
    3.  LV uses 3 fonts called Application, System, and Dialog.  I think each of those map to one of those Windows options, but I'm not sure which goes to which.
    4.  In LV, Tools/Options/Environment has a subsection called Fonts.   Those 3 basic LV fonts are selectable there.  There is also a checkbox for me which is checked and says to use default.  If you uncheck that checkbox, a Font Style button becomes enabled.  You go in there and you can choose fonts and sizes.  And the Application, System, and Dialog fonts as well as all the usual fonts names (Arial, MS Sans Serif, Greek, ....) are selectable along with fonts sizes.  Play around in there.  The whole section is very confusing, and I have no idea how it works.  I recommend going to this idea A better way to specify (default) fonts and putting in a vote.   Also this idea, Fix font behavior between windows versions, platforms & executables, deserves some love.
    5. Some of these settings can also show up in your LabVIEW.ini file.
    FPFont = "0" 15
    BDFont = "0" 13  (I think the "0" means app font, "1" means system font, and "2" means dialog font)
    Also,
    appFont="Tahoma" 13
    systemFont="Tahoma" 13
    dialogFont="Tahoma" 13
    (And if necessary, put these in your built application's .ini file)
    As you can see, there are a lot of different things going on and they also seem to conflict with each other.  I starting stumbling on the block diagram issue between working on my app on XP at work and on my Vista machine at home about 6 months ago.  I think my problem actually started with the front panel when I was trying to align labels, and use some arrow head decals on boolean buttons.  I think I did the customization of buttons in a couple different ways (because I did some, came back later to do others, and couldn't remember exactly how I did it.)  As a result some decals looked different than others when I changed machines.  And I swear going from XP to Vista, or Vista to XP the problem got both worse ways rather than let's say larger one way, and smaller the other way.
    Replying to your message is about as much to me trying to combine all the pieces of knowledge I've stumbled across over the past months and year as it is for trying to help you.  Hopefully, this information gives you some places you can look at and play with.  (I bet #1, would be a quick, easy way to solve your immediate problem, but I haven't really tried it myself to be sure.)
    I hope someone from NI who has a better understanding than me about these font issues could jump in and correct any mistakes I made, or add anything I might have left out.  What we really need is some sort of "nugget" or National Instruments white paper that really explains all of this in ways we can use rather than us stumbling around in the dark doing things trial and error to figure it out.  Generally, any changes to the .ini files require you to shutdown LV and restart it to take effect which can take a couple minutes.  And considering all the various combinations of things that can be done above, your talking about dozens of possible restarts, and sending .vi's between two different PC's with two different operating systems, before figuring these things out.

  • How i can copy my transport request from one system to another system

    hi,
    i want to copy all my code  means( programs,tcode,class,FM...every thing.) which is under a transport request, now i want to copy all this code same as it is in another system
    eg.
    i have all my objects in for example D10 now i want all my code in some another system for e.g in D30.
    how it is possible....

    Hi Vipin,
    Check tcode SE03 for transport related issues.
    as suggested by all the TR needs to be released from the current system to make it ready to be transported to next system.
    Once you release the request ask your basis administrator to transport the request to D30.
    <b>Before releasing the request check with the basis administrator if the target system has been set to D30.</b>
