Parallel import

Hi all

I want to migrate our Database 9i to 11 GR 2.

Our database is 'big' enough and I have 200 GB dump exp.

The halde has 5 large tables of size approx. 20G each.

The target server has 8 CPU and the disk has 1 TB. The disc is quite ordinary 1prediction.

My question is... Can I run a parallel importation of 5 large tables? So I can maximize the 8 core processor?

My problem is the only drive that could have a quarrel of e/s?

Sould I run one at a time or in parallel?


Ideas please...


Thank you very much

As you have only 1 disc, if you could use parallel execution, your query slaves will strike only one disc.

As if 1 disk can not support readings and the simultaneous sessions. Think of 5 users making written on 1 disk. Is not possible?

  • Parallels-import: Dual Core = single core?

    Hello

    I try just VMWare Fusion (any Parallels 7 VM), everything works rather smooth and fast compared to the Parallels, but when I run Dragon Naturally Speaking, I thought that the profile has been initially registered with a processor dual-core and now I would have a single processor Core, and that it would mean a loss of recognition quality and performance of this software.

    Well, you see, I'm rather new to VMWare Fusion, but I would just like to know what to do to remedy the situation (if possible without reinstallign the heap).

    Best regards

    1. what change I do when importing from version of source database and target are different?

    You don't have to do anything. You export metadata that will be recreated in your new database, and the new version. Just run the import command.

    2. do I need to change something in my order of import?

    I don't think that you need to change anything. A parallel add if you want, but parallel import does not match the parallel export, so keep it as you will be fine.

  • touch screen does more than a few days after the release of Marshmallow.

    Hello.

    I ask for some advise the issue I'm having with my z3 compact.

    I was really happy, the phone never had problems, and I always have the software updates as soon as they are available.

    Now the phone has 3 days until the end of the warranty and a few days after that update Marshmallow, the screen stopped responding to touch, I couldn't turn off the phone or made a backup because the phone is locked.

    I was able to turn the phone off using the power button / stop and continuous volume upward, but after it restarted the problem with the screen.

    I decided to do the repair of software with sony's Companion (losing all my data), but even if the problem was not resolved.

    And had upward the retailer was bought the phone's NEW in New Zealand sold the company and the new owner doesn't care... sony told New Zealand that they can not do something, because it was in a parallel importer boght... but if the 1 year warranty is international they should not be able to help me?

    It's as if this update is programmed to damage the phones in order to decide to buy a new... do you really think that would happen? I'm already regretted that I bought a new sony action cam...

    Sorry for the long text.

    Any help is welcome

    See you soon.

    @samsun
    It could be a hardware problem unrelated to the updates then, and unfortunately we cannot help you here as users with maintenance problems. You will need to visit an authorized repair shop and get your phone diagnosed by a professional.

    PS: Guaranteed Sony is not international, it is local/regional.

  • Classic BlackBerry cannot create a Mobile Hotspot on my classic

    I'm here in New Zealand with a classic parallel imported Mobile unlocked in the United Kingdom. I can't generate a mobile hotspot. I do all the things asked of me, but just scroll circle keeps scrolling. I get data and emails on the phone and I had the sim card works in an iphone and successfully created a mobile hotspot.

It is certainly in the configuration of the phone.

  • Database upgrade problem


    Hello everyone, I have a little problem. We have two (2) of a Data Warehouse and an OLTP databases. We are upgrading the database OLTP and DW this weekend. The OLTP db is 10.2.0.4 SE 11.2.0.3 SE and DW db goes 10.2.0.4 EE to 11.2.0.3 SE (via import/export). My problem is this, the OLTP database takes about 3 hours to upgrade and DW db will take about 14 hours to import (due to the fact that there is no parallelism import to the ATI). We founded to raise events on the OLTP side when something is inserted it drains to the DW database. Since there is a difference of 11 hours at the time where everyone is available over the weekend, can someone come up with a way I can raise my OLTP after 4 hours (which is the producer of the real money for the Organization) and somehow maintain the triggered data so that it can be inserted into the DW db as soon as it is available? We do not want to take a complete failure for 14 hours just waiting for the data warehouse of the suggestions? Thank you all

    Thanks John, I'll try that...

  • Oracle Data Pump

    oracle11g oracle introduced the new feature called oracle data dump. What is the difference in comparing utility imp/exp? can someone explain how to use this new feature

    for example, by using the user scott to export some tables in my diagram.

    Data pump is very fast, parallel importation is made in 11g. exp/imp sometimes fails due to problems of space on the server. but by using method of parallel import is performed. parallel importation is nothing but imported when 1 row have exported the corresponding row in the table, thus saving disk space. With Data Pump Import, a single stream of data load is about 15 to 45 times faster than the initial import.

  • Parallel degree importing Datapump

    Hello

    For several imports that I ran, I observed a constant degree of parallelism = 10 when creating index.

    Moreover, I parallel_degree_limit = en parallel_degree_policy = MANUAL CPU.

    The first parameter specifies that Oracle sets up to an upper limit on the DOP.

    If this explains the value observed?

    Kind regards

    Hello

    At the same time goes like this:

    all the tables, plsql definitions are created in series

    All data in the table of loading in parallel - so not parallel insertion into a table but a work process separate datapump by table - so EMP would be charged by slave1 and DEPT by slave2 - but at the same time. IN your case 10 separate tables would all be imported at the same time.

    The indexes are built at the same time you specify

    Constraints are made in series one and the same process, I think

    I wrote a short blog about it earlier that can be useful: it contains pictures! :-)

  • Fusion 8 trial goes wrong - Win8.1 VM, imported from Parallels, does not start

    I was pretty many small problems with Parallels, so I thought that I had trial VMware. After importing my Parallels VM, it does not start in Fusion. A few details:

    Fusion 8.0.1 - 3094680, downloaded today VMware.

    I installed it, accepting all the defaults. Let him import my Parallels VM work. From the first test, wouldn't start Windows. After using Windows for many years, I am familiar with its built-in startup repair functions, so I followed, as follows:

    All down took place inside the virtual machine in the virtual machine window, at the start of the first attempt.

    "Your PC came across a problem..." »

    "Automatic repair".

    "Diagnosis of your PC", which recommended that I just tried the reboot, so I did.

    "Your PC came across a problem..." »

    "Automatic repair".

    ""Diagnose your PC' this time, I chose Advanced Options > troubleshooting > Advanced Options > startup repair, which took me through "diagnose your PC", check disk for errors, ""repair disk errors. That has not helped - I found myself at the beginning: "Your PC came across a problem..." »

    I tried again the whole process and am still unable to boot: "Your PC came across a problem..." »

    Oh, my Mac is a MBP, the model of 2014, the 16 GB of RAM, a Yosemite OS X fully updated running. There are about 150 GB of SSD disk space, and the virtual machine is set to 8 GB of RAM.

    Any ideas? I'll be happy to check if suggested things and report.

    The first thing I would try would be to uninstall the drivers/additions/tools from inside the virtual machine before you import it - that is to say from inside Parallels.  Have you tried?

    Check that Parallels knows that it is a virtual machine Windows 8.1 (or the closest guest OS type he understands).  We rely on the knowledge of the OS type asked to perform various tasks during the import, and we could get confused if it is not correctly set prior to importation.  By the way, check what disk controller, we chose to use for the virtual hard disk.  SATA is probably the safest option, but I can't predict with certainty how it works if you use a type of controller of different disk for the virtual machine in Parallels.

    I hope it's useful!  Feel free to post them here if none of these solves the problem.

    See you soon,.

  • Import parallel-VAPP Limitaion

    Hello

    I'm trying to deploy several OVFs in parallels using the import-VAPP powercli.

    The first 1 I am deploying returns as expected, but when I'm deploying seconds an it just hang until there finishes although I use the RunASync indicator.

    Anyone know if there is no limit for the deployment of several OVFs at the same time? Is - this configurable?

    Yes, it is an option... I'll look into that.

    Thanks again for your help! You have really helped my out here.

  • Import of Parallels

    I want to try VMware Fusion to see if it solves a problem I have with a soft under Parallels, but I have a concern. In some reading that looks like the Parallels image is rendered unusable return to Parallels, if I decide not to use VMware. In the application itself, however, it is said that import creates a copy. So the question is I will end with two images, one for the existing to Parallels and VMware? I don't want to take the risk of trashing Parellels since I already have a number of installed applications.

    TNX!

    When you import, you will receive an option to choose a location where the converted image is saved. In the end, you will have a picture format by merger.

    Parallels image will be always available in its original location.

  • Imported the Parallels VM, now I get "BusLogic SCSI adapter is not supported for 64-bit customers."

    I have a virtual machine 64-bit Fedora 16 that I use in Parallels Desktop.  During my first installation of VMWare Fusion 5, I had the opportunity to import this VM.  I did that, but when I boot, the virtual machine is suspended.  I went to the configuration of the virtual machine in VMWare and fixed a few things than the failed import.  Now I when I start the VM, I get this dialog box:

    The BusLogic SCSI adapter is not supported for 64-bit guests.

    I searched on the web and this forum, and I can't find information on solving this problem.

    I do not necessarily first as suggested by the other answer on this subject and instead, add the following line to the configuration of the Virtual Machine's .vmx file.

    scsi0.virtualDev = "lsilogic"
    

    This should fix the error message that you get without having to directly edit the hard.  Take a look at: changing the file .vmx for your VM from VMware Fusion (1014782)  

    That said, if you want detailed according to the existing real configuration recommendations then... To help understand what components are, how best to provide comprehensive diagnostic information is to use the command "Collect information to Support" the Fusion of VMware (menu bar) > help > collect Support information and then attach the .tgz file it created on your desktop for a response post.

  • Import of Windows 7 Parallels 5?

    Hi, I just got VMware Fusion and tries to import a Virtual Machine of Windows 7 Parallels 5. When I try to do, I get the message "the virtual machine is running or paused. Shut down the virtual machine and try again. "But Parallels running at all. Restart, opening and closing Parallels do not seem to work. Can anyone help?

    (Mac OS 10.7.4)

    Have you shut down the virtual machine (not parallel) or simply hang it?  You have snapshots created in Parallels?

    FWIW, conversion of VM a questions - you might be better off installing VMWare converter inside the guest and then use it to create a new machine virtual merger.

  • Import VM to a parallel

    I had a few problems with Parallels 6 so I wanted to try VM Fusion.

    My Parallels virtual machine is 40 GB. When I run Fusion VM it tells me I need only 41GB for importation and I 167 GB free on my machine.

    When it tries to import, it still fails telling me I have insufficient disk space.

    A few times I checked on the file Fusion VM created and it was more than 112 GB.

    Then... I'm confused as to why the estimated amount is less than what it really is creating up to 4 x. Is there anyway I can get this importation occur? How much space do I really need?

    In Parallels remove all your shots, disable "SmartGuard',"Disks of cancellations"and deselect all shared folders with your Mac.

    After doing this closes your machine virtual Parallels (not "Suspend" etc.).

    Then import the virtual Parallels in Fusion machine.
