Issues of data Migration

Hello

I'm trying to migrate my SQL Server 7 database to Oracle 10 g R2 using SQL Developer (Version 1.5.1
During the migration of the data, the process is complete to halfway through due to network problem.
Is it safe to repeat the migration of data from there?
SQL Developer migration Workbench "know" when to seek where it terminus? This will create duplicates of records in the target database?
Any recommendations on the best approach to migrate the data will be much appreciated.

Thank you
wilora

Hi Wilora,

Developer SQL 'know' the migration of the previous data.
You must truncate all your tables first. You can write a quick script to do this.

SELECT 'truncate table ' | table_name | ';' From user_tables; -of course be connected to your migrated user.

Then proceed to migrating data again. Online data migration is designed only for smaller data sets, say<100 mb.="" if="" you="" have="" a="" network="" issue="" again.="" i="" would="" truncate="" the="" tables="" so="" they="" are="" ready="" to="" receive="" the="" data="" again.="" and="" use="" the="" offline="" data="" move="">

Heres a quick Viewlet of offline data move

  • The data migration to 4.1 problem

    Hi guys,.

    I've read and done almost everything in the present statutes and still did not solve my problem with the Data Migration tool.

    Everything seems to go smoothly, but once the restore is complete, I find myself in a situation where two things are are produced.

    Firstly - restored configuration is not in fact restored - vacuum.

    Second - my vCenter is proud to announce that its evaluation license has expired. Either way, it's good to know (means that at least the period of assessment and departure have been migrated).

    I am of the opinion that when I run the Backup I don't see that it backs up the license keys. I looked at the official youtube film of VMware and I can certainly see that the license information must be saved.

    Any suggestions?

    Maybe the KB article "using of the tool of migrating data upgrade to vCenter Server 4.0 to vCenter Server 4.1 fails' help.

  • Problem with the 4.1 vsphere data migration tool.

    Hello

    I guess that's the problem with trying to be an early adopt.

    I'm trying to upgrade my environment to vSphere 4.1. My old VC was 32 bits with a local SQl 2005 express (it's a lab - I don't want the full SQL version blown).

    I re isntalled on a x 64 2008 R2. No, it's fine. But empty... no license or anything like that.

    The docs say you can use the data migration tool to move the DB and config.

    I followed the instructions and after backup.bat running I get the following error:

  • [Issue] How data is transferred when you use BlackBerry (NFC) Tag? WiFi Direct? Bluetooth 2.1? Bluetooth 3.0?

    Hello

    I saw a bunch of videos of demonstration of tag BlackBerry of all the cool things you can do with the NFC, but it wondered, what happens if all my other antenas wireless, WiFi and Bluetooth, are out of?

    NFC can be used to transfer data, but it is not good for large quantities. I looked a little further and I found this cool video showing the difference to use Bluetooth 2.1, Bluetooth 3.0 high speed and Wifi Direct to transfer large files, such as videos. BB10 already does support Wifi Direct? Bluetooth 3.0 high speed?

    I hope that BB10 supports ALL the performance and maximum compatibility.

    I don't know where to post this question so here's. Please move was a better place. I think that the community needs a session of general development for wider issues.

    See you soon!

    Hello

    Tag BlackBerry, and the APIs available for developers will automatically perform the best way to transfer the data. NFC supports something called "connect transfer" and are the largest payloads or certain types of data (photos, for example) rather than by peer-to-peer NFC, NFC mode data transfer is just used to negotiate alternative transport. In the case of the BlackBerry smart phones, this alternative will be bluetooth.

    For users of touch devices, there is a brief 'conversation' between the devices on the NFC and this translates into a bluetooth connection set up and data transfer initiated through the bluetooth connection faster. This is all without the usual matching process. After reaching the stage of bluetooth devices need closer will be of course.

    The same principle applies to both 7 BlackBerry and BlackBerry 10. In fact talk us a bit about this in our latest article on BlackBerry 10 NFC API:

    http://supportforums.BlackBerry.com/T5/native-development/BlackBerry-10-sharing-using-NfcShareManage...

  • The Tungsten T3 for Palm Pre data migration

    Hello

    I am the owner of a Palm Tungsten T3. I have a lot of contacts, calendar, tasks and Memo data in I want to migrate my new Palm Pre. I saw Palm information on how to move the data from Palm Desktop for the pre, using the data transfer Assistant (DTA). However, it seems to work for Palm Desktop v6.2. T3 is not compatible with v6.2, being the latest sw version v4.1.4.e.

    When I launched DTA, I got an error. I tried several things and looked in the forums, but only to find tips for v6.2. In the end, I decided to upgrade to v6.2 in my Windows XP, but I skipped stage of synchronization with my camera (such as the T3 is not compatible). Then I run the DTA. This time, I got to the step when it asked me to connect my pre as a USB key. But after that, he tells me that Palm Desktop is installed, but contains no data to transfer. However, I can see my data in the desktop. My guess is that I could solve the problem if I could synchronize with a PDA compatible.

    Can someone give me a hint on how to transfer data to my pre of my T3? Is this possible at all?

    Thank you

    You will not be the Tungsten T3 or the Palm Desktop 6.22 Pre - synchronization you will use as a vehicle to move the data into your pre.  I suggest that you use the command Export of Palm Desktop 4.1.4e for export data PIM (Contacts, calendar, tasks and Memos) out as a file in comma-delimited (.csv) as a backup before installing Palm Desktop 6.22 as the data upgrade process can not be cancelled.  If you need to go back to Palm Desktop 4.x and do not have a backup, you will be out of luck.

    After you have backed up your data, I upgrade to Palm Desktop 6.22, DTA can migrate your data in the meadow and then synchronize the Pre with a Google account to access e-mail and calendar.

    To fix your data problem in the second part of your post, you can try to install free third-party utility, PalmHotSyncSetup.  This changes the Windows for Palm Desktop registry keys so that he could support the older devices like the Tungsten T3.  You can download PalmDesktopHotSyncSetup from Pimlico Software Web site.

  • Data migration of EBS to 12.2.4 EBS 11i

    Hi all

    EBS 12.2.4

    RHEL 6.5

    We migrate our EBS 11i to EBS 12.2.4. Can you help me please what is the correct procedure to migrate data?

    For example in the GL/tables schema in 11i, assuming that our functional did the GL R12.2.4 module setup.

    How I extracted the tables in the schema of GL 11i database and load it into the scheme of database R12.2.4 GL?

    Is it possible that the data loader itself will be to install the module GL R12.2.4 based on configuration data extracted from the 11i database?

    Is it possible to copy the configuration in 11i and fill on R12.2.4?



    Thanks in advance for your kind cooperation.


    JC

    Hello

    You can do this by using WebADI.

    Since you are going to extract only the balances so this task will be easier in extraction and loading.

    The tables of the interface of 11i and R12 are not very different.

    Almost the same method used by entering data in 11i usable in R12. The data to be loaded will be on spreadsheets prepared by users and validated by the business consultants.

    The application developer should not take the data by itself and insert it into the new system.

    You can do a quick search and find lots of resources on the topic.

  • Oracle - principle of cloud data migration

    Dear Experts,

    We intend to migrate data to oracle on site to the cloud.

    Due to the nature of the data that we'd spend only snapshot of the last 1 year 6 months to cloud and archive rest all data.

    Question:

    Size of the data to be archived is 630-650 GB. We would like to migrate this data to a generic rather than the .dbf file format, so that we can port these data in any technology as and when necessary.

    I would be interested in any suggestions on the best approach to achieve the same.

  • Return of OUD to ODSEE data migration

    Hi guys,.

    I work with one of my clients on the migration of a bunch of parameters ODSEE of OUD. During deployment, we arrived at the front door running and everything was fine runnign as it should.

    For some unknown reason, however, the ODSEE suddenly began to refuse updates, and we therefore found ourselves in a scenario where the OUD had data more specific that would be rejected by the ODSEE through the gateway of the replication.

    We wanted to reset the ODSEE with the OUD data form, but that there is the ds2oud tool and the export of substances on the side of ODSEE, y at - it an option or a tool for generating a LDIF friendly ODSEE?

    Thank you very much

    Olivier. /.

    A more information: currently there is no tool to adjust entries OUD reimport them in Department and keep the replication metadata.

    An option would still be to export entries to OUD (export-ldif) and use the-e option to filter the attributes of replication metadata specific oud.

    OUD exposes the entryUUID. Which equals ODSEE nsUniqueId, but the format of the value is slightly different, so the nsUniqueId will need to be adapted with a script.

  • VLDB (30 TB) NonRAC ASM data migration

    My client is running 10.2.0.5 database that is TB 30 in size. Its HACMP/PowerHA with an active/passive configuration.

    Customer wants to migrate this database to the ASM. They do not take backups rman due to the size of the database and bcv backup technology-dependent. Customer wishes to know what is the best way to make this migration with minimal downtime and risk.

    BCV uses the copy on write technology and advanced technical mirroring. A BCV can be used to resynchronize the data, or it can be detached from the separately mounted and active data storage for offline processing.

    If a full restore of an object or a clone of previous device enough so it can be a quick recovery. However, some implementations, like EMC Timefinder/Snapshot are not suitable for the recovery because they depend on the existence of the original data source.

    In any case, I think that BCV technology provides only a very limited way for Oracle database backup, because it duplicates data errors and not suitable for advanced database, rman or tablespace restoration and recovery. A database of 30 to may take your time for RMAN, that also depends on what kind of database, it is and, for example, how often a full backup is required, but it can be done.

    About the NAS, it's just an example to show that there are affordable storage solutions and it doesn't have to be expensive EMC storage systems. I don't see why such a solution cannot meet controls data center very strict regarding the technical aspects.

  • Data migration to thin warehouses

    Hi all

    I'm new here and for PowerCLI, so I hope that my question is not too restorative!

    We decided that we should probably be thin-commissioning to the layer of VMware and not at the level of the SAN layer. Unfortunately, it is not a way to inflate all of our thin LUNS on our VNX to convert them into thick LUNs. Fortunately, it's a new environment with only a few tens of VMs, so it does not seem a big deal to make the change. My plan is to:

    1. create a new logic on the SAN unit number and present it to VMware

    2 migrate all our virtual machines off the LUN existing (there are 8) for a new LUN, and in the process, convert thin in data warehouses

    3. delete the original LUN 8, recreate them as thick as re - LUN to VMware

    4. migrate the new LUN data warehouses.

    I know I could do this manually but I thought it would be a good opportunity to use PowerCLI. I move all the VMS names begin with "064", so I hope for a script that will migrate all 064 * VMs to the new data store and convert them to the thin.

    Can someone tell me what would be the command to do this?

    Thank you

    Fergus

    Basically, you can do all this with the Move-VM cmdlet.

    $newDS = get-Datastore-name MyDS

    Get-VM-name 064 * |

    Move-VM - confirm Datastore - slim - DiskStorageFormat $newDS: $false

    In the $newDS variable, the object representing the new data store you want that all the VMS to.
