Migration of the Exadata

One of our architects of data consulted some Oracle resources and asserts what follows as a migration route valid for our existing platform to Exadata DB Machine and I just wanted to know if its real/valid:

1. turn of Exadata via a parameter (as a parameter database, except for a parameter of the exadata software?) such that it behaves like a software JBOD and not 11.2 Exadata giving grid discs (I guess).
2. install and configure no Oracle 11.1.0.7 RAC on Exadata DB nodes using storage for the ASM of JBOD (cripple Exadata cells)
3. migrate our databases more in this new database on the paralyzed Exadata DB Machine
4 go to 11.2 RAC
5. turn on Exadata via the parameter

I could be off on the accuracy of the wording of the steps, I'm paraphrasing and he doesn't have to remember the exact details, but above is the idea of high level. If you have corrections (assuming it is correct / valid) Please correct as I am more interested in this as a method.

Thank you.

Not valid at all. You must run DB 11.2 on Exadata, no way around that.

We wrote a whole book on migration to the database machine. I would say from here:
http://www.Oracle.com/technetwork/database/features/availability/xmigration-11-133466.PDF

I also suggest upgrading to 11.2 as a separate activity so allow your environment and the timeline. In this way, you can separate the problems Exadata 11.2 related instead to bite them both at the same time.

    I recently bought a HP 15 laptop with 8.1. I use mainly desktop with latest Mozilla.

I am 75 but strive to keep abreast, but it baffled me.

    Sorry, it's a question of support of Windows, the Windows taskbar does not part of Firefox. I do not use Windows 8.1 myself, and I don't know if the process is the same as on my Windows XP - but maybe click and hold and drag this bar down might work like on Windows XP.

  • Migration of the OMF

    Hello guys,.

    I'm in a phase of migration of OMF files and configured in my pfile file as follows:

    * .db_create_file_dest = ' / DG_PRODUCTION'

    * .db_create_online_log_dest_1 = ' / DG_PRODUCTION'

    * .db_create_online_log_dest_2 = ' / FRA_PRODUCTION'

    I used the following command:

    RMAN > RUN {

    SET NEWNAME FOR DATABASE AGAIN.

    RESTORE THE DATABASE;

    SWITCH DATAFILE;

    RECOVER THE DATABASE;

    }

    RMAN > ALTER DATABASE OPEN RESETLOGS;

    When you are finished, I consulted:

    SQL > select name from v $ datafile;

    NAME

    -------------------------------------------------- ------------------------------

    /DG_PRODUCTION/BD/datafile/o1_mf_system_c7ytmpqn_.dbf

    /DG_PRODUCTION/BD/datafile/o1_mf_sysaux_c7ytmps5_.dbf

    /DG_PRODUCTION/BD/datafile/o1_mf_undotbs1_c7yl7ltl_.dbf

    So far, ok. !

    SQL > select name from v $ controlfile;

    NAME

    -------------------------------------------------- ------------------------------

    / DG_PRODUCTION, BD, controlfile, o1_mf_c7yk6tol_. CTL

    / FRA_PRODUCTION, BD, controlfile, o1_mf_c7yk6x0n_. CTL

    So far, ok!

    but

    SQL > select Member from v $ logfile;

    MEMBERS

    -------------------------------------------------- ------------------------------

    /U05/BD/redo03.log

    /U05/BD/redo02.log

    /U05/BD/redo01.log

    the migration of the log files have been migrated to DG_PRODUCTION and FRA_PRODUCTION that I specified in the pfile file?

    the correct would be:

    SQL > select Member from v $ logfile;

    MEMBERS

    -------------------------------------------------- ------------------------------

    /DG_PRODUCTION/BD/onlinelog/redo03.log

    /FRA_PRODUCTION/BD/onlinelog/redo02.log

    ??

    SET NEWNAME applies only to the database files, log files redo not online.

    You could issue commands ALTER DATABASE add LOGFILE without specifying the path to Oracle using the defined online_log_dest

  • D2k migration to the latest platform

    Dear friends

    Nice day

    We have a challenge, I need your expert advice on the following points:

    1. So far, we are using Oracle 9i + D2k on Windows Server 2003 32-bit.
    2. Our database, forms, and States have been for the past 15 years and its been created with many controls according to the requirement of the company and works very well.
    3. Now we want to upgrade our server to windows 8 and all users have started using Windows 7 and 64-bit Windows 8.
    4. This application will not support for the 64-bit platform.

    1. I want to know what will be the migration of the existing process later. (Database, forms, and reports)
    2. What type of license is needed and about what will be the cost per user.

    I will be grateful if I can get a clear suggestion that will help me to discuss with management and to plan accordingly.

    best regards

    Sandy

    I'm a bit confused of your real environment. You have Forms 6i and Oracle 9i database?

    If so, there is a change architecture of 6i to the current version of 11G. Cleint server-based forms 6i and you had a client installation of runtime-forms and actual execution of the forms was on the client. With 11G you need to a Weblogic Server where forms are executed on the client only the GUI runs as a java applet.

    There are several built-in the forms 6i who no longer work (for example RUN_PRODUCT) and the other is no longer runs on the client, but on the application server (for example, HOST or OLE2).

    Migration effort depends heavily on what features you are using in your application.

    I suggest you take a look at the documentation here form of Oracle

  • Extremely high latency during the migration of the local data store to data store shared.

    Hi guys I hope you help me. Sorry for my English btw, I'm not native.

    Let's start!

    I have:

    1 vCenter
    1 host
    1 Distributed Switch (with a pg for managing network/IPstorage the esxi)
    1 standard switch (empty)
    1 FreeNAS to provide iSCSI LUNS
    1 Microsoft to provide iSCSI LUNS

    When I try to migrate virtual machines between the warehouses of shared data or data shared at local store, all right. The problem has become when I try to migrate virtual machines from the local to the shared data store. All data stores down (all paths down) and back up and I get this error:

    "Error caused by the /vmfs/volumes/volumenID/VMDirectory/Disk.vmdk file.


    When I try to migrate virtual machines from the local to the FreeNAS iSCSI data store it fails immediately.
    When I do the same local Microsoft iSCSI datastore that it takes a time loooooong to migrate the virtual computer, give it to me even all the paths downwards and uplinks down error but not lacking in migration.

    I'll give you some screenshots to see the errors.

    Thank you very much!

    EDIT: I have extremely high latency notice when I try to migrate from the premises of warehouses of shared data. average 2000ms with peaks of 50,000 (see my response below for more information)

    Finally, I found the solution! The problem is that I have been using E1000E vmnic instead of vmxnet3. I have configured an adapter vmxnet3 and boom! 20 ms in all migration!

    Thank you to all for help, especially Nick_Andreev !

  • Migration of the individual components

    Hi all

    After DEV and PROD at APEX 4.2 environments, migration of the individual pages/components fails with the error integrity constraint violation

    Can someone please advice me on how I can solve this because I don't want to migrate all of the application each time

    Thanks in advance,

    RD

    Regardless of whether the page exists or not, it is the user interface of the page.

    I would recommend the migration of the entire application after an upgrade - there may be information about post-upgrade practices in documentation.

    I would say that update generated apex_appl_user_interfaces relevant environmental records, and now they do not match up - where the foreign key issue.

  • Update Manager error after migration of the database to a different instance.

    Hey everybody,

    I've migrated the SQL Express databases to the named instance of SQL Standard.  It's all 2008 R2.  The three migrated databases were VCenter, VirtualManagerDB and VSphereUpdateManager.  Domain in SQL accounts have been migrated to the new instance of the box.

    Now, I get this error when trying to open VSphere:

    Call 'ServiceDirectory.QueryServiceEndpointList' of object "ServiceDirectory" on vCenter Server '192.168.123.160' failed.

    Can someone help me understand this?  This is an installation VCenter 5.0 on a Windows 2008R2 server that is also running SQL Server 2008 R2 standard with an Express instance and a named instance.  I've migrated from the express instance in order to overcome the 4 GB limit on the explicit instance.

    Thank you

  • Cannot migrate through the required network. Someone please...?

    I've set up 3 ESXi hosts connected via 2 parallel networks. One is a slower network (base 100) on 192.168.12.0/24, and the other is a speed gigabit on 10.1.1.0/24 network. Each host is to have two physical network adapters for each network.

    Home #1 Config is as follows: (also see attached photo)

    vSwitch0 (connected to vmNic0 )-> a

    -Network VM (Machine Virtual Port group)

    -Management network (VMKernel Port) vmk0: 192.168.12.30

    vSwitch1 (connected to vmNic1 )-> a

    -Network SAN (Virtual Machine port group)

    -VMKernel-Special (VMKernel Port) vmk1: 10.1.1.30

    NOTE: Host 2 also has a similar setup with a different set of IP addresses.

    My problem is that when I try to cold migrate a virtual machine from one host to another (in the left pane you see, sound of 192.168.12.30 to 192.168.12.32), he's still doing the migration through the slower network (vSwitch 0). I want to be cold migration through the fastest gigabit set to vSwitch network 1.

    I have not yet tried make clusters or vmotion, because I can't seem to properly configure the network I want to serve. so can you please help me with this? I want to make sure when I do the migration (migration to cold to start), happens through the network of my choice, which in this case is the gigabit network. Thank you very much.

    The stream migration cold traffic over the first Appliance for management of the system detects. In your case, there are two, with the slower network, being the first one it finds. There is no way to route based on activity, so that you either the entire network managemernt vSwitch1 or you live with slower speeds. Personally, I'm not sure that I would never have my network of virtual computer on the same link as my device/network management since they are generally two areas of different trust, etc..

    Best regards
