Best way to clone db

Hi all

I have a simple question about clone DB.

I have a big database of production (to 5). I need to clone the database for the test on the second server environment.

I'm thinking about using rma dual. All have two server can read and write to the same file system

Oracle is 11 2.0.2 version and database using asm

Can I create a new instance of cars on the second server and use it to restore db? How? Normally I restore on a single instance and after create DB and service for rac...
Do you have a tech for this doc?

Concerning
Giovanni

(1) you can take BACKUP of SOURCE database and use RMAN DUPLICATE DATABASE (or) RESTORATION method
as you have a file system shared between SOUREC and TARGET servers

(2) you can use RMAN DUPLICATE FROM ACTIVE DATABASE

(3) once, I used the CP ASMCMD command to copy the data directly to the TARGET DSO and recovered it
(it worked even our SOURCE database is running)

-Thank you

    just survived a crash of my Mac Pro desktop computer.  Waiting for a GeForce GTX 680 replacement graphics card.  I need to create a sustainable clone, course of my boot drive.

    Carbon Copy Cloner has a very nice interface for the selection of the trees of subdirectory to copy.  Of course if you do not include the operating system, it will not be a bootable clone.

    CCC has a fully active 1 month demo mode.  The saved data is good forever after the demo expires.

    Personally, I just do a full 100% clone and then choose what to restore later.  For this

    Carbon Copy clone

    SuperDuper (a full clone is always free; updated to incremental update of a clone and backup schedule pay you for)

  • Best way to make my SSD works again with a single partition

    There are 2.5 years, I replaced the original on my computer with a SSD hard drive. Months after I installed the beta version of Yosemite, the latest operating system for Mac at the time. To do this, the system created a partition on my drive, in which he has installed the beta version of Yosemite.

    I have today on the same partition, I installed Yosemite, Sierra macOS running. In the other, I have all files, so I want to eliminate. However, when I try to do this by using the disk on my Mac utility, it is not possible; I get a message that says I can't delete the first volume of the disc. When I try to increase the size of the partition on which macOS Sierra operates, so reduced the size of the other, the system won't let me.

    I would like to know what is the best way to make my SSD works with only one partition.

    You cannot delete the last partition that was created, that not 1.

    You can clone the content from the 2nd to the 1st, then you can remove the 2nd.

    Do you want to be a second backup or you simply want to move to the larger disk? The quickest way would very probably be use Carbon Copy Cloner to clone one to another. If you want it to be different from other data store you on the largest disk (not recommended), then you will need to create a separate partition for backup to disk with greater capacity.

    You can also clone volumes using restore in disk utility.

    1. Open utility disk from the Applications\utilitaires folder.
    2. Select the volume target in the list on the left.
    3. Click the restore in the main window of disk utility.
    4. Select again the volume target in the list aside and drag it into the Destination field.
    5. Select the volume of the Source of the list aside and drag it to the Source domain.
    6. Click Restore.
  • What is the best way to edit the pixels of the layer without applying the image?

    Help, please!?

    What is the best way to change the pixels on a new layer (clone, healing, patch or selection) without applying the image? When I do that, I can't change the under layer if I make a mistake.

    Does this make any sense!

    You want to use the patch tool to put the fix on its own layer? Use sample all layers in the Options bar.

  • Best way to determine the amount of disk space is required for a deployment of office?

    We are conducting an assessment on the Lake and he examines disk space total used by our desktop computers, but I want to determine how much space SAN we need for our driver. What is the best way to understand this assuming we go with linked Clones, but have yet to determine how many bases we have pictures...

    It is counting on the OS and the numbers of virtual machines, for linked clone images, you might need a few of them, one for the standard user, one for the user of the task and one for users with power "admins".

    Also, is that the application will be with the operating system or using ThinApp?

    All these he had to be consider about before you go to the design of the storage, think also about having the SSD in your host supported replica image "linked clone.

  • Better way to clone the hard disk SSD evo 850 samsung

    I want to clone my current HARD drive to SSD samsung. The problem is that the OEM partition (100 mb) is not cloned with the Samsung tool. What is the best way to keep that partition? Should what tool I use? If I do a fresh install of windows 7 with the Dvd from Dell, it will recreate this hidden OEM partition? Thanks for your advice.

    I've used easeus http://www.easeus.com/disk-copy/ succesfully maintaining OEM partitions and recovery.

    I used it to cram a 750 GB HARD drive which had plenty of free space on a 250GB SDD while preserving the OEM partition with the diagnoses.

    I used a USB to Sata adapter and it was really easy.

    It goes without saying, but... BACK UP DATA THAT YOU CARE ABOUT THE FIRST...

  • Best way to extend the partition?

    Do you have a Server 2003 P2V to new hardware.  I used Acronis to clone the server cold, created a new virtual machine, restored to the virtual machine with Acronis, configured with VMWare Converter and then add the VMWare tools, etc.  Everything seems to be fine, except the food not extend the partition.

    I put a partition of 100 GB for the virtual machine, but restoring recreated the original score of 68 GB and another 'unallocated' 31 GB.

    What is the best way to extend the partition, so we can use all of the 100 GB?

    Thank you for your time.

    If a C: partition, you can use extpart, but a c partition: no, you can use the construction in the diskpart tool and extend. With one exception: If you have multiple partitions on a single HARD disk, you will need to use VMware Converter.

  • What is the best way to make the uniform skin (not necessarily blur it!)

    Hello

    I have some photos where the skin of the leg of the model is not uniform brighteness. Without this vagueness, I tried the clone stamp, but it is very difficult not to introduce new variations of brightness.

    What is the best way to make the uniform skin of brightness (in fact, the same color!)?

    Thank you

    I know EXACTLY what you mean.  I was doing something exactly on these lines just yesterday.

    It is not trivial, but it is doable.

    For 'hard points', you can try the Spot Healing Brush first.

    But here is a tip that I use sometimes which may well increase overall finesse:

    1. select just the surface of the skin.

    2. selection a little market and soften the edge, just to make sure that you don't mess the edges.

    3. median filter - noise - and set the RADIUS to be big enough.  Look at the image to see the level of smoothing.

    4. change - bland and knock back effect, while it is not perfect, but makes a subtle improvement.

    Then, for clearing-up soft darkening, try the burn and Dodge tools, at a low level of exposure (and possibly with Airbrush Mode).  Work slow.

    Cloning with low opacity can sometimes help as well.

  • What is the best way to buy an iPhone Unlocked 7?

    Hi all

    I am currently using T-Mobile and want to get the new iPhone 7. Since there is no option for a sim-free iPhone, what is the best way to buy the new iPhone? Should I get the T-Mobile one full fare? I know that he will be released version but it will come with a T-Mobile sim so what will do with the sim card? Put it away or give it to T-Mobile? Or should I wait for the version without card sim to appear, which I don't think that will come out until November, and I don't want to wait that long.

    Thank you in advance.

    If you do not want to wait to pay full price for the model from T-Mobile.  You can do whatever you want with the SIM card.

  • Cannot repair the photo library. The best way to restore from iCloud library?

    The photo library of the system is damaged and cannot be repaired.

    It is said "Photos has attempted to repair the library"Pictures Library 2015 ", but can not open it." .


    I first met problems with this library a week before and at the time where I could repair and open the library successfully, but lacked a month value of photos.

    Given that it was successfully in the iCloud library, I left it to re - sync - but this process suspended several times before the end, and the photo library of the system now seems to be permanently damaged.

    I have no project of marked or impression of faces in the photo library of the system, then I would be happy just to restore from iCloud.

    My plan is to put in place a new - empty - library and then that designate the library of the system.

    If I understand this right, the new (empty) system Photo library will now resynchronize with iCloud and will copy all the contents of this library of back to my Mac.

    Is this correct? It is the most effective way to restore my library?

    And while I'm here - what is the best way to manage a very large library? I had my photo library become corrupted ten three or four times over the past years and have found it necessary to divide into single years to prevent this. I overlooked this piece of household by the end of 2015, and now it's happened again... Surely, there must be an easier way to manage libraries of images of several years?

    Is this correct? It is the most effective way to restore my library?

    Yes, if you don't have a useful upward on your Mac.

    How do you call a large library, I've never had a corrupt Library, I think that your problems are not the result of the size of the library, but rather something else. From my experience it is recommended to maintain a local upward, I use Time machine, but also have a second to the top using a third-party backup solution.
