How the level 0 and level 1 backups are related?

Version: 11 g

I was going through the scripts in the post, two issues related to the RETENTION STRATEGY


When you have a differential incremental backup strategy and when you run scripts to backup of level 1 and level 0 via cronjobs different from Sunday to Saturday, during recovery, how RMAN will identify all these level 1 backups and backup of level 0 parent as a single unit? In level 0, and its backup scripts later level 1, I do not see a clause that links the level 0 backup and its subsequent backups level 1?

Hi Steve_74,

How RMAN will identify all these level 1 backups and backup of level 0 parent as a single unit?

Information used during a restore comes the controlfile.

Example of
Select backup, INCREMENTAL_LEVEL
v $ backup_set
/
Will determine the backup set level 0 necessary depending on your clause of restore

Select INCREMENTAL_LEVEL, INCREMENTAL_CHANGE #, CHECKPOINT_CHANGE #.
v $ BACKUP_DATAFILE
When file # = 1
/
Will determine what (s) to apply to the datafile 1 according to your restoration clause.

Kind regards

Tycho

  • Need help for the restoration of the level 1 backup

    Hello!

    I am trying to create my database on a new server using hot rman incremental backups.

    I already restored and retrieved my database of level 0 on the new server, but I am not able to restore/recover the level 1 backup of the new server. I transported irom backup level 1 the old server to the new. What I need to get lvl 1 bkp only or also to restore it.

    Can someone help me on this problem by specifying the steps to restore/recover backups incremental level 1?

    Thank you!

    If the recovery has been completed and "tables are not present", this means that the tables were not present at this SNA. Either they were created after the SNA GOLD were dropped from the later the RCS.

    You must have block change tracking for restoration. It is used for backups only (and it of okay if she was present or not in the backup).

  • Pavilion dm1: how the recovery 2 and 3 disc (dvd) to be bootable on USB?

    Hi, my drive hard computers have crasched so I decided to buy a new hard drive and also the recovery kit that comes as a dvd discs. But given that the computer have any dvd player I need to move the data from dvd-drive to a USB key. So I use another computer to 'move' the data between dvd and usb (I use powerISO program, to copy the data into the ISO and make it bootable on a USB key).  To make the USB bootable for the first disc is easy because it contains bootable files but I don't know how the dvd 2 and 3 to be initiated through the USB, they do not contain startup files. So I did not be longer when the recovery program stops and application disk 2. Any suggestions?

    I found a solution, and it's a simple.

    Just move all *.wim DVDs 2 and 3 files to the directory disk 1 on the USB stick PRELOAD. I also changed the information in info.dat and the SSRD.dat (place in the Repertory of PRELOAD) file to not understand anything of disc 2 or 3, if necessary, I do not know...

    Info.dat:

    BOOT

    SSRD.dat:

    NumberOfDiscs = 1
    SOURCE_ROOT = C:\RM\Image\
    UP_SIZE = 69631
    UP_OFFSET = 204800

    After that, it was only to start the computer, press ESC and select boot from a USB...

    * Note. The USB is made bootable for disk 1

  • How to remove the initial synchronization and use restore backup

    dear friend

    Hello

    I have a question about replication of vsphere

    I limit my bandwidth of the network with my virtual disk machine (vm1) is so big (1 TB) I want to know if I can do the first step to get a copy or a backup of my vm and restore on my second host then to do replication on machine (vm1) when starting replication can he understand most of the data are the second host and not do the full synchronization or initial synchronization just make changes

    my means is: I want to remove the step of the initial sync and sync just to change data

    Best regards

    what you ask is quite possible.

    Replication of Virtual Machines using seeds of replication

    To minimize the network traffic generated by transfer of data during the initial full synchronization, replication vSphere allows you to copy virtual disk files or use the files that already exist in the target data store, and highlight those as seeds of replication when configuring a replication.

    vSphere replication compares the differences on the source and target site and replicates only the changed blocks.

    When, during the configuration of the replication, you select a target for the virtual machine data store,
    vSphere replication seeks a disk with the same file name in the target data store. If a file with the same name exists, vSphere replication invite with a warning you and offers you the possibility to use the disk file existing as a seed for replication. If you accept the option, after that the virtual machine fully configured and enabled, vSphere replication replication compares the differences and replicates only the changed blocks. If you do not agree to the command prompt, you must change the location for your replication target.

    NOTE If you plan to copy the files from the source to the target, the virtual machine data store source must be powered down before you download vmdk files which will be the seeds for replication.

    Ref: http://pubs.vmware.com/vsphere-replication-60/topic/com.vmware.ICbase/PDF/vsphere-replication-60-admin.pdf

    As the note says: power off the VM source and download VMDK who you plan to reproduce, to take them to the site data store target. When you set replication vSphere for your virtual machines, Wizard will ask you how you want to do, as if you have original seeds on the target site

  • How the processor cores and RAM work?

    I'm abit confused as to how work the processor cores and RAM work? What is selecting 2 hearts the mac was still 4 processors and virtualization of Windows is limited to 2 hearts or virtualization of Windows has 2 cores and running the CMA may have 2 hearts ? The same for both RAM and also when is suspended the RAM of virtualization Windows continue to use mac RAM?

    Kind of a newbie question, but I'm new on this and have tried searching on Google and could not find anything on this subject, it was that most do just enough carrots or RAM rather than information.

    Best regards

    -Mark

    Welcome to the community - operating system MAC will always use all the cores by default. Fusion is an application running in the operating system, and when you run a virtual machine and it needs time processor, the operating system will set the virtual CPU on a core - and if you have 2 vcpus assigned it will plan each thread on separate kernel - memory is done in the same way that the virtual machine when it is necessary the OS it will plan to the applicattion.

    When you suspend a VM from virtual machines running it will still use some memory - to suspend the virtual machine, it is better to merge.

  • Map Module: How the "Next Track" and "Previous track" used?

    I shoot with multiple cameras with a parallel tracklog in a Garmin GPS unit and think that this feature can be useful, but there never seems to be enabled. How and when it is activated? It would be nice to have an easy way to scroll the ratings the way I imported without having to pick them through the most recent or the file system.

    Thank you!

    As far as I KNOW, the "Previous track" functions and "Next Track" allow you to scroll through all the separate tracks within a single tracklog.

    I think that the terminology can be kind of confusing.  There is 'tracklogs", which are the GPX or KML files.  Then there's "leads," which are the individual legs of data stored in the tracklogs.  I think that most people probably just record a track by tracklog, but hypothetically, you can record several tracks in a single tracklog.

    So, let's say you are on a shoot outside and you record your GPS tracks.  You thousand hiking, stop the track and then start a new track in the same tracklog.  This would give to ultiamtely you a single 'tracklog' file which contains two separate "tracks".  In this case, orders of "Next Track" and the "track" would let you switch between the two separate tracks in the tracklog.

    In short, my impression is that the "previous track" / "Next Track" only functions to navigate between multiple tracks in a single tracklog.  They don't allow you to scroll your tracklogs.

    I remember messages for a long time on this issue. People are wondering why the "previous track" / "Next Track" commandments were grayed out and wondering if it was a bug.  I don't know if they just misinterpreted these commands as switch between tracklogs instead of titles, or if the duties were actually not work correctly with tracklogs that had several tracks.
