Identify the elements of L1 backup and restore the last control file

DB version: 11.2
Platform: Solaris 11

We went to a database of development last month. But we kept backups rman Level0 and Level1 more archive logs generated after the last L1.
Our N0 and N1 were planned with an interval of 4 days.

The dev team now wants this DB restore in another machine. In a catalog schema, we did not keep the rman metadata. All we have is the backup pieces.
stcdev_p4lor85q_1_1.bkp
stcdev_yls3gkjl_3_7.bkp
stcdev_mhfr8293_5_4.bkp
stcdev_ipxsr8293_5_4.bkp
.
.
.
I don't know which of the backup are those who is from L0 and L1. If I managed to restore the last file to control the last backup of L1, then things will be easy. What happens if I am wrong to restore the old file of control of L0, which has no info on any new datafiles/tempfiles that I added after than L0.

You guys, how such situations?

After you restore the controlfile, simply ALTER DATABASE MOUNT, and delivers then a BACKUP of the LIST. The list will show you what knows the controlfile-if it shows the L0 and L1 of backups, you can use it. If it shows only the L0 backup, try to restore the 'other' controlfile.
If you can see the timestamps of the backuppieces, which could help identify who's the backup "later."

  • Document the backup and restoration

    Is there some general best practices when it comes to document how your process to backup/restore your oracle databases?

    I'm always afraid that if only an admin understand how backup/restore procedures works for critical business systems, if they left the organization that someone fill their shoes may be hard to understand the process and then if a restore is necessary may not able to complete the restoration.

    But being not not a DBA myself, what kind of details should they document. What kind of details you document in your organizations?

    Also, how many times do you check by database restorations?

    Your fears are justified. One of the risk factors more important that an org has is when these key knowledge has not been documented, were reported badly or only exists in the mind of one or several persons.

    Here is a presentation of the excellent white paper of the Oracle world that covers this exact topic

    Oracle Database Backup and restore
    Best practices and new features
    http://www.Oracle.com/technetwork/database/features/availability/311394-132335.PDF

    This presentation includes an overview of the backup/restore of the issues and possible solutions, as well as a case study.
    You essentially have a similar paper for your own organization.

    Your first steps should be to do what you did in this forum: gather ALL the information and documentation of your peers and the management of it on backup and restore procedures, if any, exist.

    Implying that the step #1 is actually identify (i.e. to make a list of contacts) of the key people in your company with information either in written form or in their own head.

    The most important resource is to start with your own expert.

    Check out the latest collection of any type that have been made recently and collect information about the way they did. It is much more important to begin with better understand how your own org backup/restore, rather than learn best practices. Best practices do you much good in an emergency if your org does not follow them first.

    >
    It depends on the size and complexity of the system, but for the big orgs that I contracted with I usually recommend at least an annual process.

    I also recommend you use any offline storage process include the creation of checksums of the backup files. This ensures that, in case the files are needed, they can be added again check to make sure that there has been no corruption. Too many times the files are archived just without any test and then when they needed it turns out that they are corrupt. If you have never made a backup copy of a CD or DVD and then later discovered it wouldn't work you know what I mean.

    In summary:

    1. start by talking to people keys to the knowledge
    2 document available and stored in a central location
    3. start a mini-project to fill the gaps in the existing literature and knowledge
    4 learn the best practices in the field (what you're asking here)
    5. begin to migrate your orgs practices based on best practices.

    Good luck! We need more people like you who are interested in this topic.

  • I used the backup and restore of the backup C on pc. Then tried to open saved files with IE and started acting weird.

    zip files

    I used the backup and restore of the backup C on pc.  Then tried to open the files saved with IE.  IE went into free fall.  ???

    I have no idea what opened the backup files when you have double-clicked, or if you will not quote you took after doing this...  However, the official way to 'Browse' the content of the backup...

    You can view the contents of your backup by opening the wizard to restore files.

    1. Open backup and restore by clicking on the button start , clicking Control Panel, clicking system and Maintenance and then click Backup and restore.

    2. Do one of the following:

      • To view your files, click Restore my files.

      • To display files all the, click on restore files for all users. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    3. Do one of the following:

      • To browse the contents of the backup, click Browse for files or click Browse for folders.

        When you browse folders, you will not be able to see the files in a folder. To view individual files, use her browse for files option.

      • To search the contents of the backup, click search, type all or part of a file name, and then click search.

    If you back up to the top PC (VHD) integer then you mifght consider this trick:

    According to the edition of Windows Vista that you have (and how useful, you will find the possibility to look at old versions of a given file and possibly restore), this could be useful to you:

    (not a replacement of relief.)

    With regard to the rate of success vs. failure rate of backup - it is difficult to measure.  Indeed most of the people backs up incorrectly.  It's really * not * enough to set a backup and forget about it.  If you test ever that your backups work/glance to see if you are backing up the good thing - it's just not wise.  Although most people expect that it is essential that the backups were working properly (not a test, a real emergency) to be discovered.  Most individuals who report failures, unfortunately, fall into this category "when my aircraft crashed and I went to my backups - it turns out _ backup _ does not and never told me...» ».

    A question... If you manually create a ZIP file (not a backup) - can you still Explorer in it as a folder?

    To test... Create a folder on your desktop.  Copy some files into it - of different types.  I say COPY and not MOVE on the goal here - because you can just blow this folder and all that results from this folder later if it was all fair copies of things.

    Make a right click on this folder and choose "send to" and "compress (ZIP) file and give a name to the new 'folder '.  (It's really a file.)  On your desktop, you should have the original folder you created and copied some stuff in, and a new "folder" with the name you just gave.  If you open the 'new' folder - you should see the name of the folder that is still on the desktop and go to this folder, you should see the files.  You literally use Windows Vista to the 'discovery' inside a ZIP file as if it were a folder.

    MS Internet Explorer on my PC gave me wrong yesterday. It would not start.  After several failed attempts, I followed the instructions to remove the update of IE 9.

    I decided to backup per 24 hours.  Since them my PC goes through a cycle off, restart and informing me that it configures updates with State 0% who never changes, after about 3 minutes, it stops and starts the process of starting again.  When the backup process started, I learned that I can't cancel it.  As restarting the round has now worked for 15 hours, what can I do to cancel it?

  • Why can I not see the files I back up by using the backup and restore of Vista

    Can someone help me?  I have a Dell Inspiron 1525 and implemented backup and restore feature Vista so that every Sunday he automatically backs up my computer to my external drive.  I was on the computer when he said it starts up and that upward was completed successfully.  I assummed everything was fine until today when I show my father my drive external and noticed that none of the backup of files were there... or at least I did not see them.  The only files on the disk were the ones I put manually on here from my old computer.  I then ran a manual upward using Vista and again it says backup successfully completed.  I then watched the external hard drive and once again no new files.  The strange thing is the back up and restore program shows all the dates he has saved and also allows me to restore files from the back to the top.  To do this, I deleted a file I didn't really need out of my hard drive and then is gone to restore program and found the file and restored.  Problem is that the program does not say where he makes the file from.  What is going on?  Are backup files of certain types of hidden file I don't see unless I use the backup and restore program under vista?  I am currently running Vista Home Premium on a 32 bit system and the external hard drive I have is a Western Digital My Book Essential Edition.

    Windows backup is stored in a folder with the same name as your computer.  Open a command prompt and type echo %ComputerName% or startup, right-click on computer, properties.  You should see that % ComputerName % folder on your external drive, and in this context, a backup set.

    Hi ChicagoExPat,

    Make sure that the disks are writable, which means that you can add, remove, or modify the content. If you decide to use this method and have a lot of files to backup, be sure to have enough disks to complete the job. The back up files Wizard you indicates how much space you need whenever you perform a backup and recommends the type of media to use.

    Hi dairy Tech 2000,

    Welcome to the Microsoft answers site.

    Drive/C: would not be shown to the backup files since this is the system drive. You cannot save files to C:/drive to C:/drive.

    However, when you change the backup settings to another drive on the computer, follow the steps below:
    1. click on start.
