Recovery of Recovery Catalog

Hi.
I am going to have to explain to our boss of bosses what I think we should do in order to "optimize" our Oracle databases and how to reach closer to HA.
I will recommend three possible moves:
Dataguard (probable, since its my uunderstanding this in much cheaper and easier to configure than the next point)
RAC
and RMAN
I expect to have to explain more about all of these, but what does concern me is this (actually a worry of a DBA here who wants to stop us using rman for some reason):
ALl information about backups, rman scripts etc, are stored in the REcovery Catalog repository. What are the common measures in backing up the recovery catalog, and what are the dangers when we have to do recovery on it?
I am asking this, since I know the DBA here will tell us "I am concerned with recovery. If production database needs recovery, then we find the recovery catalog is lost, then we will have to do x2 recoveries. With our present system, we just recover from the back up disks"
I dont share his opinions, I just need to know how I can best argue for the cause of RMAN!
Thanks

Yes but isnt that information erased after a default setting?A default setting of what? As stated, the control file is the primary repository of the information rman needs to track backups and effect recovories. Nothing need be erased and I'd think it would take some rather extraordinary measures to 'accidentally' erase the rman info from the control file.
If your senior DBA is resisting the use of rman for backups, he is in some severe need of re-education. Actually, he is in some severe need of attitude readjustment. An attitude of resisting new knowledge, new features, new techniques will not serve his career well.

  • How To Make a Clean Recovery using Recovery disc

    For solving  problems related to recovery from recovery discs you have to follow the steps below.
    You need a windows 7/8 dvd(or by a bootable pendrive with  win7/8),and your windows recovery discs for complete restoration.
    Step1:insert win7/8 dvd and restart your pc.Enter the boot menu and select cd/dvd option to boot from dvd(for bootable pendrive,select that option).
    Step2:After windows have loaded the windows files,click on install win7/8.
    Step3:select custom installation
    Step4:Now you will get a window with your harddisk partions.Click on Advanced option in the bottom of the table showing partition list.
    Step5: Delete all partions for obtaining a single drive.
    Step6:After deleting all partitions,you will get a single partition showing your harddisk size.Click on that drive and then select 'new' from bottom options.
    Step7:Then windows will show a warnig.Click on 'YES'.And dont make any change to partion size and proceed.
    Step8:After doing this you will get a 100mb system reseved memory and rest of your harddisk size as a drive.Then close the installation window.Restart you pc with windows 7/8 recovery disk.And follow the steps for recovery in recovery media.
    Then the installation will complete without any errors.And you can have the OS as per the recovery media have.
    good luck.. 
    If youtry to recover directly it won't work all the time.
    So Kindely do as above

  • During recovery from recovery partition I get message "INF file txtsetup.s​if is corrupt or missing

    During recovery from recovery partition I get message:
    INF file txtsetup.sif is corrupt or missing, status 14.
    Setup cannot continue. Press any key to exit.
    Now I have a computer with a recovery partition and that's about it.
    The C partition has been formatted by recovery and files have been copied but I can't get any further.
    The computer is an nc6220 and the OS, if the recovery would work, is winXP pro.
    Anyone have any ideas ?

    I assume you ran recovery from the hard drive?
    If so,
    I would run a chkdsk on the recovery partition it may fix the sif file corruption.
    You can do this from a XP boot cd using the command prompt, you just need to run it on the recovery partition instead of the C drive as explained in this article.
    http://kb.wisc.edu/helpdesk/page.php?id=5097
    if you use the
    map
    command, it will list all the partitions and the drive letters 
    so the command might look something like this
    chkdsk /r D:
    D: represents the recovery partition, which may be different than D:

  • HP laptop g7-1150us recovery (from recovery media) failed.

    Model: HP laptop g7-1150us
    recovery media: 3 DVDs that I created when I got this laptop.
    Hard disk: I have run diagnosis for hard disk. Passed.
    Problem:
    I have tried recovery from recovery media. Following the instruction, I insert 3 DVDs. It copied the required files from DVD to the hard disk and shows "recovery preparation is complete".  Also, it shows it will start recovery after restarting the computer. Once the computer is restarted, it shows boot failed. It is exactly the same story when I tried recovery manager from internal recovery disk.  

    If you can read the 25 character Microsoft Windows 7 license key attached to bottom of laptop, you can download a Windows 7 ISO file to burn to a DVD or USB flash drive. The version  must match version that came installed on your PC as  listed on the Microsoft COA sticker attached to bottom of laptop. Such as Windows Home Premium.
    Link to the Windows 7 ISO file downloads:
    http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/
    You can use the Windows 7 USB/DVD installation tool to convert the ISO file you download. Link and instructions below. You need a  DVD+R or DVD -R . Or a 4 GB flash drive to use the USB method.
    http://www.microsoftstore.com/store/msusa/html/pbPage.Help_Win7_usbdvd_dwnTool#installation
    Use the 25 character key on the COA to activate the installation.
    The key will activate either a 32 or 64 bit installation.
    Next go to your support and driver page to install the drivers you need.

  • Crash recovery/ instance recovery

    Hi,
    How do oracle identifies crash recovery/ instance recovery
    is required?
    Regards,
    Mathew

    Hi,
    >>But how do oracle identifies dabase is abnormally down and crash recovery is required?
    I think that the checkpoint information that is desynchronized in redo log files and datafiles. It is necessary understand what is a checkpoint and what the CKPT process do. A checkpoint is a moment in time when all the changes (dirty blocks) made in the database buffer cache are made to the data files. The checkpoint is performed by the CKPT process and it creates an entry in the control file to identify the point in the online redo log file from where the instance recovery should begin in case of an instance failure. One of the ways a checkpoint is initiated is by the data block writer (DBWR) process. The DBWR process initiates a checkpoint by writing all modified data blocks in the data buffers (dirty buffers) to the data files. After a checkpoint is performed, all committed transactions are written to the data files. If the instance were to crash at this point, only new transactions that occurred after this checkpoint would need to be applied to the database to enable a complete recovery. Therefore, the checkpoint process determines which transactions from the redo logs need to be applied to the database in the event of a failure and subsequent recovery.
    Cheers

  • Recovery from Recovery Discs failed

    My notebook is an Envy 17t-3200 3d CTO. It originally had Windows 7 (64 bit). I upgraded it to Windows 8 (64-bit) and then using the Windows store I upgraded to Windows 8.1. I loaned my Notebook to someone when I got it back I noticed a lot of programs on it that they had installed. So I decided to use my recovery disks (Windows 7 64-bit) to clean everything off and reload what I wanted. The recovery choices that appear include “system recovery” and “factory reset”. I decided to select the “factory reset” since it would format my Windows drive and then restored the notebook to the factory condition. After loading the five recovery disks I got screen that said the recovery has failed. It saved the information to a CAB file, but this forum doesn't support attachements.

    Hi AirForce9731,
    Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP ENVY 17t-3200 3D Notebook and recovery manager fails to restore. Here is a link to troubleshoot why the recovery manager fails  to restore.
    Please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices.
    Hope this helps.

  • Recovery from recovery discs made with recovery manager on g62

    I got the blue screen of death and had to do a system restore for my hp g62 laptop. Before i restored the computer, the recovery manager launched and had me backup my files. I backed up the system on like 15 discs using hp"s recovery manager. After it was done, i returned the computer back to factory settings. Now, im having a problem using the recovery discs made thru the recovery manager. The files arent being read. I tried to copy them and move them onto the hard drive....and they are all saved as .wim files....which arent read by anything. So i have all my files backed up, but that arent opening. How the hell do i open my files that i backed up? How do i put my files back on the computer?

    Hi,
    I've never really used the HP File Recovery system, but you can open an Image file as follows.
    Download and install 7-Zip from the following link.
    http://www.7-zip.org/
    When installed, right click on the .wim file, select 7-Zip, select Extract Files and click Ok - your files should be in the newly extracted folder.

  • HP Pavilion Dv6 7078CA Recovery without recovery disc

    Hello!! i have an Hp Pavilion Dv6 - 7078ca, and after just 6 months of use, the Hard Drive just died.
    because i live in Brazil, and brought the Computer back home, i couldnt use the warrant, since the warrant is for canada only.
    so i changed by my own the HDD for one on the exact same model that it had, but for my surprise, when i used the recovery media that i had made, the DVDs were corrupted, so i coudnt recover it using the recovery media.
    I tried to install the windows 7 home premium (the same that came with the notebook), but there was some hardware incompatibility, so i couldnt install the drivers of it.
    and the worst problem is: i cant even order other recovery media, because even if i ask them to deliver in some friends house in Canada, so this friend ships for me, HP canadian website dont accept international credit card.
    so, my question is, anyone know if i am able to restore my computer without this recovery medias? if yes, how can i do that?
    thanks!!
    This question was solved.

    I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post ( serial numbers and case details).

  • Windows 8.1 recovery without recovery disc or product key

    Hey!
    I own a HP g6-2207sg. After windows 8.1 upgrade and a new set of AMD drivers windows is not starting anymore.
    Not in safe mode, not with different starting settings. Recovery points are not working, from 3 restore points (2 automatic 1 critical update (win8.1)) none is working. 
    I can neither refresh nor reset windows, nor can windows repair the startup (it fails as well).
    I dont have my win8 product key, as it is not in or on the g6 and i never read it out when the laptop was still working.
    I tried reading it out with the help of several 3rd party tools through command prompt, started from a usb stick, which is not working as there are windows functions missing.
    I cant download a fresh .iso of win 8 from windows itself as i dont have the key.
    Please help, i dont know what to do anymore and i need my computer for work.
    Thanks!

    Hi,
    The Windows 8 Image source does have a download limit in place, but it will usually work if you keep trying for a couple of hours.  The key will be automatically read from the bios during installation.
    I'm not aware of any way you can decipher the encrypted key via the command shell - only from reading its entry from the registry.
    Unfortunayely, as with previous operating systems, neither Microsoft or HP will have any record of this key.
    Another option would be to order a replacement set of Recovery Discs starting on the link below.
    Order HP Recovery Discs.
    If you have any problem with this link, order them directly from HP.
    If you live in the US, contact HP Here.

  • Windows 8.1 notebook , recovery using recovery disc

    my spouse after  spending less than 10 hours in 20 years of having computers in our home thought he had made recovery discs after I purchased his notebook for him.
    It turned out he did not follow the instructions correctly and made only 1 recovery disc.
    Now I have the recovery discs set but some say to press the F10 key and others say the F9 key, which is the correct way to do a recovery, no speakers are attached right now and it is plugged directly into the wall outlet, not even connected to the Internet.
    I purchased it for him with windows 8 pre installed and 8.1 downloaded with the updates, he did a restore but is no longer working correctly, no apps or email,( windows live mail). When he turns it on updates download and then uninstall and then his notebook freezes up, it seems he cannot do a recovery from the partition on his system.
    Would someone please tell me the correct way to do a recovery for my spouse so that I can fix his notebook .As I said he rarely uses any computer not even to check his email, he leaves that for me to do.
    As for me I am more familiar with windows 7 and hate windows 8.

    it is  F9 key. The HP instructions here should be helpful:

    Follow the instructions on this  HP document.
    This is a link to your notebook's web suport portal. The drivers for Grahhics adapter , fingerprint validity sensor and touchpad can be found at the Driver & software download section. Intall the driver that match your operating system and installed hardware. Don't forget to install the HP Support Assistant. It can be quite helpful.
    Kind regards,

  • Lenovo G570 - I delete my recovery partition, recovery DVD doesn't work.

    Hi! 
    First of all - sorry for my english.
    I have problem with my Lenovo G570.
    I make a backup DVD with system by OKR (4DVD). Then by accident i DELETED my recovery partition. When i try to boot from these DVD i get error: "The program cannot restore the system partition because its structure is incorrect ,you may have to recreate the partition to continue".
    My partitions looks like this:
    C: New installation of Windows 7 enterprise trial
    D: Lenovo (default partition with drivers and backup)
    Hidden empty partition where recovery was.
    What should i do now?

    one key recover won't work when you delete the hidden partition. there is only one way to fix this issue that is shipping back to service to reset the hdd its default ( lenovo may charge you )

  • Restoring a Data Backup Made With HP Recovery Manager - Recovery Manager has Since Been Removed

    My system (Pavilion dm4 notebook, Win 7 Home Premium x64)) is working fine but I would like to restore a data backup made with HP Recovery Manager. HP Recovery Manager has since been removed from the system and I do not have a recovery disk. I tried installing sp45415 which supposedly runs a silent installer for Recovery Manager, but it silently fails on my system. The accompanying notes say it is applicable to Windows 7 computers and to Pavilion dm1 and dm3. There is no mention of the dm4. Is there some trick to getting sp45415 to run correctly? Is there somewhere I can download an installation package for HP Recovery Manager that works on the Pavilion dm4? Is there any other tool that can restore the backup made by HP Recovery Manager?  Thanks!

     If you uninstalled Recovery Manager it likely removed the recovery files in the recovery partition.When those files are removed-no download of Recovery Manager is going to install. You will need Recovery Media to boot from to restore the recovery partition and files. If you did not make Recovery Media you will have to order from HP. As for the files you are trying to restore- If this was a backup of personal files,photos,etc to external hard drive or dvds there should be one .exe file inside those files-probably Restore.exe or Recover.exe. Double clicking the .exe will extract the files to a folder on the hard drive of your laptop.
