How to restore ASM based OCR after complete loss of the CRS diskgroup (Doc

Hello, I'm testing Metalink doc id 1062983.1.
I have rac 11.2.0 with asm on Hp-Ux. I have an CRS diskgroup with external redundancy. The Unix System administrator dropped crs disk:
GRID user:           oradb
GRID home:           /oracle/product/11.2.0/grid ($CRS_HOME)
ASM disk group name for OCR:      CRS
ASM/ASMLIB disk name:      CRS_0000
Linux device name for ASM disk:      /dev/rdisk/disk27
Cluster name:           crs_desa
Nodes:                rx2
I've checked backups
rx2:/oracle/product/11.2.0/grid/cdata/crs_desa $ ls -ltr
total 89384
-rw------- 1 root sys 6537216 Dec 7 20:34 week.ocr
-rw------- 1 root sys 6537216 Dec 8 00:34 day.ocr
-rw------- 1 root sys 6537216 Dec 9 00:35 backup02.ocr

-rw------- 1 root sys 6537216 Dec 9 04:35 backup01.ocr
-rw------- 1 root sys 6537216 Dec 9 08:35 backup00.ocr
But I can't start CRS stack in exclusive mode. I've tried crsctl start crs -excl as root but I've got
rx2:/oracle/product/11.2.0/grid/bin # crsctl start crs -excl
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.
can anyone help me please?
Thanks in advance!

You need to first stop the crs stack on all the nodes and then start the CRS stack on one node in exclusive mode.

    How to restore views and procedures after drop user command?
    We have 817 EE on NT and one developer created a lot of procedures, functions and vews. DB was not backuped and archived and export has not been done - our fault and we understand it. Sorry for this.
    Ok, now the story: another developer dropped this db user and we lost everything: procedures, functions and vews. The new user with trhe same name was created and new schema was imported in this user, but all old objects are lost. We don't have export and backup and archive log files.
    Question: may we can restore this lost stuff from some other sources. We are looking for lost codes, not data. May be we can use redo logs or shared pool or any other things. Any idea will be appreciated.
    Thanks.
    Victor
    [email protected]

    The switch has occurred after user was dropped, the data has been overwritten and there is be no way to use redo log files.
    I would like to explore another opportunity. Is possible to use Shared Pool or any Data Dictionary internal information to restore texts of the lost SQL and PL/SQL scripts executed in this DB before user was dropped? Not too many scripts are executed in this DB and the lost ones may still be in stack. I remember that Shared Pool (cash) should keep last executed scripts in order to improve performance. They probably are kept in some special format. Can we restore these scripts? Of course they also might be pushed out by Import that had been done after user was dropped.
    Thanks for your help,

    Thanks Eric,
    After inserting the original DVD I installed OSX and after reboot I had a working computer.
    There was no opportunity to restore the TM backup. however when I rebooted from the
    DVD again I saw that possibility from a menu of the install utility.
    I ran through the restore over night (8 hours) and when I woke up, I had my computer back!

But Apparently Now Even i Don't Remember The Pass So if Someone Could Please help Me On How To Regain Access of That Locked Documents ? ( Thanks in Advance )

    Once you set a Pages document password, you will need it again to unlock the document. There is no other available unlocking technique, as many before you have discovered. Tell your mind to recall your document password, and then stop trying to remember it. Let your subconscious retrieve it.
    In the future, keep a secure, analog list of your passwords as backup.

  • How much does Premiere Pro and After Effects rely on the hard drive it's installed on?

    This may be a really dumb question, but how much does Premiere Pro and After Effects rely on the hard drive it's installed on if all your video files, assets, disk cache, etc are on different drives than the one the program itself is installed on?
    The reason I am asking is that I currently have a "relatively" slow Sata II SSD for my C drive that has just my OS (windows 7 64bit) and programs (adobe editing programs, no games) installed on it and nothing else. All of the files used in my projects are saved on either a very fast Sata III SSD or a slower HDD depending on what the files are. For example, disk cache on the Sata III, stills on the HDD.
    Being cyber monday I have the opportunity to buy another very fast Sata III SSD to replace my current Sata II SSD C Drive (just OS and programs). Both synthetic and real world benchmarks show a near double in performance. I just want to know if anyone thinks the upgrade is even worth it because for all I know there won't be any increase in performance since no videos, still, cach, etc will be stored on the C Drive.
    The alternative is to get a second monitor because I currently only use one 21" monitor.
    I suppose another alternative would be to not buy anything on the cyber monday deals and just save money for something else.
    Any advice or input would be greatly appreciated. Thanks!

    Thanks Alex! I think you are right about not being able to notice the difference between the SSDs. I ended up finding a deal to get about $80 off a great monitor that I've been looking at for a while and decided to pull the trigger on it. I thought about it and realized that there have already been a bunch of times where I want to watch a tutorial on youtube and follow allong in AE or PrePro, but have to keep switching windows. I also frequently want to have my video preview on a separate monitor so I can have a taller timeline window. This monitor will help a lot with that. Thanks again for your help!

  • I am not able to restore my iphone 4 after trying to install the new softwear. I tried every single possible way. What can I do?

    I am not able to restore my iphone 4 after trying to install the new softwear. I tried every single possible way. What can I do?

    There are two ways that a backup can become encrypted:
    You chose to encrypt it, then forgot the password.
    If you have company-provided MS Exchange access your IT department has the option of requiring your backup to be encrypted. The first time you backed up or synced after installing MS Exchange you were prompted for a password. That is the password you need.
    If you don't have the password any longer there is no way to restore the backup.

    Thanks for this response. After I posted mine, I saw that the resetForm JavaScript method is documented as being supported starting with version 10.5: http://www.adobe.com/devnet-docs/acrobatetk/tools/Mobile/js.html
    But I haven't been able to get it to work. Can you clarify if support was indeed added and if it works for you?

    You would only have that backup if you saved it somewhere.
    Itunes only keeps the latest one.

  • How to restore Mail and iphoto after a complete OS reinstall

    Hi
    I have searched as best I can to see if anyone has asked the same question, but no luck.
    I want to do a complete reinstall of Leopard. I have an external HD and have activated TM so as far as I know I have a full back up.
    Once I reloaded the OS can i bring back my Mail set up as it is. By this I mean, is there a way to restore all my folders, emails and settings?
    Also with iphoto, can i bring it all back in as it is now?
    I fully understand how to get a file back using TM, it seems pretty easy, but applications seem a little more difficult.
    Please can someone give me some advice on this.
    Many many thanks
    Stewart

    So you intend to erase (or replace) your boot disk and install Leopard on it, right? After the installation finishes, you'll be asked to create your account etc etc etc. The very last step is you are asked if you'd like to use the Migration Assistant to restore from another Mac or TimeMachine. If you say yes the Migration Assistant starts up and you can choose your TimeMachine drive.
    Here I'm fuzzy because I've not performed this step. I think you'll get the same options as you do if you migrate from another Mac - the choice of Applications, Files/Folder, or Library. If I'm correct, you choose what you want to migrate, start it, and walk away until it finishes.
    Now I know this works because I did before I knew I could use the Migration Assistant with TimeMachine. After you get to the desktop you select TimeMachine and select the drive that has the backup. TimeMachine starts up and you can browse the folders and times until you find a folder/file you want to transfer. Select it, click on the Restore button down at the bottom right hand corner of the screen, and let it work.

  • How to restore ipod Touch 4g after failed Jailbreak!?

    I was using Redsn0w to Jailbreak my iPod today, everything was going well, until the running codes appeared. it was stuck there for 2 minutes then, my iTouch went completely off, redsn0w detected my ipod even though it would not turn on. so I pressed the Recovery Fix button and nothing happened. I disconnected my ipod, and reconnected it and went to Itunes, I held the power and home button for 10 seconds and then after that I held the home button only for 8 seconds. itunes then asked me if I wanted to restore my ipod, about 2 minutes later it came up with an error saying that it could not restore my ipod. Could anyone help me? I really need to fix it before i get it repaired by someone else and have to pay a bunch of money.

    Sorry, you will have to use Google to search for a solution. We can not assist with hacked devices on Apple's support site.

  • How to restore using increment backup after full backup restore in RMAN?

    Hi All,
    We have a files of full backup of database after turning on the Archive log.
    And after that, daily incremental backup is taken.
    Now, i want to restore the the database into a new machine using both files of full and incremental backups. Can anybody give me script for restore of full backup and after that restore of incremental backup?
    Thanks,
    Praveen.

    Praveen,
    >>
    In my case, i have 2 sets of backups. One is full backup and other is incremental backup. In order to keep the restored database upto date, i need to restore the full backup and then restore incremental backup. Now, i got any idea how to restore using full backup. My doubt is how to update the restored database with incremental backup also?
    >>
    Restore always looks for level 0 backup, not the incremental backups.
    Incremental backups comes in picture during recovery.
    During Recovery, Oracle looks for incremental backups, if exists, it will do the recovery with the incremental backups, if no incremental backups available, then, it will look for archived logs.
    Therefore, incremental backups never used during restore, they are used only during the recovery.

  • How to restore playlists and ratings after hard drive format

    Several people have reported problems restoring paylists and ratings after reformating a hard drive. Here is what worked for me and what did not.
    I had to reformat my hard drive. Before doing that I exported my playlists from itunes to another hard drive as an xml file. I also copied the folder with all my songs to another drive. (Also of course had it backed up on DVDs.)Then I copied the itunes library files (see url http://docs.info.apple.com/article.html?artnum=93732) to anoher drive.
    After reformating my hard drive and installing the lastest verion of ITunes, I copied the actual songs back into a subfolder in my music folder. I then told iTunes to import the subfolder with the actual music. That resulted in a restored library that lacked playlists and ratings.
    Don't do this
    I purchased Anapod ($30.00) because its web page said (http://www.redchairsoftware.com/anapod/):
    "Anapod CopyGear is an easy-to-use, compact utility for copying music tracks, playlists, podcasts, photos, and videos from your iPod back to your PC."
    Well, I did transfer 104 playlists back to my iTunes library through the Anapod backup function. However, the transfer also put more than 20 gigs of duplicate songs into the library. All of the songs listed in the playlists were duplicated in iTunes. I could find no way in Anapod to simply copy the ratings and the playlists. Anapod documentation was outdated. For example the online help pages said that playlists could not be backed up. This was confusing because I had just done that.
    "In a future release we will be adding the ability to backup your iPod playlists. This will allow you to generate backup files of your iPod playlists on the computer. These files will not be usable on your computer though. They can only be used to restore playlists at a later time on your iPod (assuming it still carries all the audio files referred to in that playlist)." This text is from url http://www.redchairsoftware.com/anapod/support/tome/tx2pc.php#5.1.2
    I sent requests to Anapod for help today, but they have not been answered yet. Docs truly did not seem to help. Would have been good if there was a pdf file rather than just an online help html file that seemed outdated.
    This worked for me:
    I ended up having iTunes wipe out the entire library because of all the dups Anapod made. (Made sure that iTunes only wiped out library and did not delete actual songs from hard drive. Then I had iTunes import my subfolder with songs again. That brought me back to where I was before wasting money and much time on Anapod.
    After I had my iTunes library up (without ratings and playlists and after finding Anapod did not meet my needs.
    1. I imported the xml file to which I had exported playlists before reformating hard drive. That gave me the playlists back although an error message said some items not copied because the music tracks listed in playlists were not in my iTunes library. --Possibly I deleted songs after playlists were downloaded some time ago to iPod. Importing the xml file is probably not necessary because of what I did below.
    2. Quit iTunes
    3. Because my song ratings were still missing, I then moved the iTunes library files made by the new version of iTunes into a different folder.
    4. Then I put my old version 4 library files into the place where the library files should be.
    5. Then I crossed my fingers and restarted iTunes. It took awhile to start and said it was updating my library files. Now I have back most or all of my playlists and ratings.
    If problems develop, I will probably wipe out iTunes library and use Anapod to move everything from my iPod into a folder and tell iTunes to import that folder. That approach might avoid the dups that Anapod makes when restoring playlists to iTunes.
    So my message is keep your actual songs backed up somewhere (such as DVD's and anotehr hard drive) and keep a duplicate copy of your library files somewhere not on your hard drive. With these items you should be able to restore iTunes library to its former status.
    Sorry for the length of this message. Hope it helps someone.

    The simple version of above:
    iTunes Files to Backup (anytime you make additions or changes to the Music or Library that you want to retain)
    1) All music files in their current folder structure (usually located in and under the ‘iTunes Music’ folder)
    2) The Library database file: ‘iTunes Library.itl’ located in the ‘iTunes’ folder
    3) The Library XML file: ‘iTunes Music Library.xml’ located in the ‘iTunes’ folder
    4) Any XML playlist files created for Playlist retention
    5) The two iTunes.pref files (optional)
    -- C:\Documents and Settings\<your username>\Application Data\Apple Computer\iTunes\iTunes.pref
    -- C:\Documents and Settings\<your username>\Local Settings\Application Data\Apple Computer Inc\iTunes.pref
    6) The XML file of Ratings, Play Counts and Last Played attributes saved from the main Library and created by Otto’s SaveRatings script (also optional, but recommended):
    “Download this: http://ottodestruct.com/itunes/SaveRatings.zip . It's a program, just run it like any other program. Run it on the machine where you're copying the info from BEFORE you move the files to the new machine. Click the "Save Ratings" button and it'll create a ratings.xml file. Now when you move the files, move the program and this file as well. Then after you make your new iTunes library, run it again and click the "Restore Ratings" button. Voila, all your information is back in the Library. Well, most of it anyway, it's not perfect. It'll tell you what songs it couldn't figure out though, and there's usually not very many.”

  • How to restore old prefs, etc after clean reinstall of 10.3.9?

    Due to a fiasco with Drive Genius I was forced to reformat and reinstall 10.3.9. Luckly, I was bright enough to manually copy over the entire contents of the drive to a firewire drive before I started the drive genius project.
    I was able to find directions on how to restore my users which worked perfectly.
    I've copied all the apps back. But all the apps were in the main drive rather than in users, so the prefs, registrations etc are, I assume, stored in the old library.
    Is there a way to replace the new library with the original to avoid several days work digging out the original packaging to get the serial numbers for re-entering so I can get back to work right away?

    The serial #s, etc were in fact in the original main library. I was able to restore the use of all the programs by manually replacing the missing items in each folder in the library. It took over an hour, but I got it all back and saved me from having to rummage through storage boxes for the original documentation to retrieve and re-enter all the info.
