Blocks recovery

Hello

Only a few blocks in a data file are damaged, can we just pick up these blocks if we use RMAN...


Thanks and greetings...

Only a few blocks in a data file are damaged, can we just pick up these blocks if we use RMAN...

Yes,
first find out what files are damaged.

RMAN > datafile blockrecover block ;

This see below manual too

  • RMAN block recovery

    Hello

    I have an Oracle 11 g R2 server and the journal of alerts reported the following

    ORA-01578: ORACLE data block corrupted (file # xx, block # xxx)


    Yes, I didRMAN> validate check logical database;

    And after that on checkingV$ database_block_corruption I found 3 block are corrupt, all 3 are indexes of the index table_space segment_type.


    Please let me know what would be the best way to recover the corrupt blocks

    Will,RMAN> recover corruption list;  repair the block corruption



    Another concern is that the backup of the database doesn't do 'check logical' before doing the backup. Does it mean that the recovery from backup might not work ?


    Thanks

    No, you need to do both.

    The first command handles the bad or blocks

  • headers block (block media recovery with rman)

    can someone help me on hwo I can find the header of the table,... is block - it possible that segment name is different in the name of the table?

    While I was able to retrieve the blocks with RMAN; My concern is now the long term effects and what is the cause? Also, trying to find a more permanent solution and not to block recovery every 2 weeks.

    Advisor? What should I look for?

    Thank you

    If it is Windows 2008 chances are that you have probably not ASM. Good luck to pick up a few Oracle then

    I would certainly come from SAs for some assistance, they should be able to spot something at a lower level / side storage, have an audit of the PDF file & run the dbv and validate.

  • HP Z620: Jumpers on the motherboard Z620 FMB-1102

    I'm very curious to learn what is the jumper between the PCIe slots on a card mother FMB-1102 don't. I've searched high and low, but can't seem to find a refernce to it in any documentation. The dilemma is that my Hauppauge TV tuner card is not recognized in the Gen3 slots, but it is in the Gen2 ones. I have the BIOS current (3.88) and has been inspecting my boaerd when I noticed this jumper. Wanted to know its function. Thought that maybe he defined the parameters of cardslot somehow. Any help?

    See you soon,.

    Pete

    pete914, Z620 rider is you ask the subject located between the connector PCI-32 white and black PCIe connector above it?  It's the jumper highlighted in yellow in the picture below?

    If so, it is the header of E15 boot block recovery.  There is a jumper on pins 2 and 3 (pins beside your right hand in this picture).

    Move the jumper to pins 2-3 (default) to 1-2 manufally forces the system into recovery for the boot block mode.  The system is trying to reflash the BIOS OF THE system, a player connected USB will boot the system with the jumper on pins 1-2.  It will appear as no system startup and there will be a few flashes of keyboard and maybe some screen guests (it has been a long time since I tried this).

    If the system ROM BIOS is corrupted, the system will automatically for the boot block recovery mode.  It can be forced into this mode by moving the jumper and then reboot the system.  If your computer starts normally, do not move this jumper.  Leave it alone.

    Does that answer your question?

  • HP Z620 workstation: HP Z620 Workstation - WS displays video &amp; Fans Spin loudly or fails - red light with 8 beeps

    Hello

    I have a HP Z620 workstation.

    My processor is an Intel Xeon E5-2660 SR0KK 2.2 GHZ 20 MB 8 GT/s LGA 2011 8 - Core CPU.  More correctly, it's a category of Xeon E5-26xx (dual processor), 8 cores, frequency 2.2 GHz, turbo 5/5/6/6/7/7/8/8, 8 × 256 KB L3 cache 20 MB L2 cache, 95 W TDP, Socket LGA 2011, i/o bus 2 × 8.0 GT/s QPI, × 4 memory DDR3-1600, release date 6 March 2012, CM8062107184801 part number.  This is version 1, not version 2, which is good because the card in my system startup block date 20/12/2011.

    I am using Kingston ValueRAM 16 GB Kit (2x8GB) DDR3 1333 MHz DIMM Desktop Server Memory.   (J'ai également essayer écarter un problème de mémoire utilisé FUREUR de Kingston HyperX 8 GB Kit (2x4Go) 1333 MHz DDR3 CL9 DIMM - black (HX313C9FBK2/8)) as well as herself, to see if that makes a difference.)

    I don't know how to identify my system board other than the one she reads only numbers as "FMB-1102" and "PBLNV0GCY4N0TF" and "such as #618264-001 REV 0 G'.  He has "hp (copyright symbol) 2012 ' and"E93839"and"FXN1"written on it as well.  (After some searching I guess it's card mother 618264-001.  Which differ a card system like 619559-001 - a model later?)

    My graphics card is a XFX R7 240 780 MHz 4 GB DDR3 HDMI DVI VGA graphics card.  (I also try out a video card problem used an EVGA Nvidia GeForce GT 620 1 GB DDR3 SDRAM PCI Express 2.0 x 16 video card to see if it would make a difference.)

    Regarding the power supply, the power supply standard HP Z620 computer PC 800W Power Supply S10-800P1A 623194-002 717019-001.  (I have more than one and who have tried also.)

    With respect to the hard drive, I have formatted and reused a WD Blue 500 GB Desktop hard drive - 7200 RPM SATA 6 Gb / s, 16 MB Cache 3.5 inches - WD5000AAKX.

    My problem:

    1 regardless of what video card I use, if I use the FURY of Kingston HyperX 8 GB Kit (2x4gb) 1333 MHz DDR3 CL9 DIMM - black (HX313C9FBK2/8) memory and starts, I get a blue light, no beeps, no code of message I can say.  However, no tension of the video card (fans not spin) and no power is supplied to the drive hard (do not load and run).  I get a blank screen and can see nothing.  Back fans begin to turn in very strong and turbo mode.

    2 regardless of what video card I use, if I use the Kingston ValueRAM 16 GB Kit (2x8GB) DDR3 1333 MHz DIMM Desktop Memory Server, I get a red light and eight beeps which means a kind of ROM BIOS/CMOS-problem problem problem.  To this end, I tried pressing the button Clear CMOS without result.  I removed the CMOS battery for a sufficient period of time and again.  Nothing changes this situation.  It only happens when I put this special memory in the computer.  If I stick a USB Thumb Drive with file BIOS (BIN) in it which is 3. XX or higher, it will boot to the BIOS on a limited basis.  I also had to understand that I couldn't do anything with a USB keyboard, I could only select options using a PS/2 keyboard - maybe it crashes on some USB devices at this point?

    3. I understand that if I let the rider of recovery from crisis on the 2nd and 3rd pins rather than pins 1 and 2, that it will load from a backup and I can actually do things.   On this basis, I was able to install Windows 10 education 64-bit and a host of programs and otherwise, use the computer normally.  But I can't start unless I have keep that crisis rider of recovery set to pins 2 and 3 and so he can start in the operating system normally by pressing F1.

    4. I while on Windows, updated the BIOS to the latest version, HP Z420/Z620 Workstations system BIOS 3.90 Rev.A (August 8, 2016) using sp77058.exe (19 MB).  I've also updated other drivers as I could with the HP SoftPaq Download Manager (SDM).  None of this changes the problem at initial boot upward.  At the start he complains front chassis fan does not turn, but this is not a problem I have printing allows to stop a boot to the top, it would give just a warning and still boot normally.

    Well my computer works and does that as long as I keep this crisis recovery jumper on.  But I feel that I should be able to solve the problem and he can begin without interference and without resorting to a measure as drastic.  Suggestions anyone?

    Thanks in advance for your time.

    MR. J.

    Juggerknight,

    Keep the rider of recovery of block starting on pins 2 and 3 of E15.  It's 'off' because the 3 pin is not connected.  Put the jumper to pins 2 to 3 "parks" the rider.  Put the jumper on pins 1-2 active boot block recovery mode, and the system does not start with the jumper in this position 'on '.  (You have already discovered this)

    In addition, do not mix unbuffered and registered in the same system memory.  Use either one or the other.

  • Satellite P205D-4378 crashed so that the BIOS update

    Hello everyone,

    It is my first post on the forum, although I've read here a lot.

    My problem seems to be classic: had several problems with my Satellite P205D-4378 crash.
    Visited the Web from Toshiba site, they have a BIOS update that fixes the problems that I have. I do the update, CRAAAASH!, dead computer.

    Death seriously.

    Turn on the other computer, search, find a few websites on "crisis recovery disk Phoenix.

    I read religiously, run to the store, buy a FDD, some readers, usb, the Bios file download, rename, make the drive...

    Trembling with anxiety, I press FN + b, switch on the machine, and it works!

    Well well... at least the works of the Zombie fashion: pink LED, high speed fans, manages the USB FDD, begins the USB FDD, he read for a good two minutes! Then nothing.

    'It's ok, it'll be ok' I think. The starting block is a program that is not more than 4 k, the computer has no bios, impossible to use anything, and must digest a 1000 k bios.

    I wait, nothing happens.

    SO what now? I tried the 'start FDD' ten times at least. Last try, I waited all night! I Went sleep after the computer read the floppy).

    Whatever I do, once the disk has been read, nothing happens.

    I turn it off, I unplug it, I try with battery, no battery, I speak well, I insult, I pray, I cry, I swear... NOTHING WORKS!

    I do something wrong, somewhere.

    On my drive are the phlash16.exe, the minidos.sys and the bios.wph (extract from a file named AASA40. ROM, downloaded with the pack zip on the toshiba site)

    What should I do? I read it on some forums that computer makers like Dell and Compaq deliberately disable the Boot Block Flash, is the same thing with Toshiba?

    The latest version of the bios that I have downloaded is corrupted?

    Is it possible that my motherboard is physically by the update failed? In this case, is it easy to replace yourself?

    I don't want to be ripped off by Toshiba for repair, if the only thing that I miss so far is a combination of keys at the end of the flash Boot Block recovery...

    In short, I'm lost.

    No idea to this wonderful group of reflection?

    Thank you

    Baaharb.

    I think that the update of the BIOS based on windows is security more like an update of the traditional Bios.
    Why? Because using the traditional BIOS there is always a risk that the wrong BIOS would be used.
    The BIOS using focused on victory, this risk does not exist.

    I know a lot of people who uses a bad BIOS and damaged module BIOS ROM.

    Anyway. To show you, I think that there is one solution as mentioned by delvoie, you will have to contact the local ASP.

    See you soon

  • A55 does not start; power indicator not now

    We have an A55 (8705/J3U) just out of warranty (exp. 1 June) that will not start. Feeding tests as good all around (Antec tester), confirming the green power LED 115V on the back. Fans and HD light and service HD LED lights up green in the face, but the front works indicator LED will glow. No beeps for diagnosis, without video to see the POST messages and no set rotation of CD/DVD to try to start like that.  Have replaced the range cables for power, electric, front power switch & led and HD set.

    After reviewing other threads, I see that "[i] f the power button is pressed and the light does not illuminate, then boot block recovery will not work."  If the USB and BBR idea floppy drive looks (and in any event it is did nothing for the PC recently that operating system Windows and usual Office patches: no update of the BIOS).  After you verify that the power supply is good, am I now backed up to no way out (1) new card system, or (2) new PC?  (Because the power switch itself will begin the HD & fans, and it taking four seconds will turn the fans and HD market back, I'm not inclined to think that a new power switch will work.)  But I am open to learn... TIA for any help Yes.)

    Motherboard, that's what I would try next also after reading all of the symptoms you mention.  Your food is really good and it seems that the switch works.  There is the possibility that the LEDs on the switch Assembly may be interrupted, but its doubtful.  A dead CPU could also cause the errors you mention, but it is the least likely to fail.

  • Installation of VMware in VMware Player tools

    Hello

    I installed VMware Player v7, created a virtual machine (Windows) and wanted to install the VMware Tools via Player > manage > install VMware Tools... but nothing happens when I click on this option. The following 2 other methods I found in a Ko do not work either:

    • Enter D:\setup.exe where D: is the first CD-ROM drive configured for your virtual computer = > NOK as the virtual drive does not show the VMware tools.
    • Looking for the ISO file in the installation folder = > NOK: there is no ISO file.

    After searching on the forum, I realized that VMware Player doesn't come with VMware tools and workaround I used was to install VMware Workstation without a license on another computer, find the file "windows.iso", copy it to the computer, mount it as a virtual drive and start the client installation.

    The thing I don't understand is the reason for which the option is available in the VMware Player menu if the VMware tools are not? It's very confusing for people new to VMware and only install VMware Player...

    You need not download VMware workstation to get VMware Tools in VMware Player!  VMware Player 7 is working fine on my system and had no problem downloading VMware tools, so maybe it's a problem specific to your environment/system that may block recovery.

    Take a look at my answer: Re: VMware Tools missing in the Installation of VMware Player 7

    I'm not sure that I have read anywhere or have seen me this free list is corrupted after you use the package. And you can see on your own demo he didn't need advertising. So I would say that you have not really do as a confirmed declaration. Also use RMAN to perform block recovery.

    I haven't tested this - but if a block is on a freelist and corrupted then what will happen when you tried to find a block for insertion and your session chosen block corrupted free list? Although we can mark tables as 'skip corrupted' maybe that applies only when you tablescans. Just as we have a "fix index" procedure to run having satisfied damaged table blocks, perhaps we must 'fix freelists' to make sure that none of the freelists points to a block that is now marker for ORA-01578.

    Another possibility is that this procedure recreates freelists and freelist blocks if corruption is in the freelists - by analogy, there is a procedure (in the dbms_space package I think) to recreate the bitmaps of space segment if they beomce incompatible.
