• the recovered data is only a row during rman recovery Camille

  I tried a point in time for recovery in RMAN, but the table I got contains only 1 row which is supposed to be 2 rows.
  
  Here's what I did:
  
  1 create the table
  2 validation;
  3 insert the value 1 in the table
  4 validation;
  5. Insert the value 2 in the table
  6 validation;
  7 remove the table
  8 validation;
  9 get sysdate July 28, 2010 07:01
  10 make a rman recovery and apply the sysdate recovered, but use on July 28, 2010, 07:0 * 0 *: 00
  11. check the table and found that 1 row only recovered.

• Data loss from turnover

  Hello Experts,
  
  I got backup fully on July 21, 2011 09:00 and I took archivelog all backup JULY 21, 17:00 and then the next day I took another backup full July 22, 2011 09:00, now I have confusion about the backup archivelog all is what he still necessary after the full backup taken on July 22, 2011 09:00
  
  We can keep data loss and I want to restore the database up to the last full backup of July 22, 2011 09:00 or assume that I lost my archive backup and archive files too, can we restore database without archivelog backup and files?
  
  Thanks in advance

  If my database created over 1000 files archivelog 6 months before plowing date, so I demanded of all files from archive until today with the full backup?

  Rep. : No, you must all archive logs after your last full backup taken.

  Created DB: January 1, 2011

  Last full RMAN backup: 20 July, 10:00

  Then to recover the database without any loss of data you need for a full backup of 20 July 10:00 + all the Archives of the newspapers after the full backup.

  # Time based recovery

  bootable media;
  restore the database up to the time "TO_DATE (29 October 10 19:00","MM/DD/YY HH24:MI:SS')";
  recover database until time ' TO_DATE (29 October 10 19:00 "," MM/DD/YY HH24:MI:SS') ";
  ALTER database open resetlogs;

  # YVERT database recovery

  bootable media;
  restore the database to the SNA 10000;
  recover the database to the SNA 10000;
  ALTER database open resetlogs;

  # The sequence in function recovery journal

  bootable media;
  restore the database up over 100 1 sequence;

• Need help to avoid data loss on a corrupt and/or failure to hard drive

  I don't know what happened. One minute I'm surfing the web and listening to music on iTunes. Then out of nowhere he had a sudden failure. Changed not long at all, but now when I try to turn on my computer, it starts normally but then shortly after that the chime and the apple logo appear, if a progress indicator yet that I've never seen before today. Until the progress bar is still the size of my little finger nail, the computer turns off just. I started in recovery mode and run disk check and repair utility. Make sure the disc is not far off when he said something like - disc cannot be checked completely. Disk needs to be repaired. So when I click on the repair disk, it works only for maybe a minute before it comes up saying - utility disk can't repair the disk. Upwards from your many possible files, reformat the drive and restore your backed up files. So obviously it's not good. What are my options and can I do to avoid losing data that is not already saved? I have a lot of things that have not been backed up and lose some of them would be pretty damning. That's my main goal; data loss as little as possible. My computer is an iMac 2012 end Mavericks 10.9.5 running.

  Thank you.

  You do not have a current backup? If this is not the case, your only real option may be to pay a data recovery company and see if they can help you. Which can be very expensive.

• Transfer of files between drives: data loss or corruption?

  1. Is there data loss or corruption during the transfer of files between disks in Windows 7?
  2. What about very large files, gigabytes in size?
  3. Is it possible to check if there is data loss or corruption?

  Creation and verification of a checksum is a file operation.  It doesn't matter where the files are stored.

  It doesn't matter if the source is a CD, a USB flash drive or a hard drive.  As much as the destination is concerned, if you write a large file on a CD, the possibility of error is greater if copy to a USB flash drive or an external hard drive.  Which is why you often see tips to burn at the slowest speed available when writing large critical files as an ISO installation file.

  The only difference between 'copy' and 'move' is this movement copies the file and automatically deletes the original.

  You want to make sure that the file copied correctly before the original has disappeared.  The way to ensure that is to perform a copy operation, check the integrity of the copied file and delete the original.

• RMAN recovery catalog number

  Hi all;

  Lem I have a probwhen you configure the recovery catalog.

  SERVER 01: 192.168.1.105 DB - NAME (db1)

  SERVER 02: 192.168.1.106 DB - NAME (db2)

  DB1 the TNS alias name is : DBONE -> 192.168.1.105 

  db2  the TNS alias name is : DBTWO -> 192.168.1.106

  I tried to cash catalog of recovery in db2 to db1. but I encountered some problems.

  Already, I have configured listener, tns entered into two servers.

  The OS level - in db2 database) (192.168.1.106 server) here's the problem ...

  rman catalog username $ / password@tns_aliasname.

  I want to know, TNS ALIAS name should be what server what show above the command?

  Thanks in advance...

  Run rman in your data base (d1) target server (105).  The tns for the catalog alias is dbtwo.

  Connect to 192.168.1.105 'oracle' (or the owner of oracle)

  value your ORACLE_SID db1

  RMAN target / catalog rmn_rc/rmn_rc@dbtwo

• What are the causes of data loss during an update?

  Just what are really the causes of data loss or corruption when you update. Most sites will tell you to back up what I'm doing, but none of them actually appoint a cause to save.

  -Thanks in advance

  Minor updates in an OSX * may * break the file system.  Fully upgrades to other OSX replaces almost all file systems.

  Some backup of people even before you install some software packages, because they know how this package changes directories OSX.

• Producer/consumer vs Master/Slave of data loss

  Hello users of Labview,.

  I did experiment with vs p / M/S lately in the context of data aquistion. Many messages did appear (correct me if I'm wrong) that p/c is the correct architecture to if the data retention is desired, so that's what I tried to implement.

  In the loop of producer, I've included 3 Assistant DAQ VIs (2AO, 1 HAVE), which generates data actively and which is being queued. I have 3 other loops of consumers, two of which are consumer 1) written loops of 2) outputs TDMS data of a chart 3) no producer: structure of the event, monitors changes to the user interface.

  When I run data acquisition, the generated file are always half either acquire the half of the sample that I've specified regardless of the sampling rate. I also have a strange displayed graph (see image).

  However,.

  If I replace with a master/slave architecture, this seems to solve the problem.

  So question is: anyone met with this kind of problems? Are there disadvantages to stick with M/S instead of p/c in terms of data loss?

  Thank you

  johnji wrote:

  I think I'm well done

  You are not.  Once an article is removed, he went.  Since you have three loops made of the same queue, each loop will get ~1/3 of the data.  If all the loops are to treat everything, then you want another line for each loop and meet the producer, write to each queue.  You can also use a user event.

• Recovery partition Vista (WRE) ERROR cannot open C:\RECOVERY. DAT

  Hello

  I have a big red error and "unable to open file C:\RECOVERY. DAT" when I try to start my Windows Vista (Windows Recovery Environment) restore Partition on my old Asus F3E (I can start the Vista operating system without problems, but not the recovery partition).»

  I read this and other messages that suggest to use the F8 key to access the Advanced Boot Options menu and select "repair your computer".

  My problems are:

  * My Vista Business doen't have an option to "Create a system repair disc" and I don't have such a drive.

  * On the Advanced Boot Options 'Repair your computer' is not listed as an option, so I can't access "System Recovery Options", I guess that's not present in my system.

  * bootsect.exe is not present on my system.

  (1) where can I get a "System repair disc" disc (trust)? I have another pc with Windows 7. Is it the same if I create a disc repair system there and I use it with Vista?

  (2) where I can get the bootsect.exe tool? It boasts such a disk or what?

  (3) bootsect/nt60 ALL if applies also in my case, fix the trunk of my Vista recovery environment? What happens if I try bootsect/nt60 D: where D: is the drive letter of the recovery partition which I can come up with tools such as ext2fsd? What happens if I use the option "Startup Repair" if I can get a system repair disc?

  Hello Kuldeep,

  Thanks for posting your question on the Microsoft community.

  We need more information about the issue so that we can help you better.

  What is the exact error message or code when you say, 'mislead the GPT?

  Thank you for details on the issue.

  GUID Partition table (TPG) is a new style of partitioning that is part of the Unified Extensible Firmware Interface (UEFI) specification. This is used for Windows 8 facilities factory for more flexibility of partition and

  more advanced features of Windows 8. With an installation of Windows 7, the GPT partition must be removed and UEFI BIOS must be configured in a configuration to boot Legacy.

  Important notes:
  Converting a hard disk partition or volume from NTFS to FAT32 requires that you reformat the partition, which deletes all the data on this subject. Be sure to back up data that you want to keep before you begin.

  BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.
