Recovering lost data from a table

Hi experts,
We have lost some information from EQUI table because of a programming error of a developer, when deleting by mistake some registers with the work area. Is there any way to recover this information without recovering the last security copy??
Maybe from some modification log or something. "log data changes" checkbox is not checked on se11 technical options.
Thank you very much!
Artur

Hi,
reviewers pointed alread to a db backup and restore of the table in question.
Depends much on what DB vendor and version you have.
if you running on Oracle it maybe possible to SELECT on the table with the TIMESTAMP option.
i.e. you want to have the values 5 minutes ago before someone changed and commited
the change:
select * yourtable as of timestamp sysdate - 5/24/60
where .... " you may have some criteria to filter on the rows in question
But if your data is already out of the UNDO retention time you have to choose the hrad way
of physical restore of the table .

Recovering lost data from a very old backup (disaster recovery)

Hi all,
I am trying to restore and recover data from an old DAT-72 cassette. All I know is the date when the backup was taken, that is back in November 2006. I do not know the DBID or anything else except for the date.
To recover this, I bought an internal SCSI HP c7438a DAT-72 tape drive on eBay and installed it on a machine running Windows 2003 Server SP2. I made a fresh Oracle 11g Enterprise Edition installation. HP tape drivers have been installed and Windows sees the tape drive without problem. To act as a Media Manager, I have installed Oracle Secure Backup. Oracle Secure Backup sees the HP tape drive without problems as well.
I have to admit my information about Oracle is not very in-depth. I read quite a lot of documents, but the more I read the more confused I become. The closest thing I can find to my situation is the following guide about disaster recovery:
http://download.oracle.com/docs/cd/B10500_01/server.920/a96566/rcmrecov.htm#1007948
I tried the suggestions in this document without success (details below).
My questions are:
1. Is it possible to retrieve data without knowing the DBID?
2. If not, is it possible to figure out the DBID from the tape? I tried to use dd in cygwin, also booted with Knoppix/Debian and Ubuntu CDs to dump the contents of the tape with dd but all of them failed to see the tape device. If there is any way to dump the raw contents of the tape on Windows, I would also welcome input.
3. Is there any way at all to recover this data from the tape given all the unknowns?
Thanks very much in advance,

Hi 845725,
If the backups were created with OSB might be you can query the tape with obtool.
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14236/obref_oba.htmTo list pieces you could use <lspiece> within obtool.
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14236/obref_oba.htm#BHBBIFFEIf this works you should be able to identify the controlfile autobackup if it has the standard naming < c-dbid-date-xx > and you than know the DBID or you are able to restore a controlfile from a backup piece in the output list.
Might be you have to install 9i or 10g rdbms software as 11g was released a year later in 2007.
Anyway goodluck.
Regards,
Tycho

Can I recover lost data from my calendar?

I have an iPhone 4S and had been using the calendar. When I recently purchased an iPad2 Wi-Fi, i lost years worth of data from my calendar when I attempted to sync the two using iCloud. The data is not on either the iPhone or iPad and I'm wondering if there is any way I can recover this?

Check iTunes via sync to see if you have a previous backup of your iPhone that you know contained the calendar data. You can restore your iPad from an iPhone backup. Just do it in iTunes on your computer.

Can i recover lost data from encrypted drive by Bitlocker

Hello Dears. I had encrypted my drive by Bitlocker in windows 7.
few days after my friend did quick format in my encrypted drive.
my 300 gb of data lost. and nothing saved
i remember unlock password.
how can i recover my data ??? i need my data
i tried drive recovering tools (advanced EFS data recovery, easeus . . ,) . but . . . it's encrypted and formatted drive.
can i undo quick format and decrypt ???
sorry my english is not good.
someone help me please.

BitLocker is not the cause of failed to recover files.
Format a drive will clear all data saved on the hard disk. Thus recovery formatted data will be a hard disk based technology but not related to operation system. There is no build-in data recovery feature in Windows operations. So we will needto use third party recovery tool or contact third party data recovery company for current issue.
As recovery missing data service will be expensive, we can also check emails and contact friends to see if that can help get a part of files back especially for photos, documents etc.

How to recover lost data from a mac that was erased and locked using findmyiphone app

Hi,
My macbook pro was locked and erased using find my iphone app then it was recovered. I entered my pin and unlocked it. I then have the option to reinstall the OS on a new hard drive or my old one (which is blocked).
What do I do if i want to recover all of my old data?

Alas the answer is : NO
If you have an external HD, you may try tun run a recovery tool instlled on this external device searching for keystring "index.xml"
With a bit of luck, it will retrieve an old copy of your document.
I hope that this time you will understand that working the way you did is playing with matches.
Whe you work on a document already saved once, duplicate the document before opening it and check that both copies are OK.
This way you will have at least a copy containg the datas from the 25 first day.
During the working session, don't save with the name of the opened doc, save vert ten minutes with different names.
Doing that you will recover at least the copy which you opened.

Is it possible to recover lost data from an iPhone 4 iOS 5

Hello, I recently upgraded my iphone from iOS 4.2 to 5.0, and in the process of restoring my iphone, my photos and some other settings (some email accounts and phone number "favorites") were not restored. I'm very upset about the pictures....I've lost about 7 months worth.
Before I performed the upgrade, I backed up my iphone, however it appears that the backup did not backup my pictures, as I used some third party software to see if there were pics in the back-up which there was not.
I don't sync my pics with iphoto, because I have previously restored my camera roll from a backup several times in the past, with no issues. What are my options to find all these lost pics?
PS - I use a Mac to sync (but I also have a PC).
1) Is there a way to go back to older version of my back-up file? Like from a couple days ago? It looks like itunes only stores a couple backup files. Do you think I could find older/deleted/overwritten versions with file recovery software?
2) Is there any file recovery software that can look on the iphone's hard disk for these "deleted" picture files? In the past, I've used file rescue software on an SD card to retrieve deleted pics, and it works flawlessly.
Any help is appreciated!!

MCPaulyB,
Have you found a solution to your problem? I, too, lost files during the upgrade to iOS 5.0. My files in Pages, Numbers and Keynote disappeared although the update said they'll be saved in iCloud. They simply vanished after the update.

Can I recover lost data from my hard disk?

I went to Software Update and downloaded all necessary files. When I finished the message said that it couldn't load the Java update. I restarted the computer, the apple showed in the middle of the screen and then it went to a circle with a bar through it, a bit like a no smoking sign. I restarted again but still nothing. I sent it off to the computer tech and he reloaded the original disks but all my photos and documents are gone. Can something be done to recover the files? Nothing shows up in Finder..

Hi,
*"I sent it off to the computer tech and he reloaded the original disks but all my photos and documents are gone."*
If the tech erased and reinstalled the Mac OS X, then those files are gone. But if an Archive and Install was done, then there should be a "Previous System folder" and your files might be there but no guarantees. *You need to contact the repair tech and find out exactly what was done*.
From now on, back your files up so you can avoid this happening in the future.

Can I Recover Overwritten Data from Treo 650?

I synced my TREO 650 to my Macbook. It seems like the macbook overwrote all of the Contacts and Calendar entries on my Treo. In other words, it synced the mac to my treo, instead of the other way around, which is what I need.
Is there anyway to recover the lost data on my Treo?
Thanks

How to recover missing data from PCL4 cluster

Hello experts,
Is there any way to recover missing data from PCL4 cluster ?
We recently found that some data related to W2 production run for past years was missing in the PCL4 cluster. Tables T5UXX & T5UXY has entries with the filing dates but certain data is missing in the cluster related to those table entries.
Would there be any specific reason for such a data loss ?
Has anyone come across this issue earlier and found resolution on the same ?
Any feedback is appreciated.
Thanks,
Dipesh.

When you delete PCL4 entries for production runs, the corresponding
control information in tables T5UXX and T5UXY also will be deleted. A
control number may be used for more than one Form number (in Tax
Reporter control tables). Therefore, if a control number that is
assigned to the Form number to be deleted was also assigned to other
form numbers, then this control number information from T5UXY will not
be deleted. These details will be displayed in the program results.
However, if all Form numbers that were assigned to this particular
control number were deleted, then the control information in table T5UXY
for the control number will be deleted automatically as the last
dependent Form number is deleted."
Following we have two questions:
o Was PCL4 deleted?
o Did the W2 generate without errors?
Basically if the PCL4 data is corrupted, then we have 2 options to
rebuild the PCL4 Cluster:
1. Delete the existing PCL4 & rerun the production run with the same
   As of date.
2. Overwrite the production results without deleting PCL4 data but with
   different As of Date.
If the Employee data is not changed after your
actual production run then overwriting the results will not cause any
difference in the PCL4 data.
Secondly, if you dont want PDF spools or magmedia layouts to be
generated during overwriting of production run, then kindly uncheck
the following on the PU19 screen, so that only PCL4 data is rebuild :
1. Uncheck Employee Copy
2. Uncheck Authority Copy
3. Uncheck Magnetic table"

Adding Data From One Table to Another

Now, this doesn't strike me as a particularly complex problem, but I've either strayed outside the domain of Numbers or I'm just not looking at the problem from the right angle. In any case, I'm sure you guys can offer some insight.
What I'm trying to do is, essentially, move data from one table to another. One table is a calendar, a simple two column 'date/task to be completed' affair, the other is a schedule of jogging workouts, i.e, times, distances. Basically, I'm trying to create a formula that copies data from the second table onto the first but only for odd days of the week, excepting Sundays (and assuming Monday as the start of the week). Now, this isn't the hard part, I can do that. The problem comes when I replicate the formula down the calendar. Even on the days when the 'if' statement identifies it as an 'even day', the cell reference to the appropriate workout on the second table is incremented, so when it comes to the next 'odd day', it has skipped a workout.
I can't seem to see any way of getting it to specifically copy the NEXT line in the second table, and not the corresponding line.
This began as a distraction to try and organise my running so I could see at a glance what I had to do that day and track my progress, but now it's turned into an obsession. SURELY there's a solution?
Cheers.

Hi Sealatron,
Welcome to Apple Discussions and the Numbers '09 forum.
Several possible ways to move the data occur to me, but the devil's in the details of how the data is currently arranged.
Is it
• a list of three workouts, one for each of Monday, Wednesday and Friday, then the same three repeated the following week?
• an open-ended list that does not repeat?
• something else?
Regards,
Barry

It would appear that you external table definition and the external data file data do not match up. Post a few input records so someone can duplicate the problem and determine the fix.
