With data - loss question mark reversed

Hi people,

Linux - 11.2.0.2.0

When I try to insert special characters (' € @, etc.), it turns out as question mark reversed or some unwanted values.

NLS_CHARACTERSET = WE8MSWIN1252

Please suggest on the same.

Thank you
KSG

Srini,

Yes, the mab issue be with the app/jdbc driver (driver newest is used).

Now suspicious lossy data are perhaps because of the database being upgraded to 11 g, using imp/exp (without csscan).

Exp/imp will not result in data "lossy" condition that the process ran correctly - in fact, it's the recommended way to change charactersets. See http://docs.oracle.com/cd/E11882_01/server.112/e10729/ch11charsetmig.htm#CEGCHGIJ.

Is there a reason exp/imp has been used on the DBUA preferred method for the upgrade?

My web application runs on Java. There is a field "note" in the application, when some NOTE are back extract, it appears with undesirable characters (upside down question mark points, #53 @, etc.). The note field can be typed with any language like french, English and other.

PL specify exactly how you 'see' data - through the app through SQL * Plus, through SQL Developer, or in some other way?

At the end of the database. I create a table and insert special characters. When I retrieve the data through sql, absolutely no problem. The data are very good.

Yet once, pl specify exactly how you 'see' data.

The problem arises when data is inserted at the end of the application.

Thank you
KSG

How the application connects to the database?

    My desktop icons have a blue circle with a white question mark hide them.

    These are icons by programs such as Norton 360 backup and are used to indicate certain conditions such as the status of the backup. You must go into the program generating overlays and disable this setting. In the case of Norton that would be settings in the main window and then uncheck the backup status overlays.

  • Rename a folder with the character question mark (?) in the name of the file?

    The name of the folder in question has a format of "file name? This folder is on my external hard drive and was created when I've used OSX, which had the support of the character question mark (?). However, while trying to access the contents of the folder in Windows, I am welcomed with the error Although the file is inaccessible due to incorrect syntax. Whenever I try to move or rename it, I get the same error of incorrect filename syntax.

    Is it possible to rename this folder so I can access it? Thank you.

    Thanks for your replies. I don't have OSX, so I couldn't go that route. I found myself using Ubuntu to tide me over.

  • Failure of keyboard with apostrophe and question marks, etc.

    apostrophe resembles e.-c question mark e. E, hooks quotes ^ C, etc.

    Usually held on the left ctrl + shift will reset the problem, but this does not work, no more to restart the computer.

    It's a sticky key problem, but can't do it reset.

    It does not resemble a sticky key problem. It seems more likely that your keyboard can be set up for the wrong language. Reach
    Panel-> region and language , then the keyboard & language tab. Now click on theChange keyboards button then the General tab. Verify that the correct default for your keyboard language is set.

  • Partitions of disk utility 2 combined with data loss

    I have a 1.5 TB drive external that I use 1 TB for Time Machine, 480ish Go for some storage media and then I got a score of ~ 20 GB with Yosemite on this. I decided that I is more to Yosemite partition so open THE and got rid of the partition of Yosemite. When it was done the space in the partition was dumped on the storage partition. So far so good.

    Why the media stored on the storage partition is gone? I don't mess with this partition at all, except to add the deleted partition.

    I was hoping to get a clue of what I could do to recover directories for these data. I am relatively sure that I do not erase, but somehow combining both partitions clogged the directory (I think) and the data are, therefore, more "Visual". The data are mainly video I have saved over the years and am not prepared to lose if it can be helped.

    Any contribution is appreciated.

  • Gray boxes with question marks

    When I find some PDF files, a grey box with a red question mark inside appears. I can't move, modify or delete these boxes. I searched on the web and most of the responses indicated that these boxes indicate corrupted images, but my documents have no images. Mine appear at the beginning and end of text blocks. They do not appear in the thumbnail view. I am running Acrobat Professional, version 8.1.

    What are these boxes and how do I get rid of them?

    A screenshot of what I see is attached.

    A little more information, to ensure the excellent diagnostic monitoring.

    When Acrobat opens a PDF file and it finds the annotations of an unknown type it shows these boxes. How have to disappear (or anything else) is to install a plug-in of specific designed to show them.

    Older versions of Acrobat just show nothing at all.

    Acrobat 5 would show nothing.

    Acrobat 7 would show the boxes.

  • Mac mini (late 2012) flashing - question mark folder recovery does not work

    Hi all

    earlier today, I upgraded my Mac mini (end 2012) to the latest version of macOS Sierra.

    After 1 hour of use, I realized that many of my plugins FCPX were not working.

    I contacted the developers, and they said does not update the plugins and they told me to go back to El Capitan.

    I decided to listen to them and try to downgrade my OS.

    I restarted the Mac and held down Cmd - R or something like that that took me to the disk utility screen.

    Then I went down to dinner, and when I returned 30 minutes later my Mac had entered the sleep mode for some reason any.

    I woke up the Mac and 40 seconds later the power went out for 5-10 minutes.

    After the blackout, I restarted my Mac that took me to a black screen with a flashing question mark folder.

    I followed some tutorials online (including how to enter get - and the recovery of internet mode), but after a while even restoration of the internet shows me the flashing question mark folder.

    I don't know what to do.

    And no - unfortunately I don't have a Time Machine backup.

    But I have a backup with all my most important files.

    Is it possible to force the Mac to reset itself or something like that?

    Help, please.

    Best regards

  • Why have I not question marks on my folders in the navigation pane?

    Many of my folders have blue circles with a white question marks.  First of all, what does this mean? Second, how to fix?

    Backup applications set these icons to indicate the current state of the affected folders backup.

    Special symbols you describe sound like the ones Norton.  Go to the Norton support system for an explanation of the meaning of each symbol.  You can disable the symbols if they are of no use to you by changing the settings of Norton [they refer to the symbols as Backup state overlays].

  • Start with blinking question mark folder

    Hey guys, English is not my mother tongue and so I must apologize for my bad English, everything first.

    Okay so here is my question:

    I had a folder of flashing question mark when I rebooted my macbook pro retina (13.3 "end 2015, OS X 10.11.4 beta 6) last week.

    So I get in recovery HD to see if if I can do a clean to fix install, but I can't find my disk to reinstall OS X, he showed is nothing.

    Then I restart my mac again and again, sometimes I can boot normally.

    But I can't found anything wrong, he just worked as usual, until what I restarted again, dead again.

    I took it to the authorized service provider Apple to fix my mac. Yes, there is no official bar of the Apple Store and genius in my country.

    They thought that my drive was dead, so they substitute a new drive for my, it took me a week to get my mac.

    It seemed to work perfectly, so I restore my data by Time machine and upgrade to 10.11.4 beta 7.

    Yesterday the 10.11.4 came out, so I updated my mac to this version.

    But when it is restarted during installation, it showed the issue of question mark again.

    After a few attempt to reboot, it finished installing. then I tried to reboot to see if it's good or not.

    Unfortunately, it came with this folder again. So I turn it off.

    After half an hour, I tried to start it again, it starts.

    Everything seemed normal, I checked the S.M.A.R.T by DriveDx and the data were all good.

    I fix the permission by DiskWarrior and it says no need to repair.

    But I always get the record of question mark with 1/10 chance when it start.

    I don't know what happened to my mac, is there anyone has a suggestion?

    Thank you

  • Blue square with a question mark instead of a picture

    I'm on Messages to use with your Mac - Apple Support.

    Instead of pictures (or), I get a blue square with a question mark in it.

    This does not happen with all Web sites, but I wonder why it's happening with an Apple site, and how I can see the photos.

    It sounds like a broken image link.

    Post a screenshot if you can, so that we can confirm. The page seems OK after a glance. Command + shift + 4 then do slide on the affected area, add the image to the desktop to this site via the camera icon.

    If you have browser extensions, disable them and repeat the test. Also try a different web browser if possible to see if it is the scale of the system or only Safari. Is - this Safari you use?
