character set question

Hello

I've migrated an oracle 11g on oracle 10g database. The 11g database has EE8MSWIN1250 character set, the g 10 a WE8MSWIN1252 character set. The Polish letters appear with '? ' character. Is it possible to change the character of 10g of th on EE8MSWIN1250 without re-creating the database?

Radoslaw

Can you change the character set of target database or create new database with correct character set? If you can't, there is not much you can do like 1250 and 1252 are indeed incompatible in some code points (1252 lack some of that is present in 1250 and vice versa). The best thing you could do here is to create a new database with AL32UTF8 as default character - this database accepts virtually all the input data.

  • character set of database for forms

    I'm sorry if this is a stupid question. I plan on upgrading versions 10.1.5 database at 11 GR 2. We are currently using forms 6i and 11.1.1.4.  After the upgrade

    the database, I hope that upgrade of the forms to the more recent version.  Is there a certain character set should I use in the database to accommodate

    form 11.1.1.4 and 6i or can I just use what is the default?

    You must use some characterset is currently in your original 10g database to avoid problems with forms and reports.

    Nordine salvation,

    I suggest you to refer the link: "How do I convert the character set for Oracle R12.1.1 running on 11.0.6 database Oracle US7ASCII' as it is very relevant to you."

    Response to your previous post would be:

    S ' stick to a plan

    -Try all of the activity on the TEST server for yourself

    -Troubleshoot and debug all the question from A - Z

    -On the successful implementation, make a backup of the Production and move the solution to PROD.

    If possible, run a lot of questions while doing the character set migration oracle applications, database because it contains the application tables.

    I accept the fact that EBS database is complicated to a database independent, but still all the features and debugging tools and troubleshooting is the same, although it is autonomous or EBS database.

    We should do if we stuck to the top in with and truncate in the application according to the CSSCAN results tables,.

    little tables when we checked in Metalink he says to avoid these tables which do not affect the database or application.

    Try in a Test Server, the above link helps you on the issue. You can find answer to some tables with loss in metalink if it's a bug, just lift a SRt solve your problem.

    What we must do if we are in important application tables, export and import will help in this issue.

    No, if we have available data with loss, then we cannot use the Import/Export and we will have to use CSALTER instead.

    is this the right method or must contact oracle support for assistance on important application tables.

    YES, I personally recommend you try and paralleling have ongoing Oracle support. So that you will have a guide from A to Z, in the case you're wrong

    Hope this helps

  • build the new database through scripts must understand Spanish character sets.

    Hello gurus,
    I need to some simple tips, a good chance for some quick points for you.
    I've never built a database to understand any different other than the U.S. English character set. I now have to build a database that will be used for characters Spanish-keyboards, etc. But I will use English to install 11g software. I just want to be able to show the Spanish characters in the data for the names of clients.
    I will create the database with scripts that I did to make the standard model for data files, control files, etc..
    Then I import in a dump that I did and that was done with American English character sets.
    The system is 11g (11.2.0.3.0) on Linux Enterprise Server 5.8.
    I thought I'd use the AL32UTF8 character set, but I'm not sure where to use them.
    My original test showed no Spanish characters for names of customers as the "tilda" or "sueano" (excuse my spelling). But in this case I did the exceptional for Spanish, I used only the construction of standard American English (no change in the file init.ora or original database create script).

    How can I adjust my settings file for the initial creation of the database model to be able to understand the Spanish character set and still be able to import my dump error-free file.

    EXAMPLE of a build script:

    CREATE DATABASE mynewdb
    The USER SYS IDENTIFIED BY sys_password
    The USER IDENTIFIED BY system_password SYSTEM
    LOGFILE GROUP 1 ('/ u01/app/oracle/oradata/mynewdb/redo01.log') SIZE in the 100M.
    GROUP 2 ('/ u01/app/oracle/oradata/mynewdb/redo02.log') SIZE in the 100M.
    GROUP 3 ('/ u01/app/oracle/oradata/mynewdb/redo03.log') SIZE 100 M
    MAXLOGFILES 5
    MAXLOGMEMBERS 5
    MAXLOGHISTORY 1
    MAXDATAFILES 100
    CHARACTER SET US7ASCII
    NATIONAL CHARACTER SET AL16UTF16

    If I replace to AL32UTF8 AL16UTF16 NATIONAL CHARACTER SET, will it work to show the Spanish characters?

    Sorry for the long-winded question, any advice will be great.

    Fortunately,
    Shawn

    Hello
    the national character sets is for the column as nvarchar types not for normal varchar data types. So if your dump file contains column types, you also need to set. The character set is for normal column as a varchar types. The use of unicode is best practice if you use the multiel language, but keep in mind that multibyte character set can be a problem when importing because varchar2 (10) means byte 10 and not 10 characters, so mistakes as an identifier for a long time may occur when importing.
    You can create the database.

    See this documentation:
    http://docs.Oracle.com/CD/B28359_01/server.111/b28298/ch2charset.htm

    You can use a like WE8MSWIN1252 character set which covers the Spanish also (like many, I know) and a superset of us7ascii

  • Character set of database and the national character set?

    Hi all

    I'm sorry if the question is stupid.

    why we need a so-called "national character set"?, I think it's important to keep the consistency of the character set, and this thing "national character set" really confuses me.

    in my opinion, if you are in English speaking countries, use ASCII coding such as your database character set, if not, just use you UNICODE, everything should be good, why?

    Thanks in advance.

    For Oracle Database, database character set is for the data types CHAR, VARCHAR2 and national character set to NCHAR, NVARCHAR2, and NCLOB and CLOB. Please read http://download.oracle.com/docs/cd/E11882_01/server.112/e10729/ch6unicode.htm#CACHCAHF.

  • Arabic character set conversion-help need

    We have our main database running in 10 g (Solaris OS) & planning to move these to RAC 11 g.

    One of our old oracle DB (8.0.5) / solaris, which is not used until recently have need upgrade to 10g Rel2.

    I know that supported direct 8.0.6/8.1.7/9i update-> 10 g

    Current DB: 8.0.5 (character set: AR8ISO8859P6)
    Target DB : 10 g Rel 2 (character set: AR8MSWIN1256)


    I think to go in the following sense using exp/imp

    8.0.5 (AR8ISO8859P6) - > 8.1.7 (AR8ISO8859P6) - > 10G (AR8MSWIN1256)
    OR
    8.0.5 (AR8ISO8859P6) - > 8.1.7 (AR8MSWIN1256) - > 10G (AR8MSWIN1256)

    Please advice

    Thank you

    Full database scan is necessary.

    Most likely, it is the question. I should have been more precise and should have said that the csscan race must be for the 'full' range, i.e.:

    csscan fromchar = ar8mswin1256 tochar = arm8mswin1256 full = y

  • character set and block corruption

    Hi master,

    It is not a kind of question, but a discussion...

    I would like to know how we can find the character set of database with dynamic display (under Oracle 10.2)? can we change after the installation of the database of characters?

    in fact I was facing a problem when you import a .dmp file...


    I was importing a dmp to oracle oracle 10.2 10.2 but the character set is different, so importation has not been started, he said possible character set conversion...

    and another topic is very different from the previous... What are the causes of corruption block?

    So what is the solution for this? I searched the net and got "try the new export file error or a State to support."

    and what is the difference between NLS_NCHAR_CHARACTERSET and NLS_NCHAR_CHARACTERSET? and how they affect datbase internal operation?

    any suggestion is appreciated


    Thanks and greetings

  • Sometimes, the Firefox doesn't recognize a character set

    Firefox can not decode some English text characters or symbols and instead of characters appear a kind of codes. Just like you would surf the Chinese website without the Chinese character set.

    Like this here

    Why is it so in Firefox? I've never seen what happens in Internet Explorer.

    Pages that use Unicode (UTF-8) format display a small box with the hex code if the character cannot be displayed.
    Which allows you to search the character in a table.

    If you see such a box with hexadecimal code in it, then it means that Firefox cannot map a character to a specific font, and you will need to install a font that covers the affected characters.

    In your case you are missing fonts and font support if it occurs on sites that use the IDEOGRAM.

    You will see something similar on Windows XP if you visit pages that use complex scripts (e.g. hindi and Arabic).

    Windows XP account very basic language support installed by default.

    There are many languages in the world and there are still languages that may require special fonts.

    You probably can't read, so it's your choice if you want to install a font for these pages or just accept the small squares with the hex code.

    Does anyone know what charset LPX uses for the words when you export a project at noon?

    I have set in Hungarian language of OS X. The correct character set for the Hungarians should be ISO-8859-2 (Latin 2), yet when I export a logical project that uses these words at noon, the external drive is not displayed correctly the

    That is to say. o is displayed as Ăł or similar, any set of characters I use in other software

  • Character set OCR

    Greetings,

    I am very new to machine vision, I am creating a number plate recognition system, I trained each character set in the license plate in the formation of OCR and when im opening each individual character image, sound successfully converts it to a string, but to an entire image (of the plate) its does not (I'm '?') I tried using KING for selection of specific areas but does not work... I don't know what seems to be the problem please help.

    You must connect the region of interest to the vi IMAQ OCR read text 3.

    The following example shows how to use the screw of OCR:

    C:\Program NIUninstaller Instruments\LabVIEW\examples\Vision\2. Functions\OCR\OCR first Example.llb\OCR first Example.vi.

    With this example, you can even load your character set file and try on your images.

  • Character set for message conflict

    I am running Win XP Pro w/SP3 and IE7 and OE6 support. When you try to send the entire copy & pasted text of a long article in the NY Times, I get the "conflict message character set" window which offers three choices, send as, Send as Unicode, or cancel (and reissue). It is the first time that I've ever known this error message when sending by e-mail of this kind. Although I sent the message twice, once for each of the two formatting options, none of my many recipients received the message. Since there is clearly no Western European NON-ISO or character sets Windows in the body of my email, what other reasons might be incited the error message? I even tried to copy the text into Notepad, and then copy and paste in OE6 nothing is helping.

    The problem seems to have resolved itself and without apparent reason.

  • Windows mail in vista giving the message "character set conflict."

    When I send an email, sometimes I get the error message "character set conflict."

    I use Windows Mail & Vista.

    In the options, I chose to send in HTML and Western European encoding

    Any suggestions?

    Are these replies to messages?  If Yes, it could be the original message has a different coding and that is why the conflict.  I think you can probably ignore it.
