Character set conversion

Hi all

I have a 10.2.0.4 database with US7ASCII character set, which contains non-ascii, e.g. 'e' characters (chr (232)).

Now I would like to upgrade to 11.2 with character WE8ISO8859P15 using expdp/impdp, but these non-ascii characters are not imported correctly. I tried all possible combinations of settings LANG and NLS_LANG (on the exports and imports), but I always chr (191) as a result.

Is it possible to do the same thing (with, of course, the original values)?

Operating system is Linux.

Thanks in advance

Guido

Your options:

1 clone the database and upgrade to 11.2 keeping the current mess. Simple but certainly not recommended.

2. assuming that you can assign all non-ASCII characters to a set of unique characters, like WE8MSWIN1252, clone the database, upgrade to 11.2 and follow the procedure described in MOS 555823.1 Note to change the character set for this set of unique character. The note is probably a little too complex, but you should get the point. You can also search this forum some of my older replies. I think I described a version shortened the procedure somewhere Note: you will get a database in the character set of the current data, not necessarily WE8ISO8859P15. However, there is no reason to insist on WE8ISO8859P15, unless all clients are on Unix type system and use that character set. If you move only a subset of the data, use of the database migrated in the form described in this point and then run a selective Data Pump to move only the data necessary for your target WE8ISO8859P15 (assuming that it already exists and cannot be recreated in a recommended character set). Note however that WE8MSWIN1252 supports different characters not supported by WE8ISO8859P15, such movement can cause the loss of character.

3 assuming you can assign all non-ASCII characters to a set of unique characters, like WE8MSWIN1252, clone of the database, upgrade to 11.2.0.4 and use The database for Unicode Migration Wizard to migrate the database to AL32UTF8 (Unicode) in place. The "Supposed Character Set database" property in the digital mock-up allows you specify the data identified unique character set so that CDS not US7ASCII migrate (converted) of all good character,. It is the most complex, but also more forward-looking option.

Thank you

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
VD

Changing database character set
Hi master,

I use oracle database XE on windows XP platform. This is just a test database. I need to import a schema into the database of the XE. but the problem is the character set conversion.

According to the oracle documentation, I tried to change the character set, but it is not worked.it says that ORA-12712: new character set must be a superset of the old character set. It is said

Export file created by EXPORT: V10.02.01 by conventional means
CAUTION: objects have been exported by < user >, not by you
import in WE8MSWIN1252 and AL16UTF16 NCHAR character set
import server uses the AL32UTF8 (possible character set conversion) character set

I have the same import NCHAR character set was made, but when I try to change the character above error is generated.

When I tried to change the character set it gives the above error.

What should I do?

Thanks and greetings

Please provide the details, how you tried to change the character set database and what character set.

As indicated in MetaLink Note 260192.1 ("Changing WE8ISO8859P1 / WE8ISO8859P15 or WE8MSWIN1252 (AL32) UTF8'"), AL32UTF8 is not a binary superset of these character sets and therefore conversion includes import/export steps in case you have non-US7ASCII character data in your database.

The MetaLink note explains how to make the change in detail, but I do not know if it is supported for 10g XE.

If you can afford it, the easiest way is probably to create/install a new database 10g XE by using the Unicode character database, I think that option when installing 10 g XE.

Kind regards

The original dump was expdp, we seek to import with IMP...

If it is conversely impdp flags it is an exp file - but this round way you get just this random error!

It seems that Data Dictionary has some convertible entries. you need to fix this all the objects individually as suggested in metalink Note 258904.1

Application object has a truncation and entered convertible. For truncation entries, you must increase the size of the column of the completed columns as shown in the .err log file. For convertible entries, you must perform the export/import. Note 1283764.1

Find the character set of the export dump file
I have a dump export, I don't have the log for this export dump file. How can I check the character set, as it had been exported?

Yes that's correct.

Rigth character set configurations in windows xp clients?
I would like to know who are rigth 'character parameters' that must be put in a machine under windows xp on several tools (including some Oracle, third party)? As long as I know the 'character' set parameters that influence the functioning of this tool are: "The language for non-unicode programs" under control panel language settings, the cmd chcp parameter, the parameter NLS_LANG registry and the encoding used in the file you want to load via SQLLoader. Italicized what I think... Could someone correct me if I'm wrong?

SQLLoader? Only thing that is important, is to put the NLS_LANG in the control file in line with the character set in which the file is encoded. The other parameters has no effect, I mean the command chcp cmd might be, the NLS_LANG in the registry could be another thing, etc.

sqlplus windows? Perhaps depends on the version of Oracle... I guess that the registry that NLS_LANG must be aligned with the "language for non-unicode programs"... The other parameters influence...

sqlplus cmd? , I guess that the registry that NLS_LANG must be aligned with the command chcp cmd character set. Other parameters has no effect.

PLSQL developer? Likes windows sqlplus? NLS_LANG and language for Non Unicode must be aligned?

TOAD? Like sqlplus windows?

Oracle SQLDeveloper? It is not influenced by one of "character set settings. It is in friendly Unicode

OleDb drivers (Oracle we and MS one)? As Oracle SQL developer? It is in friendly Unicode

exp/imp? No idea what...
SQL * Loader - if the data to load into the control file itself, NLS_LANG must be aligned with the character set of data. Otherwise, the character set of the data files should be prescribed by clauses CHARACTERSET and NLS_LANG must match the character set of all identifiers in the control file. If the control file is pure ASCII, character set NLS_LANG has no importance. Note that the language and territory of the NLS_LANG are relevant for the interpretation of dates and fractional numbers, unless explicit data format patterns are provided in the control file.

SQL * more GUI - character set NLS_LANG should be aligned with the system ANSI code page (defined by the o/s based on the "language for non-Unicode programs"). Elements of language and territory NLS_LANG influence implicit conversions of data types and the language of error messages.

SQL * more command prompt (console) - NLS_LANG must be aligned on the page of codes console (CHCP).

Developer PL/SQL, TOAD - not sure, can depend on version, probably identical to SQL * Plus GUI

Oracle SQL Developer - NLS_LANG is ignored. The locale user o/s session are used to initialize the language and territory. Character is in Unicode format.

OLE DB Oracle driver - it is more or less described here: http://download.oracle.com/docs/cd/B28359_01/win.111/b28431/using.htm#i1017221. If you need Unicode, NLS_LANG value mode. AL32UTF8.

In ODP .NET, the NLS_LANG character set is usually ignored. It is only used by OracleString.GetNonUnicodeBytes)

OLE DB MS driver - I don't know.

Exp/imp - the safest approach is to set to the character set of the database source of characters NLS_LANG. This can produce an output that is not readable on the screen, but if the queue to a file, it must be visible in an appropriate text editor.

VARCHAR2: 8 k limit when you use a multibyte character set
Hi people,
Apex 3.1.2 on 10.2.0.4 RAC on linux; the character set standard for my organization is AL32UTF8.
The apex database contains all non-US7ASCII character.

In a part of the URL, I just came from a package XML strings that are concatenated and passed as a parameter to Anychart.swf. Once my concatenated string exceeds 8 k I get "ORA-06502: PL/SQL: digital error or value." This is because on a UTF8 database are reserved to 4 bytes for each character; whether coded on several bytes, or not - and the varchar2 (32767) is exhausted.

It is a severe limitation as the XML table can easily exceed 8 k.

What choices do I have?
-If I change my database in US7ASCII he works my limit for the concatenation in a region with a real 32,767 characters? Better, but still limited.
-are there functions to force a single byte per character conversion - I don't think so, but just in case where...
-would spend using CLOB? I'm worried it might slow down processing low-response time is one of the main motivations for going to the whole problem in the first place.

My code looks like this:

DECLARE
Xml1 VARCHAR2 (4000);
xml2 VARCHAR2 (4000);
XML3 VARCHAR2 (4000);
xml4 VARCHAR2 (4000);
str1 VARCHAR2 (32767).

pkg_chart. Gen_Chart_Xml5
(p_chart = >...)
, p_Location = >...
, p_timescale = >...
, p_Day = >...
, p_RETURN1 = > xml1
, p_RETURN2 = > xml2
, p_RETURN3 = > xml3
, p_RETURN4 = > xml4
);
str1: = xml1. xml2 | XML3 | xml4;

.. .and later
var Chart1 = new AnyChart();
Chart1.SetData ("' | str1 |) ''');
Chart1.write ("chartDiv-1");

Right now my code fails in concatenation in str1 if the total length is more than about 8 k.
I've seen different messages about CLOB handling in the apex and it seems to be fraught with problems too: so I was wondering if anyone has any advice on how to best proceed. or could you show me an example to do something like this using CLOB instead.

Thank you very much!
Mark

Hello

I was about to hit you up an example when I spotted a recent blog post of someone I know called Morten Jensen.

His blog is here [http://theworldofjensenmo.blogspot.com/] and here is the relevant quote...

>
He must be a procedure which will be "buffer printing" CLOB. The procedure to come htp.prn with the PL/SQL Web Toolkit in the Oracle database allow up to 8192 characters to print at a time, which is too few in my case. So this function below will share a CLOB up to 256 character fragments and htp.prn them one at a time.

create or replace PROCEDURE HTP_BUF_PRN
(p_text IN CLOB
) AS
l_buflen INTEGER: = 256;
BEGIN

FOR i FROM 0... Floor (length (p_text) / l_buflen) LOOP
-HTP. PRN will not accept lines up to 8192 characters - that's why this function is required
HTP. PRN (substr (p_text, i * l_buflen + 1, l_buflen));
END LOOP;

-htp.prn (substr (p_text, LENGTH (p_text) - (LENGTH (p_text) mod l_buflen), LENGTH (p_text) mod l_buflen));

END HTP_BUF_PRN;
>

He hit me with that feeling of "why didn't I think that!

I hope this helps.

See you soon

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.

Character set for the words

Hello

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

P. S.

I submitted a bug report, as this seems to be a bug, but there was no reaction yet on the report

PS.

Never mind, I just realized the character encoding used is UTF-8

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.

I hope this helps.

Best regards

Christophe
