AMERICAN_AMERICA.TR8MSWIN1254
Thanks

Hi,
sorry missed that picture. What I now think is that you missing the possibility to display turkish characters on Linux. Is there a Turkish pack to install for Linux "(I'm no a Linux expert). Or are you using a lettertype which cannot display Turkish letters?

Oracle 8i us7ascii character set problem - help required urgent.

Hi frnds,
I have a oracle 8i database server installed on sun solaris os. The database character set is us7ascii. In one of the tables TIFF images are stored in a long column. I m trying to fetch these images using oracle 9i client and visual basic(oracle ODBC drivers). But i m unable to do so. I can not fetch special characters.
Is it because of the character set problem? but when i run my code on the server itself, i m able to fetch the images. I tried to fetch the images using oracle 8 i client on windows XP machine but could not do so. Are there any special settings that i have to do on the client side?

Indeed, it's an ODBC issue. Read this statement from Oracle:
From ODBC 8.1.7.2.0 drivers onwards it's NOT possible any more to
"disable" Characterset conversion by specifying for the NLS_LANG
the same characterset as the database characterset. There is now
ALWAYS a check to see if a codepoint is valid for that characterset.
Typically you will encounter problems if you upgrade an environment
that has NO NLS_LANG set on the client (or US7ASCII) and the database
was also US7ASCII. This incorrect setup allowed you to store characters
like èçàé in an US7ASCII database, with the new 8i drivers this is not possible
any more.
Basic problem is the 'wrong' characterset US7ASCII in the database. As long as no characterset conversion happens (that's the case on the unix server), special characters are no problem.

How to find Client Character set?

Hi,
I need to connect to remote database which is having different character set than the client. Ia there any method to display client character and Database character set from SQL Plus? Could someone please help me.
Thanks in Advance
Sree.

I guess you're using PL/SQL Developer?
(because I get that warning message too ;) )
The warning also continues with:
You can set the client character set thought the NLS_LANG environment variable or the NLS_LANG registry key.
If I execute some scripts from client (client character set WE8MSWIN1252 and database character set UTF8) will
it cause any problem?It depends on what kind of data you're loading/importing. (chinese characters for example)
I never had any problems at all, since I'm not using 'exotic' characters.
You can find related threads on http://asktom.oracle.com/pls/asktom/asktom.search?p_string=%22UTF8%22
and more explanations in the Oracle Globalization Guide: http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/toc.htm

i run my code on the server itself, i m able to fetch
the images. I tried to fetch the images using oracle
8 i client on windows XP machine but could not do so.You able to fetch the image , So it is not because of the character set.
First thing you need to consider is that use certified combination of OS , client and database server only. Check Certify - Oracle's Certification Matrices

If you have come across this problem and have solutions of it. That will be great.

Agent control character set problem

Hi,
here's my problem :
i've got the grid that's running on a RHES4 with an agent. On another RHES4, i've got 10g databases that run and another agent.
The repository database is configured like this :
nsl_language = AMERICAN
nls_territory = AMERICA
character set = AL32UTF8
all the uploads from the agent on the RHES4 where the grid is installed are ok.
On the other server, as soon as there's an UTF8 character in a xml file (like " é " ou " ' "), the upload fails and the agent stops.
in the logs, it s clear it comes from this. I've deleted all the occurences of UTF8 characters in the xml file and restarted the upload and it's ok...
I've tested different configurations but without success.
Any clue ?
Alivetu

Thanks for the reply,
NLS LANG is set on the 2 machines with FRENCHFRANCE.WE8ISO8859P15
I've added the line '<?xml version="1.0" encoding="ISO-8859-1"?>' at the beginning of the xml file that doesn't work and made a 'emctl upload'....it has passed and the agent has stopped arrived to another UTF8 xml file...
So, it really is a character set problem but where to set it ???

Using translate function to correct character set problem....

I have a table(TBL_STOCK) on Oracle XE.
Rows come from sql server 2005 with a trigger on sql server table via the linked server.
But there is a character set problem with some character like İ,Ş,Ğ.
They change to Ý,Þ,Ð. in Oracle.
How can i correct these ? Do you suggest the TRANSLATE function ?
What do u think, if i create an After Insert trigger on Oracle table(TBL_STOCK) and convert these character using the Translate function when they inserted from sql server.
Anyone have any other ideas that can be more efficient. Any thoughts appreciated.
Thanks in advance.
Adam
PS:The NLS_CHARACTERSET of Oracle is AL32UTF8.

It is sql server 2005 and Collation is SQL_Latin1_General_CP1_CI_AS

Db character set, client character set, OS character set

Hi,
I'm confused about all these character set: DB character set, National character set, Client character set, Operating system character set, NLS_LANGUAGE parameter in init.ora file, NLS_LANG parameter in registry.
Can anyone explain the differences of these to me?
Many thanks.

Client-side greek character set problem

hi everyone,
i am a .net developer and absolutelly new to oracle, its my first project that i have make oracle and .net co-operate and it's proving to be a nightmare!
i ll try and provide as much info as possible to you
we have a unix sap server with oracle 10.something on it (i can check exactly what version if that's of importance) and i am writting a .net app which accesses the oracle db and retrieve some data we need
the locale settings of the db are american_america.we8dec and i cannot temper with that machine, it is out of the question
i have made the connection to the db using just connection string info, not tns and stuff, and i have set my dev machine's nls_lang to we8dec everywhere i could find it with a 'find' in the registry
however my app displays the data (which is in greek) showing random symbols that obviously make to sense
furthermore when i connect to the db via sql developer or navicat i still get the same symbols
i understand it is something to do with my client system's settings but i cant work it out
i would really appreciate your help i am sorry if it is something very simple but i just cant find it
thanks

It's a brand new universe, but if you take it step by step I'm sure you'll do fine. Get someone near with Oracle dev and dba background to guide you, so you don't get stuck or go down broken roads.
we have a unix sap server with oracle 10.something on it (i can check exactly what version if that's of importance)It is of importance most of the time. Down to at least 4 positions (for example, "10g" is just a marketing label and mostly useless in a techincal context - 10.2.0.5 is more like it).
Also mention platform (unix OS) details.
and i am writting a .net app which accesses the oracle db and retrieve some data we needHow is the to-be retrieved data loaded or entered to begin?
>

SQL> select * from nls_database_parameters where parameter like '%CHARACTERSET';
and i have set my dev machine's nls_lang to we8dec everywhere i could find it with a 'find' in the registryDoes your dev (client) machine use a "we8dec" character set? Likely, as you seem to be on Windows, you should have set nls_lang client char set part to match win-1252 or whatever client char set (code page) is in use.
however my app displays the data (which is in greek) showing random symbols that obviously make to senseNo surprise since DEC character set does not have a greek character in its repertoire. If I'm not all mistaken DEC MCS (or similar) is the charcter set to which WE8DEC corresponds. You could check against mapping table in Locale builder, but available characters should be per following link or close enough.
http://czyborra.com/charsets/iso8859.html#ISO-8859-1 (second chart is DEC-MCS)
Please provide a sample of those "random symbols".
furthermore when i connect to the db via sql developer or navicat i still get the same symbolsIf that's Oracle SQL Developer it should give a true picture of what's actually stored - which, unfortuantely, seem to be invalid character data.
i understand it is something to do with my client system's settings but i cant work it out See above. But even if you correctly setup client environment, the db won't be able to store the data if databas character set is in fact WE8DEC.
>
i would really appreciate your help i am sorry if it is something very simple but i just cant find it I'm not sure, but it would seem as you have been given unfeasible conditions to work from. So maybe it's not up to you, until a character set migration has been taken place.
In general, the Database character set should be a suitable superset (repertoire) that covers all current (and hopefully future) language alphabets requirements.
You might want to search forum for 'we8dec' to find previous related discussions.
Edit:
- Added url with DEC MCS.
- platform info

Setting the database character set problem!

I'm sorry if this is beaten to death, I've read the FAQ and many questions in this forum and I didn't find it.
I want to change the database character set from the beginning. Where do I place the NLS_CHARACTERSET=EL8ISO8859P7 ?
I know I can alter the existing database character but EL8ISO8859P7 is not a superset of WE8ISO8859P1 and I don't want to go to Unicode yet...
Do I have to create a brand new database or can I just alter a script and restart it ?
I didn't find any nls_setting in the database creations, uh, wizard.
Please be as specific as possible because as you can understand I'm not what you can call a db expert...
Thank you.

which version of Oracle? these things change between versions.
v7 - update sys.props$ (unsupported!)
v8.0 - rebuild database
v8.1 - alter database change characterset
remember, backup and test before you do this on a used/production database!
good luck, Nogah.

Greek Character Set Problem

Dear All,
We are currently working on Oracle 8i to 9i migration and unicode implementation of an application SampleDB. We encountered an issue (described below) while the data migration.
Issue:
We have a database in oracle8i with
NLS_LANGUAGE AMERICAN
NLS_CHARACTERSET WE8ISO8859P1
NLS_NCHAR_CHARACTERSET WE8ISO8859P1
The character set WE8ISO8859P1 does not support GREEK language. The user inserts/modifies records in this database from the front-end. The front end installed in the client machine has the following setting:
Control Panel->Regional settings ->Advanced ->Language for non-unicode programs = Greek
Oracle client installed in English
Greek characters have been inserted/ updated into this database and retrieved and displayed correctly by the GUI.
Note: Greek data has been inserted into WE8ISO8859P1 database which does not support Greek characters.
Hence the actual data that is stored in the database are not Greek. Only while displaying, they are getting converted into Greek characters due to the settings in the client machine.
Requirement: Migrate the database to Oracle 9i - Unicode.
While migration, we need to eliminate any data discrepancy and make sure the data in the Unicode database is in Greek.
Can any one suggest us a method to do the migration to avoid the above mentioned problem?
Further, can any one tell us a way to verify what characters get stored in the database and help us identify if they are real Greek characters

The character set WE8ISO8859P1 does not support GREEK language.If you want to support Greek characters (or 'math' symbols), look at the EL8... char sets.
Control Panel->Regional settings ->Advanced
->Language for non-unicode programs = Greek
Oracle client installed in EnglishThis is dependent on the app and Windows. What is the NLS_LANG value in this Oracle home? NLS_LANG should be adjusted to fit the application.
Note: Greek data has been inserted into WE8ISO8859P1
database which does not support Greek characters.
Hence the actual data that is stored in the database
are not Greek. Only while displaying, they are
getting converted into Greek characters due to the
settings in the client machine.Maybe character data does not get converted, but still shown as greek.
Further, can any one tell us a way to verify what
characters get stored in the database and help us
identify if they are real Greek charactersIn the case of character data, what you really store depends on the db and the character values. You can use dump or some other PL function to look at the values.
There's a Database Globalization Support Guide for 9.2 that might be useful.

Character set Problem (From WE8ISO8859P1 to EL8MSWIN1253)

Hi there,
I would like to describe a problem that I face with import, export and Greek characters.
I have two databases with the following characteristics
Source database:
O/S version Windows
Database version à 10GR2
NLS_CHARACTERSET à WE8ISO8859P1
NLS_NCHAR_CJARACTERSET à AL16UTF16
NLS_LANGUAGE à GREEK
NLS_TERRITORY à GREECE
Target database:
O/S version Windows
Database version à 10GR2
NLS_CHARACTERSET à EL8MSWIN1253
NLS_NCHAR_CJARACTERSET à AL16UTF16
NLS_LANGUAGE à GREEK
NLS_TERRITORY à GREECE
From the source database, using the export tool I am exporting a table (TABLE_A) which contains Greek records. At this point I want to mention that the from the source database I am able to read the Greek characters from TABLE_A by using sqlplus i.e (select * from table_a;)
On the target database by using import I load the table TABLE_A into the database.
When I select the newly imported TABLE_A on the target database I am not able to read the Greek characters.
I have tested various scenarios by using different values for the NLS_LANG variable regarding export and import clients but I did not manage to read the Greek characters on the target database.
If anyone faced the same or a similar problem please I am asking for assistance.
Thank you in advance

Please, review this thread:
Re: Arabic Character set conversion-help needed
The thread describes a similar issue for Arabic data. Therefore, when reading the thread, substitute 'WE8ISO8859P1' for 'AR8ISO8859P6', 'EL8MSWIN1253' for 'AR8MSWIN1256', and 'Greek' for 'Arabic'.

DB Creation(character set Problem)

HI,
I am in the process of creating new database from the full export dump file which i got from client. In the export logfile i can see,
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set
I am creating the database manually at my site and planning to import that full export dumpfile from the client.
Do i need to create the DB with national character set WE8MSWIN1252 or can i also use character set as AL32UTF8
I want to se the correct character set so that my import doesn't fails because of charactor set problem.
Please help me.
Oracle Version At client site:9.2.0.1
OS :Windows
Oracle Version at my site:9.2.0.1
OS:LINUX
Thank You..

I can't answer your question because of several things.
The first is that all versions of 9i are currently in desupport and it has been years since I've seen one.
But if I was forced to work with 9i I certainly wouldn't do anything at all until I had patched to 9.2.0.8.
My recommendation would be, unless someone else can help you, to try it and see what happens.
Nothing ventured nothing gained.

Turkish character set problem in Windows

Hi;
I am developing an application in VB.net 2005 using an oracle database on the Linux server.
I have Oracle Client installed on my windows machine.
I installed ODT.NET and ODP.Net by executing ODTwithODAC10202.exe on the client side.
I am using Turkish character set in Windows.
I have couples of problems I couldn't manage..
1. I cannot use 'i' character in database password since it leads to error: 'Invalid user ıd or password'
2. I cannot use Pooling parameter in my oracle connection string, since it leads to error 'Pooling is invalid attribute of connetion string'
3. I cannot store Turkish characters to the database.
