Mixed Character Sets - UTF8

We have database with texts stored in mixed character sets.
DB charset is CL8MSWIN1251, but real data in CL8MSWIN1251, WE8MSWIN1252, EE8MSWIN1250.
We want convert this DB to UTF8 charser. Simple import/export will not help in this situation. Only CL8MSWIN1251 will be converted propertly.
Anyone know solutions for this situation?
Thank you in advance!

If the data is segmented so that character set 1 data is in a table and character set 2 data is in another table then you may have a chance to salvage the data with help from support. The idea would be to first export and import only your CL8MSWIN1251 data to UTF8. Be careful that your NLS_LANG is set to CL8MSWIN1251 for export so that no conversion takes place. Confirm the import is successful and remove CL8MSWIN1251 data from database. Oracle support can now help you override the character set via ALTER database to say MSWIN1252. Now selectively export/import this data, again make sure NLS_LANG is set to MSWIN1252 for export so that no conversion takes place. Confirm the import is successful and remove MSWIN1252 data from database. And then do the same steps for 1250 data.

Character sets - UTF8 or Chinese

Hi,
I am looking into enhancing the application I have built in Oracle to save/display data in Chinese & English. I have looking into how to change the character set of a database to accept different languages i.e. different characters.
From what I understand I can create a database to use a Chinese character set (apparently English ascii characters are also a part of any Chinese character set) or I can set the database to use a unicode multi-byte character set (UTF8) - which seems to be okay for all languages.
Has anyone had any experience of a) changing an existing standard 7 byte ascii database into database which can handle Chinese and/or b) the difference/ implications between using a Chinese and unicode character sets.
I am using Oracle RDBMS 8.1.7 on SuSE Linux 7.2
Thanks in advance.

NATIONAL CHARACTER SET UTF8

Hi,
on 10g, on Win 2003, how to verify if database is NATIONAL CHARACTER SET UTF8 ?
Thank you.

SELECT *
FROM v$nls_parameterswill show you all the NLS parameters. You're presumably looking for the row where parameter = 'NLS_NCHAR_CHARACTERSET' though there may be a few more parameters that you're interested in.

How to SET CHARACTER SET UTF8

I am looking to execute something like the stmt "SET CHARACTER SET UTF8"
However if i put the above stmt in a SQLDBC_Statement_execute call, i get fail message.
I should also mention here that, SQLDBC_Connection_connect call provides a way to provide the character set as one of the parameter. Is that the only way we can set character set from an application while using SQLDBC ?
Regards
Raj

Hi Lars,Elke and Thomas,
Thanks to all of you for your valuable input. Honestly speaking i'm little lost on how to go about this requirement of unicode support for my application. Please allow me some more time to investigate this and then get back to you.
In my application for all other databases a simple execution of "SET CHARACTER SET UTF8" is all that's been done to set the support for UTF-8. So, I really need to figure out what all changes needs to be done in the app if this is not going to work.
In the meantime something more caught my attention while i was using this command:
sqlcli MAXDB1=> \dc domain.columns
Table "DOMAIN.COLUMNS"
Column Name
Type
Length
Nullable
KEYPOS
SCHEMANAME
CHAR UNICODE
32
YES
OWNER
CHAR UNICODE
32
YES
What does the type 'CHAR UNICODE' for Type means here?

Can a db with character set UTF8 be restored to AL32UTF8?

Hello Everyone,
Good Day.
Our present production and non-production databases are configured with NLS_CHARACTERSET as UTF8. However, as we are in the process of migrating to a new server, we intend to configure the new databases with NLS_CHARACTERSET as AL32UTF8 (which is the recommended option as per our research. Moreover, came to know that for Weblogic schemas and repositories to work, NLS_CHARACTERSET must be AL32UTF8).
As we would be restoring from a backup to the new instance created on the new server, kindly help us understand if any issues might arise while restoring due to both being different charactersets?
Warm Regards,
Vikram.

Hi Robin,
Thank you for the update. Our DB is too huge and contains many schemas to try for a data pump. Hence we had planned for a restoration which might be simpler task with lesser downtime.
Perhaps, one option would be to create the instances with UTF character set itself and then change it once the migration activity has been completed.
Also, could you please throw some light on the two character sets as to which one is better and why?
Warm Regards,
Vikram.

China character set (UTF8)

Hi All,
We have a problem showing report with china character set.
We use Crystal Report 9. when I am getting the data from the DB with other application(Oracle SQL developer) I can see the china character well.
When I am using Crystal I am getting garbage.
In the regional setting I checked all the relevant checkbox for Asian language and code page conversion table.
The NLS_LANG is define as AMERICAN_AMERICA.AL32UTF8.
1) Does Crystal Report 9 support UTF8?
2) There is any 'check list' That I can check if all my setting (on my machine) are correct?
3) Any other idea?
Thanks,
Amos

Hi Amos,
It should work but you will need to use a Unicode font. Try setting your field fonts in CR to MS Ariel Unicode and test again.
Thank you

Character set migration error to UTF8 urgent

Hi
when we migrated from ar8iso889p6 to utf8 characterset we are facing one error when i try to compile one package through forms i am getting error program unit pu not found.
When i running the source code of that procedure direct from database using sqlplus its running wihtout any problem.How can i migrate this forms from ar8iso889p6 to utf8 characterset. We migrated from databas with ar8iso889p6 oracle 81.7 database to oracle 9.2. database with character set UTF8 (windows 2000) export and import done without any error
I am using oracle 11i inside the calling forms6i and reports 6i
with regards
ramya
1) this is server side program yaa when connecting with forms i am getting error .When i am running this program using direct sql its working when i running compiling i am getting this error.
3) yes i am using 11 i (11.5.10) inside its calling forms 6i and reports .Why this is giving problem using forms.Is there any setting changing in forms nls_lang
with regards

Hi Ramya
what i understand from your question is that you are trying to compile a procedure from a forms interface at client side?
if yes you should check the code in the forms that is calling the compilation package.
does it contains strings that might be affected from the character set change???

it shows me some symbol for Marathi words ..
please help me out.

XML data from BLOB to CLOB - character set conversion

Hi All,
I'm trying to solve a problem with a character set conversion in PL/SQL in the following scenario:
1. source is an XML as a BLOB variable.
2. target is an XML as a CLOB variable.
3. the problem I have is the following:
- database character set is set to UTF-8
- XML character set could be anything (UTF-8, ISO 8859-1, ISO 8859-2, ASCII, ...)
- I need to write a procedure which converts the source BLOB content into the target CLOB taking into account the XML encoding and converts it into the DB default character set (UTF8).
I've been able to implement a simple conversion function. However, this function expects static XML encoding ISO-8859-1. The main part of the function looks as follows:
buffer := UTL_RAW.cast_to_varchar2(
UTL_RAW.convert(
DBMS_LOB.SUBSTR(source_blob_variable, 16000, pos)
, 'American_America.UTF8'
, 'American_America.we8iso8859p1')
Does anyone have an idea how to rewrite the code to handle "any" XML encoding in the source BLOB file? In other words, is there a function in Oracle which converts XML character set names into Oracle character set values (ISO-8859-1 to we8iso8859p1, UTF-8 to UTF8, ...)?
Thanks a lot for any help.
Julius

I want to pass a BLOB to some "createXML" procedure and get a proper XMLType in UTF8 character set, properly converted from whatever character set is the input in.As per documentation the generated XML has always the encoding set at the client side depending on NLS_LANG (default UTF-8), regardless of the input encoding, so I don't see a need to parse the PI of the XML:

Importing from a different character set

Oracle 8.1.7 / Windows NT
I'm trying to import a dump file which was created with character set WE8ISO8859P9. My database uses character set UTF8. Some of the records can't be inserted because of error "ORA-1401: Value too large for column". Is this because of the different character sets? If I switch my session to WE8ISO8859P9, imp says "character set conversion from x to y not supported."
How can I get these last records inserted? Here's an excerpt from the log:

How to change the character set of the D/b

Hello All,
When i issue the command
ALTER DATABASE CHARACTER SET UTF8
It gives me the error that I can only change the character set to a superset of the existing character set.
Is there any way i can change the character set without recreating the database.
TIA
Naveen

The existing character set is the basis for the new character set. This is fair enough, because the character set determines how the actual data is stored in the database. Allowing new characters is a minor change: completely re-encoding your entire database is not.
I'm afraid export, recreate and import is your only option.
Cheers, APC

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.

Database Character Set Change

Hi,
I am trying to change my database's(9i) character set US7ASCII to UTF8 .
There are some tables having CLOB columns which are stopping this from happening .
So I exported all those tables having CLOB columns and truncated them .
But there are some views also which have CLOB columns which are restricting me from changing the characterset further.
Any help will be appreciated.
Thanx

Hi,
I used the following after export and truncate of tables containing CLOB columns .
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET UTF8;
SQL> ALTER DATABASE CHARACTER SET UTF8;
ALTER DATABASE CHARACTER SET UTF8
ERROR at line 1:
ORA-12716: Cannot ALTER DATABASE CHARACTER SET when CLOB data exists
Pls help me out.
Thanx
