Setting Oracle XE character set

Is there any way to set NLS_CHARACTERSET = WE8ISO8859P15 in Oracle XE?

I believe it can be answered by reading documentation/release notes:
XE comes in two flavours: A Western European Edition and an Universal Edition
Oracle Database 10g Express Western European Edition - Single-byte LATIN1 database for Western European language storage, with the Database Homepage user interface in English only. The character set is WE8MSWIN1252.
Oracle Database 10g Express Universal Edition - Multi-byte Unicode database for all language deployment, with the Database Homepage user interface available in the following languages: Brazilian Portuguese, Chinese (Simplified and Traditional), English, French, German, Italian, Japanese, Korean and Spanish. The character set is AL32UTF8.

How to set or change character set for Oracle 10 XE

Installing via RPM on Linux.
I need to have my database set to use UTF8 and WE8ISO8859P15 as the character set and national character set. (Think those are in the right order. If not, it's the opposite.)
If I do a standard "yum localinstall rpm-file-name," it installs Oracle. I then run the "/etc/init.d/oracle-xe configure" command to set my ports.
Every time I do this, I end up with AL32/AL16 character sets.
I finally hardcoded ISO-8859-15 as the Linux 'locale' character set and set this in the various bash profile config files. Now, I end up with WE8MSWIN1252 as the character set and AL16UTF16 as the national character set.
I've tried editing the createdb.sh script to hard code the character set types and then copied that file over the original while the RPM is still installing. I've tried editing the nls_lang.sh script to hard code the settings there and copied over the original shell script while the RPM is still installing.
Doesn't matter.
HOW can I do this? If I wait until after the RPM is installed and try running the createdb.sh file, then it ends up creating a database but not doing everything properly. I end up missing pfiles or spfiles. Various errors crop up.
If I try to change them from the sql command line, I am told that the new character set must be a superset of the old one. It fails.
I'm new to Oracle, so I'm treading water that's uncharted. In short, I need community help. It's important to the app I'm running and attempting to migrate from to maintain these character sets.
Thanks.

I don't think you can change Oracle XE character set. When downloading Oracle XE you must choose to download:
- either the Universal Edition using AL32UTF8
- or the Western Euopean Edition using WE8MSWIN1252.
See http://download.oracle.com/docs/cd/B25329_01/doc/install.102/b25144/toc.htm#BABJACJJ
If you really need UTF8 instead of AL32UTF8 you need to use Oracle Standard Edition or Oracle Entreprise Edition:
these editions allow to select database character set at database creation time which is not really possible with Oracle XE
Note that changing environment variable NLS_LANG has nothing to do with changing database character set:

Oracle database character set

Hello all -
Please help..................
I will be exporting/importing 6/7 users/schemas/data from one database to the another database on solaris. Users are created.
I am confused about NLS_LANG variable and database characterset.
I have the following questions -
1. What is impact of NLS_LANG variable setting of user session while import/export the data ?
2. Why do we need to set this NLS_LANG user session variable before export/import ?
3.If NLS_LANG variable is not set (doesnot have any value) what would happen ?
4. If I have to set NLS_LANG varible, what should I set it to?
5. How can I see the characterset of my database?
6. Where can I get more info about database charaterset and What are the valid values for database characterset and NLS_LANG varibale ?
Any help would really appreciated...
Thanks a lot.....
RAMA

1. What is impact of NLS_LANG variable setting of user session while import/export the data ?
On export, the data will be converted from the database character set to the character set specified by NLS_LANG. In import, the database will assume that the data is in the character set specified by NLS_LANG and use that value to perform the conversion to the database character set if the two values to not match.
2. Why do we need to set this NLS_LANG user session variable before export/import ?
If your database character set is the same as your OS, you don't necessarily have to set NLS_LANG. For instance, if you have a US7ASCII db, and your OS locale is set to AMERICA_AMERICAN.US7ASCII, there won't be any problems. The only time it's really important to set this is when the db and OS settings don't match.
3.If NLS_LANG variable is not set (doesnot have any value) what would happen ?
If your database character set doesn't match your OS, the data could be garbled because the db will incorrectly transcode the data on import/export.
4. If I have to set NLS_LANG varible, what should I set it to?
Depends on what your database character set is set to (see below).
5. How can I see the characterset of my database?
select * from nls_database_parameters and look for the value set for the NLS_CHARACTERSET parameter. Don't get confused by the NLS_NCHAR_CHARACTERSET, that's for NCHAR datatypes.
So, for instance, if your NLS_CHARACTERSET value is set to UTF8, you would set NLS_LANG to .UTF8 (the dot is important because that's actually shorthand for territory_language.characterset, or language_territory.characterset, I can never remember which comes first. In any case, use the dot). For example:
setenv NLS_LANG .UTF8
6. Where can I get more info about database charaterset and What are the valid values for database characterset and NLS_LANG varibale ?
It's all in the Oracle documentation.
hope this helps.

[urgent] oracle character set and national character set !!(dictionary)

Hi. everyone.
What is the oracle dictionary that contains information of
oracle character set and national character set?
I checked v$database, but there was not the information.
It seems that there are some differences between "nls_* " init parameters
and the database character set.
"Alter database backup controlfile to trace" gave me the character set of db,
but I would like to know whether there are oracle dictionary regarding them.
Thanks in advance. Have a nice day.
Best Regards.

I found the dictionary which contains the information of character set and
natiional character set of database.
select * from nls_database_parameters
where parameter like '%CHARACTERSET';
Thanks for reading.
Have a good day.
Best Regards.

Conversion error, from character set 4102 to character set 4103

Hi,
We've developed a JCO server(in Java) with an ABAP report the function provided by the JCO server.
MetaData:
     static {
          repository = new Repository("SMSRepository");
          fmeta = new JCO.MetaData("ZSMSSEND");
          fmeta.addInfo("TO", JCO.TYPE_CHAR, 255,   0, 0, JCO.IMPORT_PARAMETER, null);
          fmeta.addInfo("CONTENT", JCO.TYPE_CHAR, 255,   0, 0, JCO.IMPORT_PARAMETER, null);
          fmeta.addInfo("RETN", JCO.TYPE_CHAR, 255,   0, 0, JCO.EXPORT_PARAMETER, null);
          repository.addFunctionInterfaceToCache(fmeta);
Server parameters:
       Properties prop = new Properties();
       prop.put("jco.server.gwhost","shaw2k07");
       prop.put("jco.server.gwserv","sapgw01");
       prop.put("jco.server.progid","JCOSERVER01");
       prop.put("jco.server.unicode","1");
       srv = new SMSServer(prop,repository);
If we run JCO server in both my client machine(from developer studio) and in the WAS machine(stand alone Java program), everything is ok. In the Abap side, the SM59 unicode test return the destination is an unicode system, and the ABAP report call the function can run smoothly.
But we package this JCO server to a web application and deploy to WAS, problem occured. The SM59 unicode test still say the destination is an unicode system. But the ABAP report runs with an ABAP DUMP:
Conversion error between two character set
RFC_CONVERSION_FIELD
Conversion error "RETN" from character set 4102 to character set 4103
A conversion error occurred during the execution of a Remote Function
Call. This happened either when the data was received or when it was
sent. The latter case can only occur if the data is sent from a Unicode
system to a non-Unicode system.
I read the jrfc.trc log, it shows it receives data in unicode 4103(that's ok), but send data in unicode 4102(that's the problem).4102 is UTF-16 Big Endian and 4103 UTF-16 Little Endian. Our system is windows on intel 32 aritechture, so based on Note 552464, it should be 4103.
Why it sends data (Java JCO server send output parameter to ABAP) in 4102?????
What's the problem??? Thank you very much!!

Oracle Database Character set and DRM

Hi,
I see the below context in the Hyperion EPM Installation document.
We need to install only Hyperion DRM and not the entire Hyperion product suite, Do we really have to create the database in one of the uft-8 character set?
Why it is saying that we must create the database this way?
Any help is appreciated.
Oracle Database Creation Considerations:
The database must be created using Unicode Transformation Format UTF-8 encoding
(character set). Oracle supports the following character sets with UTF-8 encoding:
l AL32UTF8 (UTF-8 encoding for ASCII platforms)
l UTF8 (backward-compatible encoding for Oracle)
l UTFE (UTF-8 encoding for EBCDIC platforms)
Note: The UTF-8 character set must be applied to the client and to the Oracle database.
Edited by: 851266 on Apr 11, 2011 12:01 AM

Srini,
Thanks for your reply.
I would assume that the ConvertToClob function would understand the byte order mark for UTF-8 in the blob and not include any parts of it in the clob. The byte order mark for UTF-8 consists of the byte sequence EF BB BF. The last byte BF corresponds to the upside down question mark '¿' in ISO-8859-1. Too me, it seems as if ConvertToClob is not converting correctly.
Am I missing something?
BTW, the database version is 10.2.0.3 on Solaris 10 x86_64
Kind Regards,
Eyðun

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.

How to Set my own Character Set in DBMS_LOB Package

Hello All
A Very Good Morning.
I am using DBMS_LOB.CONVERTTOCLOB To convert data in BLOB to CLOB.
My Database Character set is AL32UTF8.
I want to change that one to WE8ISO8859P15.
In DBMS_LOB.CONVERTTOCLOB package there is a parameter BLOB_CSID.
In the Documentation it is said that I can set this value to a desired Character set.
But the value should be of Integer Type.
How to set the Character Set conversion.
Regards
Madhu K

To get the id you looking for run:
select * from V$NLS_VALID_VALUES where parameter='CHARACTERSET';make sure your characterset is in there and then run:
select NLS_CHARSET_ID('WE8ISO8859P15') from dual;This is the id or number you want to pass into the DBMS_LOB.CONVERTTOCLOB.

How to set Multi Byte Character Set ( MBCS ) to Particular String In MFC VC++

I Use Unicode Character Set in my MFC Application ( VC++) .
now i get the output ठ桔湡⁫潹⁵潦⁲獵 (like this )character and i want to convert this character in english language (means MBCS),
But i need Unicode to My Applicatiion. when i change the Multi-Byte Character set It give Correct output in English but other Objects ( TreeCtrl Selection ) will perform wrongly . so i need to convert the particular String to MBCS
how can i do that ? In MFC

I assume your string read from your hardware device is an plains "C" string (ANSI string). This type of string has one byte per character. Unicode has two bytes per character.
From the situation you explained I'd convert the string returned by the hardware to an Unicode string using i.e. MultibyteTowideChar with CP_ACP. You may also use mbstowcs or some similar functions to convert your string to an Unicode string.
Best regards
Bordon

Import Term Set with Greek character set

I have been trying to import a Term Set, from a CSV file created using the standard template of SharePoint 2010, however only the first 10 terms get imported. As far as I know, there is no such limitation and the total number of terms in the Term Store
is very small. The import procedure completes with no error message.
Can anybody enlighten me as to why this is happening?
This is a sample of the CSV I am using:
"Term Set Name","Term Set Description","LCID","Available for Tagging","Term Description","Level 1 Term"
"ΜΟΑ - Δήμοι","Δήμοι Κύπρου.",,True,,"Αγγαστίνα"
,,,True,,"Αγγλισίδες"
,,,True,,"Αγγολέμι"
,,,True,,"Αγιά (Aγιά Κεπίρ)"
,,,True,,"Αγία Άννα"
,,,True,,"Αγία Βαρβάρα Λευκωσίας"
,,,True,,"Αγία Βαρβάρα Πάφου"
,,,True,,"Αγία Ειρήνη Κερύνειας"
,,,True,,"Αγία Ειρήνη Λευκωσίας"
,,,True,,"Αγία Μαρίνα Κελοκεδάρων"
,,,True,,"Αγία Μαρίνα Ξυλιάτου"
,,,True,,"Αγία Μαρίνα Σκυλλούρας"
,,,True,,"Αγία Μαρίνα Χρυσοχούς"
etc.
Note: The CSV file has been saved with UTF-8 encoding and the first 10 terms (that do get imported) correctly appear in the Term Store.

Hi,
From your description, I know you do not import all terms when you import a term set.
To reproduce your issue, I copied the items in your issue to my environment, then imported them in to my SharePoint. All items had been imported in my SharePoint, but I found
that default displaying items were the first 10 terms. The screenshot below is my result:
Please click here to find your other terms.

NLS CHARACTER SET 변경 방법 (ORACLE 7)

NLS CHARACTER SET 변경 방법 (ORACLE 7)
======================================
PURPOSE
이 자료는 Oracle RDBMS SERVER에서 NLS CHARACTER SET 변경 방법에 대한
내용을 소개한다.
[ ORACLE 7 에서만 가능 ]
데이타베이스의 CHARACTER SET은 데이타 딕셔너리 테이블인 sys.props$에
들어 있다.
SQL>desc sys.props$
Name Null? Type
NAME NOT NULL VARCHAR2(30)
VALUE$ VARCHAR2(2000)
COMMENT$ VARCHAR2(2000)
SQL>column c1 format a30
SQL>select name c1, value$ c1 from sys.props$;
C1 C1
DICT.BASE 2
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_NUMERIC_CHARACTERS .,
NLS_DATE_FORMAT DD-MON-YY
NLS_DATE_LANGUAGE AMERICAN
NLS_CHARACTERSET US7ASCII
NLS_SORT BINARY
GLOBAL_DB_NAME NLSV7.WORLD
여기서 NLS_CHARACTERSET에 현재 DB의 CHARACTER SET이 들어 있는데
이 값을 변경하여 DB의 CHARACTER SET을 변경할 수 있다.
여기서는 US7ASCII에서 KO16KSC5601로 옮기는 경우를 알아보자.
우선 바꾸고자 하는 CHRACTER SET이 지원되는 지를 다음 명령으로
확인한다.
select convert('a','KO16KSC5601','US7ASCII') from dual;
만약 이 Select 문에서 ORA-01482 에러가 발생하면 지정한 CHARACTER
SET이 지원되지 않는 경우이며 에러가 발생하지 않으면 CHARACTER
SET을 변경할 수 있다.
작업을 하기 전에는 만약을 위해서 DB 전체를 백업 받아두도록 한다.
CHARACTER SET 을 잘못 변경하면 DB 를 OPEN 할 수가 없기 때문이다.
1. 다음의 Update문을 실행하여 CHARACTER SET을 변경한다.
UPDATE sys.props$
SET value$ = 'KO16KSC5601'
WHERE name = 'NLS_CHARACTERSET';
Update 시에 NLS_CHARACTERSET을 지원되지 않는 값으로 잘못 설정하거나
실수로 콘트롤 문자 같은 것이 들어가게 되면 DB가 Shutdown 된 다음에는
Startup 이 안되므로 Update 후에 다음 명령으로 확인을 한 다음에
Commit을 하도록 한다.
select name, value$
from sys.props$
where value$ = 'KO16KSC5601';
Select가 제대로 출력되면 Commit 하고 Shutdown 했다가 Startup 하게
되면 새로운 CHARACTER SET 값을 갖게 된다. SELECT가 안 되면 ROLLBACK
하고 UPDATE부터 다시 하도록 한다.
2. 환경 변수 NLS_LANG 을 변경한다.
.profile 에서
NLS_LANG=American_America.KO16KSC5601; export NLS_LANG
또는 .cshrc 에서.
setenv NLS_LANG American_America.KO16KSC5601
*** win95 및 winnt의 client에서는 registry editor에서 NLS_LANG 값을
맞추어준다.
주의 !!!
: 위의 작업을 하기 전에 발생할 가능성이 있는 문제점
1) update 중 KO16KSC5601 이나 US7ASCII 등에서 철자를 잘못 입력하시면,
db 재기동 후에, 다음과 같은 에러가 발생합니다.
ora-12708
12708, 00000, "error while loading create database NLS parameter %s"
2) KO16KSC5601과 US7ASCII의 비교
Character set : KO16KSC5601 인 경우
===================================
: double byte encoding schema 이므로, 한글의 경우 2 bytes 를 크기 1로
계산하는 함수들이 있습니다.
그리고, table , column name에 한글을 double quote 없이 사용할 수 있습니다.
예)
SQL> create table 시험1
2 (컬럼1 varchar(10));
가
a
홍길동
SQL> select length(컬럼1) from 시험1;
1
1
3
SQL> select lengthb(컬럼1) from 시험1;
2
1
6
Character set : US7ASCII 인 경우
=================================
: single byte 7 bit encoding 을 사용합니다.
한글로 된 table, column 이름 사용 시 double quote를 반드시 사용해야 한다.
예)
SQL> create table "사원"
2 ("사원이름" varchar2(10));
가
a
홍길동
SQL> select length("사원이름") from "사원";
2
1
6
SQL> select lengthb("사원이름") from "사원";
2
1
6
US7ASCII일 때에는 vsize, lengthb function의 결과가 length 함수와 모두
동일합니다.
cf) substr, substrb 함수도 위의 length, lengthb의 관계와 같음.

여기서 NLS_CHARACTERSET에 현재 DB의 CHARACTER SET이 들어 있는데
이 값을 변경하여 DB의 CHARACTER SET을 변경할 수 있다.
여기서는 US7ASCII에서 KO16KSC5601로 옮기는 경우를 알아보자.
우선 바꾸고자 하는 CHRACTER SET이 지원되는 지를 다음 명령으로
확인한다.
select convert('a','KO16KSC5601','US7ASCII') from dual;
만약 이 Select 문에서 ORA-01482 에러가 발생하면 지정한 CHARACTER
SET이 지원되지 않는 경우이며 에러가 발생하지 않으면 CHARACTER
SET을 변경할 수 있다.
작업을 하기 전에는 만약을 위해서 DB 전체를 백업 받아두도록 한다.
CHARACTER SET 을 잘못 변경하면 DB 를 OPEN 할 수가 없기 때문이다.
1. 다음의 Update문을 실행하여 CHARACTER SET을 변경한다.
UPDATE sys.props$
SET value$ = 'KO16KSC5601'
WHERE name = 'NLS_CHARACTERSET';
Update 시에 NLS_CHARACTERSET을 지원되지 않는 값으로 잘못 설정하거나
실수로 콘트롤 문자 같은 것이 들어가게 되면 DB가 Shutdown 된 다음에는
Startup 이 안되므로 Update 후에 다음 명령으로 확인을 한 다음에
Commit을 하도록 한다.
select name, value$
from sys.props$
where value$ = 'KO16KSC5601';
Select가 제대로 출력되면 Commit 하고 Shutdown 했다가 Startup 하게
되면 새로운 CHARACTER SET 값을 갖게 된다. SELECT가 안 되면 ROLLBACK
하고 UPDATE부터 다시 하도록 한다.
2. 환경 변수 NLS_LANG 을 변경한다.
.profile 에서
NLS_LANG=American_America.KO16KSC5601; export NLS_LANG
또는 .cshrc 에서.
setenv NLS_LANG American_America.KO16KSC5601
*** win95 및 winnt의 client에서는 registry editor에서 NLS_LANG 값을
맞추어준다.
주의 !!!
: 위의 작업을 하기 전에 발생할 가능성이 있는 문제점
1) update 중 KO16KSC5601 이나 US7ASCII 등에서 철자를 잘못 입력하시면,
db 재기동 후에, 다음과 같은 에러가 발생합니다.
ora-12708
12708, 00000, "error while loading create database NLS parameter %s"
2) KO16KSC5601과 US7ASCII의 비교
Character set : KO16KSC5601 인 경우
===================================
: double byte encoding schema 이므로, 한글의 경우 2 bytes 를 크기 1로
계산하는 함수들이 있습니다.
그리고, table , column name에 한글을 double quote 없이 사용할 수 있습니다.
예)
SQL> create table 시험1
2 (컬럼1 varchar(10));
가
a
홍길동
SQL> select length(컬럼1) from 시험1;
1
1
3
SQL> select lengthb(컬럼1) from 시험1;
2
1
6
Character set : US7ASCII 인 경우
=================================
: single byte 7 bit encoding 을 사용합니다.
한글로 된 table, column 이름 사용 시 double quote를 반드시 사용해야 한다.
예)
SQL> create table "사원"
2 ("사원이름" varchar2(10));
가
a
홍길동
SQL> select length("사원이름") from "사원";
2
1
6
SQL> select lengthb("사원이름") from "사원";
2
1
6
US7ASCII일 때에는 vsize, lengthb function의 결과가 length 함수와 모두
동일합니다.
cf) substr, substrb 함수도 위의 length, lengthb의 관계와 같음.
