How to change Database character set?

Hi,
We are planning to make a clone of production Database which has:
select value$ from sys.props$ where name='NLS_CHARACTERSET';
AL32UTF8
We have set up a new server for that purpose and installed database, but by default it has
select value$ from sys.props$ where name='NLS_CHARACTERSET';
WE8ISO8859P1
So after making full import from full backup file we have some broken character in database.
How can I change from WE8ISO8859P1 to AL32UTF8?
I expect that I need to shutdown the clone database or even make from scratch full import.
Thanks

I made a full backup from production database which has AL32UTF8
My new database is fresh and it has WE8ISO8859P1
I think the reason why I'm having some corrupted characters is because of difference in Character set between two database, right?
so I will need to change new database Character set to AL32UTF8 then make again full import.

How to change the Character Set from AL32UTF8 to WE8DEC

Hello!!
I want to know how to change the character set in the database from AL32UTF8 to WE8DEC.
I tried to use the comand ALTER DATABASE CHARACTER SET but I got an error because WE8DEC is not a superset of AL32UTF8.
I need to import tables from a server that uses WE8DEC. So when I do the import to my server, wich has AL32UTF8 , I can't import the rows that include an Ñ.
So I want to change the caracter set to WE8DEC. How can I do it?
Is it needed to change the language configuration? The remote server has AMERICAN_AMERICA, and my server has MEXICAN SPANISH_MEXICO (both uses text in spanish).
Thanks a lot!!

When you export from WE8DEC server what did you use
for NLS_LANG char set? And when importing?
The export was done in another computer because I can't do the export in the server (I have 10g, and the remote server has 9i and the export is not working). In my server, when I tried to do the import, the NS_LANG value was MEXICAN SPANISH_MEXICO.WE8MSWIN1252.
When I try to import to my database I got the error:
import done in WE8DEC character set and AL16UTF16 NCHAR character set
import server uses AL32UTF8 character set (possible charset conversion)
export client uses WE8MSWIN1252 character set (possible charset conversion)

Changing database character set from US7ASCII to AL32UTF8

Our database is running on Oracle database 10.1.0.4.0 (AIX) The following are its parameters:
SQL> select value from NLS_DATABASE_PARAMETERS where parameter='NLS_CHARACTERSET';
VALUE
US7ASCII
We would like to change the database character set to AL32UTF8. After following Metalink notes: 260192.1 (which helped us resolve "Lossy" and "Truncated" data, the final output of the CSSCAN utility is:
[Scan Summary]
All character type data in the data dictionary are convertible to the new character set
All character type application data are convertible to the new character set
[Data Dictionary Conversion Summary]
The data dictionary can be safely migrated using the CSALTER script
We have no (0) Truncation and Lossy entries on the .txt file. We only have Changeless and Convertible. Now accdg to the documentation, we can do a FULL EXP and FULL IMP. But it did not detail how to do the conversion on the same database. The discussion on the document tells how to do it from one database to another database. But how about on the same database?
We cannot use CSALTER as stated on the document.
(Step 6
Step 12
12.c) When using Csalter/Alter database to go to AL32UTF8 and there was NO "Truncation" data, only "Convertible" and "Changeless" in the csscan done in point 4:)
After performing a FULL export of the database, how can we change its character set? What do we need to do the the existing database to change its character set to AL32UTF8 before we import back our dump file into the same database?
Please help.

There you are! Thanks! Seems like I am right in my understanding about the Oracle Official Documentation. Thanks!
Hmmmmm...when you say:
*"you can do selective export of only convertible tables, truncate the tables, use CSALTER, and re-import."*
This means that:
1. After running csscan on database PROD, i will take note of the convertible tables in the .txt output file.
2. Perform selective EXPORT on PROD (EXP the convertible tables)
3. Truncate the convertible tables on PROD database
4. Use CSALTER on PROD database
5. Re-import the tables into PROD database
6. Housekeeping.
Will you tell me if these steps are the correct one? Based on our scenario: This is what i have understood referring to the Official Doc.
Am i correct?
I really appreciate your help Sergiusz.

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

Change Database Character Set to Arabic!

Dear All,
My database is Oracle 11gR2 On Linux platform.
I am trying to change the character set of my database to store Arabic characters.
This is what I am doing:
SHUTDOWN IMMEDIATE;
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 INTERNAL_USE AR8ISO8859P6;
SHUTDOWN IMMEDIATE;
STARTUP;
When i check:
SQL> select value from NLS_DATABASE_PARAMETERS where parameter='NLS_CHARACTERSET';
VALUE
AR8ISO8859P6
But still when i query data it shows it like this:
"¿¿¿¿¿¿ç ¿¿ê ¿¿¿¿çê¿ ¿¿¿¿ ¿¿¿ ¿¿¿¿¿¿ ¿¿¿¿ ¿¿¿èê¿ ¿¿¿è¿ ¿¿¿¿ê¿¿ ¿¿¿ ¿¿â¿¿ ¿¿é ¿¿¿ è¿¿¿ ¿ê ¿¿¿¿ êè¿ ¿¿¿¿¿¿ 28/9 ¿ê ¿ ¿¿é ¿¿¿¿ ¿è¿¿ê èç¿¿¿ ¿è¿¿¿ âê¿¿ ¿¿¿ è¿¿â¿ ¿¿è¿"
Can you help me to understand where is the problem and how to get through it.
Regards, Imran

Why on earth are you using the undocumented INTERNAL_USE command? The name alone should strongly imply that this isn't something that normal users should be playing with. It is extremely likely that you've corrupted your database.
Do you have a backup of your database taken before you corrupted it? If so, can you restore that backup? Once you do that, tell us what character set you're starting with. If you are implying that there is existing data in the database, what character set is that data encoded with? Can you DUMP the data to verify this?

Changing database character set

Can anyone help with the way to change the database character set.
I am runn into problem while exporting with error message exp-00091
Thanks

You don't need to change the database character set. You have only to set the correct character set at
OS level before doing the export. Execute the following at Sql prompt as DBA :
SQL> select * from v$nls_parameters
2* where parameter in ('NLS_LANGUAGE', 'NLS_TERRITORY', 'NLS_CHARACTERSET')
SQL> /
PARAMETER            VALUE
NLS_LANGUAGE         AMERICAN
NLS_TERRITORY        AMERICA
NLS_CHARACTERSET     WE8ISO8859P15
SQL>then at OS prompt :
$ export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P15
$ exp ..............
Of course you have to use your values.

How to change the character set encoding not being a superset one

HI, i have a fresh installed database, but i realize the character set support in my client is not good enough, since its a not production database i want to change the character set encoding to anothor one not being a superset of the old one.
I have tried the "ALTER DATABASE CHARACTER SET WE8MSWIN1252" but it fails claiming i need a superset one.
I guess its just a single steps to do it, i have all the privileges, just not the time to reinstall and setup everything.

Do you know what that does to the existing data, though? My hunch would be that any characters which have a different binary representation in the source & target character sets would be corrupted.

How to alter database character set from AL32UTF8 to EE8MSWIN1250

Hi folks,
I'm using an Oracle 10g, XE database, which has a database character set set to AL32UTF8, what causes that some characters like "č ť ř ..." are not displayed.
To fix this issue, I would like to change it to EE8MSWIN1250 character set as it's set on server.
Unfortunatelly below steps don;t work for me:
connect sys as sysdba;
SHUTDOWN IMMEDIATE;
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 NATIONAL CHARACTER SET EE8MSWIN1250;
ALTER DATABASE CHARACTER SET EE8MSWIN1250;
SHUTDOWN IMMEDIATE; -- or SHUTDOWN NORMAL;
STARTUP;Value in regedit: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_XE is set to CZECH_CZECH REPUBLIC.EE8MSWIN1250
I'm struggling with this issue for hours and unfortunatelly can't make it work. Any advise is more than welcome.
Thanks,
Tomas
I tried to use hints listed here , but always getting some ORA messages.

Hi Sergiusz,
Thank you for your reply. You're right, I've probably didn't provide a full details about my issue, but at least now I know, that database encoding(characterset) is correct.
Here is my issue:
Within my APEX application I would like to use a JasperReportsIntegration, so to be able to create and run iReports straight from APEX application. Installation, and implementation of JasperReports works fine, I had no issue with it.
As a second step I've created a simple report using iReport tool, when if preview function is used, all static characters (from report labels) are displayed correctly. Database items are displayed incorectly - some Czech characters are not displayed. Language within report is set to cs_CS, but I've tried also other options. No sucess.
When I run that report from APEX application (from server) then the same issue - data from database are returned without some czech characters.
Kind regards,
Tomas

Oracle 11g Installation How to select Database Character Set

Hi,
I am Installing oracle 11g R2. After installation I had verified the character set it was AL16UTF16 but I wants to set AL32UTF8 charater set at the time of oracle installation only. I can't see the character set setting opetion at the time of installation because I am selecting the installation option " Install database softerware only" and after installation of oracle software manually I am creating the database. Please help me how can I set the character set at the time of oracle installation or at the time of database creation.
My question is-
How can I set the AL32UTF8 character set in above scenario?
Why It is showing AL16UTF16 character set even I did not define any thing?

But is there any choice to set the NLS_CHARACTERSET at the time of manually database creation. Actually For creating the database i am using one shell script for seting the parameter values in init.ora file so can I set the parameter at that level(at the time of creating init.ora using manually database creation). like

How to change the character set?

Platform is win2000 and oracle 8.17. I need to write data in Bulragian. Automatic character converter in oracle didn't work! Database is created already!
Is there any function in pl/sql or Java that can convert character set in cl8mswin1251? When I read the data from database there are only ?????
Thank you in advance!

I'm not sure what you're asking here. "Will it be ok" for what?
Assuming
- you read the chapter I linked to,
- ran the character set scanner,
- the character set scanner indicated that all your existing data is properly encoded ISO 8859-1
- the character set scanner indicated that all the ISO 8859-1 data could be converted to Windows-1252
- all the national character set data was properly encoded in whatever national character set the database had
- you did the export properly
- you did the import properly
- your client NLS_LANG settings are all correct
then sure, everything should be OK.
If you skipped one of these steps, I would again strongly encourage you to read the chapter I linked to originally as well as the Metalink article others have pointed you to.

Hi ,

Change existing character set

Hi All,
I want to change current character set of my DB.
My DB version is 8.1.7 and character set is US7ASCII.
This character set does not support to store Euro symbol (â¬). So I want to change to another charset.
Currently I also have another DB, version 9.2.0 and charset is AL32UTF8 and National charset is AL16UTF16. This charset supports â¬ symbol.
But when I tried change chatset of 8i US7ASCII to AL32UTF8, an error happened: "ORA-12712 new character set must be a supersetof old character set".
Character set WE8ISO8859P1 support â¬ symbol.
I tried to change character set of 8i from US7ASCII to WE8ISO8859P1 successfully but change character set of 9i from AL32UTF8 to WE8ISO8859P1 unsuccessfully, error is "ORA-12712 new character set must be a supersetof old character set".
Please let me know which character set is superset of US7ASCII and AL32UTF8.
I want to change character set of 8i and 9i to the same another character set that support â¬ symbol.
Thanks in advanced,
Thi Nguyen
