Migratiom from WE8MSWIN1252 to al32utf8

Hi
I need to migrate my db from western Europe character set to a multi byte character set.
I exported my data from 10g instance with WE8MSWIN1252 and then imported it to an 10g instance with AL32UTF8 and nsl_lenght_semantic = 'CHAR'.
The VARCHAR2 fields and char fields are still defined as bytes.
es. my_desc varchar2(100 byte )
Then I need to convert all varchars and char fields definition to 'CHAR'.
I know that I can perform this field by field using ALTER TABLE MODIFY.
All my tables are defined into one schema, (mySchema.tab1, mySchema.tab2,...).
so, I want to know if it is possible to do this conversion in one step?
Thanks
Mario

es. my_desc varchar2(100 byte )Check your export dump. It could be that create statements etc. are using column length specified as 'byte'.
Metalink/MOS might have some Note that documents possible supported workarounds.

Unable to migrate table, character set from WE8MSWIN1252 to AL32UTF8

Hi,
On our source db the character set is AL32UTF8
On our own db, we used the default character set of WE8MSWIN1252 .
When migrating one of the table, we get an error of this: ORA-29275: partial multibyte character
So in to alter our character set from WE8MSWIN1252 to AL32UTF8, we get this error:
ALTER DATABASE CHARACTER SET AL32UTF8
ERROR at line 1:
ORA-12712: new character set must be a superset of old character set
I would sure not like to reinstall the db and migrate the tables again. Thanks.

See this related thread - Re: Want to change characterset of DB
You can use the ALTER DATABASE CHARACTER SET command in very few cases. You will most likely have to recreate the database and re-migrate the data.

Change Oracle XE from WE8MSWIN1252 to AL32UTF8

I want to change the character set of Oracle XE 10g on my machine from WE8MSWIN1252 to AL32UTF8. I understand I need to scan, change my NLS_LANG and export and them import into new XE with Universal character set.
I need some more details to these steps if someone can help out.
My current Oracle XE details:
NLS_LANGUAGE - AMERICAN
NLS_TERRITORY - AMERICA
NLS_CHARACTERSET - WE8MSWIN1252
I want NLS_CHARACTERSET to be AL32UTF8.
Thanks,

Hi everbody,
Really OracleXE dont suport character convertion.
But I get the binary CSSCAN from another Oracle 10g Enterprise and copy to server of XE in $ORACLE_HOME/bin.
With this, I copy also CSALTER.PLB and CSMINST.SQL to ?/rdbms/admin and now, I have the scripts.
So, I run following the "howto" and read .log, .err and .out files generated from log=
If you receive the message "Checking or Converting phrase did not finish successfully", check the .err file and drop the tables listed as "with error". After this, the process run without erros and YES, the database is CHANGED.
I do this and I can afirm: this process works!

CSSCAN in 11g - Characterset not changing from WE8IMSWIN1252 to AL32UTF8

All,
We have installed a 11g database in Linux box and once after that we wanted to change the character set to AL32UTF8 from default WE8MSWIN1252.
We took the cs-alter approach and ran cs-scan utility, upon going through csscan.txt files generated by csscan utility we found that there are no lossy data but convertible data was found in data dictionary. Below is the output from csscan.txt
This is the Scan Summary
*[Scan Summary]*
All character type data in the data dictionary are convertible to the new character set

But while running csalter.plb csalter came out without changing the characterset. We ran the following query given the said document and it returned no rows which again confirms there is no problem and go ahead with running csalter.

You have convertible data in the application tables. CLOB or not, such data prevents csalter.plb from changing the character set.
You are on 11.2.0.3, so use the DMU (http://www.oracle.com/technetwork/products/globalization/dmu/overview/index.html). It can cope with such data.

Changing Character Set from AL16UTF16 to AL32UTF8

Hi,
I am stuck with a requirement to change the Character Set from AL16UTF16 to AL32UTF8.
I am trying to install the Oracle Content Database & the installer expects the target database to have a Character Set of AL32UTF8. The current Character Set of the Database is AL16UTF16. I am unable to change the Character set as it simply complains that AL32UTF8 is not a super-set of AL16UTF16.The documents that I have consulted mention that such a transitionis not recommended.
How do I convince the installer to continue the installation with AL16UTF16 ? Or, is it possile at all to change the Character Set from AL16UTF16 to AL32UTF8 ?
Please do let me know your thoughts on this.
Regards,
Sandeep

Is your data size above GBs? If not this might help before installation I guess ->

Characterset change from WE8ISO8859P1 to AL32UTF8

Hi,
I have restore the rman on new server oracle 11.2.0.3 (Previous backup was of oracle 10.2.0.4).
Then I have successfully upgrade the database to oracle 11g but issue which I am facing right now is that the old database have the character set WE8ISO8859P1 which is now upgraded to oracle 11.2.0.3 database server.
My required character set is AL32UTF32.
Now is there any way that while restoring the rman backup of oracle 10.2.0.4 on new server I set the character set to AL32UTF32.
Thank you for your cooperation.
Kind Regards,
Adnan Hamdussalam

It means that either I have to change it before backup or after perform the full upgrade on new server oracle 11g and then convert the character set. Am I right?Yes, You are right.
I think as you are changing from WE8ISO8859P1 to AL32UTF8, so you do not need any tool.
Must read note,

Changing the Database Character Set From WE8MSWIN1252 to AR8MSWIN1256

good morning everybody,
I need your help to know all step which it is necessary to follow to change the Database Character Set From WE8MSWIN1252 to AR8MSWIN1256
thank you

If you have not already done so, read up on Character Set Migration and using the CSSCAN tool to verify the database before making any changes.

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.

Running instances with different character set WE8MSWIN1252 and AL32UTF8

We have db instances running AL32UTF8 character set and our applications are built around it, however we have request to create instances using WE8MSWIN1252 character set for another application without bringing in new h/w (server).
what are the ways to implement it?
Edited by: raygear on Aug 23, 2012 7:06 PM

What is the problem? Run DBCA in the advanced mode and specify the required database character set for the new database.

Some Arabic Characters missing thru dblink from AR8ISO8859P6 to AL32UTF8

Hello all,
we have two databases, one with AR8ISO8859P6 character set, and the other is AL32UTF8. When we try to access the value of the former database from the AL32UTF8, some of the arabic characters are shown as reversed question marks. If anybody knows a fix, or, workaround , please let me know

Hello,
Are you using AL32UTF8 for the PlsqlNLSLanguage parameter in your DAD?

Absolutely the INCORRECT thing to do !!
This will result in corruption of your database that you cannot recover from.
