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

How to change the database character set on physical standby database?

Hi,
We have a database with character set WE8ISO8859P1 and migrated the character set to WE8MSWIN1252 using csscan/csalter scripts. This database has a physical standby database setup also and after the migration, the physical standby database is still showing the character set as WE8ISO8859P1. How can I change the characterset on the physical standby? I raised a Service Request with Oracle, and they said that recreating the standby database is the only supported way of changing the char set on the standby database. Is this true?
Thanks,
Sreekanth

Thank you, Robert, for your reply.
The standby is in sync with the primary.
see below
SYS@sisprod>select * from v$dataguard_stats;
NAME VALUE UNIT TIME_COMPUTED
apply finish time +00 00:00:00.0 day(2) to second(1) interval 12-NOV-2009 14:02:46
apply lag +00 00:00:00 day(2) to second(0) interval 12-NOV-2009 14:02:46
estimated startup time 11 second 12-NOV-2009 14:02:46
standby has been open N 12-NOV-2009 14:02:46
transport lag +00 00:00:00 day(2) to second(0) interval 12-NOV-2009 14:02:46

I am selecting from v$nls_parameters;
I don't know how to restore the controlfile from primary. Could you please tell me how to do it?

How to change the database character set?

Hi,
We have installed jboss turkey with MySQL and we want to prepopulate name fields like with data from the database in multilingual enviroments i.e. greek,english and russian e.t.c.Where and how can we change that?

I'm not sure, but in other environments, you have to change your JDBC settings.
So, this must be in (imho) C:\Adobe\LiveCycle8\jboss\server\all\deploy\adobe-ds.xml
          IDP_DS
          jdbc:mysql://localhost:3306/adobe
          com.mysql.jdbc.Driver
          adobe
          INSTALLER
          1
          100
          20000
          10
          50
          TRANSACTION_READ_COMMITTED
I would change the
jdbc:mysql://localhost:3306/adobe
to
jdbc:mysql://localhost:3306/adobe?charSET=YOURCHARSETHERE
That's the way I do it in other jdbc connections, so I think this will work here too ...

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.

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.

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.

Approach to converting database character set from Western European to Unicode

Hi All,
EBS:12.2.4 upgraded
O/S: Red Hat Linux
I am looking for the below information. If anyone could help provide would be great!
INFORMATION NEEDED: Approach to converting database character set from Western European to Unicode for source systems with large data exceptions
DETAIL: We are looking to convert Oracle EBS database character set from Western European to Unicode to support Kanji characters. Our scan results show
both “lossy (110K approx.)” and “truncation (26K approx.)” exceptions in the database which needs to be fixed before the database is converted to Unicode.
Oracle Support has suggested to fix all open and closed transactions in the source Production instance using forms and scripts.
We’re looking for information/creative approaches who have performed similar exercises without having to manipulate data in the source instance.
Any help in this regard would be greatly appreciated!
Thanks for yourn time!
Regards,

There are two aspects here:
1. Why do you have such large number of lossy characters? Is this data coming from some very old eBS release, i.e. from before the times of the Java applet interface to Oracle Forms? Have you analyzed the nature of this lossy data?
2. There is no easy way around truncation issues as you cannot modify eBS metadata (make columns wider). You must shorten or remove the data manually through the documented eBS interfaces. eBS does not support direct manipulation of data in the database due to complex consistency rules enforced by the application itself (e.g. forms).
Thanks,
Sergiusz

Need to change character set from WE8MSWIN1252 to AL32UTF8.

We have installed the database with Character set WE8MSWIN1252. But off late we understood that client requirement is AL32UTF8. Is there any way to change in easy method?
Thanks in-advance.

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

Can we change the DB character set at session level

hi,
Please help me
when iam giving the alter session command iam getting the error:
SQL> ALTER SESSION set NLS_CHARACTERSE
T =WE8MSWIN1252;
ALTER SESSION set NLS_CHARACTERSET =WE8MSWIN1252
ERROR at line 1:
ORA-00922: missing or invalid
i need to enter Arabic names in using the xml file.
here i have two questions
1)is it is possible to set character set at session level. because my client is not allowing to bounce the database. DB version is 10.2.0.4
Right now my DB is in US7ascii
2)is this "WE8MSWIN1252" set supports Arabic.
Regards,
Naresh

You cannot change the characterset at the session level. If you want to store ARABIC characters in your database then you should change the characterset of your database to any other characterset that supports Arabic characters or to a Unicode characterset like UTF8 or AL32UTF8.
If you try to insert Arabic characters with your present US7ASCII charancterset then the characters would be stored as junk.

How to change the maximum character setting for password in firefox

i have a long password about 18 character to open an application from my desktop , but I cannot type in the 18 character password on my laptop using firefox browser. Is urgent can please help?

You can try to increase the maxlength by running this code in the Scratchpad (Web Developer > Scratchpad;Shift+F4) or the command line of the Web Console (Web Developer > Web Console;Shift+Ctrl+K), but the server may not accept it.
*https://developer.mozilla.org/en/Tools/Scratchpad

<pre><nowiki>N=document.querySelectorAll('input[maxlength]'),I;

How do i change the default character set?

I'm from Brazil, and here we have special characters like "�", "�", "�", etc.
I need the JVM to understand that from the database and print it correctly on my page (I'm using servlets).
How do i do that?
thanks to all.

java works just fine with Brazilian characters....I
should know I developed software for a brazilian
company for the last 5 years using java.
Ok. I believe you do. I just wanna know how. i'm using servlets. So, to print out the page, i use.
PrintWriter out = response.getWriter();
out.println("some_text");
out.println(resultset.getString("some_field"));
If "some_text" contains special characters, they are printed correctly. No problem about that.
the problem is when the string from the database/resultset has special characters. Those aren't printed correctly. And that's what i want to fix.
Any suggestions?

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.

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 ->
