Database character set migration rules
We have an application which migrates various entities from one database to the other. These databases could have different character sets. The migration process is automated. What character set rules should we follow while migration? Can we use the character set scanner is some automated way?
Does ORACLE publish a comprehensive list of subsets and supersets? (and I am NOT talking about strict subsets and supersets) I know that you have a whitepaper which has some rules but that is not a complete set. Any help would be much appreciated. This is an urgent requirement.
There is no simple answer as this is a complex process. You make reference to having looked at a whitepaper on this subject so I assume you know that your application will likely need to dynamically set the nls_lang setting so that proper conversion can take place on the database.
To find what character sets are subsets or supersets of what character sets?
A) The only listing available is in the 8.1.7 Document addendum shipped with the rdbms CD. This document can be found on the web at:
http://technet.oracle.com/docs/products/oracle8i/doc_index.htm
There is no real elegant way to determine possible lossy data situations programmically. Using the scanner to detect within your program whether proper conversion will take place might be possible. There is a documented v$ table that is updated when the scanner is run that could be examined
via SQL in your program to detect lossy data and truncation. You could also possibly use the PL/SQL convert function to detect lossy data. Something like if 'string' = convert('string', us7ascii, WE8MSWIN1252) then ....
Hope this helps.

New white paper: Character Set Migration Best Practices
This paper can be found on the Globalization Home Page at:
http://technet.oracle.com/tech/globalization/pdf/mwp.pdf
This paper outlines the best practices for database character set
migration that has been utilized on behalf of hundreds of customers
successfully. Following these methods will help determine what
strategies are best suited for your environment and will help minimize
risk and downtime. This paper also highlights migration to Unicode.
Many customers today are finding Unicode to be essential to supporting
their global businesses.Sorry about that. I posted that too soon. It should become available today (Monday Aug 22nd).

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 review implication of database character set change on PL/SQL code?
Hi,
We are converting WE8ISO8859P1 oracle db characterset to AL32UTF8. Before conversion, i want to check implication on PL/SQL code for byte based SQL functions.
What all points to consider while checking implications on PL/SQL code?
I could find 3 methods on google surfing, SUBSTRB, LENGTHB, INSTRB. What do I check if these methods are used in PL/SQL code?
What do we check if SUBSTR and LENGTH functions are being used in PL/SQl code?
What all other methods should I check?
What do I check in PL/SQL if varchar and char type declarations exist in code?
How do i check implication of database characterset change to AL32UTF8 for byte bases SQL function.
Thanks in Advance.
Regards,
RashmiThere is no quick answer. Generally, the problem with PL/SQL code is that once you migrate from a single-byte character set (like WE8ISO8859P1) to a multibyte character set (like AL32UTF8), you can no longer assume that one character is one byte. Traditionally, column and PL/SQL variable lengths are expressed in bytes. Therefore, the same string of Western European accented letters may no longer fit into a column or variable after migration, as it may now be longer than the old limit (2 bytes per accented letter compared to 1 byte previously). Depending on how you dealt with column lengths during the migration, for example, if you migrated them to character length semantics, and depending on how relevant columns were declared (%TYPE vs explicit size), you may need to adjust maximum lengths of variables to accommodate longer strings.
The use of SUBSTR, INSTR, and LENGTH and their byte equivalents needs to be reviewed. You need to understand what the functions are used for. If the SUBSTR function is used to truncate a string to a maximum length of a variable, you may need to change it to SUBSTRB, if the variable's length constraint is still declared in bytes. However, if the variable's maximum length is now expressed in characters, SUBSTR needs to be used. However, if SUBSTR is used to extract a functional part of a string (e.g. during parsing), possibly based on result from INSTR, then you should use SUBSTR and INSTR independently of the database character set -- characters matter here, not bytes. On the other hand, if SUBSTR is used to extract a field in a SQL*Loader-like fixed-format input file (e.g. read with UTL_FILE), you may need to standardize on SUBSTRB to make sure that fields are extracted correctly based on defined byte boundaries.
As you see, there is universal recipe on handling these functions. Their use needs to be reviewed and understood and it should be decided if they are fine as-is or if they need to be replaced with other forms.

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,

Clarification on Character set migration from US7ASCII to UTF8
Hi,
I need clarification on the below.
I need to migrate the database from US7ASCII to UTF8.
For this I ran csscan for user "TEST" as well as against full database.
Below log is the csscan output against full database. but my application is depended on TEST schema only. Shall I need to migrate SYS objects data as shown below or it's not required?. If required how to migrate these objects data?
Looking forward you help.
USER.TABLE Convertible Exceptional
SYS.METASTYLESHEET 58 TEST.Table_1 9 0
TEST.Table_2 11 0
TEST.Table_3 17 0
TEST.Table_4 11 0
[Distribution of Convertible Data per Column]
USER.TABLE|COLUMN Convertible Exceptional
SYS.METASTYLESHEET|STYLESHEET 58 0
Thanks,
SankarI think you need to migrate all schemas data not only one application schema because
the database character set is common to all CHAR, VARCHAR2, LONG and CLOB colums
for any tables in any schema.
In your case (US7ASCII to UTF8), you need to use export/import because:
Another restriction of the ALTER DATABASE CHARACTER SET statement is that it can be used only when the character set migration is between two single-byte character sets or between two multibyte character sets. If the planned character set migration is from a single-byte character set to a multibyte character set, then use the Export and Import utilities.

Arabic text shows junk in database character set
Hi,
Workion EBS Ver11.5.0
NLS_CHARACTERSET :AR8ISO8859P6
NLS_LANG : AMERICAN_AMERICA.WE8ISO8859P1
i have a trial balance report, in that description text is displaying like this ????? ??? ?????? - ???? ????? ???
to rectify this, what steps should i do to display in arabic text and it should support both arabic and english.
could anyone please help me in this.
Thanks and Regards
KhaleelFirst you should make sure your client machine is able to display arabic data.
Second you likely need to change NLS_LANG character set part to the right character set, possibly AR8ISO8859P6 or another character set compatible with your database character set.
Please read carefully OTN NLS_FAQ http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm.
If you are working with Oracle E-Businees Suite, there may be some additional rules to configure application server to display correctly arabic data. -

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
ThanksYou 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. -

You can create the database with WE8DEC character set
and to use the WE8ISO8859P9 on the client or even on Linux.
The NLS_LANG setting doesn't effect the database, but the
interface with the database. The same setting can be used in de
windows 95/98/NT registry.

ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 1
Why does it mention UCS2, as can't see that on the Database character set?
Many thanks for your help,
MarkUSC2 is known as AL16UTF16(LE/BE) by Oracle...
Try using AL32UTF8 as the character set name
AFAIK The main difference between Oracle's UTF8 and AL32UTF8 character set is that is the UTF8 character set does not support those UTF-8 characteres that require 4 bytes..
