• Changing the character set in the database 11G

  Running Windows 2008 Server 64-bit and Oracle 11 g (V 11.2.0.1.0). I would like to change my default character set when installing from 11 G to CS AL32UTF8.
  
  I read the utility Guide and Guide Support for globalization (http://docs.oracle.com/cd/B28359_01/server.111/b28298/ch11charsetmig.htm#g1011430), but none of these documents shows how you can effectively change everything / the character set of the migration. I would do this using the export and import utilities since this seems to be the most popular recommendation. But I'm really not sure of the procedure to follow to change the CS. For example, should I first export and then import then run the CSCHANGE script that is described in the globalization support Guide?
  
  I would be grateful any guidance on how to actually change the character set to AL32UTF8 and all documentation that explains not only the concepts, but the STEPS of HOW this can be done. Thank you, J

  It seems that you have an XMLType column based on a pattern of failure revalidation.

  It's strange, but fortunately, the error has nothing to do with the database character set.

  Just change your NLS session parameters:

  ALTER session set nls_numeric_characters = ".";

  and try again.

• Error ORA-12712 when changing the character set AL32UTF8 to nls

  Hello
  
  It is strongly advised to use the AL32UTF8 database character set when ever a database is used with our XML capabilities. The database character set in the installed base is WE8MSWIN1252. To use XML DB functionality, I need to change it to AL32UTF8. But, when I try to do that, I get ORA-12712: new character set must be a superset of the old character set. Is there a way to fix this?
  
  Thanks in advance,
  Divya.

  Hello

  a change of we8mswin1252 to al32utf8 is not directly possible. This is because al32utf is not a binary superset of we8mswin1252.

  There are 2 options:
  -use any export and import
  -Use of the altar in a kind of limited

  Depends on the method, you can choose the characters in the database, is that only ASCII then the other can work, in other cases, one is necessary.

  It is all described in Note 260192.1support, "replacing the NLS_CHARACTERSET AL32UTF8 / UTF8 (Unicode). Get on-site support/metalink.

  You can also read the chapters about it in the Guide of globalization: [url http://download.oracle.com/docs/cd/E11882_01/server.112/e10729/ch11charsetmig.htm#g1011430] change characterset.

• Database character set UTF-8

  Hello

  I get a few knock back of DBA on the sine qua non to create a database of the UTF8 character set, except the fact that the product is not supported, otherwise UTF - 8 are there other known problems with UTF-8, I can cite in support of my case?

  Or are workarounds that Oracle support would be happy with allowing the use of a database not UTF8?

  Thanks for your comments,

  Robert.

  NB: I've seen = > https://blogs.oracle.com/pa/entry/issues_during_configuration_when_using

  Documentation:

  Considerations for creating Oracle database

  The database must be created using Unicode Transformation Format UTF-8 encoding (character set). Oracle supports the following character with the UTF-8 encoding sets:

  • AL32UTF8 (UTF-8 encoding for ASCII platforms)
  • UTF8 (backward compatible coding for Oracle)
  • UTFE (encoding UTF-8 for the EBCDIC platforms)

  If the prerequisites helpful cannot be met then it is between yourself, dba and Oracle support.

  See you soon

• change the character set

  Hi all
  
  We use:
  
  Oracle Application on the Enterprise Linux 4 update 5 AS version 11.5.10.1.
  Version of database is 10.2.0.3 with character EE8MSWIN1250.
  
  We have the plan to migrate from this set of characters Unicode (AL32UTF8).
  Is there something specific in this, or we can just use the standard migration of oracle to the unicode character database.
  
  Do we need to do something on the application tier of the Oracle Applications, or we can simply migrate database to Unicode characters,
  and the app will be good work after the next startup db and app level.

  While installing RCU get an error where it recommends the AL32UTF8 user. How to change the character set.

  You cannot change the character set. You can click on ignore and install UCR in the database not utf8, but Oracle can't stand repository in non utf8 databases.

  It is at your own risk.

• Value US7ASCII AL32UTF8 database character change

  Our database is running on the Oracle 10.1.0.4.0 database (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 value AL32UTF8 database character. After completing the Metalink notes: 260192.1 (who helped us solve data "With" and "Truncated", is the final result of the CSSCAN utility):
  
  [Scanning summary]
  All data type characters in the data dictionary can be convertible to the new character set
  All data of character type is convertible to the new character set
  
  [Summary of the Data Conversion dictionary]
  The data dictionary can be migrated safely using the CSALTER script
  
  We have no truncation and with (0) entry on the .txt file. We have Changeless and Convertible. Now accdg to the documentation, we can do a FULL EXP and FULL IMP. But it does not detail how to do the conversion on the same database. The discussion on the document explains how do from one database to another database. But what about on the same database?
  
  We cannot use CSALTER as indicated on the document.
  (Step 6
  Step 12
  12.c) when you use Csalter/Alter database to AL32UTF8 and there was NO data "Truncation", only "Convertible" and "Changeless" in the csscan in point 4 :)
  
  After you COMPLETE the database export, how can we change its character set? What must we do the existing database to change its character value AL32UTF8 until we import back our in the same dump file database?
  
  Help, please.

  You cannot use CSALTER indeed you have given application convertible. Only the application data does not change are supported by the script.

  We do not support the conversion in place of the version of database you have except via Oracle Consulting services. Please upgrade to one of the versions of database supported by the DMU (http://www.oracle.com/technetwork/database/globalization/dmu/overview/index.html) utility and ask the DB fix required for the enhanced version and platform supported by the Oracle. I think there is already a patch for 10.2.0.5 on AIX 64-bit POWER but this is to be confirmed.

  Without the CDS, you can do a selective export of only convertible tables, truncate table, use CSALTER and re - import.

• Character set of database and the national character set?

  Hi all
  
  I'm sorry if the question is stupid.
  
  why we need a so-called "national character set"?, I think it's important to keep the consistency of the character set, and this thing "national character set" really confuses me.
  
  in my opinion, if you are in English speaking countries, use ASCII coding such as your database character set, if not, just use you UNICODE, everything should be good, why?
  
  Thanks in advance.

  For Oracle Database, database character set is for the data types CHAR, VARCHAR2 and national character set to NCHAR, NVARCHAR2, and NCLOB and CLOB. Please read http://download.oracle.com/docs/cd/E11882_01/server.112/e10729/ch6unicode.htm#CACHCAHF.

• Character set conversion

  Hi all

  I have a 10.2.0.4 database with US7ASCII character set, which contains non-ascii, e.g. 'e' characters (chr (232)).

  Now I would like to upgrade to 11.2 with character WE8ISO8859P15 using expdp/impdp, but these non-ascii characters are not imported correctly. I tried all possible combinations of settings LANG and NLS_LANG (on the exports and imports), but I always chr (191) as a result.

  Is it possible to do the same thing (with, of course, the original values)?

  Operating system is Linux.

  Thanks in advance

  Guido

  Your options:

  1 clone the database and upgrade to 11.2 keeping the current mess. Simple but certainly not recommended.

  2. assuming that you can assign all non-ASCII characters to a set of unique characters, like WE8MSWIN1252, clone the database, upgrade to 11.2 and follow the procedure described in MOS 555823.1 Note to change the character set for this set of unique character. The note is probably a little too complex, but you should get the point. You can also search this forum some of my older replies. I think I described a version shortened the procedure somewhere Note: you will get a database in the character set of the current data, not necessarily WE8ISO8859P15. However, there is no reason to insist on WE8ISO8859P15, unless all clients are on Unix type system and use that character set. If you move only a subset of the data, use of the database migrated in the form described in this point and then run a selective Data Pump to move only the data necessary for your target WE8ISO8859P15 (assuming that it already exists and cannot be recreated in a recommended character set). Note however that WE8MSWIN1252 supports different characters not supported by WE8ISO8859P15, such movement can cause the loss of character.

  3 assuming you can assign all non-ASCII characters to a set of unique characters, like WE8MSWIN1252, clone of the database, upgrade to 11.2.0.4 and use The database for Unicode Migration Wizard to migrate the database to AL32UTF8 (Unicode) in place. The "Supposed Character Set database" property in the digital mock-up allows you specify the data identified unique character set so that CDS not US7ASCII migrate (converted) of all good character,. It is the most complex, but also more forward-looking option.

  Thank you
