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?

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

Query distributed database with different character sets.

Hello experts, this is my situation:
I have two databases A and B, the same version 11.1.0.7, the same OS Suse Linux Enterprise 10 but with different character sets, A has WE8MSWIN1252 while B has AL32UTF8. The database B is my XML DB repository so there I have some XML type tables. I need to query this tables from the database A using a dblink and in fact I have done that but the XML content is trasformed due to the different character sets between the databases. Some time there are data loss and some time there are data missmatch.
Is there any way to query the tables stored in the database B without problems? I do not know if the following is correct: Maybe I can set the character set for the session in the database A during the time it query the database B. That is, change the character set in fly at session level.
Do you have any special suggestion?
I hope you can help me, thank you in advance.

The Globalization Support Guide for 11.1.0.7 has a chapter on character set migration that should be helpful. AL32UTF8 is a superset of WE8MSWIN1252 but it is not a strict superset. That is, it doesn't meet the second prong of the test in the documentation
The new character set is a strict superset of the current character set if:
Each and every character in the current character set is available in the new character set.
Each and every character in the current character set has the same code point value in the new character set. For example, many character sets are strict supersets of US7ASCII.Exporting the data from the A, changing the character set (or creating a new database with the AL32UTF8 character set), and then importing the data may be the easiest approach in your case.

Searching with different character sets

Hello,
we have a problem with Intermedia 8.1.6. running on Solaris.
The table contains the text with different character sets and that's the problem. User submits the query in his char.set and the IM sometimes doesn't find the data.
Idea is to create the index using the flat ascii chars and to search in ascii ... but how?
Can anybody help me?
Thanks.

NLS settings for a database link between DBs with different character sets

I am using a database link to move data from one database to another and I am seeing some strange data problems. The databases have different character sets and different NLS settings. I wonder if this could be causing my problem.
Here are the NLS parameters for the database where the database link exists. (the SOURCE database)
1     NLS_CALENDAR     GREGORIAN
2     NLS_CHARACTERSET     WE8MSWIN1252
3     NLS_COMP     BINARY

12     NLS_NCHAR_CONV_EXCP     FALSE
13     NLS_NUMERIC_CHARACTERS     .,
14     NLS_SORT     BINARY

18     NLS_TIME_FORMAT     HH.MI.SSXFF AM
19     NLS_TIME_TZ_FORMAT     HH.MI.SSXFF AM TZR
Here are the NLS parameters for the database that the database link connects to. (the TARGET database)
1     NLS_CALENDAR     GREGORIAN
2     NLS_CHARACTERSET     AL32UTF8
3     NLS_COMP     BINARY

The SOURCE database version is 10g Release 10.2.0.3.0 - Production
The TARGET database version is 11g Release 11.1.0.6.0 - 64bit Production
Do I need to modify the NLS settings in the SOURCE database before executing a script to insert data into the TARGET database?
Thanks, Jack

The difference in settings is not a problem by itself, especially that only the NLS_CHARACTERSET matters. Of course, this difference may lead to certain issues if not taken into consideration.
Please, describe symptoms of your problems.

Migrating from 8.1.7 to 9.2 with different character set

Are there going to be issues when I try to migrate from 8.1.7 to 9.2 where the character set in the 8i database was the default western european to utf8 in 9i?
I ran the 8i scan utility to see if there would be issues importing into an 8i db with a different char set and it said that there would.

Hi Jim,
As your first step, I would recommend reading the white paper Character Set Migration Best Practices for Oracle9i on the Globalization Support Home page - http://otn.oracle.com/tech/globalization/index.html
Since you mentioned that CSSCAN has already reported there are potential issues (I guess you have exceptional/Lossy data ?), I would strongly recommend splitting up the UTF8 character set change and the database version upgrade into 2 distant phrases. Probably moving to UTF8 in 8.1.7 first, then upgrading to 9.2 later.
BTW, there is a separate Globlization Support and NLS discussion forum on OTN for further discussion on character set related issues.

Transport tablespaces between databases with different character sets

Hi everyone:
I have two 10R2 databases on the same hp-ux 64bit server, 1st one with NLS_CHARACTERSET=US7ASCII, 2nd one with
NLS_CHARACTERSET=AL32UTF8.
NLS_NCHAR_CHARACTERSET on both databases is AL16UTF16.
Can I transfer tablespaces from the 1st one to the 2nd. The data could be in English, French & Spanish.
If not what are my options?
Thanks in advance.

First off, if you are storing French and Spanish data in database 1 where the character set is US7ASCII, you've got some serious problems. US7ASCII doesn't support non-English characters (accents, tildes, etc). If you're storing data this way, you've introduced data corruption that you'd have to resolve before copying the data data over to another machine.
Second, technically, the source and target character set have to be identical. Since US7ASCII is a strict binary superset of AL32UTF8, you could theoretically transport a US7ASCII tablespace to an AL32UTF8 database. In your case, though, since the data is not really US7ASCII, you'd end up with corruption.
Any of the Oracle built-in replication options is going to require that you resolve the corruption issue. Assuming that you can figure out what character set the source database really is, you could potentially dump the data to flat files (taking care not to allow character set conversion to take place) and SQL*Loader them into the destination system by identifying the proper character set in your control file. That's obviously going to be a rather laborious process, though.

Issue with MView betweem DB's with different character sets

source system is char set IS0-8859-15.
BUT - there is some data in the db that is outside the range of ISO - values are between 128 and 159 decimal. - The data is valid in teh Windows-1252 charset but its not valid ISO.
target is utf-8
Current issue is value in source system is 232 (x84). Thiis is lower double quotation mark, but not valid iso character.
After mview replicates the value, it is xC284. This is not a valid utf8 encoded value.
Correct value in utf-8 would be xE2809E (unicode 201E).
Any suggestions on how to get the mviuew to recognize windows-1252 characters, even though the charset of the database is iso?

Different Character sets?

Oracle version: 11.1.0.7.0
There are any problems if I configure an Oracle Streams Replication between to database with different character set? I have configured a propagation between two database A and B. The A character set is WE8MSWIN1252 and the B character set is WEISO8859P1 but when the propagation passes about 30 minutes configured and ora-07445 begin. Also when I do the same configuration between two database with the same character set the problems does not appear.
Here I write the error in the alert log:

Where did I said that charset is interfering in propogataion? It will not interfere. Char set difference will cause the target database populated with data which it may not understand and will show you as garbage data. As you replication is working find without an issue for sometime, so it looks like you are hitting some bug when you hit replication for some specific data. To confirm this you may have to work with Oracle to find the exact cause or which bug you may be hitting.
All my suggestions till this point in time is without knowing your proper environment (Server A,B OS and database version, also the error description except english words are all foreign to me). As suggested you will be better off working with Oracle support to find the resolution. Please let us know what fixed your issue when you work with Oracle to help all forum members.

Different Character sets (Codepages) in the same Login

Hi,
I need to enter different character sets (Russian and English) in the same login and save the different characters to SAP database tables.
The codepage for Russian is different from English codepage. I have Russian codepage language settings on both Windows and SAP. Can anybody let me know how to proceed with this.
Any pointers on this would be really helpful.
Thanks and Regards,

Different character sets on database links

Does someone know, how to select data from different machines with different character sets via database link transferring the umlauts correctly ?
The destination instance uses we8iso8859p1, the source machines have us7ascii (SAP) or we8iso8859p1. It is NOT allowed to change the character sets on the source databases!

This is not so easy to solve. The correct procedure is to fix your non-ASCII database to reflect the correct character set encoding of your data. Have you checked with SAP to see whether it is really not possible/supported to change the application db character set ?
The only workaround that I can think of ,is to create another database with 'WE8ISO8859P1' as the db character set. Populate it with the data you need from your SAP database using either SQL*LOADER or from insert statements generated by SPOOLing out the data using SQL*PLUS

Expdp with network_link and different character sets for source and target?

DB versions 10.2 and 10.1
Is there any limitation for implementing expdp with network_link but target and source have different character sets?
I tried with many combinations, but only had success when target and source have the same character sets. In other combinations there was invalid character set conversion (loose of some characters in VARCHAR2 and CLOB fields).
I didn't find anything on the internet, forums or Oracle documentation. There was only limitation for transportable tablespace mode export (Database Utilities).
Thanks

Hi DBA-One
This link
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14215/dp_overview.htm#CEGFCFFI
is from Database Utilities 10g Release 2 (10.2) (I read it many times)
There is only one thing about different character sets.
I quote:
Data Pump supports character set conversion for both direct path and external tables. Most of the restrictions that exist for character set conversions in the original Import utility do not apply to Data Pump. The one case in which character set conversions are not supported under the Data Pump is when using transportable tablespaces.
Parameter VERSION also doesn't play role here, because the behaviour (character set) is the same if I use for target and source only 10.2 or (10.2 and 10.1) respectivly.

Multiple oracle database instances with different characterset on the same server

Hello,
Is it possible to have 2 database instances running with different charactersets,one with AL32UTF8 and the other with WE8MSWIN1252.?
Are there any setup requirements to be performed prior to setting up the database instances?
The 3rd party utility that we want to use does not support AL32UTF8 and insists on using a database with character set WE8MSWIN1252.
Kindly help.
Thanks,
Ram.

Hello Zhe,
I guess I posted my question in a wrong forum. I tried my best to find a suitable forum and thought this was the best and closest I found. Apparently not. Can you please let me know the right forum for my question?
The below is the breif of what we are currently facing:
We are in the process of finalizing plans to install Automic for our Retail applications to schedule jobs. In the process came to know that Automic does not support AL32UTF8.
Right now we have RMS and UC4 (now called Automic) run on the database server as UC4 supports AL32UTF8 and schema for UC4 is inside the RMS database.
Going forward it is recommended to have a separate database instance on the same server as that of RMS database and with a different characterset which is WE8MSWIN1252.
Please let me know what forum to post in, I will repost the question.
Thanks,
Ram.

ORA-04062 error when running forms with different users

ORA-04062 error when running forms with different users
I have a form that has a block that should display some data from another users tables. (The other user's name is dynamic, it's selected from a list box)
I wrote a stored procedure to get the data from other user's tables.
When I compile the form and run it with the same user I compiled, it works without any error. But when I run the compiled form with another user I get the ORA-04062 (signature of procedure has been changed) error.
I tried setting REMOTE_DEPENDENCIES_MODE to SIGNATURE in init.ora but it didn't help.
My Forms version is 6i with Patch 15.
Database version is 9.
Here is my stored procedure:
TYPE Scenario_Tab IS TABLE OF NUMBER(34) INDEX BY BINARY INTEGER;
TYPE Open_Curs IS REF CURSOR;
PROCEDURE Get_Scenarios(User_Name IN VARCHAR2, Scen_Table OUT Scenario_Tab) IS
Curs Open_Curs;
i NUMBER;
BEGIN
OPEN Curs FOR
'SELECT Seq_No FROM '|| User_Name ||'.scenario';
i := 1;
LOOP
FETCH Curs INTO Scen_Table(i);
EXIT WHEN Curs%NOTFOUND;
i := i + 1;
END LOOP;
END Get_Senarios;
I would be happy to solve this problem. It's really important.
Maybe somebody can tell me another way to do what I want to do. (getting a list of values from another users tables)

I think it should be a better solution to create a package,
and put your own TYPES and procedure into it.
CREATE OR REPLACE PACKAGE PKG_XXX IS
TYPE TYP_TAB_CHAR IS TABLE OF .... ;
PROCEDURE P_XX ( Var1 IN VARCHAR2, var2 IN OUT TYP_TAB_CHAR );
END ;
Then in your Form :
Declare
var PKG_XXX.TYP_TAB_CHAR ;
Begin
PKG_XXX.P_XX( 'user_name', var ) ;
End ;

How to include different Character Sets in Flex AIR project

Hi All,
Flex, AIR(Desktop) Project.
PROBLEM Scenario:
My Application needs a path from Windows registry, So I am launching a .cmd file using Native Process API.
As a result I get a text file with the path.
So, everything works fine(reading/writing), but if the path contains different languages like Korean, Chinese then the READING OPERATION IS FAILED only when I install the application. It works fine while debugging.
(By failing I mean its not getting the characters, its printing some junk values.)
I am using readMultibyte & writeMultibyte APIs, and I am assiging the character set dynamically as per the OS language. (Which is Enslish in current scenario)
FINDING:
I installed Windows with Korean Language on a system, so now if I build the .exe on this machine then it works fine. So, i guess its not able to get the Korean Character set from the English OS, thats why it failed in earlier case.
Is there any way to include different character sets in a Flex project?
Regards,
Mayank

Some loaded SWFs may not be compatible with Flex. Try making a simpler SWF (like one that just draws a circle where you click) and see if it can be loaded and interacted with.
