Re: Another Character Set Problem
To change the character set to another that is not recognized as a superset use: Alter database db-name character set INTERNAL_USE new_character_set This parameter is active for oracle 8.1 and above. Yechiel Adar Mehish - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, September 12, 2002 3:18 PM We are currently having a character set problem. We have a third-party product that is used for on-line courses (Prometheus from Blackboard, Inc.). The character set that the instance was created with was US7ASCII. The vendor says it should be WE8ISO8859P1, but we need to support Chinese and Japanese characters. I contacted Oracle support, and was told that the specified character set would not support those characters, but that I should use UTF8. I altered the instance to use UTF8 and ran into a CLOB problem. We installed patchset 4 (so we are now 8.1.7.4.0 on Sun Solaris 2.8) and that problem went away. However, none of the CLOB data is rendered properly in the application and I don't have a tool that allows me to see it directly out of the database. I am tempted to try to change the character set to WE8ISO8859P1, as the vendor requested, with the hope that any deficiencies in that character set have been handled by their product.

Re: Another Character Set Problem
This command is NOT supported by Oracle and Oracle would not guarantee that your data is not corrupted -- particularly if you have not run the character-set-scanner to verify it.

RE: Another Character Set Problem
The utility is called csscan for character set scan. It runs at the unix prompt with additional parameters (some optional and some not) much as export or import would. Before you use it the first time, you need to run csminst.sql from $ORACLE_HOME/rdbms/admin to set up the work tables, etc. Cherie Machler Oracle DBA Gelco Information Network Ron/Sarah YountTo: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] ronwy@SWBELL. cc: NET Subject: RE: Another Character Set Problem Sent by: [EMAIL PROTECTED] om 09/12/02 09:23 PM Please respond to ORACLE-L Scott, 1) I have to agree with Oracle's statement that you need to have a UTF8 database to handle Chinese and Japanese characters.

Re: Another Character Set Problem
Scott, You can only use the alter database command to move from one character set that is a strict superset of your current character set. You can find lists of superset relationships on Metalink. Search on something like character set conversion and superset or UTF8 and WE8ISO8859P1. You probably realize it but if you are going to use the alter database command to do the conversion, you need to run the character set scan utility csscan first and fix any data exceptions before you actually perform the conversion.Metalink has a couple of good notes such as 123670.1 and 66320.1 on exactly how to do this.
