조치1) sysdba로 로긴하여 아래 구문 실행

SQL> @ $ORACLE_HOME/javavm/install/rmjvm.sql 
SQL> @ $ORACLE_HOME/rdbms/admin/utlrp.sql
SQL> @ $ORACLE_HOME/rdbms/admin/catalog.sql 
SQL> @ $ORACLE_HOME/rdbms/admin/catproc.sql

==> 문제 해결 안됨.

원인) 아래 쿼리를 날렸을때 데이터 타입이 중복되어서 나옴

쿼리)

select distinct(nls_charset_name(charsetid)) CHARACTERSET,
decode(type#, 1, decode(charsetform, 1, 'VARCHAR2', 2, 'NVARCHAR2','UNKOWN'),
9, decode(charsetform, 1, 'VARCHAR', 2, 'NCHAR VARYING', 'UNKOWN'),
96, decode(charsetform, 1, 'CHAR', 2, 'NCHAR', 'UNKOWN'),
112, decode(charsetform, 1, 'CLOB', 2, 'NCLOB', 'UNKOWN')) TYPES_USED_IN
from sys.col$ where charsetform in (1,2) and type# in (1, 9, 96, 112);

결과)

CHARACTERSET  TYPES_USED_IN
----------------- -------------
WE8ISO8859P1      VARCHAR2
KO16KSC5601        VARCHAR2
KO16KSC5601        CHAR

KO16KSC5601        NVARCHAR2

AL16UTF16            NCHAR

조치2) sysdba로 아래 구문들 실행

주의사항)

a) Make sure the parallel_server parameter in INIT.ORA is set to false or it is not set at all.
b) Run the next script in SQLPLUS connected "as sysdba"

SQL> sqlplus /nolog 
SQL> conn /as sysdba 
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP MOUNT;
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
SQL> ALTER SYSTEM SET AQ_TM_PROCESSES=0;
SQL> ALTER DATABASE OPEN;
SQL> COL VALUE NEW_VALUE CHARSET
         SELECT VALUE FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER='NLS_CHARACTERSET';
SQL> COL VALUE NEW_VALUE NCHARSET
         SELECT VALUE FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER='NLS_NCHAR_CHARACTERSET';
SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE &CHARSET;
SQL> ALTER DATABASE NATIONAL CHARACTER SET INTERNAL_USE &NCHARSET;
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP;
-- yes, 2 times startup/shutdown . This is not a typo
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP;

실행중 오류발생)

ALTER DATABASE NATIONAL CHARACTER SET INTERNAL_USE KO16KSC5601
==> ORA-12714: invalid national character set specified

원인)

NATIONAL CHARACTER SET 은 Oracle9i 이후에는 UTF8과 AL16UTF16 만 제공
확인)  

SELECT VALUE 
FROM NLS_DATABASE_PARAMETERS
WHERE PARAMETER in ('NLS_NCHAR_CHARACTERSET','NLS_CHARACTERSET')
결과)

PARAMETER                                  VALUE
---------------------------------- ---------------
NLS_CHARACTERSET                     KO16KSC5601

NLS_NCHAR_CHARACTERSET         KO16KSC5601

조치)

update sys.props$ set value$='AL16UTF16' where name='NLS_NCHAR_CHARACTERSET';

이후 위의 조치2)를 다시실행하면 아래와 같은 결과를 얻을수 있다..
