2013-07-29 23:29

要更改NLS_CHARACTERSET的值, 例如要改成 AL32UTF8 , 步驟如下:

以 sysdba 角色進入 sqlplus 之後執行以下

shutdown immediate;
STARTUP MOUNT;
ALTER SESSION SET SQL_TRACE=TRUE;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET INTERNAL_USE AL32UTF8;
ALTER SESSION SET SQL_TRACE=FALSE;
shutdown immediate;
STARTUP;

檢查是否已變更:

SQL> SELECT parameter, value FROM v$nls_parameters WHERE parameter LIKE '%CHARACTERSET';
