export ORACLE_BASE ORACLE_HOME ORACLE_SID NLS_LANG LD_LIBRARY_PATH PATH

字符集是US7ASCII，怎样设置为ZHS16GBK（是否这样写）呢？
请大家帮帮忙吧，多谢了

c:>svrmgrl
在svrmgrl中执行：
shutdown
startup mount
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
update props$ set value$='ZHS16GB' WHERE NAME='NLS_CHARACTERSET';
update props$ set value$='ZHS16GB' WHERE NAME='NLS_NCHAR_CHARACTERSET';
先申明此法很危险，
如果改错了值可能会导致数据库无法打开。

修改字符集的步骤：
c:>svrmgrl
在svrmgrl中执行：
connect internal/oracle[@dbname];
shutdown immediate;
startup restrict;
ALTER DATABAE [dbname] CHARACTER SET [SIMPLIFIED CHINESE_CHINA.]ZHS16GBK ;
ALTER DATABAE [dbname] NATIONAL CHARACTER SET [SIMPLIFIED CHINESE_CHINA.]ZHS16GBK ;
alter database [dbname] open;
--shutdown immediate;
--startup;
