set nls_lang='SIMPLIFIED CHINESE_CHINA.ZHS16GBK'
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>ALTER DATABASE CHARACTER SET ZHS16GBK;
如果出现了 ERROR at line 1: ORA-12712: new character set must be a superset of old character set
SQL> ALTER DATABASE character set INTERNAL_USE zhs16gbk; # 使用INTERNAL_USE可以跳过超集的检查,
ALTER DATABASE character set INTERNAL_USE
SQL>SHUTDOWN IMMEDIATE;
SQL>STARTUP 再检查就发现已经把字符集修整过来了
