语言_地域.字符集SIMPLIFIED CHINESE_CHINA.ZHS16GBK set nls_lang=

语言_地域.字符集
SIMPLIFIED CHINESE_CHINA.ZHS16GBK


set nls_lang='SIMPLIFIED CHINESE_CHINA.ZHS16GBK'


Oracle修改服务器端字符集:
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>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


NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
