Oracle Server端字符集查询
SQL> select userenv('language') from dual;
USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK
由此可以看出字符集为ZHS16GBK
Server端字符集修改
将数据库启动到RESTRICTED模式下做字符集更改:
$ sqlplus "/as sysdba"
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> alter database character set INTERNAL_USE UTF8;
SQL> shutdown immediate;
SQL> startup;
SQL> exit;
