Oracle 字符集 简体中文 转换 UTF8

只需在 sqlplus 连接上Oracle 后执行以下命令即可

SQL>SHUTDOWN IMMEDIATE;

SQL>STARTUP MOUNT EXCLUSIVE;

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 NATIONAL CHARACTER SET INTERNAL_USEUTF8;

SQL>SHUTDOWN immediate;

SQL>startup;

如果按上面的做法做,National charset的区域设置就没有问题
