修改oracle字符集

首先在命令中以sys连接上你的oracle数据库，然后执行以下指令

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 AL32UTF8;
sql> shutdown immediate;
sql> startup;


//常见的字符集有：ZHS16GBK,US7ASCII,
