Linux下修改Oracle数据库字符集命令

常见情形:从服务器备份oracle后再到本地机器上还原oracle数据库的时候经常会碰见数据库字符编码不一致的情况，可以用以下命令来修改本地的oracle数据库字符编码，然后顺利还原oracle数据库到本地机器上

操作指令：

sql> conn /as sysdba;

sql>select userenv('language') from dual;

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 us7ascii;

sql>shutdown immediate;

sql>startup;

sql>select userenv('language') from dual;

常见的oracle字符集有zhs16gbk、al32utf8、us7ascii等?
