设置改变oracle字符集

 

修改过密码之后就能以dba的身份进行修改了,不是dba的话在执行修改命令的时候会提示你权限不足.

开始-->运行-->cmd,之后输入:" sqlplus sys/[email protected]/orcl as SYSDBA"

如果不能正常进入,那就需要你手动输入用户名和密码,进入之后会出现

"SQL>"的提示,

按照下面给出的命令依次执行就可以了,

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 ; ALTER DATABASE CHARACTER SET ZHS16GBK *ERROR at line 1: ORA-12712: new character set must be a superset of old character set

报字符集不兼容，此时下INTERNAL_USE指令不对字符集超集进行检查：

SQL>ALTER DATABASE CHARACTER SET INTERNAL_USE ZHS16GBK; SQL>SHUTDOWN IMMEDIATE SQL>STARTUP
