ORACLE数据库设置编码
下面为您介绍的是ORACLE数据库设置编码，如果您在ORACLE数据库设置方面遇到过类似的问题，不妨一看。
ORACLE数据库设置编码：
- $ sqlplus / as sysdba
- SQL> SHUTDOWN IMMEDIATE;
- Database closed.
- Database dismounted.
- ORACLE instance shut down.
- SQL> STARTUP nomount;
- ORACLE instance started.
- SQL> ALTER DATABASE mount exclusive;
- Database altered.
- SQL> ALTER SYSTEM enable restricted session;
- System altered.
- SQL> ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
- System altered.
- SQL> ALTER SYSTEM SET AQ_TM_PROCESSES=0;
- System altered.
- SQL> ALTER DATABASE OPEN;
- Database altered.
- SQL> ALTER DATABASE CHARACTER SET UTF8;
- ERROR at line 1:
- ORA-12712: new character set must be a superset of old character set
提示字符集：新字符集必须为旧字符集的超集，
这时我们可以跳过超集的检查做更改(UTF8可以根据需要更改，如ZHS16GBK)：
- SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE UTF8;
- Database altered.
