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.
