ORACLE數(shù)據(jù)庫設(shè)置編碼
作者：佚名
ORACLE數(shù)據(jù)庫的設(shè)置是我們都非常關(guān)注的問題，下文對(duì)ORACLE數(shù)據(jù)庫設(shè)置編碼作了詳細(xì)的介紹，希望對(duì)您能有所幫助。
下面為您介紹的是ORACLE數(shù)據(jù)庫設(shè)置編碼，如果您在ORACLE數(shù)據(jù)庫設(shè)置方面遇到過類似的問題，不妨一看。
ORACLE數(shù)據(jù)庫設(shè)置編碼：
- $ 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：新字符集必須為舊字符集的超集，
這時(shí)我們可以跳過超集的檢查做更改(UTF8可以根據(jù)需要更改，如ZHS16GBK)：
- SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE UTF8;
- Database altered.
