rac环境下修改oracle数据库字符集为GBK - 数据库编程

今天安装数据库（oracle10.2.0.4）的时候字符集不小心没有改动，导致界面乱码，由于是rac环境和单实例的不太一样

http://blog.csdn.net/rulev5/article/details/7020134

1、查询当前的字符集

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

USERENV('LANGUAGE')
--------------------------------------------------------------------------------
AMERICAN_AMERICA.WE8ISO8859P1

sql> alter system set cluster_database=false scope=spfile sid='jscn1';

红色部分对于单实例的是不要加的，对于rac来说必须加上，不然会报

ORA-12720: operation requires database is in EXCLUSIVE mode

2、停止数据库（rac1和rac2都要停止）

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

3、启动数据库（只在rac1上面操作）

SQL> startup nomount;
ORACLE instance started.

Total System Global Area 1577058304 bytes
Fixed Size 2084264 bytes
Variable Size 436208216 bytes
Database Buffers 1124073472 bytes
Redo Buffers 14692352 bytes
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 database open;

Database altered.

4、修改字符集
SQL> ALTER DATABASE character set INTERNAL_USE zhs16gbk;
sql> alter system set cluster_database=true scope=spfile sid='jscn1';

5、验证（两个节点都要测）

Database altered.
SQL> SHUTDOWN IMMEDIATE;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup;
ORACLE instance started.

Total System Global Area 1577058304 bytes
Fixed Size 2084264 bytes
Variable Size 436208216 bytes
Database Buffers 1124073472 bytes
Redo Buffers 14692352 bytes
Database mounted.
Database opened.
SQL> select userenv('language') from dual;

USERENV('LANGUAGE')
--------------------------------------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

6、启动rac2，验证rac2的字符集（废话，公用一个数据库，当然一样了）

以下为本人原创

今天按照上面blog，成功修改rac环境字符集 oracle 11.2.0.3 select userenv('language') from dual; SIMPLIFIED CHINESE_CHINA.ZHS16GBK 改为： select userenv('language') from dual; SIMPLIFIED CHINESE_CHINA.AL32UTF8 这是rac node1的操作

[oracle@ESCMDB01 ~]$ sqlplus "/as sysdba"
