oracle 11g rac 修改字符集

系统版本:

Oracle Linux Server release 5.7

 

数据库版本：

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 -64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE   11.2.0.3.0     Production
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production

 

查看字符集：

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

USERENV('LANGUAGE')
--------------------------------------------------------------------------------
AMERICAN_AMERICA.AL32UTF8

 

关闭RAC其中一个节点：

[root@rac1 ~]#cd /u01/app/11.2.0/grid/bin/crsctl

[root@rac1 ~]#./crsctl stop cluster

 

在另一个节点查看oracle启动参数：

SQL>show parameter spfile;

NAME                                TYPE                             VALUE
---------------------------------------------------------------------------------------------------
spfile                              string                           +DG1/yoon/spfileyoon.ora

 

若VALUE为空，表示用pfile参数启动，即修改为spfile参数启动：

SQL>CREATE SPFILE FROM PFILE;

SQL>shutdown immediate;

SQL>startup;

 

执行：

SQL>alter system set cluster_database=falsescope=spfile;

关闭数据库：

SQL>shutdown immediate;

SQL>startup mount;

SQL> ALTER SYSTEM ENABLE RESTRICTEDSESSION;
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.

修改字符集：

SQL> ALTER DATABASE character set INTERNAL_USEZHS16GBK;
Database altered.

 

恢复数据库为RAC：

SQL> alter system set cluster_database=truescope=spfile;

SQL> shutdown immediate;

SQL>startup;

 

启动另一节点cluster服务并验证：

[root@rac1 ~]#./crsctl start cluster

 

查看字符集：

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

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