oracle 11g rac 修改字符集

系統版本:

Oracle Linux Server release 5.7

資料庫版本：

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

檢視字符集：

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

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

關閉RAC其中一個節點：

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

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

在另一個節點檢視oracle啟動引數：

SQL>show parameter spfile;

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

若VALUE為空，表示用pfile引數啟動，即修改為spfile引數啟動：

SQL>CREATE SPFILE FROM PFILE;

SQL>shutdown immediate;

SQL>startup;

執行：

SQL>alter system set cluster_database=false scope=spfile;

關閉資料庫：

SQL>shutdown immediate;

SQL>startup mount;

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.

修改字符集：

SQL> ALTER DATABASE character set INTERNAL_USE ZHS16GBK;
Database altered.

恢復資料庫為RAC：

SQL> alter system set cluster_database=true scope=spfile;

SQL> shutdown immediate;

SQL>startup;

啟動另一節點cluster服務並驗證：

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

檢視字符集：

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

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