  • 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=false scope=spfile;

    关闭数据库:

    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.

    恢复数据库为RAC:

    SQL> alter system set cluster_database=true scope=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
