5、修改oracle的字符集


注意:修改字符集前需要将表空间进行数据泵备份;

5.1、修改server端字符集:

1、登录到oracle实例查看字符集:

[oracle@slave-node2 ~]$ echo $ORACLE_SID

orcl

[oracle@slave-node2 ~]$ sqlplus sys/123456@orcl as sysdba

SQL> show parameter name;

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

USERENV('LANGUAGE')

--------------------------------------------------------------------------------

AMERICAN_AMERICA.ZHS16GBK

2、修改字符集,依次执行如下命令:

SQL>SHUTDOWN IMMEDIATE;

SQL>STARTUP MOUNT;

SQL>ALTER SYSTEM ENABLE RESTRICTED SESSION;

SQL>ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;

SQL>ALTER SYSTEM SET AQ_TM_PROCESSES=0;

SQL>ALTER DATABASE OPEN;

SQL>ALTER DATABASE CHARACTER SET INTERNAL_USE AL32UTF8;

SQL>SHUTDOWN IMMEDIATE;

SQL>STARTUP;

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

USERENV('LANGUAGE')

----------------------------------------------------

AMERICAN_AMERICA.AL32UTF8

5.2、修改client端字符集:

1、设置client端字符集:

[oracle@slave-node2 ~]$ cat /home/oracle/.bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

export ORACLE_BASE=/application/oracle

#oracl安装目录

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

#oracle路径

export ORACLE_SID=orcl

#oracle启动数据库实例名

export ORACLE_TERM=xterm

#xterm窗口模式安装

export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH

#添加系统环境变量

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

#添加系统环境变量

export LANG=en_US.UTF-8

#防止安装过程出现乱码

export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

#设置Oracle客户端字符集,必须和oracle安装时的字符集保持一致

#将ZHS16GBK改为AL32UTF8,保存退出;

2、生效配置文件:

[oracle@slave-node2 ~]$ source /home/oracle/.bash_profile

5.3、说明:

以上是一个oracle实例的字符集修改,如果有多个oracle实例,需要进入到实例中按照"5.1"步骤执行即可;
