Linux环境解决Oracle 中文乱码

Linux环境解决Oracle 中文乱码1）查看数据库字符集

03:12:58 SQL> select userenv('language') from dual;
USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

2）编辑linux 的NLS_LANG变量
[oracle@oraserv ~]$ pwd
/home/oracle
[oracle@oraserv ~]$ ls -a

.                      cr_dbprod.sql .gconfd            .ICEauthority .rman_history     .Xauthority
..                     cr_db.sql      .gnome             logmnr         sel.sql           .xsession-errors
.bash_history          cr_dict.sql    .gnome2            .metacity      sql.log           中国
.bash_logout           Desktop        .gnome2_private    .mozilla       sqlnet.log
.bash_profile          .dmrc          .gstreamer-0.10    .nautilus      .sqlplus_history
.bashrc                .eggcups       .gtkrc-1.2-gnome2 ora.sh         s.sh
close_bak_command.sql ftp.msg        hot_bak_cmd.sql    ora.txt        start.sh
cold_bak.sql           .gconf         hot_bak.sql        .redhat        .Trash

[oracle@oraserv ~]$ vi .bashrc

# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

".bashrc" 10L, 167C written

3）注销oracle用户，重新登录

[oracle@oraserv ~]$ su - oracle
[oracle@oraserv ~]$ env |grep LANG
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
LANG=en_US.UTF-8

[oracle@oraserv ~]$ export ORACLE_SID=prod
[oracle@oraserv ~]$ env |grep LANG
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
LANG=en_US.UTF-8

通过sqlplus验证：
[oracle@oraserv ~]$sqlplus '/as sysdba';

注意：解决问题的原则，客户端的字符集和oracle 数据库的字符集保持一致。
