EXP00091: Exporting questionable statistics.

1、查看oracle server NLS_LANG参数信息；以SYSDBA身份登录

SQL>  select * from v$nls_parameters where parameter='NLS_CHARACTERSET';

PARAMETER                      VALUE
------------------------------ ------------------------------
NLS_CHARACTERSET               AL32UTF8

2、修改环境变量

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

ORACLE_BASE=/RealData
ORACLE_HOME=$ORACLE_BASE/oracle
ORACLE_SID=DATACENTER

PATH=$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

DISPLAY=192.168.1.168:0.0
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH DISPLAY

alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'


#add enviroment variable nls_lang
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

3、导出数据文件

[oracle@arcerzhang ~]$ exp ARCER/ARCER file=/RealData/backup/3.dmp
