完整的解决oracle乱码shell处理(当每日导入数据库是英文字符集但需要导入中文字符集并且显示中文)

1.gs_o_convert.sh

#!/bin/sh
ORACLE_BASE=/home/oracle;export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/9.2.0;export ORACLE_HOME
ORACLE_SID=test;export ORACLE_SID

echo "extract ok" >> $exp_dir/log
#删除已经导入的表

2.convert_to_en.sh

#!/bin/sh
sqlplus "/ as sysdba"<<!
shutdown immediate
STARTUP MOUNT;
--alter session set sql_trace=true;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
alter database open;
ALTER DATABASE character set INTERNAL_USE us7ascii;
SHUTDOWN IMMEDIATE;
STARTUP
exit

3.convert_to_cn.sh

#!/bin/sh
sqlplus "/ as sysdba"<<!
shutdown immediate
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE character set INTERNAL_USE  ZHS16GBK;
SHUTDOWN IMMEDIATE;
STARTUP
exit

4.drop.sh

#!/bin/sh
#删除以下表
#Written by Chameleon
sqlplus 'back/backpass'<<!
drop table gs_o_ms_isdn_segment;
drop table gs_o_act_config;
drop table gs_o_mms_act_config;
drop table gs_o_sms_infocode;
exit

＃＃说明：这个一个完整的例题，使用的是一台转码服务器来处理的数据后并上传到其他服务器并进行导入
