java调用shell脚本执行impdp命令

脚本内容：

一、导出

1、库模式：整个数据库：

2、用户模式：

EXP CFG/CFG@ZQCREDIT BUFFER=64000 FILE=C:\CFG.DMP OWNER=CFG

3、表模式：
exp bsd/bsd@JSCREDIT_142 file=D:\数据文件备份\JSCREDIT_BSD_20151231_2.dmp log=D:\数据文件备份\JSCREDIT_BSD_20151231_2.log TABLES=(CORP_ATTEND_DETAIL,CORP_PRESON_FINGERIMG)

没有配置tns文件的方式：

exp bsd/bsd@IP/DBNAME file=D:\数据文件备份\JSCREDIT_BSD_20151231_2.dmp log=D:\数据文件备份\JSCREDIT_BSD_20151231_2.log TABLES=(CORP_ATTEND_DETAIL,CORP_PRESON_FINGERIMG)

限制数据行：

EXP name/pwd@MYDB FILE=D:\XXX.DMP LOG=D:\XXX.LOG TABLES=(DW_MDY_QYSPECIALCHECKINFO, DW_MDY_QYBADCREDITINFO) query=“‘where rownum<=100’”

二、导入
1.登录 linux
oracle su - oracle -c
2. 进入目录 /home/app/oracle/product/11.2.0/db_1/bin/ bin路径 执行
su -oracle -c "/home/app/oracle/product/11.2.0/db_1/bin/impdp 用户名/密码 director=DUMP1 dumpfile='文件路径' remap_schema=SBOD_WBEP:DATA_IMPORT remap_tablespace=SBOD_WBEP:DATA_IMPORT logfile='存储日志文件路径'"

imp导入模式 IMP NAME/PASWD@DBSHILIE FILE=D:path\DW.DMP BUFFER=64000 TABLES=(table1,table2)
