5.开始导入

impdp NJ_OPERATION_USER/NJ_OPERATION_USER dumpfile=NJ_OPERATION_DEV_USER.dmp directory=ora_back remap_tablespace=NJ_OPERATION_DEV_DATA:NJ_OPERATION_DATA remap_schema=NJ_OPERATION_DEV_USER:NJ_OPERATION_USER schemas=NJ_OPERATION_DEV_USER table_exists_action=replace transform=segment_attributes:n;

把NJ_OPERATION_DEV_USER导入到NJ_OPERATION_USER
