attention please…exp on oracle 11gr2

the reason why some tables have not bee exported is that some tables contains not data,in oracle 11g,the exp tools will not export the table has no data,you need to use expdp.In oracle 11g, exp ignore the table create script or DDL which contains 0 row data.that’s why here comes some “alter table..” section without “create table..” section in front.
