can any one help on this please.

There is no function CEILING that is part of any stock Oracle database install of any version.
If you are using a function CEILING in your 10g database, that implies that it is a user-defined function. If that function doesn't exist in 11g, you'd need to create it there.
Oracle does have a function CEIL that takes a number and rounds up to the next highest integer. If that's all you are doing, it probably makes more sense to use the built-in function rather than writing your own wrapper function.
