I am trying to size my undo tablepsace by looking at the undo rates.i.e the column UNDOBLKS in v$undostat.

Value for undoblks for particular sql is 13841 and my database size is 8kb.Does this mean that i need to have a undo tablespace size of

select 8192*13841/1024/1024 from dual
108Gb ?

Not the particular sql does a corelated update ofmere  72762 rows and the figure of 108Gb doesnt make much sense .This is a JDBC app and i dont have much idea if this sql is in some for loop or something.
