Hi ,

Without estimating i gave the storage parameter to the tables, But Now i feel that (performance is very slow ) I need to estimate the amount of data to be loaded for a particular table.
I have very little knowledge ,that PCTFREE space is used for update the row data in a table like that.
I want to know the effect of other storage parameter, Intial,extents,optimal etc. & how to calculate the parameter values.
