questionn on sql ?

A developer used the max_row_per_page configuration set to 50% to apred out the data of a 500 MB table.His boss thought this was a waste of space since the table now took up 1000MB.Why would someone do this?

The same developer created an index on the table using fill_factor of 50%.This caused the index to use twice as many index pages.Why would he do that?

    Why not ask the developer why he did that?

    Hi there,

    what the heck is the "max_row_per_page configuration" ??

    I'm pretty sure that I know quite a bit about segment storage option in Oracle, but this setting is totally new to me.

    Could it be that you mean something like PCTFREE/PCTUSED?

    Usually one might think on trying to influence such low level storage to archieve things like less locking contention on a single block or to avoid chained rows.

    Anyhow, with the advent of ASSM the need for such action has greatly decreased.

    regards,

    Lars
