RE: AUTOALLOACATE vs. UNIFORM extent size in Oracle10g

Tom Kytes suggest the same.

Can you explain what happens when there is a queue table where the extents are at 1M or 8M and old data deleted are from 64K extents.

Will those 64K extents be used if let's say no new tables are created and will this cause a little waste in storage.

Thanks in advance for your response.

I'd would recommend AUTOALLOCATE over UNIFORM unless you require very large extents (>64MB). If require larger extents for a segment, just use the INITIAL attribute.
