The "pctincrease" parameter made sense to me in the days before unlimited extents, in the same way "locally managed autoallocate" would make sense to me now - if you have a table that you think is going to be small but you're not sure. In the days before unlimited extents, once you reached the maximum number of extents for a table, you were stuck. Of course nowadays with unlimited extents there is less of a reason to use "autoallocate" than there was to use pctincrease in pre-7.3 Oracle. The "how to stop defragmenting and stop living" paper was originally written before locally managed tablespaces. I remember reading it before 8.1 was released. -----Original Message----- Mercadante, Thomas F As far as I was concerned, it became standard practice back in version 6 or 7. I *never* liked the pctincrease parameter - it never made any sense to me. But I would guess that it generally became accepted sometime around when the paper was published. It was a basic grass-roots-ground-swell type of deal that the paper finally formally published, and Oracle agreed to after the fact. ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
