Re: SQL*Loader performance - PCTFREE
Date: Thu, 17 Jan 2008 17:11:41 -0600
I just thought about something else. We currently have pctfree set to 40 in the largest of the tables. This was done a few month ago to deal with Oracle not being able to build bitmap indices on this tables because they were too
fragmented. To reduce the number of records per block I have increased the pctfree to 40. This increased the
number of blocks needed to store the table. Now I don't think we have any more of the bitmap indices and therefore I should be able to reduce the pctfree thus reducing the size of the table and this should reduce the time needed
to load this table.
Does that sound reasonable?
