Hey Bart,

You'll probably get a lot of responses from this, but my little piece of input starts with a question...
Is this database a 9i version? If so, do some research on pga_aggregate_target. It lets Oracle do some of that *_area_size guess work for you.

Hello,

I joined this list last week, so I apologize in advance if I'm asking a question that has previously been answered.

I am responsible for a reporting database/data mart that is approximately 175 GB. Our main fact table ranges from 1-14 GB depending upon how far along we are into our financial year. I have large reports that run full table scans on this table daily. In an effort to keep as much of the sorting in memory as possible I have specified SORT_AREA_SIZE to be 100MB. Some of the tuning books I am reading now are making me second-guess myself and I am wondering if this is overkill.

Can anyone provide some advice on how large they are setting their SORT_AREA_SIZE values for their DSS systems?

Thanks in advance,

Bart
