RE: SORT_AREA_SIZE question

Bart
 
Each user which connects to the DB will consume that amount of RAM on top of any memory used by the application.  A lot depends on how much memory your server has i.e. 10 users will use at least 1Gb of RAM.  It could induce swapping which is a killer.  
Our DSS systems use 20Mb for sort area mind you we have 18Gb temp tablespace

  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
