Indexes? From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Dennis Williams Sent: Friday, December 12, 2008 2:55 PM To: oracle-l@xxxxxxxxxxxxx Subject: Simple insert - 36,000 physical reads List, Oracle 10.2.0.4, Solaris 8 I've found a simple insert that has: 1 execution 2,512,102 Buffer Gets 36,479 Physical Reads 1 Parse call 1 Row This insert statement appears quite a few times in the AWR report, and for the times I see it, the statistics are pretty close to what I've listed. The insert just has a list of columns and a list of values. No subqueries. There is a TO_DATE conversion on two columns.This is a real table, not a view. Does anyone have any suggestions of why a simple insert could cause this much database activity? Thanks to Brandon for suggesting awrsqrpt.sql in response to another question. That is a great tool.
