Performance Tuning :: AWR Report Evaluation
May 20, 2010My DB is oracle10g.
I have AWR report comparison for two different days. I want to find the below things.
1. Which day has better performance?
2. What are the top two findings on the report.
I attached the report.
Here are my answer. Please correct me if i am wrong.
1. Which day has better performance? Second day has higher load. Since redosize is showing very high.
2. What are the top two findings on the report.
a) Compared to two days, first day, little bit more I/0 wait for single block read.
b) Compared to two days, 2nd day, it takes higher CPU.
However, which day is best compared to two days?

Performance Tuning :: Get AWR Report Data?

View 6 Replies View RelatedPerformance Tuning :: Time Calculation In AWR Report
Dec 12, 2011Till statspack we had
elapsed time = time spent on waits + time CPU was used
Total time during snaps = Elapsed time + (may be) time waited for CPU...In AWR is it possible to draw such equation? I can see that the AWR report has following elements
1) End Snap time - Begin Snap time
2) DB time - as mentioned at the top of AWR report
3) DB CPU - in "Top 5 Timed Foreground Events" (I assume this is 'CPU used by sesson timing' in statspack)
4) Total of time for all Statistics in "Time Model Statistics"
5) BUSY_TIME + IDLE_TIME - "Operating System Statistics"
Time between 2 snapshots? or what else? Also for which seconds to multiply to 'DB Time(s)' per second and 'DB CPU(s)' per second in Load Profile to get the db time and CPU time?

View 6 Replies View RelatedPerformance Tuning :: Database Time In AWR Report
Jul 9, 2012I understand that when data is read from the disk, I/O is done..And When computations are done then CPU is used..Then where the following equation fits?

Is I/O considered as a part of CPU time?
Does this equation changes with SAN, OS caching?

View 1 Replies View RelatedPerformance Tuning :: Oracle Documentation On Details Of AWR Report
Jun 4, 2012A coworker of mine asked if there was any documentation from Oracle that listed all of the parts of the AWR report and what each meant. I was taken back because I don't think there is. There are third party books that talk about AWR reports and their predecessor Statspack reports.
Oracle has some notes on their support site about reading an AWR or Statspack report. All I found in the official documentation was some basic information about how to run an AWR report and an overview of what it was. It would be nice to have some sort of documentation that lists out each section and explains the units and purpose.

Performance Tuning :: Query Not Hitting Index On Date Column
May 18, 2012I am working with following select clause:
select distinct S.ID ID
from
ods.hso_Scheduled H,
ods.SO_SCHEDULED S
where
S.insertion_date >= to_date('01-DEC-2011') and S.insertion_date < to_date('01-FEB-2012')
and H.ID=S.ID
Both the involved tables, HSO_SCHEDULED is having 15 million records and SO_SCHEDULED table is having 7 million records.
I have created following indexes on these tables:
Indexes on SO_SCHEDULED:
Index name Column name
SS_IDX1ID, SO_SUB_ITEM__ID
SS_IDX2INSERTION_DATE
SS_IDX3ID, INSERTION_DATE
SS_IDX4ID, SO_SUB_ITEM__ID, INSERTION_DATE
SO_SCHEDULED_ID_PKID
Indexes on HSO_SCHEDULED:
HSS_IDX1ID, SO_SUB_ITEM__ID, LAST_UPDATING_DATE
HSS_IDX2ID, LAST_UPDATING_DATE
HSS_IDX3ID
My problem is despite of having relevant indexes present, my query is not hitting them and hence the performance is very bad.

Performance Tuning :: Tools For Database Tuning And Instance Tuning
Jul 12, 2010Looking to understand the difference between instance tuning and database tuning.
What is the difference between these two tuning exercises? I understand that an instance is memory based structures (logical) where as database consists of physical structures.
However, how does one tune a database the physical structure? Does it have to do with file placements/block sizes etc. Would you agree that a lot of that is taken care by ASM now in 11g? What tools are required/available (third party as well as oracle supplied) for these types of tuning scenarios?
