Agenda

6. Analytics
• Discovery, interpretation, and
communication of meaningful patterns in
data.
• Systematic computational analysis of data
or statistics
• Analysis that “Drives you to Decision”.
• Analysis that “Drives you to
Conclusion”.
– What happened?
– How or why did it happen?
– What’s happening now?
– What is likely to happen next?

7. One thing that is common in all Three stages is “Data”
1. Reporting
– Data about the “Past”
– Data about the “Present”
– Traditional Business Intelligence
2. Prediction
– Data about the “Future”
– Use Predictive Modeling
– Forecast Risk
3. Optimization
– About Desired Future
– Finding Best path
Stages of Analytics
Stage 1 Stage 2 Stage 3

9. Why Analytics for DBA’s?

10. What we do when an Alert is received?
– Acknowledge the Alert
– Assign the alert
– Corrective Action
• Permanent Fix
• Temporary Fix (Workaround)
• A Fix
– Close the Alert
What we Do Not do when an alert is received?
– Why the alert occurred?
– Is it the first time this alert received?
– Frequency of reoccurrence of the alert.
– Result of last fix?
– Can it happen again?
“You cannot Fix or Improve what you cannot Measure”
Tracking and Analyzing Alerts

11. • IT Alerts Dashboard

12. Archive Logs Generation Analysis
• Analyzing excessive Archive
Logs Generation
• Analyzing the patterns and
trends of Logs Generation
• Finding the source of
excessive Redo.
• Planning and Scheduling
Archive Log Backup’s as per
the trends during the Day.
• Adequately sizing your
Archive log destination.

13. •
Archive Log generation Dashboard

14. • Archive logs Generation Dashboard Analysis:
– Archive Logs Generated each Month
– Archive Logs Generated each day
– Archive Logs Generated every hour of the day
– Helps in identifying some abnormal patterns in the Archive Generation
– May lead your investigation for some performance issues
– Can point to the exact time when you had high Log generations.
• Redo Log/Block Change Dashboard
– Take the time of high log generation from the Log Generation Dashboard
– Put the same values in Redo/Block Change Dashboard
– Will give details about top objects according to the Block changes.
– Use those details to check in the application, which module caused this
– Might want to go to Developer Team to check if something got changed with any module
related to these tables/objects
• Links to both of the dashboards:
Archive Log Generation
Object Block Change

15. Application Performance Data

16. How we collect Data?

17. How it helps DBA? – Proactive Monitoring

18. Getting Insights…

19. • I need to know the size of my table 6 months
back…???
• What is growth of my certain application tables?
• What is an average growth of application data?
• is switch from Index scans to FTS is due to
increase in volume of data?
Some More Data….

22. Forecasting – Predicting Future

23. • Custom Made Warehouse tables
• Application’s (Peoplesoft) Repository
• Oracle Enterprise Manager’s Repository
