Steps to Troubleshoot Database & SQL Performance

edited Apr 9, 2013 9:08PM in Database Tuning (MOSC) 3 commentsAnswered
Hi Experts,

I see lots of performance issue in datawarehouse database and on other oltp database.
I see , the possible cause of poor sql statements, statistics , wait events(db_sequential_read) & cpu time based on AWR report.

I am trying to troubleshoot these issue in following method, however, am still not able to crack the exact bottleneck of the performance issue

1. Run addmrpt.sql to find what is currently going on with possible recommendation.  --> Recommendation from addm is not straight forward,rather it does not help much

2. Run AWR report between the performance period  --> This gives overall picture, however, i dont see which sql caused most performance issue ,what is possible recommendation.

Howdy, Stranger!
