AWR Review Checklist
Snapshot Range Reviewed (Begin Snapshot ID - End Snapshot ID): _____________________________
Time Window (Start Time – End Time): _________________________
- SYSTEM LOAD
- DB Time per Second:
- Value: ________ — Is it high for this system?
- CPU Usage per Second:
- Value: ________ — Is DB Time >> CPU time? Suggests waits.
- Executions per Second:
- Value: ________ — Is there a spike or dip?
- DB Time per Second:
- TOP WAIT EVENTS
Wait Event Time (s) Notes [ e.g., temp spill, I/O, locking ] 1. 2. 3. - TOP SQL STATEMENTS
SQL_ID Metric Value Comment (slow/overused/etc.) Elapsed Time Buffer Gets Executions - TEMPORARY SPACE USAGE
- Temp Waits (for example, direct path read/write temp):
- Observed? Yes / No
- Notes: ___________________________________________
- Operations likely causing spills (sorts, joins, and so on): ___________________________________________
- Temp Waits (for example, direct path read/write temp):
- INSTANCE EFFICIENCY RATIOS
- Buffer Cache Hit Ratio: _________ %
- Parse to Execute Ratio: _________ (High = too many hard parses?)
- NOTABLE CHANGES COMPARED TO BASELINE
Area What Changed Details Workload Increased / Decreased Waits New / Increased Top SQL Changed / Same - INITIAL CONCLUSION / NEXT

(for example, Investigate temp usage, tune top SQL, compare plans, escalate to support)
